[warm radish]

Are you talking like a fixed world space or screen space stencil? What are you wanting to use as a stencil?

[oak goblet]

To paint terrain with the terrain layers, either one will do, I just dont like how it drags the texture across like an old windows xp program crashing

[warm radish]

hmmm. can you share a video? because that doesn't sound right

[oak goblet]

i can simulate what i want to happen with extremely small movements but id like to be able to sweep and layer different brushes

[warm radish]

ah ok yes. you can sorta. with noise patterns and features based on height using the "brush mask filters" list that sits under the brush alpha list in the inspector

for the noise, you have the option of keeping it in brush space (which is the just like the behavior you show in your video) or you can have it function in world space which would be more like your fixed stencil

this thing:

[oak goblet]

Interesting, which filter would that be? Height makes nothing happens, and "Noise" has things that look correct but neither toggle changes the brush

[warm radish]

let me start up a project with Terrain Tools rq. been a while for me

i'll share a vid and my settings setup

[oak goblet]

Thanks! I really appreciate it

[warm radish]

which Terrain Tools version do you have installed?

[oak goblet]

4.0.3

Universal Render Pipeline if that matters somewhere

[oak goblet]

Ohhhhh that makes a lot of sense, to avoid the brush shape and instead let the noise filter be the new 'texture'

[oak goblet]

this was really helpful thank you!!

[warm radish]

another regarding the height-based filters we have

ya. so those are the stencil-like features we have

hopefully that is close enough to what you need/want

you can get some neat combinations by stacking several noises + height filters with the other math filters together

[elfin laurel]

I made a terrain in blender and SLAPPED it into unity how can I make it like an actual terrain I can make trees and grass on?

[oak goblet]

if you cant find a regular solution for the 3d model to terrain, blender can render to a heightmap for a much cleaner pipeline for terrain stuff from blender

atleast, all the stuff ive seen seem to use heightmap

[elfin laurel]

how abouts could I do that?

[oak goblet]

the quick tldr is use this to preview, and in composite directly link "Mist" to output

the rest will be setting up an orthographic camera above the terrain with a size that fits your plane

like so, the camera's Z level lets you adjust where you want the values to lie

less jury rigged, and more accurate methods are possible using other stuff, but this is how i typically do it

[hidden carbon]

Can anyone help me out with importing a texture for my terrain from poly haven?

[slow violet]

Is anyone familiar with this? https://assetstore.unity.com/packages/tools/level-design/intelimap-ai-tilemap-generator-222293#description

I purchased this tools, it works amazingly at what I want it to do. You can generate while the gsme is running and I am trying to generate chunks that aren’t generated within a certain radius of the player. Where should I start so I can achieve this?

[lyric elm]

Hey, i imported a GMOD map into my unity project but the textures are gone. Is there a fix for that?

[quick kite]

Does anyone know how to reduce this edge that's excluded from navmesh?

[oak goblet]

Your navmesh has agent radius, the edges are inset by that

Just gotta check out the navigation window panel

Or the entity component for beta navmesh package

[quick kite]

Perfect! Thanks

[potent birch]

Hey, I am following a tutorial and I am trying to subtract terrain with a brush. Set height to 15 and I can't manage to make it subtract from terrain. Tried for an hour or so, anyone? 🙂

[naive wren]

I was trying to do something similar when I realized my terrain was already set a low elevation. My workaround was to make a neighboring terrain, move it lower then blend both heights with a brush to simulate a beach scene. Now my problem is that there is a value difference between both terrains that's driving me nuts. I'd like to find a solution to keep the terrains a have, but I might just end up scrapping them in favor of a single large terrain.

[hybrid tiger]

Should I remove the black border lines from my tiles? I feel like it looks like a bathroom scene right now

[raw onyx]

can someone help me

my terrain brush is blocky

nvm i fixed lol

[novel granite]

Should be able to move around a scene with wasd right?

[winter minnow]

When you hold right click in scene window, yes

[novel granite]

Yeah, strange.. not working anymore

[novel granite]

figured it out, was zoomed out all the way lol

[verbal nest]

Whenever I click the sand texture, it gives me this error

When I paint the sand texture it's black

This terrain is completely glitched out wtf

I don't get it

Why can it be so hard to just use imported terrain data

Every single little thing goes wrong

Stupid Unity terrain

[lofty oyster]

Hey can someone help me with this issue? So I have this model in unity, and the first picture is what it looks like default, but when I add the moon texture it doesn't really work it just becomes a very tiny bit darker. Why is this happening?

[lofty oyster]

i lowered the polygons a lot too and the texture doesnt work

idk what to do

[shell jolt]

Unity terrain relies(optionally) on the alpha channel of the texture, if there's no alpha channel in it the texture mostly would be be black WITH THE DEFAULT SETUP..

adjust it in the material property of the texture OR just make a proper texture with an alpha channel in it

I reckon there's an option to force add an alpha channel via import settings in 2022.2b... not sure in any other version

Tips!.. You can see this happening by comparing and dragndrop two textures, one with an alpha channel the other one without, you'll see a different property in the material tab of the terrain texture

[verbal nest]

👍

[lucid walrus]

Does unity have 3D Virtual terrain maker in it? If I want to create a game in virtual terrain like The Long Dark.

[warm radish]

@verbal nest for those errors, i think you can get around it by adding a brush filter to the BrushFilter stack in the Terrain Inspector. we've seen a few users encounter these exceptions and that seems to have been an okay workaround for most. sorry you're gettin those. i think we fixed it in a later package version

[tiny tide]

How would I convert a terrain heightmap height to a world position without using TerrainData.GetHeight()?

[verbal nest]

Ah alright, thanks!

[shell jolt]

@warm radish While you're here, and sorry for the ping.. is it possible to inject custom passes to instancedterrain?... I'm all ears for any suggestions, and sadly, the instancedterrain is a must for the project

[normal ginkgo]

Hi all, is there a way using Unity's terrain system to choose a material for details/grass? I have a custom material for the terrain but I don't see an option for the grass anywhere

[civic pivot]

After working on lighting effects for my terrain, the grass and other details are no longer appearing...

It only appears if I turn off "billboard", and then I get this

any ideas what's going on here?

[covert raven]

Anyone know how to set a height map in map magic 2?

[warm radish]

Heya. Can you elaborate on what you mean by custom passes? Ie. what kind of stuff are you wanting to achieve with them

[shell jolt]

Lotta things, but two that we sorta stuck at the moment such as:

1. Normal blending to blend custom mesh into terrain
2. Clouds shadows scrolling on top of the terrain + terrain objects (trees, grasses, etc)

Any direction will be pretty much appreciated on this.. And thanks for replying 🙂

..
Also note, we can do those without InstancedTerrain, ... the blocker here is simply bcos InstancedTerrain won't work with custom passes

[civic pivot]

Still looking to solve this, anyone know?

[ashen pecan]

is a way to pain terrain with mud exacly where tank track will go?

[heavy otter]

bro

i can't see any trees other than the billboards in the distance

[unreal forum]

I have designed a terrain and now I would like to increase its size by adding some clean space around it. When I change the value of terrain width and terrain height, it is resized but everything is stretched and trees are badly placed. Is there a way to simple resize the terrain and preserving the current terrain 'ratio and trees) in center of the new resized terrain ? (I don't want to use terrain neighbours as it introduce additional constraints...)

[idle glacier]

Anybody have experience with Nature Renderer? Just put it onto my terrain and now all my trees are stuck to the camera?

[sour grove]

is there something in the terrain tools package to reconcile edges of tiles? i could have sworn i found something but maybe was imagining it?

[warm radish]

is this because you don't have access to instance ids for the geometry?

[warm radish]

hiya. could you expand on that for me? thanks

[shell jolt]

Simply bcos InstancedTerrain won't allow us to inject our own custom passes

it's mentioned somewhere in the docs too

[warm radish]

hmm ok. i'll see if i can find that

[shell jolt]

See this too https://forum.unity.com/threads/solved-custom-passes-for-unity-terrain.936413/

the staff also already confirmed it there

[warm radish]

ahhhh like hdrp volume custom passes

that's interesting

@shell jolt i'll test it out some time today. ping me if you don't hear back from me

my guess is that both those things you listed might be kind of rough to implement in a fullscreen pass (i haven't tried anything like that beyond simple sdf projections onto the heightmaps so im not sure how mesh blending would look). usually this is done using virtual texturing (VT) and, at least for mesh blending, done when the mesh is rendered with lookups into the terrain VT

clouds may work

that's easier to map from worldPosition.xz to a cloudTexture uv

[shell jolt]

I will and thanks for responding!

Also, I managed to make it work, but it breaks the instancing, which beats the purpose of IntancedTerrain 😄

[warm radish]

ha. how'd you make it work?

[sour grove]

@warm radish oh when you have two edges that dont line up because you've been sculpting etc

[uncut juniper]

Hey everyone,
Is this the right place to ask?

I'm wondering how high quality my PBR textures should be for my terrains. is 1k fine? or should i go the 4k pbrs?

[warm radish]

can you try clicking the reconnect or autoconnect button in the Terrain Settings section in the Inspector window

might also need to make sure the Terrain Tiles line up perfectly on a grid

[warm radish]

i'd start by figuring out how many pixels you want per meter/unity unit on your terrain. from there you can calculate the texture dimensions when factoring in the tiling rate for the terrain layer textures. it largely depends on your art direction and target platforms

[sour grove]

I must have messed up my terrains as they arent reconnecting, but must be my fault(messing around with kind of a dots terrain placeholder scene utility), thanks for pointing that out!

