Blender

[tall marsh]

ok

[rapid crow]

Does unity have as many tools for modeling as blender? if so, where do I find them

[thin ibex]

No, because Unity is not modeling software but Blender is

[rapid crow]

i couldve sworn i saw people modeling on unity

[undone lark]

There's Probuilder which is a block out tool with basic modeling capabilities. There are paid assets in the store which are more elaborate.

But none will compete with an actual modeling program.

[rapid crow]

so i have to import models from blender

[shell jolt]

yes

if you just need a blocky looking models in your game, ProBuilder can do that... but just that.... it was meant for prototyping

trust me, you'll hate using that

[jovial dragon]

Is there a way to "map" a 3d area with a 3d camera and import that area into a unity scene? Like a tutorial for that

[clear heath]

Im having a problem with occlusion not working can anyone help?

its not working on trees to be specific

[loud bramble]

I've seen a lot of megascans in UE5 recently. Seems to be a unity integration too: https://help.quixel.com/hc/en-us/articles/360002558138-User-Guide-Megascans-Plugin-for-Unity

[plush hamlet]

hello,

sometimes my player fall under the terrain (or a simple plan shape that I'm using as a floor).
what is the best way to deal with this ?
wider collider ?
wider floor mesh ?

[winter minnow]

Usually you would use a collision detection method that's more accurate than discrete
but I don't know anything about your use case

[plain jetty]

How do I stop terrain grass/trees from colliding with other objects within the scene?

Do i have to manually paint it or is there an easier way to just mass delete any grass/tree that is colliding with another object?

[royal raptor]

Anyone using Bakery GPU light mapper ?

[quick zinc]

your near clipping plane is not close enough

[quick zinc]

you are welcome!

[tiny sparrow]

I'm having trouble getting the terrain paint brush to work. I'm not allowed to add any material to the current "settings" under terrain. Is there something I'm doing wrong?

[regal rose]

Cool terrain.

Looks like from Snowpiercer cinema

[tiny sparrow]

I appreciate it! But this is just the stock terrain texture. I'm trying to paint grass and rock onto it.

It started as a ball game but then somehow my mind went to trains and now it's a train game

Not sure why I can't paint textures though

[regal rose]

Looks realistically

[tiny sparrow]

Still can't seem to figure out how to paint the terrain

[regal rose]

Ye. The same problem. It is so hard to paint a good terrain. I thought it is easier

[viral brook]

Anyone has some ideas onto why the tutorial (up image) Sand Albedo from Standard Assets is way brighter than the same texture from my project?

[fading knot]

Hey how can I get a single grass mesh for terrain detail mesh without importing big packages

I tried to create one but failed

[regal rose]

I imported grass from MegaScan

[manic fog]

hey i have an issue where in the scene the trees that arent loaded show up as white in the distance in the built application

is there a way to fix that?

hello?

[manic fog]

nevermind i figured it out

[foggy igloo]

Why is my terrain dithered?
And how can I remove it?

[fervent hatch]

I want to use rocks and bushes with LOD in the terrain system, but LOD Group components are not supported by normal details. Is there any problem in performance if I add it as a tree instead?

[rose sentinel]

Why is my terrain looking shiny with URP TerainLit material?

[delicate ravine]

hello
i have bunch of trees prefabs with scripts on them, means i have to place them one buy one, is there is easier way by using terrain tools?

[signal dust]

I finally found a solution to that. Go to the layer settings and set the mask texture to the same as the diffuse one, and then set the smoothness to 0

[shell jolt]

Unity isn't photoshop 🍞 🍴

You must use custom shader

[rose sentinel]

Use brush

[verbal nest]

Hey, currently I've imported a height map texture of a real island and put that in Unity's terrain, and it works perfectly. The only thing is, the ocean is flat... and I don't feel like modelling 25kmx25km ocean myself, so does anyone know how I can import the ocean heightmap as well? I've used websites to get the terrain heightmaps and all, but it didn't work with oceans afaik. Any help is appreciated 🙂

Ive looked everywhere and still can't find any high quality (or at least any quality) ocean height map data

[verbal nest]

I found one, though couldn't make it work properly with the existing terrain

[verbal nest]

Hi again, whenever I try painting a texture, the texture gets painted above the spot where Im trying to paint it, as seen in the image. Can anyone help me fix this because I dont know what's going wrong here

[remote wave]

Hey what tool can i use to build my world in Unity? (With a cartoonish style like Mario Odysee or Yokaa Leely)

[delicate ravine]

Hello , im using terrain paint details to paint grass
my issue if the player place a structure on top of the grass , the grass will stick out from the floor
is it possible to make it not render if there is a structure near it?
or the only fix for this is to make the structure floor high / grass smaller
thank you

[brisk flare]

Are there publicly available tools for sculpting more dynamic maps like those of risk of rain 2 or slime rancher? I've been looking for ways to build environments and I've tried the unity terrain system but it doesn't exactly fit what I'm looking for.

things like this

[errant bluff]

hello

how do i get the grass to have space between them

[delicate ravine]

change the brush opacity

the lower the more space between them

[errant bluff]

Okay thanks

[delicate ravine]

how can i make caves in unity with terrain? what brush can i use?

[vale sentinel]

if you hold f8 and use whatever brush i think that will create holes (at least on my version of unity, you can check shortcut manager to see). i think this is what you want

[delicate ravine]

yeah it creates holes but what i want is something similar to raise/lower terrain but not vertically, horizontally

[vale sentinel]

oh does it not work horizontally too

[shell jolt]

You cant do things like overhangs with unity terrain.. or an actual cave with a hole that we can literally explore the inside of a cave

Make your overhangs/caves in blender... Sometimes i do wonder why they cant do this ootb 🍴

[frozen hearth]

is there a way to change render distance of trees i painted onto terrain? after i paint my trees on, i have to more my camera closer just to se what has been painted

[whole kayak]

Heya, I've made a material with a comp shader to render grass. Then I went to paint it on a terrain and realised you can only paint textures, not materials >.< any idea of how I can go about getting my grass in?

[fading knot]

I was adding the grass mesh but it says renderer component is missing, it already has mesh renderer and mesh filter what should I do?

[weak imp]

anybody know how to unlock flythrough mode?

[pulsar mortar]

Hey all, I'm using HDRP on 2021.3 and my "Edit Grass Texture" option is greyed out. I can't find any settings or anything on google about this. Anyone have any ideas?

[harsh briar]

Is it a mesh though? Shouldn’t it be a sprite renderer since it is a billboard?

[fading knot]

It can be a sprite but there is a mesh layer as well to add

[harsh briar]

Can you send a screenshot of the grass prefab.

[fading knot]

there

[harsh briar]

Ok, I didn’t realise you were trying to add a mesh.

[fading knot]

???

[harsh briar]

Doesn’t matter, why don’t you create a 2D grass texture and use the paint grass option rather than a detail mesh. That would probably also give you better performance.

Maybe you need to use the child of the grass parent. Because that’s what the mesh renderer is attached to.

[fading knot]

yeah that helped thanks

[harsh briar]

Ok nice.

[weak imp]

not sure if this the right chat for this but anybody know how to make objects cast shadows but not visible to the camera?

[rose sentinel]

bruh that looks cool

[fervent crown]

how do i fix this?

[wide mulch]

Hello guys, I was watching some videos about Unity and I got a question. How do you make such custom maps/levels "out of grid" like in the screens? Do you draw them on photoshop and import them as gameObjects ? (but must be consequent size of pngs)

[peak hare]

Is it possible to use the tree brush tool if I'm importing the terrain from blender? If not is there a tool that's equivalent?

[shell jolt]

There are tools for that yeah, such us Polybrush... but it sucks...

Better off making your own tool for scattering, it's not that hard

[sand sentinel]

Hello guys
I have a problem with making holes in the terrain
I create a terrain and draw a west hole and then build android and everything is correct
I install the "Shadergraph" package and get the Android build again without changes, but the hole is no longer created, did you have such a problem? My unity is 2022

[sand sentinel]

My problem is only with the hole in the terrain, which is no longer created

In Editor everything is ok but after Android Build this problem occurs in mobile

If I remove the ShaderGraph, everything will be fine again, can someone take this thread to see if the problem is only for me or for everyone?

[jagged bridge]

is this decal ? or what?

why battlefield terrain so high detail?

[rose sentinel]

That’s a 3d model from the looks of it

You combine terrain and models to make this stuff

[sand sentinel]

Please help me 🙏

[unreal lark]

I'm having a similar problem as @sand sentinel with Unity 2022.1 URP. Haven't tried building anything yet but I can paint holes in the editor and they show fine but as soon as I go into game mode the holes disappear. Anyone know why that would happen?

I am not doing anything with Shadergraph however.

[ancient holly]

is there any way to have a terrain brush that draws in cubes? as in, it would look like a minecraft world, but it wouldn't be procedural

should i set it up like it's procedural but feed it the same perlin noise every time?

[potent crest]

Hi, I was wondering if it was possible to add more vertices to my plane since this is not even close to enough for the texture painting I need

[formal mountain]

Does anyone know what type of terrain a iOS game like rise of kingdoms has

[cloud garnet]

Is it possible to replace a terrain layer by an existing layer? I can only seem to replace it by one not on the terrain yet, or remove it - but it only gets replaced by the first layer.

[ancient flume]

Does anyone know how to detect if a player is standing on terrain grass vs regular terrain?

[winged solstice]

How would i go about making a low poly terrain ? Is there dome specific software or sum?

[icy parcel]

Is there any way to create terrain with heightmap using c# ?

[winter minnow]

Yes, look into "procedural terrain generation"

[icy parcel]

Yes i saw many tutorials about mesh generation etc, but I'm more looking for something using unity's terrain tool, with terrain datas etc...

