[split inlet]

How would I go about this besides playing one grass at a time

[desert rock]

use polybrush to scatter prefabs on any mesh

[cedar basalt]

how to understand how to put togheter a beutful simple level with assets.

[nova perch]

any1 know how to use this as a detail mesh? you have to have exactly one material but my prefab isn't li ke that

[rancid nimbus]

great question, I m a beginner myself and I cant find many resources either

What helped me a bit was this video, he plays around with shadow settings, fog, lighting etc
https://www.youtube.com/watch?v=IotV3yHAdJ8

Its not much bit its something

If you find out what the magic trick for making simple but good looking levels is, let me know

[cedar basalt]

there are enough assets. i'm talking about more put it togheter for a level.

[last linden]

You have to look at it from a different angle that's why use of Level blocking is preferred as you don't get blinded by the assets themselves you make a blockout then make it look good with assets

grass that i painted with the terrain tree paint becomes so much big when i move the terrain any idea why ?

hmm i noticed the scale on the model itself is not 1 so maybe that's the issue

Edit: making the model 0.01 in import settings and 1 in model fixed it

now when i move the terrain the detail doesn't become big

[rancid nimbus]

I wasnt talking about assets, I was talking about making them look good

[snow hare]

can you have a 4097x4097 heightmap on a 2048x2048 terrain
and will it result in better quality or smth

and what is a pixel error

[civic carbon]

The terrain just reads the interpolated pixels of the texture. So if the terrain and the texture are the same size, then it will sample every 1 meter basically. If the texture is 2x the size, it will sample 2 times every 1 meter, etc.

[snow hare]

so well, terrain will have "better quality"

i mean more triangles or smth

[civic carbon]

No, just more accurate.

[snow hare]

does it affect performance somehow

or read operation is done once when building the terrain

[civic carbon]

Bigger texture worse performance when editing. Not sure how much of a difference it makes at runtime. I am pretty sure that it is a one and done sort of thing. But you would have the memory overhead of having the texture loaded

[snow hare]

well, it's only a single terrain

shouldn't really eat much memory

i'm currently building up a large terrain out of small pieces

each piece has 64x64 size and 65x65 heightmap

i collect the pieces into a single terrain with 2048x2048 size and 2049x2049 heightmap

if i instead have 129x129 heightmap on each 64x64 piece and 4097x4097 heightmap on resulting 2048x2048 terrain, will the output be more accurate?

[snow hare]

if it's true, then i'm definitely switching to higher resolution approach

[snow hare]

also

i kinda don't get it from wiki

[tight tide]

Is there an easy way of creating a sloping terrain instead of manually painting it? I'm just wondering if I'm doing this right

[solar swan]

Use a stamp/brush with a ramp mask. There are also some assets floating around that allow you to create the terrain displacement from meshes, like a blanket dropped onto objects.

[tight tide]

I did use the stamp but it has a lot of waves because it is too large, pixel is having a problem. But i didn't know about the blanket thing, thanks!

[solar swan]

Have you tried a large (2k+) 16bit mask for your stamp?

[nova heron]

Does anyone know how to create tiles that dont end up looking like squares? How can I make them transition smoothly to each other?

[winter minnow]

They could be authored using repeating patterns to begin with, either from procedural algorithms or a tiled paint mode the likes of which photoshop and Aseprite have
But there's also a technique to paint over the seams with an offset version of the texture itself

[charred jolt]

GetInterpolatedNormal seems to point along the terrain instead of perpendicular, is that supposed to happen?

var normal = _terrain.terrainData.GetInterpolatedNormal((x + halfSize) / _terrain.terrainData.size.x, (y + halfSize) / _terrain.terrainData.size.y);

grass.transform.rotation = Quaternion.LookRotation(normal);

This makes the object face along the terrain

[charred jolt]

I'm adding halfSize because my terrain is centred so it adds half of the size of the terrain

[slow relic]

hey

can any one tell me how to fic this

i want to so that thw wall whould appear on top of the ground tiles and not just deleate the ground tiles

[winter minnow]

A single tilemap can have only one tile per grid cell, so you need another tilemap on top
Or for your wall/floor tiles to also include the background in their sprite
#🖼️┃2d-tools next time

[slow relic]

ok

[green gorge]

Hello! Can anyone tell me waht is happening here? I am using a simple directiona llight on a terrain with fast trees and grass meshes paited atop of it. They don't seem to get shadows cast on them though.. Does anyone know how to fix this issue?

[rotund forum]

is there a way to make asset pallets in terrain similar to the polybrush?

[torpid oasis]

verify you use a lit shader, also verify on some components (maybe the mesh renderer or the terrain) that it can receive shadows

[vagrant bough]

hey im trying to set up my tree (improted as an fbx) and at first the tree couldnt be instance bc of no valid mehs renderer but then i found an solution on reddit saying to create a prefab of the model with an mehs renderer and an lod group. somehow this worked for one model but my other model gets another error: the tree couldnt b instanced because one material is missing. but there shouldnt be a missing material actually

[manic cairn]

Can somebody help me with procedurally generated terrain

[cosmic hawk]

Look into stuff like height maps noise and unity terrain

[manic cairn]

Cool thanks

[snow hare]

I'm still on my large terrain with high view distance problem

Anybody has a clue how to make 6144x6144 terrain while still having good splatmap which isn't squared like on this picture, and also display far-away mountains lods(like 4k units away from player)

[winter minnow]

You would want to use neighbor terrains rather than one extremely huge one with a massive resolution

[snow hare]

How much terrain pieces i can have without unity dying cuz it has to process exsitance of many terrain/terraincollider components?

And if there are many terrains, how do i hande runtime splatmap/heightmap rebuilding so terrains get higher-res maps only when i approach them

for heightmaps i can probably store refs to .raw, and well, apply it to the terrain

but for splatmaps with all those layers idk what to do

for 6144x6144 world coverage i use 12x12 grid of 512x512 terrains

and each of those 144 terrain has 4k splatmap

[snow hare]

9216 cells of 64x64 size Xd

if i cant use primary size, then i need to combine heightmaps of cell grids to a larger chunk

but in that case combining splatmaps is gonna be painful

because each individual 64x64 piece has own set of layers

[solar swan]

Unity and editor performance dies primarily because of the insane memory requirements that terrains have.

144 terrains with 4K splats alone are 2.8 GB (and this doesn’t count mips). These maps also cannot be streamed or compressed.

unity terrain works best when there is just 1 terrain. That’s what it was originally designed for. Any adjacent chunks you may have loaded need to have their full set of maps and textures loaded and render their full shader. If they don’t share the same shader, your perform dies potentially because of the texture sample counts which can go crazy if you use anti tiling tricks, many layers or stuff like POM

If you want to do proper world streaming with actual terrain LOD and assets loading incrementally you pretty much have to rebuild the entire terrain engine or spend equivalent time on coercing the builtin system to approximate what you need

4K splat on 512 unit terrain size is quite extreme (.125 unit resolution), 0.5 units would be more sensible. AAA doesn’t go beyond .25 either

you gain nothing from that kind of texture placement resolution. All that detail should come from height blending, detail meshes and overall clever texture design

[snow hare]

this is 2k splat on 512 terrain

well, it's an equivalent

256 splat on 64 terrain

and this is 512

it's quite hard to see the blocky thing

[solar swan]

you are doing it wrong

This is not how you are supposed to use splat maps

[snow hare]

well, then how am i supposed to use them

[solar swan]

Make a transition zone where both textures fade into each other

[snow hare]

how

[solar swan]

turn on height blending

[solar swan]

By painting with a soft brush

[snow hare]

i now have 1 layer

added second one

set resolution to 128 instead of 512 just to test

and painted a road diagonally

[solar swan]

The blend are must be wider

[snow hare]

blend what?

[solar swan]

Grass/road

And you don’t need to scale down the texture, just the splat

[snow hare]

i only scale down splatmap res

textures are all 1k

1024x1024

kinda many squares

[solar swan]

Use a softer brush

[snow hare]

which one

and with which settings

i tried different brushes, but it's still squared

some parts are kinda covering transitions, but with transparent version of the texture

[snow hare]

alr i found out how to make it look great on .5

[opaque rover]

OK so what is my best option for painting a giant terrain mesh?

It would be blocked out via digger, exported (only the underground section), then sculpted further in blender, then I'd need a way to texture it

I know painting a texture for it in substance painter doesn't work because the mesh will be too big

I'd love to paint it unity terrain style with splat maps

as far as I've seen, I am able to do it with this
https://assetstore.unity.com/packages/tools/painting/microsplat-mesh-workflow-120008

[cosmic tinsel]

why is my grass lying down?

i want it to look lik this

[snow hare]

make sure your prefab is rotated properly

in blender if you do it there

since YZ are flipped there

[solar swan]

For large terrains you’d typically use a combination of procedural generation and manual painting&sculpting in multiple passes. You start with a manual layout, potentially sculpted in blender, feed that into a procedural terrain generator like gaea/world-machine for erosion and mask/map creation, then bring that into unity and do local modification around your gameplay/objects, typically via procedural tool like microverse (biomes, texturing, roads, rivers, object scattering), then finally do more manual local adaptations via painting. In all these steps splat map texturing is a side-product. there is typically no manual direct painting of splat maps due to the burden that such a destructive manual process would be.

[opaque rover]

It's a cave tho so nothing other than texturing would be needed

I can sculpt it myself

I would be able to do all this with digger, no exporting anywhere, but the digger shader doesn't work with unity 6 unfortunately

[solar swan]

you'd want to use microsplat anyway. which works for 6000 and replaces the digger shader, but it'll cost ya dearly to get all the nice stuff.

[opaque rover]

as far as I know

I only need the digger integration + hdrp support asset

no?

[solar swan]

yes, but then you won't have all the nice stuff

[opaque rover]

Lol like what

I don't know that I need anything more

[solar swan]

anti-tiling, triplanar shading, mesh terrains, tesselation/POM, object-terrain blending

[opaque rover]

Triplanar shading sounds good

But I don't think I need anything more

[coarse lava]

Please suggest how I can improve on this

when I add too much grass or trees, my PC is unable to handle.. so please suggest low performance improvements

[snow hare]

so is there anything i can do to actually create a 6144x6144 world

[winter minnow]

I think Anikki listed all your practical options

1. make your own terrain system that supports chunk loading
2. figure out how to get the builtin terrain to do chunk loading
3. try and see if you can make one big terrain work, but reduce resolutions and use softer brushes to hide the jagged edges

[snow hare]

by chunk loading you mean some parts of the world are not loaded/rendered at certain conditions?