[warm radish]

awesome. glad that worked

[sterile gull]

I have a problem, I'm trying to make a terrain but my material do this

[sterile gull]

The terrain Is all strached

[brave juniper]

Hi I'm a beginner, just want to ask how do I export a terrain from 1 project to another

I tried to export to fbx but it doesn't work

[sterile gull]

Please

nothing, I did it

[slim stag]

I want to move forward and backward in terrain while clicking shift . How to do it

[reef jetty]

has anyone faced the following problem?
while trying to paint objects (with polybrush), the mesh becomes a mess
the terrain is not unity native

[primal condor]

Hello everyone. Yesterday I was working on a scene, don't know where to post this issue, but today I opened my unity project and my whole scene is completely missing? My other scenes are in tacked except this one, which also gave me an error? Is there a way to fix this or do I just have to get a working copy of this scene from my GitHub repository?

[eager charm]

Can the TreePrototype.prefab be a prefab, or only a mesh?

[eager charm]

Is it better, generally, to change the size of a single terrain object, or have multiple terrain objects that are the default size?

[weak token]

in this screenshot, grass in the left side is manually placed as Objects and on the right side is painted on terrain as detail mesh. left one is interacting to the realtime point light, but that detail mesh is not... is there any work around to make it interact with light..?

[weak token]

Alright, Painting grass as Tree mesh solved the issue. I don't know if it's the best or performance friendly way...

[eager charm]

I am trying to bake a NavMesh at runtime. The tutorials and code samples I have found online are outdated, and I can't find it in the Unity docs. Can any of you point me in the right direction?

All the tutorials direct me to create a
public NavMeshSurface surface;
But I can't find NavMeshSurface in the docs and it doesn't come up in the VS.

[violet drift]

Anyone know a good tutorial for procedural generation of prefabs on top of a 3D plane?

Probably using perlin noise

[brazen agate]

How can i smooth this out? The default smooth height doesnt average it out.

[fringe pebble]

Is there any way thaat in "Mass plce trees" it just plces trees in a certain texture?

[inland parcel]

I Have a Object name tree and i do prefab for it and I add it to the trrian And I do this Command to see if I can arrive to tree every thing gimme the name But the tree of the trrian no

Any one Help me?

the name of tree it put it terrain

Becouse i Put the tree with bruch in treeain

[pearl aurora]

how do i make the texture not strech

[stoic thunder]

Fix your UV maps

[pearl aurora]

this is the basic unity cube

how do i fix the uvs

[stoic thunder]

in blender. Unity isnt good for doing texture work, if you want something to look a specific way youre gonna have to make it in blender and import to unity

[mild solar]

Why can't I scale the terrain?

It was made from the model beside through object to terrain asset.

[valid oak]

Are u online? @mild solar

You can click here

And search for weight and hight

You can change it easily

[raven pond]

this is the low poly setting on Gaia terrain. I wonder why it looks so different? i want to achieve the look of the green terrain, it looks smooth.

Both terrains are in my project, but i couldnt find a difference in settings, is it lighting that affects the looks so much`?

one of them sure looks like it has less pixels

Okay, seems to be due to different lighting 🤔

looked alot better when copying the lightning object and settings to my other scene

[shut belfry]

Hey, does anybody know how to make/get good heightmaps (as .raw file) for a desert with dunes, like this: (it looks like voronoi algorithm a bit, xd)

[mental bear]

you mean with procedual generation?

[glossy crag]

when I paint grass with the tree paint tool it's stretched, left grass is painted, right grass is what its supposed to look like (I placed it manually)

[full meadow]

Is there a keybind to resize your terrain brush? Cant seem to find one.

[shut belfry]

Yeah

[shut belfry]

Like, finding a heightmap or creating one, that is tileable and can be used multiple times. That's option 1. Or, we create those dunes through vertex displacement at Start(). But then I need a formula to make those cool looking (like Gerstner waves) desert dunes.

Do you have such a formula, or a way to create procedural heightmaps?

[mental bear]

you have missing normals

[dire glacier]

hello, i am trying to make a game where there is a hotel that is procedurally generated, with each floor being random. i want each floor to be of some kind of different gameobject that links after the previous gameobject that was instantiated/generated (so i can load in floors based on the players location). would anybody have any tips on how a system like this would work?

[shut belfry]

Hey, does anyone know why my terrain is invisible after assigning a different material?

Default Material:

New/Different Material:

[grave basalt]

are you sure that the new materiel is compatible with the terrain?

not all materials are

[shut belfry]

It isn't. That is the problem.

[shut belfry]

How can I make it compatible then?

[worn barn]

is there a way to make terrain automatically spawn grass in a 3d game?

[stable lichen]

you are saying this looks bad 😭

[shut belfry]

Wut?

[stable lichen]

you said it looks more like a voronoi algo

[shut belfry]

WELL, for me it does

[stable lichen]

But how did you even make this voronoi texture looking desert? Procedural? or by reading heingmap to set heights of vertex?

[deep cradle]

Hi! How can i get sharp edges between 2 different textures? Or at least not so blur.
Maybe with some mask for brush, but i dont know which and how to use.
Can you please advise me?

[wide karma]

i wanna make an automaterial, that below is rock, and on top it's grass, and it makes it alone without me having to paint it, is it possible?

[frozen heron]

I've tried to look online and couldn't find anything. How do set the terrain color as just a plane color? I want everything to be a rgb green color

[molten bluff]

Hey Terrain Folks

i've one question

Is there any way to Seperate Grass mesh as prefabs from a terrain?

cz, Im gonna convert the terrain to mesh... after converting it No trees or grass exist...So I gotta separate those things at beginning.... is there any way?

[fading compass]

Maybe someone here can help with my problem. I made a terrain and everything was working but now I have huge fps drops and idk why. As you can see at the Images when I look at the water my fps drops from 150 to something around 30 fps but if I then look at the landscape (which is way bigger) I get like around 150 fps. And this doesnt make any sense to me, maybe someone know a soultion? Left side of the third picture is the landscape and right side is when I look at the water. That makes 0 sense

[molten bluff]

check your scripts

it's not problem with terrain rather scripts

try to find out the bottleneck

[fading compass]

I dont have Scripts, I use visual Scripting

[austere flower]

when i duplicate the track and move the red line, it goes off track

Hi, at some angles my terrain doesn't load. How can I fix this?

[heady dove]

Hello guys. I just started with Unity and I was handed dwg files to work on. Is there, by any chance any way to import those file into unity without spending a dollars ? Many people suggested me to use Pixyz plugin, which require a license. Thanks

[true anvil]

Hi guys, I'm still having somthing to lern in unity,
Why is my Grass texture on terrain looks so weird comparing to the one entered ?
The texture resolution is 1024x512 and returns something like a 128 pixels ?

[twin gulch]

Do you guys have any solution for this? As you can see, the spotlight rotates to show the light up on the bush on the right. I also adjusted the Terrain Settings and got no luck.

[true anvil]

@twin gulchI already got it in one of my projects, If i remember well it's related to the bounding box of the object, like ocluders for camera.. But i don't remember how to solve it

[twin gulch]

Hmm, I'll try to fiddle around and get it fixed. Lol @true anvil

@true anvil Can you explain more about the bounding box, please? I tried to look it up but couldn't find more info.

[true anvil]

@twin gulch Bounding boxes are the limits in which an objects is taking place (x min,x max, Y min/max, Z min/max)

if the ray of light detect the edge of the bouding oxe of the object it's start activating it

but in that case, it can also be relative to the shader and the mesh + normals (many way to have bugs)

[twin gulch]

Thank you for the reply! I believe it has to do with the shader. I'll look into that for sure.

[elder star]

How do I import textures and apply them to my terrain?

[twilit terrace]

Hi, why does this happen?

[elder star]

No clue

[potent seal]

Hi guys, whenever I create a terrain in the latest version of unity 2021.3, then select the terrain, it uses all the memory in my system trying to display the inspector (I have 64GB...) - Has anyone else experienced this problem? Note that I also experienced this in 2022.2. Could it have to do with the Terrain Tools package?

[shut belfry]

Can someone help me with a terrain shader, that isn't compatible? (When building, the terrain is simply pink)

I simply done a shader for it and the assigned material under terrain settings is marked as incompatible. (When building, terrain is pink). So how can I fix that?

[faint stag]

Heyy
Why trees placed by terrain tool are... You see?
The prefab can be seem on right

[tall marsh]

why is it doing this when rotating a cylinder?

[winter minnow]

Parent object is non-uniformly scaled

[tall marsh]

Oh what the. Thank you i didnt notice that

[tall marsh]

Wait how do i fix that

[winter minnow]

Reset the scale of the parent object's transform
If you must scale it, do it equally in all dimensions and note that transform values will be inherited down the hierarchy

[potent chasm]

When working with 2D Tilemaps for terrain where you have many terrain types (water, grass, dirt, desert, etc., etc.), do folks generally construct sprites for every possible transition from one terrain type to another? Or do you use layers of terrains (multiple Tilemaps)? Or?

[verbal nest]

Why can't I smooth my terrain properly? I have the exact same terrain settings in Unity URP (the one in the pic is in HDRP) and it smooths perfectly. Here you can see lots of jagged edges. I set the terrain smooth tool at the maximum strength, no change at all

Wtf

I also get this at the shore

I didn't get this in URP

which had the exact same settings for the terrain

around 6x6km

[thorny swift]

I'd say adjust your terrain height closest to your highest point on the map, as it can create jagged edges as there might not be enough depth in heightmap. Also making one "Big" terrain is not best practice as there is a maximum subdivision one terrain can have, splitting it will ease memory and give you more quality at close distance.

[verbal nest]

I already split it into 16 parts and 64 seems like overkill. How would I go about adjusting the height of the entire terrain though?

[thorny swift]

If you sculped the terrain inside Unity I have no idea sorry. If you have Heightmaps you'd want to simply remap them and then change terrain height accordingly.

[wheat remnant]

Hey guys, not 100% terrain related, but this was the most accurate channel to ask this in

i am using polybrush with URP, and whenever i modify a model that has a custom material on it, it turns black, i tried using the shader from the examples, but it still does it
also tried flooding the texture, but that does nothing either, how could i fix this issue?