[wet oriole]

Is there any way to blend models and terrain together to make it smooth? Just putting the model there leaves a nasty crease

Left is the model, right is the terrain

I would also like to make the textures look the same but that seems less likely

They're already the same texture, though I'm not 100% sure why it looks so much better on the model

[grave basalt]

different texture scaling and the normal difference on the location where mesh and terrain meet each other

might be possible with some shader wizzardry
i remember this
https://www.youtube.com/watch?v=cOBApMeeJEc

[wet oriole]

Oh! That seems useful

[unreal lark]

Anyone know what causes these squares in the terrain and how to fix them when using an orthographic camera?

Happens when zoomed in or out and from any angle.

Squares aren't there in perspective view.

Happens in all scenes with various different terrains.

[barren oak]

Yep using the API here https://docs.unity3d.com/ScriptReference/TerrainData.html

[icy parcel]

Thx, I'll check that 👍

[severe elbow]

hi im here again, with another dumb problem,
i tried to sculpt a terrain but my textures are keep getting distorted/being low quality, i cant find the solution

[shy urchin]

https://forum.unity.com/threads/the-secret-to-great-terrain-on-mobile.305899/

[severe elbow]

even with the sample textures, "rocks" turns green

what's going on here

i really dont know

[severe elbow]

ok i got rid of roblox texture resolution, but its still tinted green

[severe elbow]

its not a problem with material

[quaint wyvern]

"roblox texture resolution"

lmfao

i might use this from now on

[balmy bear]

guys this happens in build mode, the 6 slot of the texture paint of the terrain turn black
,any texture

any ideas?

[runic wing]

has anyone ever had an issue where any details you painted onto a terrain (like flowers) no longer could be edited and seemed to disappear from the terrain details list?

the details still are present on the terrains, but it becomes impossible to add or remove those details

ah nevermind, it wasn't the details that I used 🤦‍♂️

[distant vine]

Hey Im creaking a chunking system where each chunk composes of the default unity plane mesh (collider and renderer)
I am passing the mesh data from each chunk into a compute shader that will adjust the y component of each vertex according to a heightmap that I provide my script

The problem that I discorvered is that by modifying the mesh data for one of my chunks affects the mesh data for all.

I looked into it and realized that each imported mesh in unity gets shared across all gameobjects that use it (to save space I assume) but what if I want to have each chunk have its unique mesh data that I can modify?
Would I need to generate a new mesh for each chunk instead?

I am also interested in instancing the chunks but that seems like an easier problem to solve because I can just pass in one plane mesh along with the heightmap data for isnstancing

[rare tulip]

Hello! I had a pretty basic level doubt regarding the Unity Terrain System.
I am trying to add multiple "Detail Objects (Grasses)" in my terrain
The problem I'm facing however is that, in Unity, there seems to be a global Detail Density slider.. which affects ALL detail objects..
Is there no way to choose local density settings for any given grass / detail

[fervent hatch]

Sorry if it's a stupid question, but does RaycastHit.textureCoord in a terrain give the same uv in the splatmap? My goal is to detect the strongest layer for step sounds and particles

[barren oak]

I'm pretty sure RaycastHit.textureCoord always returns Vector2.zero unless the collider is a MeshCollider

As per the documentation: https://docs.unity3d.com/ScriptReference/RaycastHit-textureCoord.html

A Vector2 zero is returned if no mesh collider is present in the GameObject.

[fervent hatch]

thanks

I am also having a bit of trouble adding a 5th texture to my terrain. It creates a second splatmap, but I can't add the texture (it paints black instead)

do I need to do something in order to allow more than 1 splatmap?

[fervent hatch]

Nevermind,, closing and reopening the program did the trick

[hoary ore]

Hi im creating my terrain and have to paint in trees shrubs ect. However it states i cant paint because i dont have a mesh renderer i have inported my models from blender and need help any reasons?

[gloomy zinc]

Try to make prefab of that tree and add render component idk really

[hoary ore]

I tried that already

[radiant token]

I created a custom terrain mesh but its mesh collider doesn't work unless I made it convex but that creates a new problem that the mesh has too little triangles so you float above it. Any solutions for more triangles or not needing the mesh set to convex?

Oh I know my problem, the custom mesh is only one sided which means it cannot create a non convex mesh collider, the solution would probably be to either use a real terrain collider or double the amount of vertices with the others slightly lower to make cubes instead of one sided triangles

[still tendon]

Hello I started to have this error

at line 1853

I tried re-installing my editors and creating new project, the problems seems to be in URP.

[rigid junco]

Hey guys, what's the way to add grass on Terrain in Unity HDRP? I'm confused why is it not still natively supported

[rigid junco]

Should I use some hacky shader or a custom renderer with DrawMesh/DrawMeshInstanced?

[remote sluice]

I'm using HRDP with detail meshes but for some reason they wont show up when I paint them on the terrain. I have no idea where to even begin troubleshooting this one

It doesn't even register anything happened, it doesn't ask me to save the scene

my settings for the prefab and the prefab respectively

also I get this error when dealing with this

[safe stag]

you can select all the assets in the file explorer and drag and drop them into Unity

I was

Just image files, pngs afaik

Because each channel has it's purpose. This one's for terrain

Create a terrain object and apply the heightmap

You've exported it as over a thousand individual heightmaps?

What type of game is this?

Ok, you'll need to do a bit of digging as I'm unfamiliar with large multisection terrains, but you'll want something along the lines of a quadtree

It's not really written anywhere but we can only help those who are willing and able to help themselves. I'm not going to do it for you and I've pointed you in a decent direction. Good luck

You hadn't even heard of a quad tree prior to my bringing it up. You've learnt a new term, go google it

[undone lark]

No one is forcing you to be here. 👋

[remote sluice]

Can I get detail meshes to adhere to the slopes of terrain? Like, its normals

[hoary ore]

Hi ive inported my terrain and i wan to paint trees across my land however it says i do not have a mesh render on my prefab so i added it and it still says i dont have a mesh renderer

[winter minnow]

It has no valid mesh renderer

Mesh renderer also needs a mesh filter, otherwise it's not referencing any mesh

[rigid junco]

How do I use terrain detail in HDRP? Do I need a custom solution?

[quartz echo]

Can I produce something like this using the built-in unity terrain tools? If I can, how would I reproduce the flatshaded style. Im trying to make a beach terrain

[quartz echo]

Or do I have to make the terrain in a 3d program then placed the miscs manually?

[cyan copper]

hello, seeking some advice;

i find it a bit hard to sculpt from top-down "God view" my terrain of tropical islands to be realistic but also sanely navigable, i.e. not too steep / not too shallow etc., just the right rate of incline / hill / valley / level clearing etc.

it would be useful if i could do something like 1) quickly "alt-tab" in & out of First Person controller to test the eye-level view of the terrain, adjust > switch & test > adjust > switch & test etc., maybe even sculpt FROM the first person controller view 2) or if there was some way to snap from top-down view to a preset eye-level view, if Editor had some way to setup viewing positions to quickly switch between?

[sleek yoke]

just have a number of cameras setup that you click and type Ctrl+Shift+F to make your scene view the same as that camera view

[hoary ore]

Hi i have a terrain set up and now i want to paint my details onto it but it isnt placing when i hold down left click

is it because theres no texture on the terrain

[turbid linden]

Hey everyone, I wanted to know how I could paint on only one of those terrains?

[turbid linden]

You might be too far to see them

[cyan copper]

are there more precise terrain sculpting tools around? i find myself struggling with the brushes given, even with the terrain sample assets package installed, i need more fine grain control maybe even on specific edges/vertices adjustments... anything like that available (ideally free) ?

for example trying to sculpt a beach, FPS player can enter & exit the water, it's important for a good precise curve of a transition from ground to underwater, cant be to steep, cant be too shallow, needs to be at the right scale relative to player scale, just can't seem to nail it precisely with the provided brushes...

[hoary ore]

nope

[hoary ore]

in fact i want to paint a texture onto the terrain but i dont see an option any help

[gleaming jetty]

Ayo

question

[gleaming jetty]

If i remember correctly there may be an Asset called something like extended terrain tools or something, not sure tho

Here goes a question: I created a terrain, textured it and put some trees down on it. I want my game to take place at night aswell. Once i crank down the skybox lighting multiplier to something like 0.25 or 0.5, everything goes dark except the painted trees which just remain as they were at "daytime".

Is there some way to get the trees to adapt to lighting other than placing them manually?
Thanks!

[hoary ore]

im painting my trees and there extremely tiny and have no textures

[cyan roost]

You'll likely have to make the model larger, unity terrain isn't very helpful in terms of size

Does anyone know how to join multiple terrain objects into one with terrain tools?

[shell jolt]

When you export your tree models out of 3d software such as Blender, make sure to Apply the transform... and when Imported to Unity, make sure the default scaling is 1

[shell jolt]

If you mean of stitching terrains made by Unity's terrain editor then the feature already there, in the terrain editor...

[cyan roost]

I have no idea where that is, I cannot find that

[steep schooner]

Hello 🙂
I used in the past a program that could create a normal map, height and occlusion map (if i remember correctly) from an image
can't seem to find it again
(it was a small program, maybe github, not photoshop)

[steep schooner]

nvm, i found "AwesomeBump" it does the work

[keen rune]

does anyone here have a like a tutorial asset which has a like a floor and platforms ramps and walls just to test player movement in and like wall running and grappling

[winter minnow]

Try the Starter Assets package

[hoary ore]

ok

what does this setting mean please help me

[hoary ore]

That being nature occlusion

[keen rune]

how do i get that

[winter minnow]

Try google

[quartz echo]

Have you tried using another program for modeling terrain?

I made the models in Blender(You can get the program in steam)

How I made my terrain is by using the sculpt tool on a subdivided plane

I hope it helps @cyan copper

[cyan copper]

@quartz echo thanks, is it possible then to convert an imported mesh as a Unity Terrain?

[quartz echo]

Sadly, no.

I was recreating our landscape

They used the unity terrain tools and it looked bad

[cyan copper]

ye... i guess i'm not the only one....

[cyan copper]

very nice BTW 🤩

[quartz echo]

I can show you what our before landscapes and after

[cyan copper]

i see

very nice graphic style 👌

[sacred island]

Wowwwwww

[polar wadi]

I made my own tileset today for rule tiles but I can't figure out how to get water to appear here instead of grass via rule tile.