[winter minnow]

Yes

In many games you might only see the tile you're in and ones next to it so ones beyond that don't have to exist at all at that time

Or you may see the further tiles (or all tiles) from afar so only low LOD levels need to be loaded (as well as low mip levels but that might require "virtual texture streaming")

[snow hare]

well, speaking about lod levels

aren't far away tiles also terrains

or they are meshes

i mean in case i have 64x64 tiles for 6144x6144 world then total amount of them is ~9200

9200 terrains is too much for unity to handle

[winter minnow]

By "64x64 tile" you mean 64 unit wide terrain?

[snow hare]

yeah

i don't connect splat or heightmaps rn

just the size

[winter minnow]

That seems quite small
A terrain is already internally broken into tiles with their own LODs

LODs can be used for all meshes, not just terrains

[snow hare]

so what's the preferred terrain size and what's the preferred heightmapres / terrainres

[snow hare]

i mean distant lands LODs

not distant rocks or houses

Anikki said that 2/1 is optimal and 4/1 is like AAA-game stuff

[winter minnow]

That's probably the ballpark estimate
But note that triple-A games have much heavier optimizations than what unity terrain can offer

You don't generally expect to make a full open world with the terrain system

[snow hare]

so well, terrains are not for me

have to write smth to suit my 6144x6144 needs xD

or 4096x4096 or 7168, or 8192...

or for sub-worlds 1024/2048

[cosmic tinsel]

okk

[solar swan]

Do you have some sort of trick or clever idea how to fill such a huge world with content? That’s basically the size of GTA5

[snow hare]

i'm doing a proof-of-concept demo

[solar swan]

proof of what?

[snow hare]

large terrain in unity

with decent graphics

[solar swan]

you can’t prove that without content

the limiting factor here is lack of editor support for managing this kind of world, not the render performance of terrain meshes

the editor performance will die long before you have filled a 2k map with detailed content

provided you have the memory you can easily render a 8k map with 0.25 m resolution

you just can’t fill it with content unless you heavily reuse models and textures and build tools for managing the chunks in the editor.

[snow hare]

well, basically i decided to achieve same things bethesda achieved in 2013...

large world + modding

[snow hare]

well, it's 3 fps when i play it

so performance is a limiting factor

[solar swan]

looks like you don’t have the memory then

(in you gpu)

[snow hare]

well, when i play skyrim, it feels like i have memory

[solar swan]

Skyrim doesn’t use Unity and has proper asset streaming

it doesn’t need to load the whole world at once like vanilla Unity does

[snow hare]

yeah, but it's devkit is straight from 2005

with some upgrades to 2013

and unity 6 is 2024...

[solar swan]

why does it matter when it was made?

It’s not a technology issue, it’s an architecture issue

Unity is a generic engine for all sorts of compact games . Creation engine is made specifically for open world Bethesda style games

unreal didn’t support open world streaming either before 5.0

[snow hare]

well, skyrim is not using advantage of multiple cores, it doesn't support ray tracing, it's scripting language is relatively slow, it's CK is slow and has a lot of limitations, which require giant libraries to be written to add support for some functionality, game doesn't support compute shaders and so on...

[winter minnow]

How's that relevant? Each game supports the features it needs

[snow hare]

so well, games made on unity 6.0 in 2024 might give out more performance than skyrim while keeping same world size(6kx6k)

[snow hare]

i never used world streaming and idk what it really is

[snow hare]

well, modders have kinda different opinion

they add things which were not possible back then

[winter minnow]

Daggerfall in 1996 had a world size equivalent to 314 000 x 530 000 units

[snow hare]

well, it loads the world partially

[winter minnow]

Daggerfall was also ported to Unity

[winter minnow]

So I expect you will have to, too

[snow hare]

Well, skyrim keeps the entire 6kx6k terrain visible every frame

it uses fog to hide low quality of LODs, but it has tons of lod meshes existing at the same time

so well, equivalent to 9216 low-res terrains

except some terrains which are relatively close are not LODs but actual terrains with colliders and high resolution textures, which calculate the "life" of npcs, not fake it

and my question is how can i make a game which also keeps the entire landscape visible from any point, but also have beautiful landscape textures, and more than 1 fps

i tried 9 2048x2048 terrains to fill the world up and it gave me desired 150+ fps

but i kinda didn't like the 4k splatmap resolution, it felt to squared for me

[winter minnow]

The "distant land" lod meshes are not technically terrain

[snow hare]

so i experimented with other approaches

[snow hare]

well, it's techincally a mesh with material/shader

but since the game is moddable, skyrim generates lod mesh at runtime somehow

from the cell/chunk data

at least it looks like it does

[winter minnow]

Creation engine is optimized for exactly the kind of distant land it uses
Unity is not optimized for the kind of distant land Creation engine uses

[snow hare]

so that means if i have enough time and knowledge, i can code my own terrain solution

[winter minnow]

That's one of Anikki's suggestions

[snow hare]

Or maybe if there is a different open-world engine avaliable, i should try switching

[snow hare]

well, time to google how

don't you know any point where i can start from

[winter minnow]

There may be Asset Store solutions also

[snow hare]

maybe some popular youtuber

or guys trying the same thing on forums

[winter minnow]

Not at hand

[snow hare]

well, i can't buy stuff from asset store

cuz 🇷🇺

so now i'm just copypasting what i can find or brainstorming myself for weeks

that's how i created plugin support

used reflection to load custom plugins for the game

created simple OnEnable() OnDisable() and EventHandler with custom events

[winter minnow]

I can only say with confidence that the Terrain component is not specialized or particularly good for any purpose

And it's not practical to modify it, if even possible

It's just kinda "there" if you need it for prototyping or something

[snow hare]

You can create custom editor for the component, that's only thing i know

And well, terrain is a sealed class

So you can't extend from it

[snow hare]

Assets like Gaia/WorldCreator/Atlas use own solution, right?

Not unity terrain

[snow hare]

Also if i want my game to be moddable, i need those assets to be included to my devkit, but it's kinda illegal

[winter minnow]

I believe they do

[winter minnow]

Moddability is not my wheelhouse, but sounds like that limits your to your own assets or free assets with permissive license

It's technically possible to negotiate that some part of a proprietary asset be included in your mod tool, likely as a baseline requirement that it can't extracted out for use with other unity projects

[snow hare]

Yeah, might need to use my C999 English level to write some emails xD

[snow hare]

If i create a new instance of a Texture2D to operate with it somewhere, can it have resolution higher than 4k?

[winter minnow]

I think the technical upper limit is 16k

[snow hare]

alr, gives some hopes

[half mason]

Hey guys I've seen a lot of people try to bake collision meshes on a job like here.
https://github.com/Delt06/voxel-terrain/blob/master/Assets/Scripts/Chunks/ColliderGeneration/ChunkMeshColliderGenerator.cs

but the job runs on the main thread. I tried running it on a background thread like this but apparently I can neither bake nor set colliders in a background thread.

private void BakeCollision(Mesh mesh){
Task.Run(() => {
Physics.BakeMesh(mesh.GetInstanceID(), false);
meshCollider.sharedMesh = mesh;
});
}

if that's the case, what's the benefit of doing it on a job? And is there any workaround to bake the data on a background thread?

[chrome mango]

the job will run on the main thread if it's available (work stealing). Physics.BakeMesh is thread-safe, but your other two calls in there are not so it barfs. Have a closer look at the example in the docs

[snow hare]

just noticed another interesting thing

In skyrim CK each chunk is divided in 4 quads(around 16x16), and each quad can have own 6-8(don't remember the exact number) layers

so it's like 10+ layers per cell in total xD

[north oasis]

when i'm painting the terrain, it seems like it's made out of squares, or something like that. look at this screenshot - i tried to paint something with a black texture, and i can't freely draw, because it's very grid-like. what settings do i adjust to make it more free to paint textures, without this grid snapping?

[winter minnow]

You are seeing the invdividual pixels of the control texture

Control texture resolution can be increased, but there are practical limits with how big it can get before it's prohibitively expensive to keep in memory

[north oasis]

how do I change the Control texture resolution? where is the setting for it located?

[winter minnow]

In Terrain... settings, I believe

[north oasis]

ok, thank you

[half mason]

Oh you mean GetInstanceID and changing shared mesh is not thread-safe? Got it thanks.

I though Physics.BakeMesh was giving me the error lol

This works thanks! I put GetInstanceID inside BakeMesh so the callstack was pointing to the same place lol

*AppendGenTask is some locked queue I use for reinserting into the main unity thread

[obsidian cave]

where can i find a terrain generator?

i dont need anything very specific

i just wanna mess around with unity

[half mason]

I'm not very qualified to discuss it, but if you're looking for some static terrain you can create you can go into your scene click create > 3D object > terrain. If you need to create more terrain in runtime(generator), you need to look into terrain generation of which I'm more qualified to discuss.

[obsidian cave]

yes

ill try to create the terrain

[obsidian cave]

you could help me with terrain generation

creating the terrain by myself isnt easy

[half mason]

Do you mean procedural runtime generation or static terrain creation?

[obsidian cave]

static terrain creation

[half mason]

as I said I'm not very qualified for that, you can refer to tutorials on how to do that

[obsidian cave]

how's procedural runtime generation?

generates terrain everytime the game turns on?

[half mason]

Basically, it refers to generating new terrain off noise maps when you run your game. Since these noise maps are functions they're essentially infinite(as long as your calculations maintains precision) and unique. But I don't recommend if you want a simple game/new to unity.

[obsidian cave]

ah

then ill stay away from it

[half mason]

probably work with the terrain editor then

[prime pebble]

A common issue I see with Unity games and water. How do I fix it? The LOD on the mesh looks like it messes everything up

[prime pebble]

In general, the amount of pop in with LODs is really bad. How do I mitigate that?

[solar swan]

Play around with the pixel error value , don’t make coastlines overly shallow.

[prime pebble]

Well what if I did want to make a shallow coastline? After all, it is how a beach looks

I will try pixel error

[solar swan]

You can’t really make very shallow, Denmark style beaches

[prime pebble]

You just can't?

Sounds like a pretty bad limitation

[solar swan]

not if you want to use a generic LOD system that aims to solve the common situations people want to use terrain for.