[wheat remnant]

• only happens when i use a custom mesh, with the built in ones it works fine

[jade whale]

I'm making a small open world game, with the world being an identical copy of my city.
What would be the best & fastest way to achieve this?

[undone lark]

Best and fastest way? Make it yourself from scratch.

[wanton harbor]

so I was trying to paint and I could not get unity to paint correctly as it forced a square brush, also the terrain assumed weird shapes like the one seen above in the picture, The triangle form even though I am using the smooth tool to smooth the terrain using the circle brush. This just started today and unsure on how to fix.

also there is this weird shadow covering the textures.

[timid ember]

No matter how simple the grass texture, it always has this very distracting outline that isn't in the file. Any tips?

[winter minnow]

This usually happens when the transparent area of the texture is filled with a white color, so it bleeds onto the visible area

Checking "alpha is transparency" attempts to spread out the color to eliminate this

But if you have a white fringe on the visible area of the grass, that won't work

[timid ember]

There is no white color, and that is already checked

[winter minnow]

Totally sure? It looks like a textbook case of alpha fringing

[delicate karma]

im using perlin noise for random terrain generation, how do i generate structures and stuff randomly, my game is top down 2d. I cant find any good tutorials for this specific problem online either

[verbal nest]

Best and fastest way would be to ask an expert model and texture artist to make an entire city for you, though it might cost a few thousand $ depending on how detailed and how big your city is.

[verbal nest]

I'd just make a lot of variants of structures instead of making a program that generates custom structures (which seems pretty hard to do), then just place all of those variants at random positions

[jade whale]

I want to do it myself, especially since most of it are just rectangles with windows that can be copy pasted. Though i need some ideas on making it accurate, the layout and sizing, perhaps taking some google maps view or something idk yet

[delicate karma]

is there a way to make a prefab or something and place it in the game?

like i make a structure with my sprites and put it into a prefab

and place that in certain biomes

[ancient lynx]

Hi, sorry if im interrupting, but i'm getting a strange bug with some of my tree textures where parts of the leaves are fully illuminated even in total darkness, anyone know how to fix this?

[cinder sluice]

Hey all, I'm playing around with Terrains and splatmaps (importing) but I'm running into a weird issue. The temporary textures that I'm assigning are appearing semi transparent and I can seem to figure out why. Would anyone have any idea what's happening?

Using HDRP, Imported Splatmap has a solid white Alpha, and textures (solid colours at the moment) have no alpha. Little bit confused as to what's going on. 😕

Screenshot included.

((Texture layer texture settings))

[cinder sluice]

Anyone have any ideas? Banging my head on my desk atm. lol.

[potent chasm]

I have a really dumb question. Will there be a huge difference in performance if the camera is looking at an entire 128x128 TileMap made of 32x32 Tiles compared to 16x16 Tiles? Is it more about the contents of the textures? EG, if the entire TileMap uses one Tile repeated and that Tile has a texture that is one solid color vs every pixel being a different color? Does the number of different textures matter more?

[rose sentinel]

anyone know why my grass textures on this terrain are showing a little line on top? I opened the png files and there is nothing on the image up there :/

[indigo rivet]

How would one go about authoring a world like this:

I feel like, placing each individual rock by hand, moving it around, etc, gets really annoying/tedious. There must be an easier way?

[rose sentinel]

you're in the right channel. You can use terrain to paint the rocks/trees/shrubs/details.

just turn brush size up or down, and opacity up or down.

That waterfall and rock wall would need to be done by hand though.

[indigo rivet]

Thats what I figured in terms of rocks, that still seems like a lot of work no? Painting the ground etc is the easy part I assume, especially with the terrarian.

[rose sentinel]

it's definitely a lot of work, and why a game like Skyrim is absolutely Herculean 🙂

[indigo rivet]

I just feel like, somewhere some how, someones made an easier solution to this lol

[rose sentinel]

well you could use procedural generation or spawners

[indigo rivet]

Sort of what I was thinking as well? But not too sure aout going about it.

[rose sentinel]

would be more of a code approach; not sure how to do it with terrain tools and scripting, I think that would be even more complex. I'd use a script that places prefabs. I actually do this already but it's really specific to my use case

[rose sentinel]

Hello so i want to start working on the terrain but need some advice/tips
my game will be a third person linear adventure in URP
so how would i go about creating the actual levels keeping in mind optimization for example how big would a single terrain be in width x height so that i don't fall into problems later trying to optimize
Any tips to start on would be greatly appreciated

gonna use Pro builder and poly brush to prototype

[tepid elm]

Is it better to use unity's terrain system, or import a terrain model from blender?

[undone lark]

If you use Unity, then you can edit it, paint textures and things like trees onto it, all from within the editor.

[cinder sluice]

I have a question about the myriad of Terrain systems available for Unity. Is there one (that works in HDRP) that will let you use a Black and White Mask image to determine where a texture layer goes? I build my terrains in Quadspinner Gaea and can build the whole thing in there including the masks and export them etc.

I've tried 'converting' said exported layers into an RGBA splat map, and using that in Unity (I have a splatmap replacement script that works really well), but the surface texture(s) always come out semi transparent on the terrain.

It seems really weird that this isn't a 'thing' tbh. lol.

[manic saddle]

Any idea if it's possible to disable shadow casted by terrain details ? I wish my grass (painted with details brush) wouldn't cast shadow but my other props would

[open yacht]

any tips for building open world games in terms of terrain?

i am wondering how to manage terrain chunks, do i activate the terrains manually around the user, or do i just use culling?

for example, let's say i have a quadrant of 3 by 3, then i can activate just the surrounding terrain tiles around the player:

is this the approach to take? or are there others? i have searched everything i could on the internet, there seems to be a lack of information in this area

[open yacht]

also, can anyone suggest any good terrain tutorials?

[tepid elm]

Not related to unity's terrain system, but Sebastian Lauge's channel has some good terrain videos

[open yacht]

Thank you, I have went over his tutorials. Great resource for those who want to make procedural worlds. I am searching for more artistic craftsmanship of terrain.

Does someone know how to change terrain tree culling when the camera is very close to the tree?
Basically, im walking past some trees and i can see them disappear when walking past them.
Is it a mesh pivot thing? Collider thing?

[cinder sluice]

@robust vale It might be your Camera near clipping plane?

[robust vale]

My near is alreaty at 0,01

also, the whole tree mesh disappears at once. Not just being sliced/ cut off by the near plane

[cinder sluice]

Aah okay, sorry, misunderstood. Yeah I've had this before a while ago, iirc it's because the pivot point (or maybe the collider?) goes out of view of the camera so it registers the object 'out of view', I'm sorry but I can't remember how I fixed it. 😕

how can I light my indoor scene with ambient light? Currently the walls are blocking the light when baking the GI

ideally i need the light to pass into the room but not out of the room

essentially its just a box

Hello, I have a terrain that has a lot of steep inclines and the textures get stretched on those areas. I read up on a technique call triplanar mapping but I'm kind of lost on where/how to apply it. https://gamedevelopment.tutsplus.com/articles/use-tri-planar-texture-mapping-for-better-terrain--gamedev-13821 This resource says to put it in a fragment shader but I have no idea which asset i should be accessing the frag shader on. The texture? Or do i have to make materials for all my textures

[desert pendant]

I'm interested in the same thing. As a workaround I use this shader: https://imgur.com/gallery/M2ZkPFE

This one could be interesting too: https://cyangamedev.wordpress.com/2020/01/28/worldspace-uvs-triplanar-mapping/

[raw pawn]

Thanks for the resources, i’ll check em out!

[tawdry pumice]

Hello unity crashes when painting details, i dont know what those errors mean. I have tried other meshes, some without textures. And other unity versions

[tawdry pumice]

How do i fix?

[cinder sluice]

Is it possible to change the material of a terrain in c# ? Had a poke around but can't seem to find anything (using a custom materal/shader, but generating the terrain at runtime)

Ok, nm, took a shot in the dark and seemed to have worked. lol.

terrain.materialTemplate = [custom material];

[desert pendant]

Hi dudes.
Is there a way to use materials in textures layers instead of image textures? I have procedural textures made with shader graph, and I want to apply them to a terrain texture layer. Is it possible?

[cinder sluice]

iirc the only way to do it is with a new Material, you can't plug materials into the texture layers directly.

[desert pendant]

So I have to write a new shader that takes in account terrain texture painting and apply the material I want depending on the texture painted?

[digital steeple]

Anyone worked with SetHeights before? for some reason when I call it from further away from origin (0,0), it gets offset/loses accuracy biased towards the origin point, anyone know why that happens?

Another possible relation regarding that is: if the heightmap is accessed by integers, arnt we losing accuracy for values between it? in unity 0.5 is a huge difference

[digital steeple]

fixed it 👍

need to consider heightmapscale as well

anyone knows any good material pack for making a simple 2d game

Terrain tools stops working when i delete terrain data

i have multiple terrains so why is it null referencing the terrain i deleted the data for

oh never mind i deleted the terrain data but forgot to delete the terrain itself that's why

[ripe cradle]

anyone able to help? My trees aren't placing for some reason so is there an issue with my settings here?

ok turns out I just needed to restart unity some sort of bug. God I hate the terrain tools.

speaking of which, does anyone know WHY despite me having tree height set to 2, regardless of what I do the trees height will not budge. meanwhile the billboard seems to scale just fine?

anyone able to help would be a godsend right now I'm losing my mind over how simple this should be ☮️

[ripe cradle]

ok well an hour later no resolution found to the above issue but a new one has arose 💀
it seems that I can only actually make the tree work as a prefab if the prefab only contains one meshrenderer component in the prefabs main parents game object. any fixes?

[ripe cradle]

Hello. I made the tree into a single mesh in blender and combined the textures to get this weird graphical bug when using it as a tree. Can anyone tell me what is actually happening here? Also, despite "random rotation" being turned on the trees are all facing the exact same direction for no reason. Does anyone have any terrain tool alternatives they could refer me to? The official terrain tools are pretty awful and I'm really ready to move on at this point.