I suppose I can't

[hollow mango]

why is the height map resolution not in 2x, but slightly off?

my goal is to try and make the terrain grid fit within the world grid

right now its off

[gaunt anchor]

I'm using built in Tilemapper on unity anyone know why my stuff is clipping into each other and how to space em apart? https://gyazo.com/99853f20d38be374e8732706f9d38e24

[agile fiber]

It is possible to convert a blender landscape to a raw file that can then be imported as heightmap in a unity terrain.
This tutorial worked for me https://www.youtube.com/watch?v=53KAZO0cimw, but it helps to be somewhat familiar with blender already.
However, I found it looked better in my game to import it as a mesh (directly from blender) than to import it as a terrain.

[cyan copper]

@agile fiber i'm not against doing the terrain in blender, just gotta learn how... am already to some extent familiar with terrain shaping & painting in Unity, am hoping it would not be too hard to port that knowledge into blender...

[shell jolt]

exactly what you want https://www.youtube.com/watch?v=6WD3G6A_4jo

in the later version of Blender, exporting heightmaps way way much easier

[shell jolt]

Terrain heightmaps must be power of two + 1 due to how quads need to be consist of two triangles and the height will be based on the amount of vertices of those triangles

due to my limited english, that may just confuse you even more... either way, you can do your own research on this, plenty of explanations on forums etc regarding this matter

[cosmic flare]

just wondering for a 2d pixel game, if my characters are all 32 pixels does the tile set for the map need to be 32 ?

[cyan roost]

this isn't really the right channel for that, but your tileset for your map doesn't have to be the same ppu as your player
it might just look a bit off, thats all

[cosmic flare]

sorry didn't know, but what do you recommend for a 32 pixel character

also what is the right channel

[cyan roost]

i would recommend doing 32x32 for the map if possible

and #🔀┃art-asset-workflow might be a better channel, this ones for unity's 3d terrain tools

[cosmic flare]

i see, thank you

[cosmic flare]

oh alright

[solemn fog]

how do i access the pipeline?

[short idol]

Quick question, which terrain setting controls the detail of the terrain? Im trying to get my terrain to look really blocky/low poly but ive gone through almost every setting and cannot find it

[shell jolt]

lower both height and terrain resolutions, there's a limit still how blocky it would look, and the brushes settings affect that too

[junior gull]

i created a ground in blender but when i import to unity it is missing terrain data

how can i use it as a terrain for NavMeshAgent movement

[shell jolt]

What you want to do is to export the heightmap to Unity. This is totally optional btw

without it, you just do the usual with Navmesh, set the layer mask for walkables, jumpables etc then bake it

[tiny wyvern]

Does unity still have problems with more than 4 textures on a terrain?

[wise aspen]

I didn't know that Unity was working on a road system for the terrain

https://www.youtube.com/watch?v=_ujun4DCLBM

https://docs.unity3d.com/Packages/com.unity.template.test-track@1.0/manual/MiscTools.html

[fading mountain]

Is it possible to put ambient occlusion maps into the terrain tool textures? similar to how you can for normal maps

[hearty marlin]

How do i stop it from going blocky like that whilst trying to paint a path?

[shell jolt]

Play around with the blur radius

you may as well use SmoothHeight brush to make them look smoother

[rigid junco]

You can assign a MaskMap texture to the terrain layer. The green channel is ambient occlusion. (Red = metallic, blue = detail mask, alpha = smoothness)

If I understood correctly what you mean

[fading mountain]

tysm

[weak hinge]

Does anyone know if the 2021.2+ tree/detail rendering in Unity uses GPU instancing indirect or not? (i.e via compute buffers). Trying to tell if something like GPUI asset is necessary anymore

[shell jolt]

No, thats up to the user and quite a broad topic, meaning what kind of shader you're using or whether it supports instancing or not and what keywords used if it's custom shader etc... At this point, you can find lotta resources about this matter on the internet really

Keep in mind that the SRP batcher is always priority in Unity, even when you ticked the gpu-instancing if the shader SRP Batch compatible and SRP enabled in the renderer, it will be SRP Batched, not instanced...

Still mind boggling me to this date why they don't bother to make this toggle-able at least 😵‍💫

or at least to let user to be able to custom set the priority for the srp vs instancing

[weak hinge]

Even for terrain details they would use the SRP batcher? Surely GPU instancing is way faster with that number of items..

[shell jolt]

I personally don't use terrain detail, due to it won't allow me to make my own LOD, the default billboarding of terrain-detail pretty much sucks ass tbh... everything on my terrain are scattered with the tree tool with preserved layer-mask on instantiated tree so I can still have much control over it

Give it at try and profile it, it's quite easy to see if they're being instanced or srp-batched in the frame-debugger

[polar relic]

hello!, not sure if this belongs here but..
I've made a randomly generating map made out of tiles, now the draw calls is too high
do i use dynamic batching or static batching? the tiles are placed and never changed from that point

[delicate ravine]

getting this lines when painting terrain, is the issue from the texture itself?

[quasi pecan]

how do i lower the minimum brush size cause for me it wont go lower than 134

[fervent hatch]

how can I use a mesh collider into a tree using the terrain system? My goal is to identify the wall with a raycast so I can change it's material to a translucent material while player is occluded.

It works perfectly when the tree is a prefab, but once I use the terrain to add the tree, the mesh collider stops working

mesh collider is like this

there is no other collider since I use Navigation.AI to avoid collisions instead of physics.

[rose sentinel]

im prtty dumb if it is a easy fix to this but when making grass how could i extend the distance of seing it cause for me its rlly low ive maxed out detail distance and detail density but its not helping alot

[shell jolt]

Make your grass with tree tool instead and make your own LOD group then set the cull distance mode to whatever you want, yeah you can't use terrain detail with this method and totally fine bcos the bilboarding in terrain detail is suck anyway

[rose sentinel]

ty

[shell jolt]

also note, using terrain detail is still the recommended way 😉

[hybrid jungle]

does hdrp have issues with terrain texture painting

cant get it to work...

[rose sentinel]

👍

[thorny swift]

is there any way to see how Unity is calculating PerPixelLighting on terrain, my custom function leaves this broken lighting at the edge of terrain, cant use multiple terrains because of it

[fervent hatch]

it uses the function UniversalFragmentPBR, which you can find in Lighting.hlsl

[thorny swift]

I get the lighting, but I cannot get the normal map from terrain the correct way

[fervent hatch]

inputData.normalWS = inputData.normalWS * alpha;

that's the normal passed to the function

[thorny swift]

they say they calculate it from Heightmap, but u cannot get it from TerrainData, only in material on actual terrain

[fervent hatch]

you can see the entire fragment function in TerrainLitPasses.hlsl

it's Splatmap.Fragment

About heightmap, the code says this: // disable Height Based blend when there are more than 4 layers (multi-pass breaks the normalization)

[thorny swift]

Yes, I am in there, and what he is doing is getting the _TerrainNormalmapTexture, which is somehow created and passed into a shader, but where and how it is calculated is never mentioned

[rose sentinel]

Anyone know why my sand is so.... wet?

[rigid junco]

have you marked your normal map as a normal map, in the import settings?

or change specular to black, not sure I can't check in HDRP

or you have Screen space reflections cranked up... hard to tell

[proven crystal]

Combination of TerraLand and Easy Road...

[rose sentinel]

Its marked up to be a normal map,
Specular to black doesn’t do anything

How do I check screen space reflections?

[thorny swift]

Try assinging black Mask Map texture, if its not assigned it used alpha channel of Diffuse texture for optimization purposes.

[rigid junco]

Guess it depends on version, my HDRP terrain layer looks a bit different, and it's using the Smoothness slider correctly when no mask map is assigned:

[rigid junco]

Screen space reflections are a Post processing effect

but yeah, try with a black Maskmap texture first, like Kristian said

[rose sentinel]

Do you have an example?

[rigid junco]

Under Diffuse, Normal Map, etc, there is Mask Map texture slot. Try putting a black texture there

[rose sentinel]

any good free terrain asset ?

[quiet basin]

wet sand💀

[shell jolt]

wait, this is a bad idea...

make your own mask map accordingly

and adjust the property from there\

[rose sentinel]

I’m loving this community
You guys are all so responsive

[thorny swift]

we were not providing solution, mainly trying to debug why the surface looked all wet

[thorny crater]

hi! was wondering if Its possible to transfer the terrain I made in another project?

[rigid junco]

yeah that was for debugging..

[rose sentinel]

doesnt work

[rigid junco]

are you using the default terrain shader or custom?

and wdym doesn't work, nothing changed when you put a black maskmap?

[rose sentinel]

nothing changed, and yes i am using the default terrain shader

[rigid junco]

hmm, try turning off post processing in your sceneview, to see if some effect like Sreenspace reflections is causing it

[rose sentinel]

I dont have it on.

literally everything i have in my scene lol

[rigid junco]

well, post processing could be in your Camera gameobject for example... but if you say so I believe u

If you can take a video where the camera angle changes, it's easier to pinpoint what causes that. Otherwise im out of ideas

(you tried adjusting the smoothness slider right)

[rose sentinel]

@rigid junco

nothing lol

[rigid junco]

I mean turning the camera a bit

but it does indeed look like your smoothness is just cranked to 1 somehow..

[rose sentinel]

its weird

[rigid junco]

yea I would test if you can produce this result with a new terrain and new terrain layer

[rose sentinel]

remade it

doesnt change

[undone ferry]

Not sure if this is the place to ask but I'll give it a go. Tryin to make something BIG, and I've got multiple terrains on the max setting of size. I want to edit them each individually, however no matter what I do it just keeps editing them all. Is their a way to make this possible?

[rigid junco]

It sounds like all your Terrains are using the same TerrainData asset?

you need a separate one for each

[undone ferry]

I will give her a shot when I can, thank you for the response!