[prime pebble]

Hmm, okay

[solar swan]

shallow beaches. Actually any beaches are commonly ignored or masked in games because making believable shorelines is a yet unsolved problem

[winter minnow]

A workaround might be to include the shoreline also in the textures (including smoothness maps) of your terrain so the only threshold you see might not be the low quality mesh intersection

[solar swan]

you will find that all games have really bad beaches, except those who are only about beaches and don’t use standard tools

[prime pebble]

Pixel error of 1 looks much better

Why is it not like this usually?

[solar swan]

It removes the LOD

[prime pebble]

This doesn't seem so bad for performance

[solar swan]

Empty scenes never seem bad. It will add up.

[prime pebble]

we will see

[bold blade]

Still kind of new to this unity thing. I'm playing around with perlin noise and procedural gen. I just figured out how to create a smooth gradient from the top of my terraces to my valleys. ( first picture ). I'm aiming for an effect like the age of empires 2 map. The difference between mine and the AOE2 map is that the AOE2 map has squared tiles in a grid like system, but mine has multiple triangles. I'm not really sure what i should be googling to start resolving this.

[opaque rover]

So, I'm guessing having a giant UV mapped, textured mesh as a terrain would be a terrible idea

Giant file size, right?

Wait, can't I do it with polybrush on an unmapped mesh? It does splatmaps afaik

[dawn pond]

i need help with procedual generating rooms if anyone could help that would be amazing

[solar swan]

You can’t do AOE2, SimCity2000, TransportTycoon style elevation with a unity terrain because you can’t arbitrarily flip the triangles. Which will always leave some corners and diagonals in a jagged shape. You can only use unity terrain for terrain shapes that are smooth over multiple grid cells. If you really want that look, you need to make the terrain mesh yourself (procedurally).

[solar swan]

Correct. You typically use tiled texturing blended via splatmaps. With a custom shader you can modify that base texturing with additional global textures, for example to override tint or smoothness.

[bold blade]

I am making the mesh. Perhaps i need to adjust the number of vertices and triangles?

    ```private void CreateShape()
    {
        int width = TerrainSettings.width;
        int height = TerrainSettings.height;
        float[,] heightMap = HeightMapGenerator.GenerateHeights(TerrainSettings);

        vertices = new Vector3[(width + 1) * (height + 1)];
        uvs = new Vector2[vertices.Length];

        for (int i = 0, z = 0; z <= height; z++)
        {
            for (int x = 0; x <= width; x++)
            {
                float y = heightMap[x, z] * TerrainSettings.heightMultiplier;
                vertices[i] = new Vector3(x, y, z);
                uvs[i] = new Vector2((float)x / width, (float)z / height); // Adjust UV coordinates here
                i++;
            }
        }

        triangles = new int[width * height * 6];
        int vert = 0;
        int tris = 0;
        for (int z = 0; z < height; z++)
        {
            for (int x = 0; x < width; x++)
            {
                triangles[tris + 0] = vert + 0;
                triangles[tris + 1] = vert + width + 1;
                triangles[tris + 2] = vert + 1;
                triangles[tris + 3] = vert + 1;
                triangles[tris + 4] = vert + width + 1;
                triangles[tris + 5] = vert + width + 2;

                vert++;
                tris += 6;
            }
            vert++;
        }
    }```

[ionic ember]

oh help, I lost my map and the polybrush or probuilder textures are pink 😥 (it happened when I was looking for a bug in the package and manually deleted some of them from the manifest.json file, but I already reinstalled them again)****
#💻┃unity-talk message

[glacial coyote]

reimport the textures.

[ionic ember]

I managed to recover some textures, but I lost my terrain data, since it was located in a folder of a plugin that I had deleted. No problem, I was thinking of creating another land

[split sedge]

I'm working on a project with the goal of procedurally generating a huge low-poly cave system, and I'm thinking of using Constructive Solid Geometry, but I'm not sure how to approach it. Are there any examples of procedural generation in CSG that I could examine? I believe Deep Rock Galactic has CSG caves, but their stuff is proprietary so I don't really know how it works

[vapid slate]

how can we get custom brushes in this toolbox?

Check out Sebastian Lague on Youtube, he has some great videos on terrain and cave generation

[rancid nimbus]

I feel like I absolutely ungodly suck at creating terrain
how do I learn to make it look good?

I m making a game inspired by muck

[half mason]

Make the texture more detailed and/or smaller

[half mason]

You should always try to use triangles. The GPU can take in quads, but they are secretly converted to triangles for rendering(because triangles define a surface). If you proceed to use quads, you have less control on where specifically the GPU decides to split your quad into triangles, so I recommend you stick to triangles.

For 2D terrain, lock your vertex positions to grid coordinates on a 2D plane. For a grid of N^2 quads you need (N+1)^2 vertices. You can define a lookup table for these vertices. Then for each quad you just need to create two triangles. I highly recommend parallelizing mesh generation, either in a compute shader/unity job. With this your geometry will be limited to a 2D squares. You can define a custom shader to display just the square wireframe.

[thin hearth]

Here's one of the techniques I developed for a hilly landscape. First I raise the terrain:

Then randomly flatten some parts of it

Use the slope filter to paint a cliff texture

Add a bit of random noise

Add some trees, water.

Then add various grass and shrub detail meshes where the grass texture is (don't have a screenshot of this, sorry).

Variation with trees. Bushes.

Rocks

Beyond this, you can study rules of landscape photography to improve your composition. Colour theory for improving your textures and how they work together.

[tulip cobalt]

can someone explain to me why there is still some part of the terrain still got rendered although its not in the game view?

[thin hearth]

Are the buildings static occluders? It seems like it's only performing view frustum culling on the terrain.

[tulip cobalt]

yeah, all of them are statics and occluders and occludee are both true

just re-bake occlusion, got different result but some of the further terrain still got rendered

[rotund forum]

i have a big ass terrain i worked on for quite a while already and performance is taking a dip. 5x5 km made from a 4k map. will it improve performance if i use something like terra slicer to make them into smaller chunks? ive read it helps but i want to reconfirm before i spend money

[solar swan]

slicing it up will not improve performance, all terrains are still loaded, queried and rendered. Can you show a screenshot of what you're dealing with? is it render performance or editor/cpu performance? One 4k terrain should still be fairly usable priovided all other settings are reasonable. You get the best experience with unity terrains if you use a 1k terrain with a 2k heightmap (amortized over quality, runtime performance and workflow concerns). To realize a large world you may need to implement your own streaming world system with small world chunks or somehow coerce the existing unity system to just load nearby chunks (64-512 units in size) and eliminate all init calls (start/enable/awake) on objects that live in these chunks to work around frame-drops on activation of these. Both approaches are equally non-trivial.

[rotund forum]

this is inside a buid and my cpu is 100%ed

though only like the first row of bamboo is a proper 3d object, everything behind is just a quad with billboard shader

the only way i could explain that is if the billboard shader takes the cpu to calculate

[solar swan]

you are rendering too many terrain details for the builtin shader/renderer to handle performantly

see what dialing down the grass density and distance does

[rotund forum]

the grass is not that big of an issue, the bamboo is, and if i dial it down it looks barren and ugly

[solar swan]

thats just how it is unless you invest (a lot of) time in a custom renderer or buy an (expensive) renderer asset

[rotund forum]

so something like the nature renderer in the asset store would mitigate that problem?

[solar swan]

there are ofc art/design tricks you can use, to skip all that but you'd have to figure those out yourself, it seems your world is relatively open, and that will always be problematic. The key to good performance in large worlds is actually by aggressively limiting view distance by designing all locations to be bounded by large objects (mountains/walls) that obstruct long-distance views.

[solar swan]

yes

[solar swan]

though you should rather get Foliage Renderer (less abusive business model, better community, better support)

[rotund forum]

ok, reading the store page, it only replaces the tree and detail rendering so will it work in conjunction with microsplat?

[solar swan]

yes, its made to cooperate with Microsplat, if you also get FoliageRenderer Deluxe Shader and Better Lit Shader you get a very well integrated rendering solution where you can perfectly match up and blend everything (they share many options and features). Alternatively The Vegetation Engine (foliage shader and asset conforming tool) can be very helpful if you are sourcing assets from various places that don't quite match up.

[royal wharf]

Hey, so I am following Sebastian Lague's procedural landmass generation videos and I am at E16 at 8:22, where we are working on colour shaders, and I have done the same things and wrote the same code as him but in the video his map, is black and white where mine is just pink. Anyone who has seen his video or just know a fix to it?

[solar swan]

does your shader have a compile error? are you on the same render pipeline + version as the video?

[royal wharf]

Nope, and nope and nope. I just saw in the comments that The shader method does not work with urp, and that i need to use the shader graph system instead of a standard surface shader

[half mason]

Oh u were using urp? I highly recommend learning how to write unlit urp shaders. You get a good idea on how shaders work

[royal wharf]

Yea, I just chose something in the unity hub. I have never touched shaders or URP og anything like that 😅

[half mason]

I think one of the main reasons anyone chooses URP over built-in is the SRP. It's a very useful tool that allows you to inject your own code into the render pipeline

[solar swan]

Main reason is portability. It runs anywhere. SRP just means you can progressively turn it into HDRP if you have money for assets/hiring to spare and don’t need the portability.

[rotund forum]

fr this is a live saver, thx so much. money well spent

[sleek notch]

Does anyone know why my terrain is transparent ish?

[zenith halo]

if i was working in 3D and i was making a building, and i was exporting from blender to unity, would it be best to build the entire thing in one blender file to send over to unity, or if i separately made each floor in blender to work on them in unity?

[untold basin]

anyone know to to fix

[static sparrow]

When i edit one terrain, all the others get affected, such as if i raise an area in one terrain, all of them get raised in the same area. How do i fix?

[hollow timber]

how do you increase the lod distance of a terrain? It seems to be dynamically adjusting the LOD's, can't figure out what setting does it

[solar swan]

It’s called ‘Pixel error’

[hollow timber]

omg ty!

[cursive basalt]

Im having trouble locating the view menu in 2021.3.40f1

Im trying to add terrain tab to my toolbar

Im trying to convert a plane into terrain

But cant do so if i dont have the terrain box

I am not trying to spawn in a new terrain, im trying to edit my toolbar to get rid of doctrina and replace it with the terrain tab following this

[cursive basalt]

And this tutorial from youtube

[cursive basalt]

Im missing the 3rd step terrain box on my toolbar

[cursive basalt]

It was the dingus video uploaders fault

This whole time

He renamed it from "object2terrain.cs"

To object2terrain.cs**.txt**

[rotund forum]

is there a way to limit the rotation of painted details? i want to paint sunflowers and they should all look in the same direction

[rotund forum]

i also have this hard edge when detail painting where i cant paint into and idk why. does someone know how to fix that?