I just want something that is simple and works with the low poly style I'm going for.

[next kayak]

Go to terrain settings, there has to be a setting like 'billboard distance', increase it

Hi! Not sure if this is the right place to ask questions about using Houdini with Unity?
Wondering if anyone else has run into licensing issues (i got an indie license). I keep getting this error:

`Loading Asset Library From File : HAPI Error: No Valid Licenses Found

• To install license(s) see https://www.sidefx.com/faq/question/how-do-i-license-houdini/.
• HAPI_LICENSE_MODE unset or is set to 'default' meaning Houdini Engine will first try to acquire a Houdini Engine license and if one is not found it will try to acquire an interactive Houdini license (Houdini Core then Houdini FX).
• No Houdini Engine Indie license found.`

[copper jolt]

Why is my terrain texture so fuzzy

Its not sharp

Anyone know what setting to use to fix this?

[rose sentinel]

Is there a way to include the detail meshes into the terrain heightmap? For example, if I paint a bunch of 1x1x1 cubes onto a flat terrain, there should be a bunch of height=0.5f on the heightmap

If there's a way to do this with trees, that would be great as well

[autumn spire]

Very quick quedtion. If I don't put in a Plane, will the player just fall when booting up the game?

[winter minnow]

@fickle blaze Games that use the voxel style don't do it by duplicating cubes
They start with voxel data generated from a noise algorithm or with a voxel editor that only has data points
Then the engine (whether game engine or voxel editor) interpret that data into gameplay objects / geometry and draw the cube faces for the voxels only where they will be visible

In Blender you can get something similar with the "blocks" type remesh
You'll notice there's no internal geometry generated at all

And if you want to use blender to make voxel-style environments that's the modifier I recommend to use for it

A similar effect with more options can be made using geometry nodes but you need to be adept with that system for it

[winter minnow]

Even if you're hand crafting one level, I'd still use a voxel modifier for it
You can place the blocks by hand but that seems tremendously inefficient

[winter minnow]

This happens because the mesh is non-manifold, meaning the back faces are exposed because it's not solid

[rose sentinel]

Is the Terrain Tree feature only meant to be used for tree vegetation, or can it be used to paint rocks, boulders, and other objects?

[full dust]

With a 3D environment built using marching cubes; is it possible to have Unity allow the player to alter (dig / raise) the terrain, in real time?

If not; what are the alternatives aside from voxels?

[winter minnow]

Unity has no marching cube system, but if you make or find one then supporting realtime modification is definitely within the realm of possibility
I think the default Terrain's heightmap can be modified at runtime, though there could be performance costs associated with updating the collider

All shapes of meshes can be modified at runtime if you know how
I think there are some modifiable terrain assets on the store which use neither voxels or height maps

[full dust]

Thanks, that makes things a lot clearer for me.

Is there a way to use Unity Terrain Trees with URP? all my trees lie flat

ive tried rotating the object in blender every different way possible and they still lie flat

do i need to switch from URP to the built in pipeline?

or switch to Unreal

[undone lark]

Unreal, that's the only logical solution. Clearly all Unity games making use of terrain trees are a lie.

[shell jolt]

you can't just rotate the object and export, you need to apply the transform in Blender everything you changed something related to Transformation in object-mode

hit ctrl+a select All transform

[last linden]

Its not like all your problems are gonna be fixed switching; every engine has their fair share of problems

although i'm not sure what you're saying by they are flat i personally never had this problem

hi, is there a way to change the light layer of the terrain grass? (urp)

[polar zodiac]

say I have a terrain that has length/width 256, detail resolution 512, and detail resolution per patch of 32. what is the full resolution of the terrain? like if I wanted to use SetHeights with a 2d float array, what should the length and width of that float array be?

[void briar]

i hate terrain so much, alphamap and heightmap dont match up and it makes no sense and is so poorly documented

i dont think i will ever be succesful at making games, i cant seem to use terrain properly at all

why is the alphamap width 512 but the terrain is 4000

the terrain is 8 times larger than the alphamap because its not Monday

try again on Monday

i use software thats been deprecated for 20 years that has better documentation than Unity

back then documentation was a thing. now its like a game

ill just try every single part of the API and one of them should be the one i need

Hey, I am trying to help a friend I work with. He uses Terraland 3 and has built a real world area. his tiles are 10km by 5kmHe has placed assets himself (Buildings Trees etc). He now wants to use the same terrain for mobile where the Hardware is not as powerful. Rather then build the whole terrain (50km+ with assets) again. He is wondering if he can split the terrain tiles up. So they are maybe 5km by 5km so that the tiles needed to be rendered are smaller hence less demanding on the Android devices / hardware.

Any idea or help would be much apricated.

Hi everyone does anyone have any experience with custom terrain shaders ? i'm trying to write very simple shader for debug purpose that simply renders a single texture on the entire terrain. and i've not been successfull yet.
I've managed to write a tool that write information to a texture,
and i would like to display that texture on the terrain for readability purposes

i must say i tried to use a surface shader but the terrain was full on glitchy

Anyone ever run into artifacts when adding more than one paint details objects? When I only use one detail object such as a grass object everything works fine, if I add a second grass object then I get a white outline artifact on all my 3d grass.

[faint trench]

Hi would anyone want to join a game developer and work with him to create the map, I will share more details if u are interested please

The game is called War Of The Worlds

based on the 2005 movie

[thin ibex]

an exciting opportunity for anyone interested to take part in a copyright infringement

[faint trench]

not exactly

we dont want the exact layout of the map

and the idea of the game is inspired by the movie

and he has been developing the game for a year and a half with millions of views

no copyrights from paramount so far

the developer will pay accordingly to the skills and quality u have for maps

I hope im not breaking any rules, admins. wanted to give someone an opportunity to join a game developer

[velvet quiver]

how can I make that water look more natural like draw mode better

[thorny swift]

smooth it out a bit or use meshes on sides, or make triplanar terrain shader

Making the brush bigger so that it smoothes upper and lower part also makes the uvs unstreched its certainly the easiest to do

[jolly storm]

hello, how's that my character always play falling animation over the terrain collider?

it's okay with mesh collider tho

[winter minnow]

Layers are usually used by character controllers to distinguish walkable terrain
Although I don't think a layerless object is possible, that field of your Terrain is empty so make sure it has a correct layer

[jolly storm]

I'm pretty new to this. I'm trying to figure what layers are in terms of my character there. basically it's just a free third person asset

This field

If that's not the problem then it might be that the problem occurs because of the slope

I have a pre-HDRP terrain that uses billboards for grass. When I upgrade to HDRP, which no longer supports billboards for grass, do I have to repaint the terrain?

Just wanted to make sure there was no alternative before I started deleting things. Thanks!

I am having issues with terrain generation.
Each chunk generates a 16x16 terrain
The parameter heightmapResolution is auto set to 33. Looking it up you can only set it up to a power of 2 + 1, I tried it setting it to 17 or 65 which satisfy the condition but they don't change. I set
I tried setting it before and after I create the size array but it always stays at 33.
chunkSize is 16 so 17 should work even thought it doesnt mention it needs to be power of 2 + 1,
Even looking at the decombiled source code of unity it doesnt show any restrains at power of 2.

Basic terrain with details added - I updated one of the fbx files... and every detail on the terrain just vanished. How do I recover?

I've even tried reverting (svn) the rock fbx files and the terrain.asset file and restarting Unity.
Please tell me I didn't just lose all of my terrain details...

Okay, I did another revert on the whole dir (removing new files, too) - got my details back. Still not sure what happened, but... at least I didn't just lose all the details.

[proper ice]

Hey peoples, Im running into a bug with Unity terrain, the platform im using for my work in using Unity 2019.4.31f Upon increasing the size of my Unity terrain my brush size also increases to 10 or higher and i cannot change it back to 1. I found a Forum online where B_Campbell from Unity disclosed that the issue was fixed in Terrain 4.0 but in the version im using highest i can go it 3.0.1. Mr Campbell posted a script that supposedly will fix the issue for earlier versions but it doesnt seem to work anymore. Has anyone else experienced this issue and if so what is the remedy

B_Campbell posted a "Fix" on the Forum here but the script given doesnt seem to work https://forum.unity.com/threads/terrain-tools-texture-brush-size-is-stuck.1042396/

[drifting crown]

Did you try restarting Unity?

[proper ice]

I have and restarting my pc, the issue persists even in new projects

[drifting crown]

Try resetting layout. It affects a lot of things like gizmo settings etc.

[proper ice]

Ive reset layout, deleting libraries, removing the 5x folder but seems to have not fixed it

[drifting crown]

If this data saved with the terrain it wouldn't help

You could export terrain data, create a new one and import just the terrain mesh

and texture

[proper ice]

i havent even began scultping the terrain yet because this issue occured. Ive tried adding a new terrain to the scene.

even in a new project with no imports this issue exists

even typing in 1 and hitting enter for both jitter and size just puts it back at these numbers

[drifting crown]

Ah, so it saves somewhere in Unity Editor settings?

Might have to dig out those and nuke them

[proper ice]

I dont even know where id look for that. On the forum a staff posted a script that should reset the values but it doesnt seem to do anything at all

and i know the script is in the right place because its showing up in Tools

[drifting crown]

Just checking, you did run the script in the editor menu it created?

[proper ice]

correct, I created an Editor Folder in Assets and it then appeared in Tools

[drifting crown]

Try restarting after this

Command suggests that those settings are kept in the registry and it clears everything there

[proper ice]

will do, ill update you when i do.

After restarting it sets the brush size to 100 and the lowest it can go is 16 still

[drifting crown]

Try setting specific values then yourself, like this post explains. https://forum.unity.com/threads/terrain-tools-texture-brush-size-is-stuck.1042396/#post-7594771
If that doesn't help forums might be best bet.