[regal atlas]

wow i suck at making terrian

[olive musk]

what is the difference between tree and details on terrain? any performance boost on details?

what are trees? are bushes tree? are rocks trees or details? can detail have colliders?

[proven crystal]

😊✌️

[undone ferry]

@rigid junco Any chance I can send you a DM? I tried what you said with the TerrainData asset thing and it worked ish?

[rigid junco]

aight sure

or just make it a thread

preferably

[undone ferry]

I'm actually not sure how to do that but I can keep it here

I have 20 terrain panels, yesterday when I edited 1 they were all edited. I did the thing you said changing the TerrainData ASsets and it worked to the point where when I edit 1, it edits the 10 on the top half and then if I edit one of the bottom it does the bottom half

[rigid junco]

just sounds like they arent actually referencing individual TerrainDatas?

but still sharing some

[undone ferry]

I think? I'm not sure I'm still new to all of this. But in the "Terrain Data" section in the "Terrain Collider" they all have different "New Terrain" 1-20

[rigid junco]

oh no you need to also set it in the Terrain component too

[undone ferry]

Would that just be in the Terrain Settings?

[rigid junco]

I don't see it in my settings, looking atm... not sure where it is

[undone ferry]

I appreciate the help

I tried googling around but I felt like I was just smacking my head against the wall lol

[rigid junco]

this is a bit confusing, i can't seem to be able to do that either

ill look around

i need to do it soon too anyway

[undone ferry]

I appreciate it, if you can't get it no worries. I think I'm biting off a little more than what I can actually chew ya knwo

[rigid junco]

Wait. Did you ever try to delete those extra terrains and just creating ones with GameObject > 3D Object > Terrain in the top menu?

that creates a new terrain with its own terraindata

[undone ferry]

So I did that, but then deleted the terrain it made (since I had my grid all set up) and the asset stayed so I individually changed it down in the collider

[rigid junco]

oh okay

[undone ferry]

Maybe I just have to do a new one each time and then just go from there?

Instead of duplicating for ease

[rigid junco]

they are in your collider only, not in Terrain

if you drag a TerrainData in the TerrainCollider i mean

[rigid junco]

yeah

I don't think duplicating a Terrain gameobject is that healthy it seems

the TerrainData gets shared or otherwise messed up

so I'd delete all but 1, then create each new one with the menu i said above

you can use the same Terrain Layers (the "Textures" or "ground materials") across different Terrains so it shouldnt be a problem

[undone ferry]

Thank you so much for the help, a lot of this is very overwhelming

[rigid junco]

I understand

[rigid junco]

just start with this i say

GameObject > 3D Object > Terrain

good luck

[undone ferry]

thank you again :D<3

[cloud bone]

Hello, do any of you guys know why in URP (dont know if in built-in) the Draw Instanced Terrain makes the terrain not read the Ground color from the skybox ( (Lighting -> Environment -> Environment Lighting (Gradient) -> Ground Color))?

[shell jolt]

that's known issue for years and nothing we can do about it without using custom terrain shader... see this issue https://issuetracker.unity3d.com/issues/terrain-is-not-affected-by-environmental-lighting-when-draw-instanced-is-turned-on

still under cosideration like.. why? 😵‍💫

long story short, it will break the terrain instancing you can try this yourself with your own custom terrain shader if you wanted to

the instancing for the terrain is unlike any other method, it splits the mesh into chunks

[cloud bone]

thanks a lot slim!

[mental orchid]

hi guys im new to unity

I'm trying to find the shortcut for erasing texture paint (brush) on the terrain-tools but there is no information about that in the manual.
Is there a way to erase paint brush strokes while painting on terrain?

[rigid junco]

You would have to just paint over it with another TerrainLayer

[shell jolt]

would changing splatmap resolution on an already sculpted terrain change the look of the terrain itself?

[jagged ferry]

Hey guys! does anyone know a way to fill in under a terrain?
Basically a way to make it so that there are no gaps between my concrete cube and the terrain

any clue on what it could be?

[native basin]

I don't have the option to add roads

does anyone know how to fix this?

[winter minnow]

There is no built-in functionality for roads

Roads are most commonly some type of procedural mesh

[native basin]

in this tutorial he has road

[winter minnow]

ER seems to stand for "EasyRoads", a custom asset

[native basin]

well what about if I want to make a road object a tile so that when I stretch it it creates multiple and doesent stretch

[native basin]

I have it

[winter minnow]

The documentation of that asset might give you more detailed advice how to use it

[still tendon]

Hello, can i add lods to terrain detail prefab?

[shell jolt]

You cant currently, due to the bilboarding system it has

You can use tree tool to do it tho

[still tendon]

does it apply billboard to the mesh automatically?

[still tendon]

can u recommend me the tool ?

[shell jolt]

It should as long as your shader compatible with it.. such ad soft occlusion shader for the terrain

[shell jolt]

Wdym.. its there already..part of terrain tool

[still tendon]

ah sorry misunderstood, i thought i needed to use another tool to configure the detail mesh

[still tendon]

Do you think the tree tool is less performant?

[shell jolt]

wdym 😄

Make your game 1st 🙂

[still tendon]

I think i should do some research before asking someone questions 😄

[shell jolt]

goodluck

[shell jolt]

opened a thread begging for a new feature, terrain-tool in Unity is lacking some love tbh... https://forum.unity.com/threads/feature-to-make-terrain-walls-from-custom-meshes.1340786/

feel free to chip in, and hope the devs actually take a peek of it... proly not.. well, at least I tried 🙂

[still tendon]

thanks

[native basin]

is there a way to just stretch this so that it copies this tile over and over instead of setting the tiles one by one?
Image

[muted hinge]

Dunno if this is the right place to ask, but does anyone know if version control would be able to merge two people working on the same terrain or would there be conflicts?

I'm guessing there probably would be conflicts considering it works off a singular terrain data file of which isn't very conflict resolvable

[shell jolt]

YOu can just stretch it, the resize tool is there in the editor already... Also that means you'll stretch the texture as well, and not what you're looking for

you'd need something like a triplanar-like shader or something along those lines to be able to stretch the object without messing the texture

[native basin]

I found a way, I just stretched it and then set the tiling higher. But thanks regardless

[bold dust]

Im trying to make an intractable city in my game where should i start Im trying to figure out how i should make the buildings and roads ect

[dusk shale]

help i put a texture in my terrain but now it is blue

here is the texture btw

[dusk shale]

is it the urp

[steady pasture]

look at your terrain texture and see if it is blue

[steady pasture]

wait, could it be that you used the normal texture instead of the diffuse/albedo/main one?

[dusk shale]

my texture is not blue

i checked it twice

imma try another texture

[dusk shale]

the texture type is

i dont want a smurf game 😭💀

that never happened to me

[dusk shale]

helpp

it was the lighting 💀

[cinder spindle]

I'm getting weird light spots on my terrain on IOS, does anyone know what causes this?
This problem is on IOS only, looks fine in editor, and on Android

The project uses URP

[cyan copper]

hello, i have a prefab composed of 3 objects i.e. 3 meshes. how can i use it as a detail mesh to paint onto terrain? currently when i try using it as detail mesh it separates them apart... how to make them stick together like a normal game object?

is there maybe a tool to combine 3 distinct meshes into 1 as an asset / mesh / prefab?

[minor forge]

my tools are glitching... i can not access all the settings and tools, because somehow the unity layout is not working properly with the terrain tools. sometimes restart helps, but i dont want to restart 3 times per hour... any fixes or solutions?

[minor forge]

is the terrain collider paper thin? i mean that if i hit it with small projectiles are they likely going to fly though it without colliding at all? i originally made my game with just simple cube shapes and they can have deep colliders. i am now changing to use the terrain tools, but i am thinking that should i leave the cube shapes under the terrain collider so there is less projectiles leaking through the "floor"?

[rotund drum]

Any tips for optimising terrain for WebGL builds? maybe some good assets or example projects are known for you??

[shell jolt]

instancing as much as possible, do note that the browsers must support at least webgl 2.0 and above

[rotund drum]

And what is best way to control shaders? I wrote custom shader scripting code for everything else, but it seems it fails to strip terrain shaders, and in webgl it uses woping amounts of memory (thanks to addressables problems.)

[shell jolt]

Not quite sure what tou mean by that tbh, sorry 😫

[rotund drum]

If you use Addressables, the webgl build includes all possible shaders variants into your memory. Normaly you can select shaders you want with shaders collection and strip everything else on build. But it seems terrain does not work the same way, so I thought maybe anyone knows some tips about that.

[shell jolt]

Proly #archived-shaders is the best place to go for this...

[rotund drum]

Is there anyways to reduce terrain Splat maps sizes? or make terrains load into memory dynamicly that it woulnt load those huge textures into memory?

[shell jolt]

Yes, its called instaced terrain, which already there, you just need to toggle it on, in the terrain settings

[rotund drum]

This one?

[shell jolt]

Also note, that it has its own limitation in terms of making it works with pp or even custom render feature

Yes

You'll noticed that your terrain drawcalls now reduced like by a heck lot

[shell jolt]

They already working on this, and its in their roadmap for 2022 I think

[rotund drum]

With instancing yes I noticed it as well. it looks way better than usual 😄 by the way, why I cannot see shaders group in graphics section by default?