[pliant bough]

It sounds like you duplicated the terrain. You need to create each terrain separately

If you duplicate it, the duplicates use the same terrain data as the original.

[static sparrow]

Thx

[rocky folio]

Hi, how can i achieve this kinda look with unity terrain?
The 2nd pic is a bit of manual triangulation to flatten the diagonals

[rocky folio]

Basically like this. It looks like terrain, but i wanna get that kinda predictable diagonal ramps

[winter minnow]

Aside from posterizing your heightmap to explicit steps of height there's no official way to do this

However, if your height texture has too low bit depth, or your terrain runs out of vertical accuracy, you will get that type of effect as a symptom

The simplest way to achieve it would be to have a very big Terrain Height and then painting anything on it normally
But that's a bit hacky

[marble sky]

i downloaded a procedural terrain painter and there should be a terrain painter script which i dont have

what do i do

[glad basin]

Hello everyone. I'm looking for the best way to make realistic looking desert terrain. This is where I'm at so far (dislike). I looked at MicroSplat based on reading previous comments in this channel, but it looks like it's only free for the basic rendering system and not for URP and HDRP. I am using URP, so I'm wondering if there are techniques to get some realism or where I should start looking if I want to make improvements for free

I'm not opposed to spending money completely, but I kind of don't like the whole 'Freemium' model where it's like "Buy this upgrade pack, and this one, and this one..."

So if there is one solution that stands out as having great bang-for-your-buck I'd be interested in that also

[solar swan]

Microsplat won’t automagically enable you to make a desert. Find nice textures and paint them on a suitably sculpted terrain is all you need.

[glad basin]

I'd actually prefer a solution that doesn't so I can learn on a lower level how things like shaders and textures and heightmaps are working

I'm just not even sure.... like I saw a video that said to get textures with a blue channel(?) and then use them to paint, but you can only do 4 layers on URP so it isn't a good solution or something

[solar swan]

Microsplat is certainly worth the money, but it’s not helping with lack of art skills

[glad basin]

Not sure why you're pressing that angle...

This is the first time I've used unity for attempting anything serious

I understand there is a learning curve

I'm a professional Python developer at my 9-5

I'm not expecting instant results

[solar swan]

well you’re not making it entirely clear what your problem is

[glad basin]

Ah. I'm basically just looking for someone to point me in the right direction. Right now the texture is all tiled which I think looks obviously silly, it doesn't have any height to it, it's all basically uniform

I'd like to move more toward the direction of realism

As a beginner to Unity I'm not sure exactly where to start

[solar swan]

well, that’s very difficult without advanced knowledge in shader programming or spending on assets. But you technically don’t need to spend any money to make a pretty desert. But realism is just not quite approachable just with builtin tools.

Depends ofc on what you mean by realism

a great texture set goes a long way

for modeling the heightmap you probably need some desert stamps or a tool like gaea or world creator

[glad basin]

https://www.youtube.com/watch?v=-KrTYnCApC0&list=LL&index=2 I did watch this video and it was an interesting technique, but in the comments the author said it only allows for 4 layers on URP and kind of suggested not to do it. Is that a sentiment you'd share (if you're familiar with his technique)? The terrain is going to be integral to my gameplay so I don't want to do a lot of work on it and then find out in 3 months that it won't work due to some unforeseen limitation

[solar swan]

My sentiment is to not deal with this limitation and use Microsplat. I find a generic recommendation on not using height blending because of 4-layer-limit silly.

[glad basin]

Ok. I've seen you recommend MicroSplat before. Is that the one you're most familiar with or is it better than others like Gaea or World Creator?

[solar swan]

The unity terrain renderer/shader is quite inefficient and severely lacking in features.

[glad basin]

Yeah I'm starting to notice that lol

[solar swan]

Those other two are external tools. They do something entirely different

[glad basin]

Ohhh I see

[solar swan]

Microsplat is a shader

It does nothing for you without textures and a great heightmap and well painted splats

[glad basin]

Hmmm. Ok, so this is a good start for me. I'll avoid trying to do things completely in the basic terrain creation tools

I'll have to do some research into how these other things work

[solar swan]

To get that heightmap and potentially the splat maps you use gaea/world creator or paint with stamps

[glad basin]

Oh interesting

[solar swan]

For textures you can use quixel megascans and other such repositories or make your own with substance/zbrush/3dcoat/photogrammetry and similar tools

[glad basin]

Nice! Tyvm for that info. I'll look into all of these things. Definitely was feeling that "hitting a wall" feeling from not knowing how to work with this terrain

[rocky folio]

Export, edit posterize, re-import heightmap is a way to do it yes. But is there a way to directly do this in unity via script?
Make a button and do p = Mathf.Ceil(p * stepSize) for every pixel? This is to avoid converting to external tool in the workflow
Sry just asking here bcoz don't have unity until next week..

[soft tartan]

hi so i just duplicated a terrain but when i place trees on 1 terrain it copies to the other which i dont want

i want 2 terrains with the same heights and stuff but cant copy it so what do i do

[winter minnow]

If you find some method to do it directly to height data, that could be convenient as it'd save you doing the export and import steps
Otherwise it doesn't make a practical difference if you posterize in Unity or in some other program if you have to re-import the height map anyway
Still, could try stretching the depth very thin, with a large height or otherwise, that way the effect would be fully real time

[solar swan]

You can duplicate the terrain data object and assign the duplicate to a new terrain. You need to enable debug mode in the inspector panel to be able to do this

[lost sundial]

how does built in terrain handle trees? using Graphics.DrawMesh?

[glacial bramble]

dos anybody know why when i build out my game, my terrain textures are all shiny but not in the editor ?

[rocky folio]

Hi, what do u mean by depth, and large height? U mean the max height?

[thin hearth]

I’ve heard claims that it’s instanced rendering but given the amount of draw calls the system produces I don’t think that’s true…

[glacial bramble]

pls if any body knows how to fix this problem HELP, when i build-out my game my terrain dos this to the textures they become all lite or spec Anybody know why, did not use to happen when i used older version of unity like 2021 all was fine i updated to unity 2022 and this happens ?

[pliant bough]

Try switching your color space

[glacial bramble]

i get that but what if i like my game to be in linear space, like i explained unity version 2021 my build out game did not do this, only started to happen when i updated to new version 2022 so what dos that change have to do with anything i don't understand your help here 😀 no offence but dos not make any sense i need my game to be linear space it worked in unity 2021 on linear space so why not now in 2022 its just ode to me ?

[pliant bough]

Honestly I thought you needed to switch to linear. If that's not it, I don't know what is causing the issue.

[glacial bramble]

NP ty for trying

[sterile carbon]

Hey all,
It is better to add grasses and trees to the terrain as a gameObject or by Paint Trees and Paint Details ?

Also if it is better by Paint tools on Terrain, it is better to paint grasses by Paint Details or Paint Trees ?

And what do you think about using Foliage Renderer ?

I'm asking performance-wise

[desert rock]

Paint trees and details

for grass use paint details

performance depends on how well optimized the assets are, LOD's and terrain settings

[sterile carbon]

As far as I noticed, Unity Terrain is not good that much specially on mobile devices and WebGL. So I've started to use MicroSplat instead. Is it right ? So my question about performance is more something general.

About paint details vs paint trees for grasses. I want to use grass mesh, so it is better to use it with paint details or use it with paint trees but with LOD (As far as I know if it has LOD it can't be use in paint details) ?

[desert rock]

I dont use 3rd party stuff so i cant say anything on microsplat. But generaly you would want grass to be painted with terrain details

paint details had its own built in LOD like system

i think they are called patches or something

for low end devices you can simply decrease the grass density and disable shadows

this guy has a great video on it: https://www.youtube.com/watch?v=E4qE-Tc4u9M&t=175s

is using HDRP but should also apply to URP

[sterile carbon]

Thanks

Also which one is better ? Grasses and trees work with terrain wind system or with custom shader ?

[desert rock]

wdym which one?

also idk about the wind, i havent used it

but it should work

[sterile carbon]

I'm talking about terrain wind vs shader wind

[desert rock]

whichever one works

there is no better

[sterile carbon]

Sorry for asking too many question.
Is it possible to remove some part of the terrain ? I already have a terrain which was created before but it is too big and almost 0.75 of the terrain is empty and I don't want to have those empty areas.

[sterile carbon]

Or if I can export terrain data and reimport on smaller terrain ?

[quasi dragon]

Hi! I am trying to paint trees on terrain but the leaves don't show up. The tree is a prefab and the leaves are a child in this prefab. When I manually add the tree to the scene, the leaves do show up

[last cliff]

Hi I'm trying to paint texture onto the terrain but it's not working, I am able to raise and lower the terrain, i can also paint trees, but not textures? Any ideas?

[desert rock]

you can use the paint holes tool to remove that part

[desert rock]

show your terrain layer settings

[last cliff]

Didn't realise i had to change the shader from standard to texture, terrain, nature...

[desert rock]

nvm i guess

[foggy jacinth]

am i understanding this correctly.. Pen Pressure still does not work with Terrain? or perhaps i missed a toggle somewhere

[shell geyser]

Hey folks. Does anyone know of a guide or tutorial for manually setting up adjacent scenes with their own terrains and managing seamless edge-line ups? I've been experimenting with Gaia Pro (which does this in its own way), but really need the ability to runtime deform terrain and cull trees/grass without resorting to making them game objects. Gaia implements its own terrain which prevents much of this. So I was thinking of moving to using Microverse and Worldstreamer, and the admittedly less performant Unity Terrains. But plenty of examples exist for deforming that at runtime. Just from a high level what workflows have worked well for devs! Thanks.

[solar swan]

Just so you know, microverse is not a runtime tool

[shell geyser]

Oh I know, its more that by using Unity terrains I can get access to the underlying terrain / trees and grass, and modify them using my own tools.

[signal steppe]

why when i place tree on my terrain they are small and dont have leaves ?

[jaunty nimbus]

hey, not sure if this is where I go to ask this so apologies in advance, but how would I go about making a cave similar to little lamplight, I know bridges and lights would be made in blender, but how would I go about making the cave itself?