I'm having an issue with terrainData.SetAlphaMaps(). I generate a terrain from my editor scripts, including splat maps. And in the end I call SetAlphaMaps, it shows correctly, but the moment I press Ctrl+Save the alpha maps are gone from both memory and terrain data

Do splat maps require some special mark dirty or something?

Or when I hit Play. They're working right after I generate, and then when I hit play the splat maps are gone

I'm doing this ```cs
terrainData.SetAlphamaps(0, 0, alphamapData);

AssetDatabase.CreateAsset(terrainData, terrainPath);

[cerulean ocean]

I'm trying to convert Prefab Gameobjects within my level to Unity's Terrain Tree system, keeping their locations within the world. Anyone know how to do this?

[shell jolt]

@cerulean ocean
should be straightforward enough
Note, that this will zeroed your terrainData's treeInstances. So backup your terrainData first. IMPORTANT!

  var terDat = myTerrain.terrainData;
  var newInstances = new List<TreeInstance>();

  foreach (var tree in my placedTrees) 
  {
    //World to UV pos conversion
    var worldPos = Vector3.Scale(tree.position, terDat.size) + myTerrain.transform.position;
    
    //Replace "myGameObject" with your already placed trees (nested loop this)
    var go = Instantiate (tree, worldPos, Quaternion.identity);
    
    var nuInstance  = new TreeInstance{//Fill the properties here. Make sure the prototype already added before this!}    
    newInstance.Add(nuInstance);
  }