[winter minnow]

Fast moving rigidbodies should use some type of continuous collision detection which calculates their path in motion to see if they hit anything regardless of speed

[shell jolt]

replacing tree instances with MeshIndirectInstanced 😃

[ionic ice]

G'day guys, so I basically have no artistic flare in me and need some help with a terrain 😅 basically im making a "synthwave endless runner". I need my terrain to basically just have that purplish neon box look - but I have no idea where to start lol

[shell jolt]

Look up for volumes if you're using URP

and learn what the overrides there would do to the game

[marble sentinel]

I am currently on Unity 2021.2.5 URP

[marble sentinel]

is there a way to force Unity to not draw on the terrain I currently pressing my mouse on but only on the selected one? (I have overlapping Terrain and it messes things up when unity thinks I now want to draw on the other one while I don't actually want to

My current workaround is to entirely disable the other terrain which doesn't seem like is should be necessary

[winter minnow]

I'm curious why overlapping terrains? It sounds like a workflow they didn't expect when designing the system

[marble sentinel]

Caves

I use one overworld terrain and another one for an underground cave

Underground Terrain:

Terrain Ontop

Transition without Props:

The problem I have is that when I draw ontop of the cave on the standard world terrain it sometimes bleeds through and also alters the cave terrain. Which was really annoying since I had ro reshape the whole cave^^'
Till that point I was just assuming that different Grouping ID's would be enough to not cause any bleeding. turns out Grouping ID doesn't care about that

[winter minnow]

Ah, that does make sense
Still, probably not something they anticipated

[marble sentinel]

Yeah, I wasn't assuming that there was an easy fix for that but hey, why not give it a try

I appreciate that you took your time to listen to my problem Spazi 🙂

[shell jolt]

toggle off the AUTOCONNECT and make sure the two terrains does not have the same group id

BACKUP 1st!

note, most common operations such as raising, setHeight etc would still affect it... this proly a bug on their end

[shell jolt]

We use bunch of terrains in our project, the way we do it is to model the terrain separately in edit mode THEN COPY the TerrainData, and on runtime just reconstruct 1 or 2 terrain over and over

including the treeInstances

[marble sentinel]

Yes setHeight and raise are the ones I use most which is why Grouping ID is sadly pointless here.
Different Grouping ID only let's me place a neighbor tile on the same place(which is also necessary but already done)

[shell jolt]

GroupingID only for when you want to AutoConnect the terrains in the same group

also, they don't lock the placing of the terrain now, unlike in the old days, so you can freely move them, as long as they're not connected to each other

[jagged cloak]

hello guys im trying to make a tunnel in blender with multiple cube and when this is used in unity editor the framrate dropped a lot , is there anyway to fix it, did i do it wrong?

[shell jolt]

I doubt that is the case, but just in case, turn on the statistic info in Blender and see how many vertices the object has

also how many objects just for that one tunnel?

and how many materials used?

well, you used tons of objects there just for one tunnel 😆 .. afraid not..

you can merge those into single object, then apply the transform, and then unwrap the UV

if you want each faces has different color for example, you can just detach the faces by pressing Y in edit mode, and apply the transform again then unwrap the UV

...even so, your lag should not caused from just one tunnel 🙂 ... but who knows, perhaps it has millions of vertices 🤣

[jagged cloak]

yeah merge all the object did the trick ! Thanks a lot

i just started to use blender for like 2 hours

[naive storm]

why is my terrain doing this?

[naive storm]

?

[marble sentinel]

I can not tell you why it does that but my guess is that its some sort of rounding error shenanigan that happens at the border pixels between terrains. So I can not give you an explanation, just a solution:

Fix it by hand. The best way I found is to use the Smooth Height tool and set "Smooth Controls - Verticality" to 1 (Maybe this is a Feature added through Unity's "Terrain Tool" Package not sure, it is NOT the standard terrain it is an extra package that you need to download to Improve the standard Terrain, but it is 1000% worth downloading since it's free and adds really powerful tools for when you work with terrain)

Setting the Verticality to 1 means that the Smooth Brush will from now on only elevate your Terrain which is perfect for your situation

[naive storm]

i fixed it in the end, i did some stupid terrain raising stuff to fix it but i later realised that it can be fixed with the smooth height tool

thx anyway

[marble sentinel]

Do you have the Terrain Tools installed?

[naive storm]

yeah

[marble sentinel]

Perfect 🙂

For such situation Smooth is really handy since its less destructive than add or set height so its my fav solution^^

[naive storm]

yee

[strong swan]

can someone please help me with importing bob omb battlefield into unity? when I put the model into unity it's just gray

[cyan copper]

is it possible and are there scripts/assets to the effect of procedurally painting terrain texture based on Y height? ex. i want dirt/rocks beneath water level, i want wet beach sand right at water level, dry beach sand for 1-3 units upward of wet sand, then pretty much grass texture higher than that. can that be scripted / automated so it doesnt need to be painted manually?

[rotund drum]

I have question as well. So I build scene on webgl with Terrain. Stripped not nessasary shaders. And what I got quite interesting.

1. PC -> no problems
2. Android 8 -> no problems
3. Android 12 , iPhone Xr-> Terrain shader is invisible. Bushes are visible, but not terrain it self. Culprit option -> Draw Instanced Without it terrain is beeing rendered.
   Unity 2022.1.16
   Anyone had seen similar problem or have any tips.

[shell jolt]

It is a common knowledge that instancing requires hardware support...

and why the heck you want to strip terrain shader 😃

webgl features different from one browser to another.. especially ios, it's very restrictive there in terms of what can be done and whatnot

[tender lily]

how do i increase render distance?

ihave plenty of trees, but they arent visable and the shadow map aint showing unless im close to the ground

[rotund drum]

Striping is nessary to reduce memory usage. I am striping it completely, but only parts it does not use. Example of URP. If you use addressables with it, it will add all shader variants to memory and build,. and that is 180-300 mb of RAM. While stripping only shaders variants that are needed can reduce it to 3Mb in memory. As for webGL project it is quite big isnt it? Also I was able to make it work with instancing on mobile devices, but price is quite heavy:

I dont really see why terrain shader should be 18mb + 12 +9 in memory

[rotund drum]

in scene editor

you might want to remove dinamic cliping

[rotund drum]

Maybe material problem?

[polar olive]

Hi 🙂 Have someone link (or a tip) me to a tutorial on how to render very large terrains performantly (LOD...GPU/VRAM)..? It is about size of at least 10x10 km - Visibility must be >= 5 km

[rotund drum]

Oclussion culling is one of the things you will want to check. Other is To split terrains into multiple terrains and handle group what load unload. Also draw instanced is also big improvement. Well this is basic but still

[shell jolt]

Common way to do it is to split them into chunks..

A recommended way to do it is to have just 1 main terrain, split that huge terrain into chuncks, dump their TerrainData, then just reconstruct the terrain with the terrainDatas over and over. This way you can have multiple artists working on multiple terrains at once and at the same time on their rig and just copy over the TerrainData

tho it's not beginner friendly so to speak

[polar olive]

@rotund drum OC - that anyway 😉
@shell jolt Hm..how can i split an ready mesh generated by DEM data? Or have i to use smaller DEMs and put them together?
Splitted in chunks i can add LOD.. of course

[shell jolt]

LOD is least of your concern here, Unity terrain system has instanced terrain so it would not be a problem, as for the trees it's up to you... seriously, make the game first then lod all the things later

[minor forge]

is this automatically writing over the terrain data even on hard disk and not only runtime memory???

i had a nice pre made map, but it seems i destroyed it with trying to change it on code

[minor forge]

this is my new procedural terrain (on the right), and it somehow over writed the old hand made one...

[desert galleon]

what should i start to texture for cartoony 2d game terrain, ex stone grass?

[shell jolt]

Without custom shader or toon ramp the best you can do is to turn on height blend feature and ramp up the alphamap resolution, note, this just to get a sharp blend color NOT the toon lighting

that said,custom terrain shader is the way to go..

[shell jolt]

also note, instancedTerrain won't work with custom passes

hope they fix that in the near future 🥲

[rose sentinel]

how do i make it

so the grass

always renders

or make it render further away

[shell jolt]

you can set the distance if you're using terrain-detail OR if you want to have more control over it, say your own lod and whatnot, just use the tree tool to scatter the grass and add lodGroup to the grass prefab

the terrain-detail uses bilboarding and the default sorta looks ugly, just saying.. you'll notice this immediately

[shell jolt]

Opened a discussion on forum, pouring my thoughts regarding unity terrain, specifically for terrain maganement. Feel free to jump in and share your thoughts https://forum.unity.com/threads/terrain-management.1345586/

it's a nice tool in Unity, but lacks some devs love 💔

[rotund drum]

What shader variants terrain uses differently on WebGL IphoneXr and android 12 ? As same shaders does work on windows and android 8, but not on other models. And editor shaders collection does not add them automaticly and they are invisible on phones.................

ANy secret key words?

Cant include all shader variants, as that is just too much memory

[shell jolt]

as said, webgl capabilities are not the same across browsers... it is a common knowledge that it's more restrictive on ios... check their requirements

[rotund drum]

if I add all shaders then it is visible. so it is not exactly about compability. it is just uses different shader variants

[night dirge]

How to assign trees to the terrain?? I defined tree and bend factor, but I can't delete the default mesh renderer that is invalid. How to do so?

[shell jolt]

add lodgroup to the tree, thats the requirement for the tree, or use soft occlusion shader so it can be bilboarded... that said, it is recommended to make lod for your tree model... lookup what is LOD / level of detail on google

[shell jolt]

Set the cull distance of those trees, you can find it in the terrain settings

[trail perch]

how do i get rid of the jagged edges of the texture on the terrain? I found that decreasing terrain size fixes it but that also makes the whole terrain too small for my project so i can't do that..

[shell jolt]

raise the heightmap resolution and the texture resolution in the terrain settings

changing the heightmap resolution may change your already made terrain, so backup 1st and just incase shit happens

[tepid turret]

I get this error when I try to use terrain tools any pointers?

[rose sentinel]

Tiling's way too obvious

And I want a quick fix that only requires changes on the textures or terrain layers

That isn't scaling up the textures because it just makes them look weird or even more obvious

[shell jolt]

it depends on how your texture was made, and the environment lighting can help hide the tiling pattern that can be seen from a far enough range..

Other than that, look up for stochastic material

[lusty cove]

Hello, I have a terrain file that is combined with a total of 20 pieces composed of multiple raw files.
Can anyone suggest a way to get this properly combined with the other parts equally?
It's really, really hard to set the coordinates manually.
When I do it manually, there are gaps between them and an ugly image is formed in the game.
https://gyazo.com/b639708c15666bc3dde86c408d4c7ac0

[winter minnow]

Usually the best option is to use "neighbor terrains" instead of multiple separate ones

[lusty cove]

Thnks but how ?