[winter minnow]

External meshes, same as the bridges and lights

Unity's Terrain can't do caves

[signal steppe]

someone pls

[winter minnow]

If I had to guess maybe the leaves have a material not supported by terrain, or the leaves are a separate object

The detail prefab must have only one mesh

[signal steppe]

ok and why they are small ?

[winter minnow]

I expect your tree mesh was imported with a scaled transform, or got one in the conversion process which is a very common mesh export problem

[jaunty nimbus]

Sorry. I was asleep thank you

[signal steppe]

so if i change the scale of my prefab my tree will be at the right size ?

[tidal dove]

Hello everyone

[winter minnow]

Probably not
As far as I know terrain details ignore the scale of the prefab, which could be why you're having the scale issue in the first place

[signal steppe]

so what i have to do ???

[winter minnow]

First check if the mesh prefab has non 1 scale, or if it shrinks when you reset the scale to 1
If it does, apply a scale modifier in its import settings to negate it, or re-export it with proper units so there is no scale
Also check if the leaves are a different object

[signal steppe]

ok so i change the scale on blender and i export again thats it ?

[winter minnow]

Preferably you'd export with the correct units so there's no need to tweak the scale
That's only assuming your prefab has a weird scale and this is a unit conversion problem
Scale chapter here: https://polynook.com/learn/how-to-export-models-from-blender-to-unity

[signal steppe]

i finally did it but my tree are in the ground now 😦

[winter minnow]

The object origin is in the wrong place

[signal steppe]

how can i change his place ?

[winter minnow]

There's many ways to do that, but it seems you should first look into what an object origin is so you can understand what to do

[signal steppe]

but if my object origin is not my leaves i cant put material on my tree

[winter minnow]

That doesn't make any sense

[signal steppe]

its my only tree who do this to me 😦

[winter minnow]

That doesn't have anything to do with object origins

[signal steppe]

its me again so i have mass place my trees but how can i random y rotation of my trees and what can i do for this 👇

[winter minnow]

the editor tells you in this screenshot what's the issue with rotation is

[winter minnow]

If by "this" you mean the disappearing trees, it's tree/detail distance in your terrain settings that controls it

Terrain attempts to swap them to billboard impostors, but as the UI tells you that's not possible without a compatible shader

[signal steppe]

ty

[signal steppe]

i dont understand what i have to do with this for use the random rotate

[winter minnow]

You need to look up what LOD groups are in Unity and how to add them in

[signal steppe]

ok

[signal steppe]

i have placed detail mesh but my box colliders dont works 😦

[winter minnow]

Terrain details are meant for grass and foliage and do not support colliders

[solar swan]

you need to place these rocks as trees

[signal steppe]

oh ok

[signal steppe]

why my meshs appears when they are near but my tree appears when they are far ???

[proper sparrow]

Sorry idk where else to ask this

[winter minnow]

RectTransform is the 2D counterpart of the Transform component
It doesn't really make sense to use it for objects that are not UI

The Pivot of 3D objects is always the Transform position, unless a specific component allows you to modify it (like collider components do)

If you want your mesh to be at an offset, make it a child object and move its transform relative to the parent transform

Or use a mesh that has the pivot baked into its geometry

[proper sparrow]

Thank you ❤️

[signal steppe]

someone pls ?

[livid bobcat]

Do trees just not work in URP? The shader doesnt work at all, its just magenta

Speedtree7 seems to render but im not sure if this is the correct solution, and if it is why does the error give an incorrect solution

[solar swan]

Use the URP shaders. Synty assets should supply a package with materials for all RP

[livid bobcat]

I don't remember seeing a URP material folder, I can check again I guess

[solar swan]

Normally there would be a unitypackage that you have to unpack

In any case, you can convert them manually

[livid bobcat]

That's not the issue

I've already converted them, the issue is with the tree shader

Speedtree8 shader seems to work but its not what the warning says

[solar swan]

Dude, that’s exactly what I told you earlier

pick the URP shader. If you don’t have it, ask synty for it, they will probably tell you to use the default URP shader.

[livid bobcat]

I'm assuming you're referring to the Standard Lit material for URP

Unless theres a soft occlusion shader available in URP that i dont know about

URP/Lit doesn't work for terrain trees

if i try to use URP/Lit it gives me the error "couldn't be instanced because bounds could not be determined"

Then if i get rid of the LOD group i get the error "The tree X must use the Nature/Soft Occlusion shader"

the problem is the Soft Occlusion shader doesn't work in URP

or at least I couldn't get it to work

anyway speedtree seems to work so im just going to use that

[signal steppe]

someone pls ?

[smoky wren]

hi chat, how to draw texture on terrain without blending?

[winter minnow]

Blending is built into the terrain shader, so generally you don't
The next best thing would be to use decals or meshes, but it depends on the situation

[smoky wren]

i need to draw a trail but it has a bit blurred edges

and looks like made of pixels

[winter minnow]

If you're using terrain painting, it is
The splatmap is a texture and it has to be fairly low resolution if your terrain is big

By splatmap I mean control texture

[smoky wren]

i mean the trail is a bit curved and it looks pixelated

[winter minnow]

Yea

[smoky wren]

i can't fix it right?

[winter minnow]

You can't just with terrain painting

[smoky wren]

ok, thanks

[neat iris]

Which color theme do you like better? A or B? 🤔

[smoky wren]

i think B

how to fix my trees overlapping with each other? i need to place lot's of trees (to get forest)

i have a question, is that possible to fix those shadows on the grass prefab?

[signal steppe]

someone know how i can fix my problem ?

[humble veldt]

maybe you have differrent distance of visuallisation

[humble veldt]

chek it here

[solar swan]

Make your vertex normals on the grass mesh point towards 0,1,0 in object space. Add some noise to this direction to make it look more puffy. Use a grass renderer that can align grass instances with the terrain normal.

[fervent ridge]

nvm fixed it

Can somebody tell me how to fix this error when applying splatmap to unity terrain? I am using splat node from Gaea to create a RGBA png.

[wise surge]

Anyone know how can I paint or place grass on mesh terrain for Android, or what tool is good for Android?

[thorny swift]

Hi, try assigning those TerrainLayers to terrain first and then copying splatmap. Toolbox just copies to a Unity Terrain SplatMap array which in this case is empty as your terrain does not contain single TerrainLayer (visible by default checkerboard texture on terrain)

[proud forum]

Thank you, will try.

[proud forum]

it worked

[silk berry]

How do I get rid of this werid shine? I changed it to greyscale yet it still looks like that

[winter minnow]

If you're using Terrain, the terrain layers let you specify a smoothness

Texture import settings would not have anything to do with it

[signal steppe]

I dont find

[silk berry]

It's on the lowest smoothness though

[winter minnow]

Can you triple check that it really is
Your terrain layers can be seen having different smoothnesses

[silk berry]

all on 0.

[winter minnow]

What's cropped out above those sliders

Actually I'd rather see the terrain layer settings from the terrain editor

Since it may have properties the asset doesn't show

[silk berry]

Not sure where terrain layer settings is located but I found layer properties which doesnt have anything

[winter minnow]

It has nothing even if you select a layer?

What render pipeline and unity version are you using by the way

[silk berry]

Oh! Mb forgot to select a layer lol. Here:

[silk berry]

URP and unity 2022.3.40F

[winter minnow]

I think since you put Alpha Source to greyscale that gave your texture an alpha channel, which is then used as smoothness
If you hover over Opacity as Density it tells you that without that alpha will be used as smoothness

In this case I'd set Alpha Source to import texture alpha (so that it's pure white or not imported at all), enable Opacity as Density and then tweak Channel Default Values field you see there

[silk berry]

I changed a few settings like I changed the textures to Input Texture Alpha but I now get a plastic kind of look.

[winter minnow]

"A few settings"? Did you do the three steps I asked

[silk berry]

oh yeah and also turned on Opacity as density and tried to adjust some of the Layers Values

[winter minnow]

I don't know what's happening in your end, but if Opacity as Density is not checked and the material has data in the alpha channel, that alpha will be used as smoothness
Otherwise the sliders will be used

[silk berry]

hmm werid

thanks for your help anyways. Didn't know about the layer settings!

EDIT: I found that when swithing from building anddroid to Windows it fixed it

[winter minnow]

Seems a bit nonsensical to me, it's not like android is restricted to plasticy terrains
It's possible an editor restart could've helped just as well

[silk berry]

yeah maybe

just saw it on reddit and thought to try it out

people also say switching it to 24 bit RGB helps too

[winter minnow]

24 bit RGB in what context?

[silk berry]

changing the texture import to 24 bit RGB

not sure how but can't be that hard

[winter minnow]

24 bit RGB does not support alpha, so it might coincidentally help by removing the alpha channel
Otherwise there's not technically a relation

[silk berry]

Do you know what it's called or where I can find it?

scrap that I found :D :D

Lets GOOOOOO

Default tab has some generic formats, overrides in the platform tabs have some more specific ones
Still, terrain layer smoothness works just the same regardless of format

[woeful halo]

hi! Need a little help with terrain. i want to make a map from real life. any advise how to make it?

[solar swan]

can you be more specific? general concern with reality based maps: proportions in reality are not usable for games (as in at all).

[woeful halo]

I want to make a map that looks like the real life place. Thats all. I just dont know how

[signal steppe]

i have made a script when i touch my tree he burn and become black but i have placed my trees on terrain and it dont seem to work someone know why ???

        {
            col.gameObject.GetComponent<Material>().color = Color.black;
            firePrefab = Instantiate(fireObject);
            firePrefab.transform.position = col.gameObject.transform.position + new Vector3(0f, 1.5f, 0f);
            firePrefab.transform.localScale = col.gameObject.transform.localScale * 1.5f;
        }```

[humble veldt]

Have you placed your trees with terrain tool ? Or placed them by yourself ?

@signal steppe

[signal steppe]

massplace

[humble veldt]

Try to drag them by ourself from assets and test if it’s work

[signal steppe]

ok

[humble veldt]

Because i think it’s because you have any game object on the scene with same tag. When you use a mass place it not create any game objects whose script can interact with

[signal steppe]

ok

[gentle musk]

how do I make I more random?

I am a complete begginer on terrain this is my first time using this tool

[signal steppe]

so what can i do my map is big i will really need to place them by myself ???