  terDat.treeInstances = newInstances.ToArray ();
```\

you'd want to add each unique object as a prototype before you're doing the above.

to add new treePrototype you need to create new TreePrototype then assign your prefab/object to it -> https://docs.unity3d.com/ScriptReference/TreePrototype.html

Typed this directly on my browser, not tested, but you should get the idea

[cerulean ocean]

Thanks, I will try this now (I've been trying ChatGPT's attempt and its not working lol)

[cerulean ocean]

Have you used this code before, and can confirm that it works?

[shell jolt]

remember BACKUP first! as this will destroy all your treeInstance (if any)

I did this a lot so yeah, and as said, I typed this on my browser and its sorta pseudo-ish

and it's your job to test it, not me 🙂

[proper warren]

Sooo

[knotty bramble]

@proper warren

first youll have to make a new layer plaette

then you need to add layers

[proper warren]

Aright

[knotty bramble]

you can select the texture you want

think of it like the earth, how it has different layers

[proper warren]

mhmmmmmmmmmmmmm

[knotty bramble]

basically like this

the one on the top

is what you can see

[proper warren]

aright

What does that help me with tho?

[knotty bramble]

well you want to paint your terrain no?

[proper warren]

How would I use different layers together?

[knotty bramble]

for example if you have different biomes

[proper warren]

Ohh I see

[knotty bramble]

you wont have to do extra stuff

you can just paint it with a snow texture for example

[proper warren]

So layers are bassically just textures for terrain?

[knotty bramble]

yes

[proper warren]

Yepp

I understand now

Thank you!

Have a good day

[knotty bramble]

ur welcome

[rough onyx]

I asked this in main but figured I actually should have here since it has to do with terrain, I have a terrain tilemap that works properly when I paint on default layer. I create a background tile map and instead of using the image from my tilemap it just create a black space where the sprite should be, anyone have this issue before?

[knotty bramble]

It sounds like the background tilemap may not be properly configured. Make sure the tilemap has the correct Tile Palette assigned and that the tiles in the palette have a Sprite assigned to them. You may also want to check that the Tilemap Renderer component on the background tilemap GameObject is properly configured with the correct Material and Sorting Layer settings. If the issue persists, try creating a new background tilemap and repeating the process to see if the issue is specific to that tilemap.

[rough onyx]

sweet thanks I'll mess around with that

[forest granite]

alright because it seems like answers.unity.com is entirely dead currently I'll ask here 😅

Got an issue with importing a blender model into unity and then using it in the tree paint option. It's being painted in side-ways. Yes the model has been rotated in such a way that it's stood upright in unity, if I manually drop it into the scene it's perfectly fine. It is just sideways if painted with the terrain tool

it's also not randomising the height/width of the model either

[amber stirrup]

How do you set trees/detail meshes to rotate to the normals of the terrain? All my ferns facing upwards on a slope looks weird

[opaque rover]

I don't know if it's too late to reply but that's because of blender's shitty system where Z is up instead of Y

you need to open blender and manually turn the model sideways such that Y point above it

then apply rotation (ctrl + a - rotation) to make it the default

[uncut shore]

Hi I made a Object in Blender but if I put it into unity its very small. How can I change that in blender that it is instantly big?

[torn olive]

By scaling it?

Also why are you asking in terrain

[uncut shore]

dont know were to ask

[uncut shore]

If I Scale it in blender it doesent work

[lean phoenix]

Hello! I am wondering if there is a built in or at least a package that lets you paint terrain with voxels (3D cubes)?

[torn olive]

Did you apply the scale? And did you re-export and then re-import it

[uncut shore]

apply the scale? How should I dont apply it

[forest granite]

I've done that, it still paints rotated in. If I manually drop in the asset into the scene its perfectly upright.

I've tried all kinds of ways of rotating it and nothing is changing anything when I paint it in

[opaque rover]

Are you sure you applied the scale? Because that is exactly something that would happen if you didn't

when you place the asset into the scene, what are the transform rotations?

of the asset

[forest granite]

When placing it manually its changing with how I change the rotation in blender, so it is setting it.

I've tried all kinds of settings, -90x in blender sets it to be upright when manually placed in unity.

I am not currently at my pc so I can't give screenshots

[opaque rover]

no

I'm asking

when you drag it into the scene in unity

what does it say about its rotation?

is it 0 for all transforms? Or 90 somewhere?

[torn olive]

To apply the scale, select the object, hit Ctrl +A and then hit apply scale and rotation

[forest granite]

0 for all if I change nothing in blender. If I change it to -90x in blender then it goes to -180x in unity and goes upright

[opaque rover]

that doesn't make sense

how can it be 0, 0, 0 in both and when you change to -90 in blender, it's -180 in unity

[forest granite]

I don't know

nothing with it is making any sense

[opaque rover]

I often use blender to export then import to unity

I've faced the same problem

but I know how to fix it

can you show me a screenshot within unity

of the object placed manually on terrain

with its components

[forest granite]

I will later once I get back to my pc

[forest granite]

@opaque rover ok after booting up the PC it's slightly different, still same outcome though of painting being sideways regardless.
Numbers:

[opaque rover]

Right. Now select the mesh in blender, CTRL + A and do rotation and scale

and then export and import again into unity

[opaque rover]

That's not possible

[forest granite]

I only did what you asked

[opaque rover]

OK but that's rly not possible lol 😄

[forest granite]

from the screenshots I gave, changed nothing from those, hit ctrl+a, rotation and scale, exported and imported it again

[opaque rover]

if you did apply scale and rotation, then all should be 0 in unity

unless your export settings are screwed up for some reason

[forest granite]

it was 0,0,0 in unity before, and then doing it your way put it back to being -180 again

[opaque rover]

but it would also make the scale 1 as it should be

scale can mess up the positioning too

terrain trees always try to spawn with 1 scale and 0 rotation

[forest granite]

the issue though is even if the model is importing as 0,0,0, the terrain painter is painting it sideways regardless

[opaque rover]

read: scale

[forest granite]

It is seemingly spawning them with 1 scale

[opaque rover]

so now presumably it shows 0 for all in blender and 1 for scale? It should after applying the scales and rotations

[forest granite]

no it shows these?

[opaque rover]

then you didn't apply scale and rotation

when you do ctrl + a and all that

it resets everything to 0 in blender as well

[forest granite]

ah now it's all 0's

[opaque rover]

there you go

NOW you did it

and now it should work

or did you already do it and just didn't check?

[forest granite]

I mean it's halfway there

(that's manually placing it)

[opaque rover]

lol

is Y vector pointing up in blender?

that's another problem with blender

[forest granite]

?

[opaque rover]

when you select the transform tool in blender, does the green arrow point above the tree?

[forest granite]

also looks like painting is painting it upwards. Just a bit sunken into the ground lol

[forest granite]

uhhhh green arrow?

OH

[opaque rover]

the Y vector arrow

[forest granite]

uh, yes?

[opaque rover]

yeah ok that's right

so what happens when you try to paint the tree now

[forest granite]

They're upright, just in the ground

It is ignoring the height and width options though in the painter, but I could also just not be understanding those options? (first time using this tool)

[opaque rover]

I think I know why that is

because the origin of the tree is at the circle that you screenshotted from blender

that's what the game thinks is the start of the tree

you need to change the origin point to the bottom

[forest granite]

very dumb question, how do you apply that change?

[opaque rover]

It's not dumb, blender is just unnecessarily complicated

[forest granite]

yeah I'm a coder/designer, visuals I am learning more and more are really not my forte 😅

[opaque rover]

so I'm speaking from memory because I'm not in blender rn (in fact, I'm in unity making my game!)

so you need to select the tree, go into edit mode, select a vertex on the bottom of the tree

then something like mesh - snap cursor to selection

then after that go back into object mode and then something like set origin - origin to cursor

speaking from memory but I think it's pretty accurate

[forest granite]

Well it changed the origin point, but they're still being painted in the same way

[opaque rover]

did you export and import again?

and replace the asset in the paint trees section

[forest granite]

Yup

[opaque rover]

and when you place a tree manually and then select it, you can see where the origin point is...where is it?

[forest granite]

wait, how do you see the origin point?

[opaque rover]

Where the transform vectors are

the little square in between the arrows

that's where the origin is

is it at the bottom or in the middle

where the vectors cross

[forest granite]

ahh

yeah it's still in the middle

[opaque rover]

yea then you didn't do it right

go back, re read what I said

try again

[forest granite]

I mean I've followed what you've said now 5 times

[opaque rover]

when you look at the picture of the tree that you sent me from blender, you can see two circles actually

one is the one with the red/white stripes

and one is the one in the center of the transforms

both need to be at the base of the tree if you did this correctly

if the transform circle is still in the middle, then you just snapped the cursor (red/white) to the bottom but didn't set origin there

[forest granite]

This is the option I'm using

[opaque rover]

yeah that's good

but the one before that

OK look I'll try and clip it for you

[forest granite]

Yes I am moving the cursor before choosing that option

the cursor is moving to the location I want it to be

[opaque rover]

I just clipped a vid for you just in case

[opaque rover]

yes that is right

https://streamable.com/bmk438

I uploaded this but I guess you don't need it

[opaque rover]

try applying location, rotation and scale again (ctrl+a)

then export and import again

[forest granite]

that just did this

and then it's still the same in unity

[opaque rover]

change it back then but it should work

that's the problem 100%

I know cause I've been doing it too

and it works for me

if your origin is at the bottom, that's where you object starts and that's how it should be placed upon terrain

[forest granite]

then ctrl+a again?

[opaque rover]

just snap it back again with the same method or undo

or just set origin to cursor again

but that should be that, you shouldn't have problems again

[forest granite]

It's still not showing the changed origin in unity 😅

I even clicked the "set origin to 3d cursor" button multiple times just to really make sure it was set lol

blender

unity

wait

it's working

[opaque rover]

what changed?

[forest granite]

literally nothing

just apparently manually placing it just, doesn't work

[opaque rover]

you didn't delete that tree in the screenshot, right? Is it still the old one

[forest granite]

nope that's a brand new tree

[opaque rover]

wtf

that shouldn't happen either but

hey

if you need to place manually, you can just rotate and move it at will

as long as terrain painting works, it's good, right?

[forest granite]

should these work how I think they should work? randomly change those values?

[forest granite]

tbh yeah, I can deal with manual needing some tweaking, I just don't want to manually place a whole forest lmfao

[opaque rover]

They should but I find that they often don't idk why

some terrain tools are weird for me too

btw that grey capsule is a slider

you can slide the left part and right part as range

to, you know, edit the possible variation in height

then try if it works

[forest granite]

Yeah I gathered that, but default doesn't seem to be doing anything at all for that model at least, everything's the exact same height

though rip tbh if that's just a funky part of the tool for everyone. I can deal with copy-pasted trees at this stage and that'll be a future me problem xD

if I add enough tree variation and some fog and low light that'll cover it up enough, right? lmao

[opaque rover]

yea it didn't work for me either idk

I mean

at worst, open blender, resize the tree and save it as a different model

then add that one in as well

[forest granite]

That seems like an incredibly obvious solution and yet I somehow didn't think of that lmao thank you

[opaque rover]

yeah no prob just keep working

You will have a billion questions during your experience but you will learn, and one by one, you will solve all of the problems

[forest granite]

Normally I just stick to my code corner, but my partner on this project is also just a coder/designer so neither of us know much about the visual side of things haha

[opaque rover]

What are you guys building

[forest granite]

A semi-horror open world puzzle exploration game based around sailing. Travel to different islands, solve puzzles on each island, upgrade the ship with things you find, solve the mystery plaguing the isles :3

[opaque rover]

Cool

[forest granite]

(we don't quite have a consise explanation yet lol it's not at the stage of being out to the public atm)

[opaque rover]

good luck

[forest granite]

thanks 😄

[opaque rover]

my next project will be a horror game

[forest granite]

horror's a fun genre to make for honestly

can have a lot of fun playing with all different kinds of horror

[opaque rover]

yeah for sure

I will enjoy the level design, graphics and atmosphere there for sure

[thorn hemlock]

Hey guys, I have a best-practice question. I am quite new to terrain design. I have experience with blender. Can I use Blender to create the entire terrain (with trees and wind animations and such) and import it as one or is it a better practice to create all trees in seperate assets and place them into Unity?

[shell tangle]

Does anybody know why is the texture so blury , its just solid color

and does anybody know how to add colliders to trees???

[shell tangle]

its kinda bad

[civic trail]

I'm really confused by vegetation studio's terrain texture settings, I have added custom textures but the default ones keep showing:

[lyric violet]

hey so can i paint actual full textures, color and everything, onto terrain?
example: rocky terrain. i paint a grass texture on it to.. well.. add grass.