[winter minnow]

https://docs.unity3d.com/Manual/terrain-CreateNeighborTerrains.html

[lusty cove]

omg thanks..

[rose sentinel]

I'm using unity's terrain samples

[frigid parrot]

Is it possible to create a blockout in unity for scale then export those cubes to blender to then model off of?

[winter minnow]

The FBX exporter package is worth a look

[shell jolt]

fbx exporter used to work (never tried it on recent projects), it took a lot of time to finish, like super long, and if you have humongous terrain with high resolution heightmap, expect it to be stuck

just be careful

[lusty cove]

hi

I have more than one neighboring land, but I want to merge it into a single land, how can I do it?

It is very difficult to organize this way.

[shell jolt]

it might be, but you can completely cull those chunks and gain performance... which is quite a common move for multiple terrains setup

[fickle nebula]

is there any easy way to grab a mesh from a terrain?

[fickle nebula]

hmm it seems it is easy to grab a mesh from a terrain in the editor, but doing it realtime appears a challenge

[weary jacinth]

hey everyone, im getting this strange issue with the terrain grass where it seems to lose its transparency and has a black background when in the build version, but looks fine in the editor playmode. im using a terrain data cloning script to clone my terrain data so that changes to the terrain made at runtime do not affect the original terrain data: https://gist.github.com/Eldoir/d5a438dfedee55552915b55097dda1d4

[iron aurora]

is there a way to turn regular terrain into blocky terrain? I am not interested in procedural generation or anything, just looking for a quick method to create voxel terrain.

would be great if it'd be unity terrain so I can paint meshes onto it

[winter minnow]

No
Your easiest way to get voxel terrain would be to use Blender's voxel remesh, but forget using Terrain for it

[shell jolt]

Not the shader that supposed to be doing that... you want to make your own painting tool and get the direction of the normal of the terrain mesh your brush is painting

not hard to make, you can proly find tons of this on github

but I do agree that it supposed to be part of the feature

[shell jolt]

@silk needle just checked in 2022, terrain v5...

only for detail mesh...

which still very much appreciated, really

which also means there's a new apis added for this, which very useful for custom terrain tools ♥️

Not sure if I should post here or in one of the code ones, but I have a perplexing problem.
I'm making this ingame terrain editor. It can adjust the elevation of the terrain with a brush. How do I convert the world space to a terrainData.setHeights compatible array? The values of the setheights array seem to be close to 1/2 the value in world space but not exactly. If I basically make the world space position / 2 equal to the terrain height array value I want to change, it's never exact. It's close enough towards the 0,0 corner but the further away from that corner I get, the more incorrect my values are. What are ways to calculate the correct terrain height array location from a given world space vector3?

ah nevermind. It looks like terrainData.heightmapScale gives you the value that you need to divide the world space coordinates by in order to get exactly the correct heightmap coordinate. On this particular terrain, that value was 1.95 which explains why dividing it by 2 almost worked

[minor forge]

i had to use pen and paper to figure it out. i was making procedural terrain generation and there was just too many things that i could not fit in my head at the same time. fun part is that terrain array's 0,0 was not in the same place as the scene's unity 0,0,0 coordinates. of course the scale is different. and the terrain x,y vs unity x,y,z do not match each others and while in north z gets higher but in terrain data y gets lower... and when i finally got it kind of working i think i still had to rotate the terrain map 90 degrees

[lime oyster]

someone that knows a nice asset to like help me to generate a lower scaled map of europe?

money doesn't matter

[fickle nebula]

i remember blender having a plugin to do this, although i dont remember the specifics

[fickle nebula]

this might help, although i haven't personally tried it https://www.youtube.com/watch?v=Mj7Z1P2hUWk

[lime oyster]

I have seen that video but want something that makes the trees, textures and basically all the things like the asset terraworld pro

cant use terrapro becouse it doesent support that big things and I cant down scale it in terra world

[fickle nebula]

hmm, fascinating, i dont know of anything personally, i wish you luck though in finding something that does that though!

[lime oyster]

thx ❤️

[jaunty hollow]

I cant change the texture of my terrain, can somebody help?

[rigid junco]

click the gear icon in your Terrain inspector, and change Material to something that works

enter "terrain" in the material search

[jaunty hollow]

ok i found it thanks, I must have missed it when looking through the terrain settings

[ornate dirge]

Does anyone have experience with using terrain editors for Unity, such as Atlas Terrain Editor, or Gaia, but at runtime? (For instance, for creating a procedurally generated terrain at runtime)

hi im placing trees in my game but for some reason the trees arnt being placed on the terrain and being placed below the terrain heres a ss of the issue

[echo sage]

does anyone know how i can fix my grass from overlapping so much?

i want it to look like this

[shell jolt]

its a common mistake.. change the world origin of the tree in Blender or any 3d software and save it back, Unity will soon update the position

make sure the origin sets right at the root level of the tree

[shell jolt]

in Unity 2022 (Terrain package v5.0.1) there's a new and much improved algorithm(toggled OFF by default for backward compatibility) for scattering which fixed most of the overlapping issues, you need to toggle it on in terrain settings.

Backup 1st!

[hoary ore]

How do I do that?

[shell jolt]

google up, tons of it there :).. you're on your own from here, goodluck..

Also, Didn't I already tell you how to do it, did I? 🙂

[fathom reef]

Why can't I duplicate an modify copies of terrain regardless of what process I use to do it?

Why can't I rotate terrain?

[winter minnow]

Terrain's data is not contained in the gameobject with the terrain component, it's in the referred terrain data asset
Because the terrain mesh is entirely procedural and the specific kind of optimizations it uses internally, it must always remain axis-locked
The terrain will rotate if you rotate the data such as the height map, though practically only in 90 degree increments

If you google the question you might find scripts to do that with

[fathom reef]

I've tried rotating in 90 degree increments and failed. 🤔 I'm aware of the terrain data asset importance but when you copy and rename it, I cannot get a copied terrain to accept the new data, it always asks me to revert. I've google the question and I've only found 10 years of questions without proper answer. (the first question).

[winter minnow]

To clarify, the height map raw image (as well as splatmaps and other data) must be rotated on pixel level, so that the terrain itself doesn't rotate

[fathom reef]

I'm not sure what that means are you saying like copy, rotate, paste type thing?

[winter minnow]

The terrain component will not rotate, ever
But it can read a height map image that's rotated

[fathom reef]

is there a reasonable way to rotate a height map?

[winter minnow]

Export raw image, rotate in a program that can do that and export and import with exact same raw export settings (gimp or photoshop)
Or try one of the scripts people have made to do it automatically

[fathom reef]

Hmm, I think I understand, thanks very much

[rose sentinel]

How do I add a material

[winter minnow]

Look up in the documentation how to add terrain texture layers

[dense wigeon]

Hey guys I have a problem. I want to use the Terrain "Paint Details" tool to paint some small rocks on my terrain but I cant add a Detail Mesh because my rocks have LODs and I get the error "LOD Group component is not supported. I also tried to paint them with the "Paint Trees" tool but there I get the error " The tree couldnt be instanced because one of its LODs contains renderer of type other than meshRenderer and BillboardRenderer". So is there a ways to simply just paint my rocks with LODs on my terrain?

[late snow]

guys please help, this has been a problem for a while now. I can't draw flowers or grass or even trees on my terrain, how do i fix it???

[shell jolt]

unity's terrain is pretty vocal regarding errors and warnings... see what it says in the console tab..

if it's nothing there, fat chance your trees were painted BUT spawned somewhere else due to the incorrect origin

[wheat fox]

I need help, my terrain looks like this now. Yesterday when I closed Unity, it was normal but now it looks like that. (Those are textures)

If I try to paint textures, the indicator is like that now

[south canyon]

Is there a fix for this bugged out/dancing Tree Painting palette issue?

[shell jolt]

yes thats a bug in certain terrain v4.x... it keeps refreshing the terrain inspector when scrolled,, they fixed it in v5

[grand aurora]

How to make a spherical landscape with gravity ? I want to make a planet where it has trees water land etc

[winter minnow]

The terrain system itself doesn't support spherical shapes, but you can use meshes
Gravity is just a physical force towards a direction, or in this case, a point

[polar verge]

How do I make the detail objects smaller

[mental bear]

How do you paint a texture on your terrain, I've made a brush but it just doesn t do anything

[blazing pecan]

I'm not sure if this is late but there's probably something wrong with your material and lod. Unity does support subshaders on different lods so if your trees have special materials make sure to check that.

[tiny tide]

any idea how i would take a Terrain and put a high-detail golf-size cup/hole in it?

Can someone please tell my why this stupid game engine terrain won't work?

I try adding the other terrain data to the terrain, then it says some stuff and does absolutely nothing

Well I got that fixed, but now it's just pink

[tiny tide]

Thanks!

https://streamable.com/gbk0gh

made a little physics-based golf sim yesterday and it's my first time using Terrain

[verbal nest]

Nice!

[tiny tide]

since the game is physics based, i need to fake physics reactions based on which "ground material" the ball is on

now I have a system to do all that 👍

[verbal nest]

I'm not sure what method you're using to make the ball go slower on certain ground types, but there's a thing called Physics Materials that would be perfect for this (I think), but I'm not sure if you're already using that or not.

[tiny tide]

can you paint physics materials on terrain though?

my issues is that my terrain is one single mesh (idk if that's all Terrain by default)

[verbal nest]

I'm not sure, but afaik not. I'll have a quick look

[tiny tide]

even if it's not possible, i think this solution is good for me

usually when i have a ball roll between 2 different meshes, there's always weird interactions

so one single mesh is ideal

[verbal nest]

Ah yeah

It's not possible

I'd just use one standard terrain for the grass, then make seperate meshes for the other patches

[tiny tide]

Oh idk if you saw but I went with this earlier and it's already working great #⛰️┃terrain-3d message

[verbal nest]

Ooh thanks for linking that. I need something like that too for audio lol

[tiny tide]

So the only way i was able to add a hole small enough with enough physics mesh resolution is by cutting a low-resolution hole in my terrain and patching it with another mesh

this is what my terrain looks like with the other mesh removed

It will work, but I really hate this solution

[bold iris]

is there a program in creating mesh?