[mystic topaz]

Most likely yeah, that's what I do in my game at least, I have a scene with like 2k trees handplaced

[signal steppe]

💀

why they just dont make something to fix this problem

[mystic topaz]

there surely is a way but I just didn't find it yet

[signal steppe]

oh ok

[azure veldt]

Hi could I get some help with Terrain textures please? I want to have an effect at runtime that changes a small patch of the texture when a bomb hits, imagine a paintball hits the terrain and splashes

I am curently using decals but its not effective because it doesnt follow the contour of the terrain

[winter minnow]

Doesn't follow contours how exactly? I think decals are known to adapt to their target surfaces

[azure veldt]

thats what I thought too, but no I dig a hole and the decal continues to just lay across the original terrain and doesnt recognise the hole that I have dug

[winter minnow]

"Does not recognize"?

[azure veldt]

Thats not clear? sorry, I make a indentation in the terrain, and expect the decal to follow the contours of the terrain but it does not. It behaves as if there is no indentation and the decal is placed on the terrain as if ther is no indentation.

[winter minnow]

I wonder what that looks like
The one thing decals are supposed to do well is bend to match contours of the surfaces they're placed on

[azure veldt]

yeah its not working as expected, the idea I had was that the terrain deform happens and the decal happens at the same time and the decal hasnt registered the change in the terrain

[winter minnow]

Can you show what it looks like

[azure veldt]

ok it will take a few minutes to set up

also theres another glitch, what I am doing is digging a hole with a pick, and I want the ground to look like its been dug, what happens is the decal leaves an outline of the pick

like when the decal is placed, the pick just happens to be in the scene

give me a minute to set it up

ok Imma drop several images here is that ok?

[azure veldt]

ok tpo spam this channel with several images??

[north oasis]

Hi, do you think it's better to use the built-in Unity terrain creation tool, or rather create it in another model creation software like Blender?

[winter minnow]

If Unity's Terrain does what you need, it's perfectly good

[north oasis]

alright, thanks

[winter minnow]

Those with a need for hardcore optimizations or particular land features may find it lacking

[uneven glen]

Hello guys. I hope someone can help me out

I'm using a tree from the asset store. My project is (unity hdrp versión 2022.3.32f1 lts ). I'm creating a terrain with trees and grass for a cinematic . Everything is ok on the scenes even on the game mod ( the grass and the trees are moving) . When I create the build . Only the grass is moving, the trees 🌴 are static , why ?

[gritty plover]

what is the actual and optimized way to handle Huge terrain for Mobile Games in Unity ??

[solar swan]

There is none. You need to custom build that. Built in terrains cannot be ‚huge‘ (in any practical sense).

[winter minnow]

What "huge" means entirely depends on the game anyway

What optimizations can be done and how they should be done likewise

[winter minnow]

The most common reason why editor and build are different is that they're set to use different quality levels

Although if by "mod" you mean it's a mod to a game, then it's impossible for us to speculate what's wrong

[tulip hamlet]

is there any way to paint details on terrain if the details are sprites?

[solar swan]

Paint the texture in the sprite?

[tulip hamlet]

you misunderstood

basically

u can paint rocks and stuff on terrain

i want to do the same

but im using sprites

[solar swan]

Same answer

[tulip hamlet]

not painting as in painting textures

[solar swan]

the simplest form of terrain detail is a quad with a texture inside it, which is also what a sprite is, by a different name. In terrain they are called billboards

[queen rivet]

yes sprite is terminology that is more likely for 2D games, they don't align with view direction

[smoky wren]

hi guys, how to make cliffs on terrain so player couldn't climb them?

[vale salmon]

how do i place these onto the ground? i am terrible with the tile palette

[cold vine]

It’s probably slicing your image in a way where those ground elements start in the middle. Might have to redraw them

[errant scroll]

Is it possible to make my own trees that can use the unity wind system? Ive so far been unable to work out how?

[rose sentinel]

How do i carve out a shape for a river? All the in built options i cannot see any carve tool only ones that increase the terrains height any fixes?

[solar swan]

There is no builtin tool for making rivers, roads or similar shapes. You can however custom code one with a spline or use an asset.

[rose sentinel]

how i use spline i am a noob

a tunity

i live off mf tutorials 💀

i have no skills

[solar swan]

Then your only option is to buy an asset like microverse.

[rose sentinel]

i have no money

[solar swan]

sorry, this is not a tutorial service 😉

[rose sentinel]

can i sell my kidney or smth

for money

BRO THIS IS RIGGED

[winter minnow]

Any tool that raises and lowers terrain can be used to make a river

There's no difference between "carving" and lowering terrain

But note that the terrain has minimum and maximum height levels, and iirc it starts at minimum

To be able to dig below minimum you have to increase the whole terrain first
There was a button for that functionality somewhere

[prime fossil]

hey, i got this problem in terrain, my trees are white, i got no clue why but if anyone could help me i would appreciate it 😄

im using assetstore assets, also when i change to hdrp all trees are pink 🤔

[jaunty nimbus]

sorry if this isn't the right area, but can anyone suggest a good environment tutorial to make a level in games, preferably from blockout to finish? I am a very visual learner so while I understand the process it would help me understand it more if I saw someone do it

[minor merlin]

It might be due to shader error

You may need to set the shader properties manually

The white issue might also be related with shader error

[prime fossil]

whats shader error

[minor merlin]

Are these trees still white when youre close to them?

[prime fossil]

yup, if im far they arent

[minor merlin]

Then the LOD groups shader might be wrong

[prime fossil]

how i fix it

[minor merlin]

Go to the prefab of your tree

Then select the main obj

Navigate to bottom and youll see there is LOD component

Or just go to the LOD group and set their materials properties

[prime fossil]

and just changing it, that will help?

[minor merlin]

Yes if anything wrong with the material it will

[prime fossil]

do you mean LOD Quality

[minor merlin]

No not the quality

basically when you go close to the tree the selected mesh with material is displayed and in your first selected mesh, your material might be wrong.

[minor merlin]

If you are new these might help you

1.Use Smooth Height tool to make terrain's sharp holes/peak smooth.
2.Use real-life reference.
3.Use Terrain Stamper tool to speed up your project

I love to help people, if you need more help in future let me know.

[prime fossil]

now i missed the idea, im sorry xD

[minor merlin]

Use the tool called "Set Height " and smooth them using Smooth Height tool.

[minor merlin]

No prob

[prime fossil]

did u mean in hdrp 🤔

[minor merlin]

Its for all cases

[prime fossil]

aight, do i have to dpuble clic that asset or just drag that tree on the game and then change in inspector

it looks like this rn, got no clue why it has white colour

[minor merlin]

Is it set to specular?

The material

[prime fossil]

i got no clue xD

@minor merlin

[minor merlin]

can you click on the optimized leaf material

just click the drop down icon

[minor merlin]

try changing the main colour and translucency colour

[prime fossil]

to green?

[minor merlin]

Hmm you can put it to green

whatever fits the best

[prime fossil]

hahaaaa

thx a lot 😄

[minor merlin]

also the translucency colours most probably would be lighter then the main colour

[prime fossil]

i got no clue what translucency color does but main clr helped 😄

[minor merlin]

it might be for subsurfaces scattering

hey make sure your translucency colour is lighter than the main colour

[prime fossil]

aight

[minor merlin]

Thanks have a good day

[prime fossil]

you too 😄

[prime fossil]

one more thing xD

if there is no material what will help then

that trans color didnt help, tried to change

[minor merlin]

Well asset creator messed up. They used their script to control the shader properties. It looks like they didnt provided the main color option

[prime fossil]

haha

i got no clue how but managed to get there material xD

[minor merlin]

Nice

A tip, always mess around youll help your self

[prime fossil]

hahah

this looks weird

donno whats goin on

lol

[minor merlin]

Hey

[minor merlin]

Try closing scene view tab

And add again from window>project>scene view

[prime fossil]

ill try once i get back, thx tho 😄

im working on laptop rn, but when i change to hdrp my terrain just dissappears and trees stays 🤔

and are pink, do you know how i get all textures back xD

@minor merlin

[minor merlin]

Sry late reply. I am not free today ill text you tomorrow. For now i think its due to terrain shader error. You may need to build terrain again or backup the height map of terrain and stamp it.

[prime fossil]

Dw, thx 😁

[minor merlin]

You're welcome

[proud forum]

Hello

I am using Unity terrain in URP. I am using a 2k heightmap and 2k splatmap. I see weird deformations in the terrain. What could be the cause? Has anyone see something similar?

These small deformations are not present in source heightmap.

[minor merlin]

Tho it looks more realistic with small deformation but you can still fix it.
In your height map texture if there is any change in color (black>>red) it will be visible since it deforms the terrain by getting the value from texture.

Solution:
1.You can use Smooth Height tool in Paint Terrain section (Set the blur amount to 70-100)

2.Try fixing the texture by bluring them where the small holes appear.

If i were in this i would choose first one because its easy and takes less time. Hope that helps.

[proud forum]

Thanks for the help. Let me try these.

[prime fossil]

hey, i got a problem with terrain, im tryin to add grass and its not showing up, i donno whats goin on

im using vegetation spawner

[minor merlin]

Check your Lod for grass and your rendering asset.

[prime fossil]

Ill check tmrw, can i dm u then? Or smthn i got no clue what to check there🙊

[minor merlin]

Ok you can

[prime fossil]

Thx

[prime fossil]

Huh?

[minor merlin]

Amm

Sorry but my hand slipped

[prime fossil]

Ah dw 😆

[ember gust]

Hello! I am very new to Unity, I have created a terrain and added a texture to the whole terrain. And now I want to start painting the terrain, but it looks pixelated for some reason when I paint it? The screenshot includes some terrain settings, does anyone have any idea why it looks like this? 😅

[winter minnow]

It looks pixelated because they are pixels you are painting

All terrain painting is limited by your control texture resolution

You could increase it, but your first option is to simply use a softer brush

[minor merlin]

Although, spazi is correct you can also increase Control Texture Resolution.

How to:
Just navigate to bottom of terrain settings and Increase Control Texture Resolution.

Tip:
Since you are increasing the Control Texture Resolution , I would also increase the Height Map Resolution and Base Map Resolution. It will look better.

Note:
After Increasing Resolution, you might not see the difference, you may need to repaint textures.

[minor merlin]

Question:
by the way I was about to ask a question I have made a really big terrain, its about 16 square meters.
the reason I am mentioning the size is, I put a lot of hard work designing the whole terrain and was little away from completing and then i felt needing of the terrain tool package (from unity)
so if i import it will it break my terrain?

[prime fossil]

@minor merlin i sent u a friend request 😄

[minor merlin]

Accepted

[quartz wyvern]

I found a terrain tool called eden painter... is this ok to use or should I just stick with the Terrain tools in the pined posts? Also. I'm brand new to making terrain.