[lean mauve]

Why my terrain is metalic, but i dont add terrain metalic texture

[torpid scarab]

making tilesets is brain damaging

[unreal forum]

Hello in the Editor the grass of my terrain is not displayed until my camera is very near of the grass. I have tried to increase the Detail Distance, Billboard start, ... no effect, it can just reduce the distance, not increase it. Any idea how to solve this problem ?

[unreal forum]

It seems that is linked to anisotropic textures

[winter minnow]

They're more complex than they look, and Unity's tools aren't really great

[torpid scarab]

take ages to make one only for it to end up horrible and redo again

and the amount of file naming you have to do... I just start spamming my keyboard kaps lol

[stuck knot]

have you find a solution? i have the same problem with trees

they just dont render above a certain distance

[full rain]

is it possible to use a mesh as a terrain thing? Like if I already had a mesh that was just a flat plane or a flat cricle, and I wanted to use that as terrain?

[unreal forum]

As I saied, for me it is a problem about anisotropic texture. In the menu Edit -> Project Settings -> Quality If I set the Anisotropic Texture to "Forced On" then is solve the problem. But that eats too much FPS to me.

[stuck knot]

i guess that makes sense since its possibly a render thing

[unreal forum]

You have another parameters to change the trees distance (in terrain settings). Do you try to change them ?

[stuck knot]

the trees distance?

do you mean tree density and brush size?

[unreal forum]

Tree & Detail Objects: "Tree distance" and "Billboard Start"

[stuck knot]

oh

i will check that when i get home

[stuck knot]

thx

[rose sentinel]

I'm having some trouble with the terrain tools in Unity. First, The grass I brush with the terrain tools are not using the angle of the terrain they are on

This makes them stick out of the side of a small incline, making me place grass manually on complex terrain

Second, i'm not very satisfied with the default terrain tools, in that the UI and control I have is not as great as third party tools, like Vegetation Studio. The only issue is that the game i'm importing this map into removes C# scripts, so I can't use other tools, are there ways to extend the functionality of the Unity terrain tools?

[heavy matrix]

Hello guys, is there any tool (preferably free/cheap) that can be used to pain objects that are not terrains? So like the terrain brush but for a terrain made in let's say blender.

[opaque rover]

Common problem. Metallic is in alpha for terrain textures, there's no separate metallic slider. Google for the oslution

[unreal forum]

Hello, I'm trying to create a golf game. I'm using Unity terrain to design the terrain. Now I need to add the ball "hole". The problem is about the terrain resolution, I cannot create a very small hole. So I have designed something like this. A large plate to cover a big terran hole with a small hole inside. It works pretty well except for the ball physics. The junction between the plate and the terrain is not perfect so, sometime, when the ball rolls on the terrain, there is a collision between the ball rigidbody and a plate edge. Do you have any idea to solve this problem or another way to create a small hole in a Unity terrain ?

[tame river]

I'm getting this error with my terrain ```cs
MissingReferenceException: The object of type 'Material' has been destroyed but you are still trying to access it.
Your script should either check if it is null or you should not destroy the object.

[lean sand]

Is it possible to make the terrain's polygons shade flat or unsmoothed like make it "low poly style" while still having the option to edit it with the terrain editor? or is the only custom low poly terrain has to be imported from some 3rd party software ?

[tame river]

also when will this be a thing

[pliant furnace]

@next jewel

1. Use level of detail (LOD) systems: LOD systems can help reduce the number of polygons and draw calls required to render trees in a scene. You can use Unity's LODGroup component to switch to lower-poly models as the camera moves further away from the trees. This can significantly improve performance while still maintaining the appearance of a densely packed forest.

2. Use instancing: Instancing is a technique that allows you to render multiple instances of the same model with a single draw call. You can use Unity's GPU Instancing feature to render large numbers of trees without a significant performance impact. This technique works best if you are using the same model for all of your trees.

3. Use billboarding: Billboarding is a technique that involves rendering a 2D sprite that always faces the camera. You can use billboarding to render trees as flat planes with a tree texture on them. This can help reduce the number of polygons required to render trees and can significantly improve performance. However, billboarding may not work well if you need to see trees from different angles.

4. Use culling: Culling involves only rendering objects that are visible to the camera. You can use Unity's Occlusion Culling feature to prevent rendering trees that are behind other objects or not visible to the camera. This can help reduce the number of draw calls required to render trees and can improve performance.

5. Use a combination of the above techniques: You can use a combination of LOD, instancing, billboarding, and culling to optimize the performance of your forest scene. For example, you can use LOD and instancing for close-up trees and billboarding for trees that are far away. You can also use culling to prevent rendering trees that are behind other objects.

In addition to these techniques, you may also want to experiment with the number and size of trees in your scene. Adding too many trees or using large tree models can significantly impact performance. You can use Unity's profiler to measure the performance impact of your forest scene and make adjustments as needed.\

[tame river]

How can I make grass like trees where I can just mass generate them instead of using a brush?

[torpid scarab]

ai generates and terrain don't mix together

[stone flax]

hey, I hope I'm in the right place here
I Have a problem, I want to make interactable terrain, so I have a tree prefab, which I can punch and it get's destroyed, if I place it manually everything works fine, but if I use the tree painting tool, so I can work more effecient, nothing works anymore

part of my code : ```csharp
private void OnTriggerEnter(Collider other) {
if(other.gameObject != null) Debug.Log(other.gameObject);
}

if I place the tree manually it logs Tree1, like it should, but if I paint the terrain it Logs jsut Terrain, which doesn't really make sense, since the trees are having their own colliders

Hope I'm not in the wrong channel for it

not seeing what I'm doing wrong here

[torn olive]

Nothing. Afaik, this is expected behaviour

[stone flax]

What do I have to do different then? I want to interact with every tree, stone or whatever I'm going to add in the future. Doing it manually would be painfull tho

[torn olive]

Dont do it manually but idk how to automate it sorry

I mean i can think of some ways

But its complicated

[stone flax]

For the moment I have a script which randomly spawn the trees, it would be nicer to paint them tho, to make a really nice looking scene

[torn olive]

Try googling for interactable trees with unity terrain or something like that

[stone flax]

Tried that allready somehow I can't find much, eventho this should be a common issue based on how many survival games exist, they must have faced something similar

The only things you can finde are 8-10years old

I'm losing my mind on this project I will just create an editor script with a small circle which paints for me

[stone flax]

okay I found a different solution it is really stupid, you have to replace the terrain trees on runtime with the prefab ones

https://forum.unity.com/threads/solved-placing-trees-with-scripts-on-terrain.462885/
the solution

[chilly roost]

Is it possible to use terrain detail mesh painting tool and have my prefab object keep its original shader material?

[lofty shell]

why are all my assets not converting?

[torn olive]

oh boy

these assets you are using all have their own custom shaders, meaning that they have to have a specific version of that shader written for the SRP you are trying to upgrade too. If you want those assets to work, they either need to have a shader written also for URP (ideal), or (not recommended if you know nothing about shaders) you need to convert the existing ones to URP compatible

@lofty shell

[lofty shell]

oh okay thanks

[stark nexus]

Anyone know why navmesh doesn’t seem to work with trees?

[shell jolt]

it should work.. try to keep the layer.. there's a toggle to keep tree instance's layers

[hushed seal]

Hi, I want to ask, if is there some way to paint my terrain only with colour and no texture. Thanks for response.

[somber sun]

Anyone familiar with procedural tile generation?

[lofty shell]

i made a terrain then i found out my trees dont have colliders. i added colliders to the tree prefab but they still dont have them. do i have to replant them all?

[lilac coral]

I recently managed to fix that. I opened the file path of the tree and added a capsule collider to the tree and it worked. You have to be in the prefab

[lofty shell]

Yeah I fixed it but why only capsule collider why doesn’t mesh collider work

[lilac coral]

No idea. It's not like you're gonna pick leaves from the tree? 😂

[lofty shell]

I mean yeah but my tree is a bit curved so it collides weird

[lilac coral]

Add more capsules manually. I am not sure why u can't add mesh collider my friend

Btw have you got any grass on your terrain?

[lofty shell]

Yeah

[lilac coral]

Does your grass sway like the wind is blowing hard?

Or is it nice and stable?

[lofty shell]

Stable

[lilac coral]

Do you know how to fix that?

Mine is swaying a lot

[lofty shell]

No I’m really new to terrain, I don’t even know why it’s swinging since I didn’t add any wind zones

[lilac coral]

Mine doesn't have any wind. Atleast I don't think so lol.. I just imported the grass texture from the asset store and painted it over the terrain

[lofty shell]

Same

[lilac coral]

Could u please link me the assets you're using?

for the grass

[lofty shell]

I don’t have the link now but low Polly fantasy

Free

[lilac coral]

Wow! Your world is beautiful 😍

I think I know which one u mean, thanks!

[lofty shell]

Thanks I’m going for that anime look

[lilac coral]

Very nice! Good luck, and sorry for not figuring it out for ya

[lofty shell]

It’s called stylized assets that look

[lilac coral]

Nice, ty mate!

[lofty shell]

So if you want those low Polly stuff then type stylizied before

Polytope studio

That’s the asset creator

So you can find by that

[lilac coral]

I'm more into realistic terrain, but i'll probably use that grass and modify it hehe

[lofty shell]

Okay

I find that realistic stuff is hard to make look pretty

Because you need to add more details and stuff

[lilac coral]

Yeah that's true

Hey, I'm wondering what the best way is for making terrain such as this (specifically the shorelines)

I need the terrain to be raised slightly, with a rocky substrate (without stretching the textures)

I already have a solution for the waves and water, though the terrain is my main issue currently, and I don't feel like spending 50+ $ on a tool that can do this for me, seeing as I've already spent more than enough money on things

[eager monolith]

I have made the leafs children. how do I make the children also come with it?

[rose sentinel]

Hello, I have this problem, do I have like a gloss on my terrain? I don't know what it's called, but here's a screenshot -

[meager radish]

i might figure out a solution for this, can u go to the material u use for the terrain

change the shader to Nature>terrain>specular

u can attune the glossiness in this way, it might work, idk

[rose sentinel]

Thank you very much, you have been a great help 🙂

[copper bramble]

Hi 🙂 I have a probably newbish question. But im using a building that was build in Blender. Now if i dont want the players to be able to go through the walls. do i have to add separate box coliders to each?
Or can i use coding? Maybe through rigidbody? or through tags?

Was wondering how other people usually do that
Dont really know how to phrase a proper question for youtube or google though 😄

[upbeat arch]

Usually a building that the player can walk through is made up of multiple game objects representing walls, doors, windows, floors, etc, each object with its own collider. If the building is not meant to be walked through, consider a large collider that encompasses the entire building. If your building is one object, you can try a mesh collider (may not be performant in some cases) or use grayboxing / blockout and then during runtime, either set the mesh renderer to disable on the graybox elements or set them to a layer that doesn't render on the player camera, which will leave the colliders in place.

https://www.blog.radiator.debacle.us/2017/09/how-to-graybox-blockout-3d-video-game.html
https://www.youtube.com/watch?v=SZ2iC6pFbV4

Rigidbody is used mainly for physics and you want to use those only where you need them and sparingly since they're not performant in a lot of situations. Tags are mainly used to identify particular gameobjects in code for certain situations where layers aren't appropriate.

[copper bramble]

thank you so much! also thanks for the links, will check them out! 🙂

[upbeat arch]

You can try the terrain tools package, it might help define some of the more detailed terrain you're looking for. Unity released a package of new tools back in 2019, that to be fair, is decent. Detailed terrain is something that Unity has struggled with that has often led to better solutions through expensive 3rd party apps like Gaia and CTS. Dynamic detailed 4K design is something that (sadly) Unreal does better than Unity without adding asset store add-ons. If your camera is going to be anywhere near the terrain (< 50f) you want to use 4K stamps for your terrain and 4K materials/textures. Your best bet for doing this yourself is the Unity Terrain tools package. I don't know if they've kept it updated for the many render pipelines or compatibility with other packages, but it's worth a shot. I tried it myself a few years ago and the results were decent. https://www.youtube.com/watch?v=aExdxF4OKBo

[stuck grove]

How can I add a coalition to a "terrain" because the capsule or the model is going down

[rapid urchin]

Does anyone have a good way to place a bunch of prefabs (trees, bushes, grass) 2D? I wanna do terrain without coding it if possible.

[tepid sand]

can anyone explain why im flying through terrain?

[winter minnow]

Why wouldn't you be?

This may sound like a silly question but both are what you need to ask yourself

By that I mean verify that you have collisions between the ship and the ground
Just disable everything besides the rigidbody and colliders and let gravity drop the ship down
It should not fall through