[shell jolt]

Wasn't really clear what you mean by that, Unity can do primitives and there's Probuilder to do some basic stuffs.. other than that use 3d software like most of us will ya 🙂

[rare cypress]

what would be a simple and performance friendly way to implement grass into hdrp?

since it doesnt support it in the way urp does

[winter minnow]

That's probably explained in the link

[tiny tide]

how can i convert heightmap coordinates into a world position?

[shell jolt]

simple..

        private Vector3 TerrainPosToWorld (Vector3 pos)
        {
            return Vector3.Scale(pos, terrain.terrainData.size) + terrain.transform.position;
        }

[tiny tide]

Doesn’t that completely ignore resolution though?

[shell jolt]

nope, give it a try..

[tiny tide]

doesn't work as i said

because resolution is completely ignored

    {
        return Vector3.Scale(pos, terrain.terrainData.size / terrain.terrainData.heightmapResolution) + terrain.transform.position;
    }```

This code is the only code that gets me 99.9% accurate

You can see the blue line isn't intersection a terrain heightmap point though

[tiny tide]

@shell jolt I got it working. Heightmap resolution was absolutely needed in the calculation

A resolution of 1025x1025 is actually 1024 resolution

Unity had a major bug lol

Has*

The reason it was off is because I needed to subtract 1 from the resolution value

[shell jolt]

it's not a bug, the formula is power of two + 1

glad you solved the issue

[cunning tendon]

I made a model in blender that looked all fine but when I import it into unity it looks weird depending on how I look at it, please help me fix this

also I rendered it in blender and it was fine

also also the top (normal) part and the 2 not normal rings are joined so idk why they are different

[shell jolt]

you have flipped faces... go to Blended, turn on the Face orientation if they're red, yeah they're flipped

you can do :
Select the red faces -> select Mesh in the menu tab -> Normal - flip -> done 🙂

[tiny tide]

according to most people that work on terrain assets, it's an oversight/bug

it's outlined there sure, but the calculations done using the value by Unity don't account for the actual resolution

[rigid junco]

How do I access all the terrain's layers from a shader? I only figured out how to access the first 4 layers. How does Unity pack the rest? 🤔

Using HDRP

[warm radish]

Heya. Which value used by Unity doesn't account for the actual resolution?

The function that SlimStv provided would work if you were going from UV position to World XZ position (You shouldn't have to account for the -1 pixel offset with this). Your solution works if you're going from actual texels to World XZ, if I'm reading that correctly. Depends on what each of your incoming pos values are. To me, it looks like you both were using different spaces for the positions?

[tiny tide]

yeah I'm speaking strictly on texels I guess since I'm working with direct heightmap coords. I don't work with the underlying Terrain system directly, so the Unity comment came from people working more closely I.E the new MicroVerse asset

Are there any sort of functions that exist already that I missed that would convert the texel position to World XZ?

[warm radish]

Not that I know of. If we did, it would pretty much be what you shared for converting texel pos. Most of the functions we do have for converting from different Terrain spaces exist in our shader headers

[tiny tide]

No worries. I have my solution and learned something new, so I'm good to go.

Now my struggle is onto tree colliders...

I need a way to have complex tree collision meshes without having to hand-place uniquely detailed primitives for each tree.... 😦

[warm radish]

Is the struggle getting any colliders to work at all, no matter how simple, or is it that tree collisions don't work with something like a mesh collider?

[tiny tide]

the latter

There's no perfect solution because mesh colliders will have weird geometry for the leaves

my hope was that there would be a tool out there that loosely converted a tree to a series of capsule colliders to approximate

[warm radish]

Ya. I think our tree database system also will only use the collider on the root GO for the prefab

[tiny tide]

What are potential solutions out there for having a complex tree collision mesh?

I'd have to imagine other games already needed this instead of a simple capsule

[warm radish]

How were the trees authored?

[tiny tide]

They aren't using a unity Tree component

[warm radish]

If you can isolate "segments" in the tree ie via the mesh edge loops, you could generate colliders for each of those

[tiny tide]

They are assets from NatureManufacture which I'd have to imagine are popular right now given the Humble Bundle sale

I'm working on a golf game, so I need trees to not be 100% random for a player to deal with

[tiny tide]

@warm radish could I loop through the tree instance data and use it to spawn mesh colliders in the exact same place at runtime?

Just thought that one up, but seems like it could work

[warm radish]

Ya. That sounds like a good approach. Either at runtime or you could bake it in-editor (would save you some load times in your game probably)

[tiny tide]

I’m assuming there’s a way I can hook a build event to do that as a pre-build step

I like that idea. I might need to add some sort of proximity logic so that a shitload of trees in the distance don’t come into play

I’ll explore, thanks!

[mental bear]

I just made a tree in blender, placed it, changed the scale, made a original prefab and now when I mass place it with terrain tools the trees are the size of a rice corn

[ivory cairn]

Is LOD support ever planned to come to terrain system?

[tiny tide]

What do you need LOD support on?

[ivory cairn]

terrain details

the performance is horrible

[tiny tide]

I thought that’s all supported?

[ivory cairn]

oh as part of the terrain system

detail mesh

[tiny tide]

I know my Tree LODs work perfectly

[ivory cairn]

trees can have LOD's as far as im aware, the details cannot

someone I know made an instancer for details, but sadly its culling is buggy and its not his priority atm https://github.com/Milk-Drinker01/Milk_Instancer01

theres also no level streaming so you need to do that yourself

[tiny tide]

I’ll be honest, I got into Unity Terrain about a week ago and bought Microverse a couple days ago

So I’m still new, but maybe it’s supported there?

[ivory cairn]

its just crazy how poor it performs without LOD's

[tiny tide]

If Microverse stays independent of Unity I’ll be sad lol

Seems like a solution that’s so much better than their own that it just makes too much sense

@ivory cairn I don’t know if it solves any of your problems, but either way I definitely recommend checking it out

It’s a brand new asset

[ivory cairn]

I skimmed the video but didnt come across anything about details

if it uses default unity terrain details, LOD's wont be supported

[tiny tide]

Yeah it does which is why I didn’t think it would fix anything

I just still recommend it

As it does literally everything better

[ivory cairn]

honestly im not about to drop 160$ for a more streamlined terrain tool

terrain toolkit is good enough for now

the splines are cool tho

[tiny tide]

I feel you on price but I think you’re underselling it haha

Unity Terrain might as well not exist after using it xD

[tiny tide]

@warm radish i don't mean to keep going directly to you for help, but any idea why my terrain with 5 trees on it has a Tree Instance array at runtime with 300+ length?

[tiny tide]

also having the same problem as this thread you replied in
https://forum.unity.com/threads/paint-holes-creating-hole-but-still-showing-ground-texture.934125/

seems to be a problem with URP specifically?

I have "Terrain Holes" checked on my render pipeline asset.... I have multiple and they all have them checked

2/3 of the golf holes render fine

1 of them is glitched

in the Editor, everything renders fine

this problem only happens in the build

[thorn birch]

Has anyone had any success implementing tri-planar shader into a URP terrain material?

[warm radish]

Thread

Bug - Paint holes creating hole but stil...

[shell jolt]

True, which is weird, thus we used tree tool in our production to paint grass with our own lods.. tagging @warm radish 👀

And they don't give us with much freedom to tinker with the default billboarding system in there, which is an unfortunate

[warm radish]

Ya details with the Terrain system dont have LODs

[shell jolt]

Which, again weird... If it's indirect rendering then it makes sense, but it's just regular instancing 👀

[ivory cairn]

Is there any intention to make it?

[molten bluff]

is there any method to apply tri planar texturing in built in terrain?

or URP?

[molten bluff]

how to prevent texture streching on the terrain?

[winter minnow]

Modifying the terrain shader is of course possible, but tricky especially on URP
Your best bet is to find a shader like that someone has made

[molten bluff]

already has found

but doesnt get it work anymore

as its was 2012

lol

Tri Planar Terrain shader solves streching issues

[shell jolt]

You can remove the terrain stretching even without triplanar.. there's a mask filter for that

see how it's done here https://www.youtube.com/watch?v=p7T_GzQoGBk

Note, the values for mask filters different from one setup to another, depends on your terrain heightmap resolution

so if you get unwanted results after following the video, try to adjust it

...
Another method is to use Slope Flatten and set the vertical value to 100%

but this more of a manual work, it's up to you

[untold tangle]

Why might everything be black? Yes there are directional lights (The scene looks amazing in editor playmode but not in build)

[stray rivet]

Ambient light?

[winter minnow]

Generate lighting for each scene where issue occurs (baked global illumination does not have to be enabled, and should not be unless you intend to use it)

[untold tangle]

I disabled real-time GI and baked GI, it’s still black only in the build

[dusk citrus]

both the same file? if not, make sure the alpha channel of the texture exists

[upper sinew]

Could someone help me out? I'm willing to pay if things work out correctly.

This may or may not be the right channel, I'm very new to this.