[azure veldt]

HI, I have a terrain question but its in script form, so not sure if it belongs here or in scripting. The following script changes the terrain texture from texture 0 to texture 1 on the press of the spacebar. I want to simplify it so it just changes all terrain texture to texture 1 and nothing more. I appreciate any advice. https://paste.ofcode.org/jhAxPqQszaCDcs8T3txfHQ

[severe pumice]

might be a big ask but how do i generate a noise/height map for an island (it'll be surrounded by water so the player cant escape) and then make the map like that

preferably a new height map every time

so seeds ig

[solar swan]

Use a library like FastNoise and layer a few noise functions on top of each other, multiply that with a radial gradient centered on the middle to make it an island

there are assets on the store that give you a node based ui to define the noises and masks

[swift sage]

I'm making terrain in runtime, but I notice this "artifact", I suppose that means the terrain aren't connected as they should right?

I'm doing this.

    {
        for (int x = 0; x < terrainTiles; x++)
        {
            Vector3 tilePosition = new Vector3(x * tileWorldSize, 0, z * tileWorldSize);
            Terrain terrainTile = CreateTerrainTile(terrains, x, z, tilePosition, terrainHeight, resolutionPerTile, tileWorldSize);
            terrainTile.terrainData.SetDetailResolution(heightMapSize, 16);
            terrainTile.shadowCastingMode = UnityEngine.Rendering.ShadowCastingMode.On;

            // Calculate the portion of the heightmap for this tile
            int startX = x * (resolutionPerTile - 1);
            int startZ = z * (resolutionPerTile - 1);

            ApplyHeightMapToTile(terrainTile, heightMap, gridSize, cellSize, startX, startZ, resolutionPerTile);
            
            terrainGrid[x,z] = terrainTile;
            
            // Come on dude be nice with others! :-\
            terrainTile.allowAutoConnect = true;
            Debug.Log(terrainTile.terrainData.detailPatchCount);
        }
    }

    AlignAllTileBorders(terrainTiles, 5);

    // Connect terrains... again.
    ConnectTerrains(terrains);
}```

AlignAllTileBorders is just used to smoothly align the vertex with the next tile.
Then I run ConnectTerrains

private void ConnectTerrains(Transform terrainParent)
{
    Terrain[] allTerrains = terrainParent.GetComponentsInChildren<Terrain>();

    if (allTerrains.Length > 0)
    {
        for (int i = 0; i < allTerrains.Length; i++)
        {
            Terrain terrain = allTerrains[i];
            Terrain leftTerrain = GetTerrainAt(i - 1, 0);  // Tile a sinistra
            Terrain topTerrain = GetTerrainAt(0, i + 1);   // Tile sopra
            Terrain rightTerrain = GetTerrainAt(i + 1, 0); // Tile a destra
            Terrain bottomTerrain = GetTerrainAt(0, i - 1); // Tile sotto

            terrain.SetNeighbors(leftTerrain, topTerrain, rightTerrain, bottomTerrain);
        }
    }
}

But from the pixture looks like something is wrong and for sure with the texture it will looks ugly 😕

[swift sage]

Anywone?

[swift sage]

please 🙏😅

[minor merlin]

To fix the issue with the visible line between your terrain tiles, here's what you can do

1. Ensure Consistent Heights at Borders
   When generating the heightmap data for each terrain tile, make sure the heights at the edges match exactly with those of the adjacent tiles. This alignment is critical for seamless terrain transitions.

2. Check Alignment Logic in AlignAllTileBorders
   The AlignAllTileBorders method should ensure that the vertices at the borders of adjacent tiles are identical. Double-check this method to ensure it's correctly averaging or copying the height values at the edges.

3. Recalculate Neighboring Heights Manually
   After generating heightmaps, you may need to manually adjust the heights at the borders to match the neighboring tiles. You can iterate over the border vertices and average their heights to ensure they align perfectly.

These steps should help you eliminate the visible line between terrain tiles and create a seamless environment in your game.

[fallow bobcat]

how do i make the terrain not become low polly like this on steep uphills

[solar swan]

Terrain has a constant atomic resolution. If you want more detail you need to increase your overall terrain resolution (wasteful if you don’t need that detail in many places) or represent these tiny hills with meshes.

[fallow bobcat]

Thanks!

[prime fossil]

guyss i'm trying to paint my terrain, but it doesnt let

me paint it

[prime fossil]

nm 😄

[minor merlin]

This happened because your Height Map resolution is low.

Solution:
1.Increase the Height Map resolution.
Navigate to terrain settings in the terrain component. Then scroll down and increase the Height Map resolution.

I've never worked in 3d, been working in unity 2d for a year now, I'm a programmer, have near 0 graphical skills.
How hard is it to build a good looking forest that I can use in a horror game? It needs to look good enough to create a scary vibe. How long would it take to build a forest that is large enough to make a simple hide/search game that takes about 2 hours to complete?

It doesn't have to look extremely realistic, just good enough to make it scary

[thin hearth]

Is it possible to fix that when painting multiple terrains it changes the selection, resetting all the tools?

It doesn't even seem to respect an inspector lock

[minor merlin]

Use Terrain Tool package from package manager (unity registry)

[thin hearth]

This is the terrain tools package

I forked it probably some time last year but this behaviour is handled by the UnityEditor.TerrainTools DLL.

[blissful shard]

Hi. So I am wanting to make a floating island that the player plays on. I have a system in place which does footstep sounds depending on what surface you walk on. How can I do this via a 3D mesh from blender? I tried to get polybrush to work but it just wouldnt do it

[rigid junco]

Which part are you having problems with?

[blissful shard]

Hai. So I want a floating island as the playable area. I want to be able to use terrain so I can paint it. I have a footstep system which detects what surface im on which is why i'd like to use terrain. I just cant figure a way to do it. I've tried poly brush. I've tried mesh to terrain (messes it up) . I've also tried putting a terrain ontop of my floating island fbx which looked terrible. The image is what I'd like

[rigid junco]

I thought PolyBrush is made for this kind of purpose, no? What about it didn't work?

[blissful shard]

I'll show you. Give me a sec

[rigid junco]

One way to do it is to use vertex colors and have a shader that interpolates between textures based on the vertex color. This limits you to 4-5 textures though

[blissful shard]

Any tutorial i wathced literally pull their mesh in then paint away with 0 issues

[marble sentinel]

is your mesh unwrapped and has a material?

[rigid junco]

And is the material supported by polybrush?

[blissful shard]

How would I know if it is/is not?

[rigid junco]

I haven't used it. But I would start by reading the doc https://docs.unity3d.com/Packages/com.unity.polybrush@1.0/manual/modes_texture.html

[blissful shard]

My mesh didnt have a material when i exported it. I added a normal one in unity

[blissful shard]

Ty. Looking at it now. I did look earlier but no harm looking again :p

[marble sentinel]

are you on hdrp or urp?

[blissful shard]

URP

[marble sentinel]

shame. found a thread but its about hdrp :/

[blissful shard]

aaah TY for looking

Even the paint part of polybrush looks way different than every tutorial i see. They have bits where they can add stuff like layers etc.

[rigid junco]

So did you fix the material problem?

[blissful shard]

trying to now

[rigid junco]

Just read the doc carefully and do every step and I'm sure you'll get it to work

[blissful shard]

on it 🙂

I mean. atleast its something

[rigid junco]

What does your mesh look like? Show it in wireframe mode

Looks like there might not be enough vertices to store detail on it

[rigid junco]

Yeah that topology looks horrible

[blissful shard]

:/ I'm new to blender. Thought i did a sick job 😭

[rigid junco]

I mean it would be acceptable if you didn't need vertex colors

You can only paint on vertices, but you only have vertices on the edges

Could try to "grid fill" the top plane instead - I think blender has that

[blissful shard]

Will look now. This is way harder than it has to be :/

[rigid junco]

Delete the top faces and select the top edges

Then hit F3 and search for Grid fill

[blissful shard]

I shall try that now. So close in giving up. So tricky

[blissful shard]

oooh it works. fills the top in with virtices. Will need to sculpt a new one

[haughty basalt]

Hi, everyone. Nice to meet you. I'd like someone to help me in using SpeedTrees.

[minor merlin]

Can you explain you problems

[haughty basalt]

HI, are you there?

[winter minnow]

You'll have to start by describing your issue before you can get someone to commit to it

[severe pumice]

i converted to a android game and this happened

everything is reflective

idk how to fix it

before image

[solar swan]

turn down the smoothness on your material?

[severe pumice]

tried that didnt work

changing metalic didnt work either

[solar swan]

does the material have mask texture?

[severe pumice]

dawg idk tbh

im the definition if winging it

not even materials

i put the albedo as the diffuse

normal map

wasnt sure what to put in the mask

i get my textures like this an put it on a material normally

idk anything about a mask map

im new

[solar swan]

your mask is broken, probably has no alpha channel, which means smoothness is 100%, metalness is 0 (which is correct), and AO is 0 (should be either flat 100% or paired with your texture. you can remove the mask and assign flat values to all channels with the sliders. if that doesn't help, IDK.

[severe pumice]

how can i get a mask

this is my first time using terrain

this only happens when i convert the project to mobile too so idk whats happening

[solar swan]

your normal map also looks wrong, check the import settings, it should be marked as a normal map there

also check if your channel remapping has funky settings

[severe pumice]

what is that

pretty sure the normal map is fine

they normally have issues but i fix them

[rose sentinel]

Hey everyone,

I’m trying to apply a texture to a large surface using one material, but the texture doesn’t adjust properly (stretched or not tiling correctly). How can I make the texture auto-fit the surface?

[gilded rover]

anybody know how to paint a terrain during runtime? Like make a blue stain on the terrain when a blue paint bucket drops

[solar swan]

Your mesh has incorrect normals or is scaled non uniformly. Normals can be auto-fixed to a limited extent with your modeling software (probuilder, blender, etc.) You can also (at reduced render performance due to extra texture samples and math) use a triplanar shader to ignore UVs

[solar swan]

One easy thing you can look into is decals, more difficult and probably too coarse for that example would be runtime splatmap modifications. Those however take some effort to perform efficiently.

[gilded rover]

Thank you Anikki! Ill check out decals, if not i guess i have shell out for the MicroSplat asset from the store

[rose sentinel]

I'll try here, tysm!