If it doesn't, that means that most likely the method you're using for movement is ignoring colliders

is it possible to make different physics materials apply to different floor textures?
all I can work out how to do is apply 1 single physic material to the entire terrain
please ping if you respond because i might forget to check

Hey guys, I am fairly new to unity and absolutely have no idea where to start with doing my terrain for a 3d isometric game.

I heared that it boils down to unity's terrain system vs "meshes", whatever that might be. And I know that there's a thing such as a nav mesh that can make AI characters navigate through the terrain.
Where do I best start reading?

I can work with blender (I just started, but I finished my first character with animations today), as well

How many tiles does your game have per map?

[sturdy veldt]

What does this entail? and how do i fix it? x)

[solar swan]

Set all textures used in the detail assets to the same format (automatic or rgba) and make them all share the same compression setting (normal, high)

[sturdy veldt]

im sad to report that it didnt work

oh hang on, now it did

what

i changed it back to its original settings and now it works o.O

[scarlet pagoda]

magik

[sturdy veldt]

i did have the inspector locked. maybe that caused the issue

i couldnt use the brush, but now i can. Allthough the warning is still there :>

[solar swan]

maybe click on the "read more" link

[zealous gull]

What exactly do you mean by "tiles"? I won't have levels, it's supposed to be a single map (like open world)

[solar swan]

basically how big is the map and what kind of resolution are you aiming for? usually a map, even in a non-tile-based game is somewhat made up of a base grid to help with placement of objects/alignment and for performance, i'm asking how many such grids points are in your map, AAA games typically have 0.5 to 0.25 meters for for human scale games and less the further away the camera typically is from the player

if your game has elevation changes, in what way are they gameplay relevant and how steep are they?

[zealous gull]

I'm not sure if I can answer all these questions, since I'm just starting out. It's a game with an isometric perspective, so I'm not aiming for very steep elevation changes

It's not tile based as 2d platformers, for example, often are. So far, I've just tried out the terrain tools and painted some ridges on grass, so I'm not quite far yet 😛

I am aiming for some forrest areas, with some rivers, a few hills, maybe some smaller steep elevations with rocks, think of 10 meters max

[solar swan]

based on that its hard to shay what is better for your project.

[zealous gull]

Ok, sorry for not being able to provide you with more precise info. But I am aiming for low poly graphics and models. So I think there is no method vastly superior for my project over the other, right?
To give you a hint, check out Len's Island on Steam. I am aiming for a similar graphics quality / resolution / camera angle & distance

[wanton ember]

for some reason when I use the place trees feature the leaves on the tree aren't there.
(this is a urp project)

[clever mantle]

hi, i'm new at working on terrain, is there a way to import faster all the details/trees instead of adding one at the time?

[shy narwhal]

Try out different YT tuts. They tell cool tricks while creating. Also google and ChatGPT mate.

[dense vector]

can someone tell me what the error means?

this is what the model import (from blender) looks like

[copper bramble]

Hey everyone 🙂
I hope you have a good Monday!

I am still struggling to find out how to make these walls not walk through. As of right now i just have box that you can see on the first picture as a playable character. The box however can just walk throuugh the walls etc.

The Building ive imported von blender. How do i make the walls solid? I tried a box collider but as you can see in the secon picture its just big box around the room so the player is standing already within the collider.

what is the best technique to go about this?

I was thinking of working with tags? But i dont know

I tried Mesh Colliders now and it seems to be working. I am just wondering if that is the best option or if it will slow things down a lot?

[rigid junco]

Did you assign an actual prefab and does the prefab have a renderer?

[thorn timber]

I made a custom terrain shader but it stopped working when I imported the terrain tools package can anyone ehelp ?

[dense vector]

ah, seems like there was some strange script messing it up, it's fixed now.

can someone tell me why my trees are rotation 90 so that they are sleeping on the ground? additionally, there are no leaves.

the tree object by default is lying on the ground, so it should be rotation: x = -90. but how can that be done for trees generated using the terrain tools?

[shell jolt]

you should look up the origin of your tree

if you're in blender press ctrl+a and select position/rotation/scale whenever you moved or changed something

then check the apply transform when exporting

[dense vector]

where can i find the apply transform option? i just save the file and then drag it into the unity assets folder

[shell jolt]

right when you click export to fbx or whatever file you chooose

scroll down and you'll see it

or just google it

[dense vector]

ok

[agile imp]

Hello
I'm about to create a game, where the half of the map is going to be a falt city and the other half hills. Whats better? Create only a terrain, or a terrain for hills and a basic plane for the city?

[torn olive]

I think terrains are far more performance heavy so probably skip the terrain for the city

[buoyant bone]

@dense vector not sure if you fixed it or not but try this

[reef jetty]

hi folks,

am I missing something or doesn't the vertex color indeed work with the terrain?
I'm trying to use the vertex color as a way to mask two layers, but I don't even see the brush icon appear upon trying to paint on the terrain

the shader setup is simple

I'm using unity 2020.3.7

[winter minnow]

You mean Terrain terrain? I don't think that uses vertex color at all

Rather splatmap textures

[reef jetty]

are there any other terrains I don't know about? 😅
saw this video and wanted to try it out, no success eventually
https://www.youtube.com/watch?v=bA9BXvYfaB0

[reef jetty]

the drawback of the splatmaps is that they are no dynamic, so to say
they need to be redrawn in another software upon changing the terrain

[winter minnow]

This is a generic terrain made of a plane, which you can vertex paint on just like any mesh
The Terrain component is a highly specific type of procedural geometry, it probably doesn't even store vertex color

[reef jetty]

looks like this )
thank you for your help! I've found a workaround if anyone's interested

[sonic light]

does anyone know why my stones arent rendered correctly? I have to walk very close for that

[fierce pilot]

Maybe try increasing your detail distance

[quartz wyvern]

Is it possible to make a mask work for unity?

This is an example of my mask

I want to be able to use this but dont know how to in unity

So far tutorials havent been guiding me the right way at all

Im just trying to make a floating island and i dont know what to do

[coarse axle]

this is annoying

why this- what, what is this

help

[stray rivet]

Hello! Does anyone know why my scene canera doesn't render any billboard grass?

It was fine a while ago and I don't know why it became like this

[serene echo]

Im trying to use the terrain to generate trees and when I add a prefab of a tree this pops up even tho the prefab has a mesh render
Image

I made the tree using the probuilder idk if that makes a difference

[solar swan]

Could be, pro builder by default doesn’t create an asset, which I suppose you need for terrain rendering. You can export your pro builder mesh as asset

[sonic light]

Is there a way of putting a object far away from the character (for example a plane in the sky) and get it rendered without increasing the far clip plane of the camera? Or do i have to create a custom skybox and add the object into that?

[wooden shoal]

Ok so im having a problem, when i do texture painting if i ever paint onto another terrain with the same mats and layers, it creates a new layer then proceeds to paint using one of my other layers. is this a bug?

[serene echo]

im placing tree down but they have a short render distance. is there any way to up the distance?

[jagged ferry]

Hey guys, i'm trying to bake a navmesh on my terrain. The problem is that it ignores completely the trees on the terrain (left) but the ones i've placed manually are perfect (right)

Anyone know a solution for this?

[torn olive]

https://answers.unity.com/questions/1876528/navmesh-not-working-with-terrain-trees.html try this @jagged ferry

first reply

[white flume]

Hey, I modeled a low poly world in Cinema4d (only flat grass, Mountains etc. without any Trees). So I bake the gamemap and exported it as a .fbx file. I would like to paint my Assets (Prefabs) in Unity so I dont have to place them all by hand. For this i have to shape/convert my "gamemap.fbx" somehow into a Terrain so I could use the terrain brush tool. Is there any way to get this right this way or are there better options? feel free to add & pm me, I really need help to get this 3D map done properly.

[jagged ferry]

Does not work. Ended up finding a script that placed colliders on all the trees then baked

[keen falcon]

hello guys

im new using 3d design

and i wanna learn blender can someone recommend me some good curse or video tutorial pls ?

[torn olive]

Wrong channel and just search blender donut tutorial and use the latest one

[lime oyster]

how can I make grass intract with coliders unity 3d? Do someone have a tutorial or something? I use unity terrain system

[torn olive]

How do you make a good looking tree? there are a lot of assets that seem to have really good trees including relatively well done leaves and insanely good looking bark, is it simple to achieve similar, because all of the tree assets ive seen so far have bugs or messy rendering... not sure how to make such a good tree though

[solar swan]

basically,

• use speedtree together with some texture/atlas library like quixel megascans (for leaves/branch/bark/details) to make a tree model and corresponding UV map (check out speedtree's yt tutorials to be amazed at what you can do), speedtree has tools to quickly extrude a few branches, spawn quads for leaves and mask/map atlas textures of leaves/branges into them for a nice looking tree model (this is what they call the realtime-workflow)
• in unity make or use a proper vegetation shader (TVE, Nature Shader, etc.) to get all the fancy features like subsurface scattering, wind sway & flutter, seasons and interactivity like fire/damage/disease etc.
• typically if you have vegetation assets from different sources you need to do a bunch of conforming to make them render right with your chosen shader and style, this often involves modifying stuff like normals and vertex colors on the model, and also with speedtree this takes some experimentation, but its not too difficult

[lime scarab]

what is the best way to procedurally generate terrain? So far ive looked at height maps and noise algorithms, as a newbie I don't want to start off by using the worst one.'

[summer oar]

U could look at brackeys he has some nice video about it

What kind of game do you want to make , like how do you want to use procedural generation

[lime scarab]

im aiming to make a survival game sort of like Lens Island, as Im new to making terrain I want to start out with procedural generation for the landscape and placing other assets like trees and plants, etc.

[summer oar]

Okk 👍

Perlin noise method is the popular one

But I heard something called Wave function collapse method to generate procedural world . Some youtuber showcased it

I feel it's a new way to create it . It's hard tho

[solar swan]

"the best" way, as in "how does AAA do it?" is called World Machine (app) and World Creator (app), if you mean procedurally at runtime, noise, obviously, but that doesn't help much without tools to give you control, so you would look at some assets like Map Magic or make your own, if you mean procedurally in the Unity Editor, then Microverse (asset) would be your top choice. Typically a real game with a procedural map would still need a lot of control over the world generation, so a typical approach would be to create certain terrain modules manually and blend those together in a semi-random way.

[torn olive]

isnt quixel megascans UE-only unless you feed them money

[solar swan]

if you're looking for free stuff you won't get far when it comes to art

[torn olive]

that is fair

how do i make my own megascans lol

[pale canyon]

Quick question. So I'm practicing making terrains in unity and i started putting down grass when i noticed how low the draw distance is for foliage. I went into terrain settings and made the detail distance 250. This still seems to be crazy low. Any way of increasing it more or am i missing something? also please talk to me like im 2 please because im new to all this haha

[solar swan]

go to a forest with a hatchet and a black cloth (or blue or green), chop some branches off trees, spread out the cloth, put the branches on the cloth, take photos, tweak them in photoshop to make them seamless tiles (bark) and atlases (for leaves), for 3D: https://www.youtube.com/watch?v=fFy-muKWmQ8

[torn olive]

alright

[lime scarab]

are u talking about taking very basic assets, and making many assets with those, then randomly placing them to create the terrain? assets would be like small rocks, boulders, different types of rock formations, cliffs, etc.

[lime scarab]

why is my height map png just a white square? I went to https://heightmap.skydark.pl/ and chose a spot, and downloaded the height map png and put it in my assets. then when I apply it to the terrain object its just a white square, shows the same in the files?

figured it out, I think I was just choosing bad spots xD

[twilit wedge]

Hey all, I have a (pretty basic) terrain problem that I can't seem to solve with google. I am trying to create a new terrain beside an existing one and have them mesh well into eachother. However, when I create a new terrain right now.... see attached screenshot

[solar swan]

well, the 2nd one is empty, you need to paint something on it

and make sure they are actually linked (reconnect button) or use the "add neighbours" feature

[twilit wedge]

The second terrain seems to be much lower than teh first terrain (makes sense, the first terrain starts at y=100) and the second terrain doesn't even seem to allow drawimng

[twilit wedge]

Seems like it's all fixed somehow!

[lime scarab]

uhm... anyone seen this one before?

Crazy textures xD

[spiral garden]

Sure. It's incompatible/broken shaders.

[magic cove]

do anyone know how to solve this probmel?

[winter minnow]

What problem exactly
I wonder if you intended to ping a hundred thousand people for this question

[magic cove]

I, want to make the lines between the two texture more smooth and not so jaggy