[icy parcel]

Teh ask your question

[verbal nest]

Is there a way to use Unity's Terrain tools (the package that gives all the extra tools) without the splatmap/terrain layer sytem? I hate the system because it only supports 8 layers per splatmap which sucks in my case. I do want to use the other things the package offers though

[lament wadi]

I was about to ask something similar here but i happened to find this: https://forum.unity.com/threads/terrain-custom-shader-graph.1172447/#post-7510127
Perhaps this is also of use to you

[verbal nest]

Thanks Ill have a look

[shell jolt]

Shadergraph doesn't have a support for the terrain system, not yet... and soon we can .. hopefully very soon

here's the link -> https://unity.com/roadmap/unity-platform/3d-world-building

[shell jolt]

happens to the best of us https://en.wikipedia.org/wiki/Rubber_duck_debugging

wdym, most materials need 2d textures

you can use your own custom material, but there are requirements to make it work with the terrain system

also, why you want to do that? Thats exactly what terrain layer do

you can make your own MaskMap for the terrain https://docs.unity3d.com/Packages/com.unity.render-pipelines.high-definition@7.1/manual/Mask-Map-and-Detail-Map.html

also, don't just put a black texture there in the mask map

generate it properly, so you'd have a proper output

MaskMap is very very easy to make

sure, https://github.com/andydbc/unity-texture-packer

Just follow the steps to combine which channel is which in the maskmap link above

goodluck

Hi does anyone know of a way to dissolve the blue edges in my pro-builder model? Thanks in advance

[verbal nest]

Hey, I have quite a huge terrain (imported from real world heightmap data) and I'm wondering what the best way is to use it in Unity. Currently I split the 841km² terrain into 64 smaller terrains, but the detail is still way too low even at the Terrain's highest settings. Should I split the terrain up even more? Resulting in either 256 smaller terrains or 144 terrains. Or should I not use Unity terrain? I tried using Blender a while back but that was disastrous. My gaming laptop can't handle 841km² high detail terrain meshes in blender.

[verbal nest]

I split all the terrains. Now I have 256 but it still doesn't look smooth

Time to split them again. Let's hope my game doesn't break

Maybe my terrain scale is just off

You can't edit the trees whatsoever when they're on the terrain

dang okay

so when painting trees they are always gona be "colliderless"

https://docs.unity3d.com/ScriptReference/Mathf.PerlinNoise.html
I'm looking through the docs right now to figure out how the perlin noise in unity works, and I'm seeing

"float xCoord = xOrg + x / noiseTex.width * scale;"
And I'm just- very... very confused-? Say I had a texture that's like 1000 pixels large in width, and it started at 0,0,0.
If the x coordinate is equal to the original x, which would be 0 of course- and I add x which after the first iteration would be 1...
I would divide 1 by... a thousand? and then multiply it by one? (for the scale) so the new x coordinate would be... a thousandth forward? what- I feel like I'm missing something.

[rose sentinel]

I'm getting some weird artifacts when painting grass on terrain, screenshot here:

[shell jolt]

make sure that it's fully opaque before you export the texture.

that definitely looks like left-overs after you deleted or when you edit the texture

delete it with image editor

[winter minnow]

Set the texture's Wrap Mode to Clamp in texture import settings
If the issue persists, there's likely a problem with the grass UVs

[rose sentinel]

It is! I erased and erased

[rose sentinel]

Thank you - I will try that

[gentle prairie]

Does anyone know why is this happening? I have disabled anti aliasing on camera, urp quality settings (all 3) and in my render texture (to get pixel look I am using a low res render texture)

I tried increasing base map distance in terrain settings but no luck

[gentle prairie]

ok I fixed the shadows but the terrain textures are still the same

[rose sentinel]

the issue persisted. The grass is just a 2d texture, so when you say "issue with the grass UVs," wht do you mean?

[thorny swift]

the texture is mapped exactly as it is but the grass UVs are wrapping on top to the bottom as the nature of uv texturing, setting clamp will repeat last pixel information instead of wrapping to the bottom or left,right.

[thorny swift]

If you are using Unity Terrain use Refresh button after changing the texture import settings, so the Unity caches the newly imported texture

Also if you have more grass types, unity makes an Atlas to use for all of them and copies the import settings from one of em. So set Clamp mode on all Grass textures you are using. If you are generating MipMaps setting BorderMipMap can help too if the above does not

[thorny swift]

Looks like your grass texture has mip mapping on. Try turning it off or setting the FilterMode to Point.

[gentle prairie]

oh it worked ty!

[meager shore]

Hi all, im kinda new to unity, just a quick question, instead of going for extremely large landscapes would it be better to lower the scale of my landscape/terrain and also lower the size of my models or what is the best way to go about it?

Btw im trying to reduce the chance of FP errors that occurs from what I gather at around 100km squared + sized terrains

[shell jolt]

Split that into chunks...

[meager shore]

@shell jolt it is broken into tiles

but what im asking is, is it better to scale everything down or to maintain a scale and just make the terrain bigger to suit

im not very good at explaining things

[shell jolt]

scaling does nothing

[meager shore]

ok

so massiive terrain

[shell jolt]

it's Unity's terrain or your own?

and try tto fix the FP error through the standard tactics

world machine to unity

through the terrain tools

[shell jolt]

ah yes, that's the thing... With Unity's terrain the instancing is by doing chunking, this is the default with the InstancedTerrain... if you're not using Unity's terrain you should do this on your own

also, I'm not familiar with world-machine, so..

[meager shore]

I made the heighmap exported it in tiles to unity

[shell jolt]

oh ok..

[meager shore]

using terrain tools

[shell jolt]

that's fine

[meager shore]

it is around 88 square km

[shell jolt]

there's an option for DrawInstanced

you can turn that on and see if there's improvement, and backup 1st

[meager shore]

no

my problem is

my character

is able to traverse this

in literally around 15 minutes

where as im aiming for a terrain where I can traverse it on foot in like an hour

or more

or like 1 and a half hours on horseback

[shell jolt]

oh.. I see 🤣 ... I misunderstood that completely

[meager shore]

but my problem is it is also going to be multiplayer in my mind at the later future so what im trying to achieve

so do I scale the terrain up to disgusting size

or do I scale all my objects down and reduce the character movement speed

to suit

which better suits the engine?

[shell jolt]

all I can say, I won't use Unity terrain for that, I'd use my own tileable terrain system

so you can spwan them in the direction your character is going and still be tiled seamlessly

[meager shore]

probably going to be some form of streamer in the future but I would like to get an idea of the scale of things for the moment

[rose sentinel]

so I set the texture to clamp, clicked refresh, did all of it, but it's still showing the flickering line at the top.. I also opened the texture in GIMP and deleted anything I couldn't see at the top..

[swift iron]

hey i still cant figure out why my model wont work with the tree painter in the terrain tab, any ideas?

[shell jolt]

don't work can mean anything

it was added successfully as tree instance in the terrain? but when you painted you can't see the tree?

[honest moss]

Can anyone recommend me a good procedural Maze Generation tutorial for Unity 3d

[mystic thistle]

Does anyone know where I can get a good forest floor model? I want to do the texturing, but I just need to find the correct type of floor

[undone lark]

The correct type will be the one you custom make or pay for. Otherwise, search the internet and the Asset store for something useable.

[scarlet parrot]

I've no clue how to make an open world terrain any advice would be great.

[icy parcel]

You can use Unity's terrain tool to sculpt terrain as you want and then you'll need tilable textures, which you can paint on the ground using the tool,
Then you can place whatever you want on the terrain, like trees, houses etc

[scarlet parrot]

OK thanks

[rose sentinel]

Hello, how do I make my skybox change it's strength color so that it's more dark using code?

[shell jolt]

https://docs.unity3d.com/Manual/MaterialsAccessingViaScript.html

[shell jolt]

Couple things you can do :

1. LOD
2. LOD + Instancing
3. Indirect rendering (A bit tricky to get culling works)
4. Indirect rendering + LOD

IndirectRendering is what most people do to render millions of grass on the field with compute shader

you can find tons of tutorial on the internet about this

Why won't my terrain smooth properly? I have the exact same terrain (and settings) in URP (the vid is in HDRP) and it does smooth nicely

I've been having this problem for quite a while but I haven't found a fix

[verbal nest]

Well, Unity's terrain is officially shit

It won't even let me paint any textures onto it wtf

I've restarted, researched, and did everything I could to fix it

but nope

just won't work

[ebon dawn]

idk if this is in the correct area to ask but im having issue with polybrush if anyone can help

[elfin laurel]

why is this happening

when I place tress normally it will show a kinda cartoon outline when you are far enough back

but this is MASSIVE and black

not green like it should be

[shell jolt]

thats the default impostor as said in the terrain tool there in your screenshot

use LOD instead

[elfin laurel]

okay how do I do that Im sorry

[oak agate]

hey guys,
I installed the terrain tool package + the sample pack and it said, do you want to install dependencies so I clicked yes.. but I think it installed the HDRP pipeline thing with it and now my build takes insanely long, stuck on Shader Graphs/Standard Vertex Color.. is that due to HDRP being installed? I'm using URP so I dont actually need HDRP

[verbal nest]

Its possible to download HDRP and URP in a single project. It happened to me once, and the project ran fine. Just because you have both pipelines installed doesn't mean you're using both. I'd recommend waiting until it takes like an hour too long. Then once it's done remove HDRP

[verbal nest]

I added all the diffusion profiles of all the assets I'm using
Using HDRP. What is going on here?

The weird screen effect stops when I disable the terrain

[dusty canyon]

hey im trying to get the hang of unity terrain performance
if i were to dynamically load terrains from heightmaps ingame
whats the most performant way to do this?
should i have several smaller chunks, or larger chunks

[warm radish]

I added all the diffusion profiles of

[warm plinth]

Does anyone know of a Mesh/Spline Asset that can handle junctions/intersections with meshes that are connected in this sorta fashion? Doesn't have to be road-specific, Cities Skylines is just a good example.

[verbal nest]

Why would you want to intersect roads like that?

[hybrid tiger]

does anyone know how to fix this isoemtric tilemap issue?

im drawing it and it looks like its being drawn over

[lilac bloom]

There are many different terrain assets to choose between, like Gaia, TerraWorld/Land, World Composer, World Creator, maybe more. Does anyone have any tips for choosing between them?

[verbal nest]

If youre new to unity just start with unity terrain

[lilac bloom]

I'm not new to unity, I'm just looking at what's out there. I'm currently handcrafting my terrain in 100x100m chunks in Blender, which works fine for what I'm working on now, but if I want to go bigger or change art style, having one of these assets could be of great assistance

[verbal nest]

Ahh alright

[oak goblet]

Is there a way to get texture painting thats more in line with a stencil in that the pattern doesnt move while you move the brush?

rather than the pattern following the brush