[foggy jacinth]

i must be missing something here. I made a terrain, spent time fooling around sculpting it. decided to make a lake by lowering the level (sculpt decrease height), but that stops at the original origin. i try to just move the landscape up in Y, and try again, but it still stops at the original origin. I try to use Terrain Toolbox to shift it, but i see no option to do so, short of making another landscape at a greater height to start with.

[minor merlin]

increase the whole terrain Heights

[foggy jacinth]

With Position? if not with Position, i do not know how to do that..

found it, thanks 🙂

ok, that does not seem to fix it though..

[foggy jacinth]

are we still dependent on things like microsplat for more than four layers?

[pliant bough]

No.

[foggy jacinth]

would you mind expanding on that? perhaps examples of solutions

ok, i decided to RTFM again, and see that i can use more, it just triggers another render pass

[sudden burrow]

any one have just face the problem when click 'Mass Place Trees' but didnt show anything

[foggy jacinth]

is this just not a basic function of Unity yet?
https://www.youtube.com/watch?app=desktop&v=YH1zm-Xm-Do
Height Blended Vertex Painting.

[foggy jacinth]

well, it also disables Height Based Blending, which was my intial question

[winter minnow]

Unclear if you noticed this

https://docs.unity3d.com/Manual/class-TerrainLayer.html
Opacity as Density is a feature available in HDRP and URP. This option becomes available on each Terrain Layer when you disable the Enable Height-based Blend option on the Terrain’s Terrain Lit Material, and when you assign Diffuse and Mask Map Textures to the Terrain Layer.

I don't recall reading anything about extra terrain blending passes disabling any feature of the terrain layers
It could be a bug, or possibly some obscure feature I suppose

[foggy jacinth]

i did notice that, thank you, but i think i do not fully understand it. I figured i'd be hand-painting the splat, and i do not understand if this does a height type of blending to begin with

Shoot! i Literally just read that (about the more than four layers), and now i cannot find it again. I will link when i do

[winter minnow]

If I'm understanding the issue correctly, height based blending means "masking the layer by its height map"
You'll still be painting it manually and it won't have anything to do with the height of the terrain itself, I believe

[foggy jacinth]

Basically, yes.. that is the combination of Vertex Painting, and Height Blending in the above linked video. I may just be going in circles becuase i do not understand that there is a a way already in place to do this (or i am just fundamentally misunderstanding the concept)

[winter minnow]

Vertex painting is a separate thing from the blending that's happening here

Unity's Terrain does support that kind of blending by height map, and when you paint with it you paint on splat map / control texture rather than vertex color

But the result should be the same

[foggy jacinth]

Ok, thank you. are you aware of a video tutorial that shows how to do this? i have been going in so many circles, that i am in need of a video at this point, lest i lose more hair

[winter minnow]

If you already know how to paint some terrain layers, getting the "height blending" effect is simple as assigning a diffuse texture with the height as the alpha, and enabling Opacity as Density

So basically the instructions in my above link

[foggy jacinth]

ok, but then how to i change the height, 'on the fly' i mean, how can i adjust that opacity, by painting in Unity

[winter minnow]

By the brush's softness and opacity

[foggy jacinth]

Ok, thank you. i will go attempt this now

[winter minnow]

@foggy jacinth Previously I just had to tick the box for it to work
Maybe the worst terrain texture to test with but it should show the "height blend" effect in action

[foggy jacinth]

Awesome, thanks. gathering textures now to get a test setup going

[winter minnow]

Also, even without Opacity as Density, height blending is done by alpha channel of the mask map while diffuse alpha is smoothness
The checkbox swaps them around

[foggy jacinth]

Oh, regarding the Height Based Blending being disabled, the message was right in the inspector :/ I was to distracted. @winter minnow

[winter minnow]

That's it then I suppose

Kind of a peculiar limitation

[foggy jacinth]

indeed

Ok, i did not quite get the results i was looking for with that method (but i still think it is just not clicking in my brain. still to used to UE for Terrain techniques), but this looks promising..~~ Polybrush just did this~~

lol, or maybe i just fully tricked myself and this is just standard height blending 😁, yeah, pretty sure it is that. (polybrush is not even compatible with terrains)

[woeful halo]

hey, noob programmer here. May I ask someone for help?
Im trying to make a moon with a sphere. My problem is that there's a line i want to get rid of, but i cant figure it out how. Any advise?

[winter minnow]

The texture is not designed to tile seamlessly
You'll need a new texture, or to learn enough texturing to make it seamless

[woeful halo]

okay, thanks

[foggy jacinth]

Why are you sending me DMs? i do not think we've ever even interacted. make sure to read the #📖┃code-of-conduct

[rose sentinel]

Yes, we never interacted, but I had just said "Hey", if you didn't want to just ignore it, I apologize if that in any way bothered you.

[foggy jacinth]

as mentioned, read the #📖┃code-of-conduct as that is literally against the rules of the server. if you have a Unity question, feel free to ask the rooms here

[foggy jacinth]

I assume this is just Unity be Unity? the Terrain system keeps yelling at me
"Saving has no effect. Your class 'UnityEditor.TerrainTools.NoiseHeightTool' is missing the FilePathAttribute. Use this attribute to specify where to save your ScriptableSingleton.
Only call Save() and use this attribute if you want your state to survive between sessions of Unity.
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)"

It seems to do this for any brush

Why does this not exist anymore?

[desert rock]

it does

it comes with the terrain tools package

[foggy jacinth]

Not that i can find. could you point out where?, thanks

[foggy jacinth]

I checked that last night, and did not see a fill option, but checking again now. thanks @desert rock

yeah, unless i am just missing something, the option is not there for Fill, as it was in earlier version of Unity. I am using 2022.3

[rotund forum]

i have a performance issue i think has something to do with terrain

i use the Nature Renderer package because i have a lot of foliage
i have a grass patch asset which covers approx. 40x40 cm, and i tried painting it with detail paint, however it turned out i could paint 256 squares max which is far from enough, i tried playing the the terrain settings to increase the size of the squares but i couldnt change them.
then in frustration, i painted each individual grassblade as a tree
my game is not that big or compute heavy, i have pretty well optimized LoDs for everything and in the entire scene there maybe exist 7-8 4k textures, 10 2k textures and tops 30 below 1k textures, however it still takes forever to load the game in the build (like 2 minutes) and then takes 30 gb ram

here comes in my question:
could it be, that the poor performance comes from the grass being painted as trees instead of details?
and if so, how can i paint more than 256 squares of detail paint

[rose sentinel]

What would be the best way you would recommend me to create a horror house for my game?

[brisk wolf]

anyone know how i can increase the distance at which i can see a texture at its max detail?

[prime fossil]

anyone knows why i cant see my brush in terrain?

[brisk wolf]

could the size too small?

[prime fossil]

no, its compeletely gone haha

size is 15 and cant find it

[brisk wolf]

15 is super tiny for me

what happens when you change brushes or add a new one?

[prime fossil]

nothing

maybe ill make new scene

and try it in there

[brisk wolf]

i dont think an entire scene has anything to do with it

maybe try duplicating the terrain or creating a new terrain game obj

[prime fossil]

umm.... i cant do that in my other scene eitherr

[brisk wolf]

with a new terrain game obj?

[prime fossil]

well its scene iv made while ago, its ready almost, now when i try to add trees it aint workinf

i can massplace but not with brush

[prime fossil]

what could make this happen?

[brisk wolf]

i was thinking it was maybe a terrain settings issue that i was unaware of

but if it happens on a new terrain then probably not

[prime fossil]

😦

maybe ill restart unity

can this be a bug in unity6

[brisk wolf]

oh ive seen more than id like to admit in unity6 bugs so maybe

[prime fossil]

hahah

[prime fossil]

didnt help either

[prime fossil]

well this is error i get MissingReferenceException: The object of type 'UnityEngine.Material' has been destroyed but you are still trying to access it.
Your script should either check if it is null or you should not destroy the object.

XD

[brisk wolf]

It means you're trying to access something that doesn't exist

[winter minnow]

Or more likely the editor is trying to

[prime fossil]

oh thats wrong one i meant to sent you hah, its bug in terrain tools

ig

Unable to load the icon: 'd_winbtn_mac_close'.
Note that either full project path should be used (with extension) or just the icon name if the icon is located in the following location: 'Assets/Editor Default Resources/Icons/' (without extension, since png is assumed)

this one is right one

[brisk wolf]

Maybe a corrupted icon? 🤷‍♂️

It says it's unable to load the icon but I'm unsure why

[prime fossil]

XD

[prime fossil]

well there i svideo of it

[last viper]

Ay guys i have a problem with my terrain brushes
They are all read only
Changed to another project and also another version but it didnt get fixed

[tight cloud]

When ever i try to use this: https://assetstore.unity.com/packages/3d/environments/lowpoly-environment-nature-free-medieval-fantasy-series-187052 in my urp project it comes through in light pink(The materials have failed or something) and with errors. The most basic fix of Edit->Rendering->Materials->change selected materials to urp doesn't do anything. I have no idea what to do. ps. I am using unity 2022.3.37f1

[shell marsh]

Hello! I've made a Terrain in blender and want to use it as a heightmap in my Unity game. How can i achieve that?

[winter minnow]

You are trying to use the BiRP variants
URP variants are under the folder "SRP"

[winter minnow]

Heightmaps are used to create terrains, not vice versa, unless you intend to export the terrain you made in unity out of unity
But then why would you ask how to use it in unity?

[lofty compass]

can someone help with the grass chunks being so obvious?
like can i not make them like how 2d detail falloff?

[desert rock]

play arround with the detail resolution per patch setting in the terrain component

[lofty compass]

is higher better?

nvm i fixed it thank you

[torpid cloud]

Any idea how I can do this in unity?

[shell marsh]

I want to do this:
Blender Heightmap > Unity Plane with the same hieght

[rigid junco]

Do what exactly? I see some vegetation, volumetric fog and a color filter

[winter minnow]

Terrain lets you import a raw file heightmap

[rotund minnow]

Hi, i placed some tree on a terrain, it's night and i don't know why but i can see them from where i am why?

[torpid cloud]

How do i do that?

[upbeat thorn]

yo

im having problems

it only paints the tree trunks

[winter minnow]

I believe tree and foliage meshes must be only one object, not multiple
Also heed the warnings in your editor about LODs and correct shaders

Terrain is quite particular about how trees must be set up

[upbeat thorn]

is there any way i can merge the package into one

or wait i have an idea
