ah that would be cool indeed, especially if it could be combined with some density map (just single color/alpha) for defining how much it would spawn random things if you need to tweak the amount manually etc
warm radish
@real coyote it's pretty much the same as doing 2D. main difference from 2D, where you are calculating the gradient for a 2D square, is that you are calculating the gradient function for a cube. That means you are going from 4 points for the square to 8 points for the cube.
if you have the terrains tools package downloaded, i have code there for different types of 3d noise. i'll also post some of it here but in the terrain tools package, the files you'd want to look at are in
YourProjectsLibraryFolder/PackageCache/com.unity.terrain-tools/Shaders/NoiseLib/Implementation
here's the 2d perlin function
/*=========================================================================
2D Noise
=========================================================================*/
float get_noise_Perlin( float2 p )
{
float2 i = floor( p );
float2 f = frac( p );
float2 u = quintic( f );
/*=====================================================================
c(0,1) d(1,1)
_____________
| |
| |
| |
| |
|____________|
a(0,0) b(1,0)
=====================================================================*/
float2 a = hash( i + float2( 0.0, 0.0 ) );
float2 b = hash( i + float2( 1.0, 0.0 ) );
float2 c = hash( i + float2( 0.0, 1.0 ) );
float2 d = hash( i + float2( 1.0, 1.0 ) );
float ga = dot( a, f - float2( 0.0, 0.0 ) );
float gb = dot( b, f - float2( 1.0, 0.0 ) );
float gc = dot( c, f - float2( 0.0, 1.0 ) );
float gd = dot( d, f - float2( 1.0, 1.0 ) );
return remap( lerp( lerp( ga, gb, u.x ), // lerp along bottom edge of cell
lerp( gc, gd, u.x ), // lerp along top edge of cell
u.y ).xxxx, // lerp between top and bottom edges
-1, 1, 0, 1 ).x;
}
a, b, c, d are the calculated points of the 2D grid cell ( the square ) that position p can be found in
you can think of a,b,c,d as vectors now
ga, gb, gc, gd are the gradients for vectors a,b,c,d and the offset vectors from inside the cell
to take a step back, here would be the 1d perlin noise:
/*=========================================================================
1D Noise
=========================================================================*/
float get_noise_Perlin( float p )
{
float i = floor( p );
float f = frac( p );
float u = quintic( f );
/*=====================================================================
a(0) b(1)
_____________
x-axis
=====================================================================*/
float a = hash( i + 0.0 );
float b = hash( i + 1.0 );
float ga = a * ( f - 0.0 );
float gb = b * ( f - 1.0 );
return remap( lerp( ga, gb, u ).xxxx, -1, 1, 0, 1).x;
}
reason i am providing the 1d and 2d approaches is to try to show how that might extrapolate to higher dimensions. sorry if this is all redundant information
this is all in hlsl btw. im not sure if you needed gpu or cpu-based noise. should be pretty much the same
and here is the hash function that i use to get pseudo-random values from each 2D cell
float2 hash( float2 p )
{
float x = dot( p, float2( 165.244, 492.128 ) );
float y = dot( p, float2( 382.763, 234.567 ) );
return -1 + 2 * frac( sin( float2( x, y ) ) * 98102.5453123 );
}
In 2D you have one set of 4 points that define your grid cell. In 3D you now have 8 points to define it, giving you a cube. Here's the cube:
/*=====================================================================
c2(0,1,1) d2(1,1,1)
______________
/| /|
c1(0,1,0) / |d1(1,1,0) / |
/____|________/ |
| | | |
| |_ _ _ _|_ _ _|
| / a2(0,0,1) / b2(1,0,1)
| / | /
|____________|/
a1(0,0,0) b1(1,0,0)
=====================================================================*/
you can do the same 2D calcs twice, because what you really have is two sets of 4 points that make up two 2d grid cells which are then offset from each other along the vector perpendicular to their plane
you do the the 2D calcs for the 2d cell that is made up of points a1, b1, c1, d1 and then do the calcs for the 2d cell that is made up of points a2, b2, c2, d2
then interpolate between those values based on the third component (z) of the quintic interpolated offset for the point within the cell, u
@real coyote try working with that. let me know if i need to clarify anything. im not giving the answer outright in case you wanted to try solving it for yourself but if you want me to just provide the rest of the 3d implementation, let me know and i will be happy to do that
also, for anyone else, if i have messed up my explanation and understanding of the implementation, feel free to chime in as well

Is it possible to downgrade a 2019 terrain to 2017 easily?
desert sun
@worn oriole why?
worn oriole
Been working on a project for someone that uses a terrain built in World Creator 2, and its main export function can only import into 2019.2+
Need to downgrade so it functions with VRChat, cause the devs of that are terrible at ever updating their Unity version
desert sun
oh VRChat...
probably you can export Heightmap from 2019 by using Terrain Tools from package manager

@warm radish not to get to semantic, but that’s gradient noise not perlin. Gradient noise is not as nice as perlin, but faster to compute, so it tends to be used in shaders more.

2019.3 terrain filters ... is there any complete guides for it

Anyone know if there's a way to use Tilemap 2D in Unity to place 3D objects instead? Or at least something equivalent? I tried using MAST but it's pretty buggy.
glass mortar
did you check 2dextras?
peak magnet
Because curves is really bad for filters they should have used values like world creator does

@autumn rover Im pretty sure they have a prefab brush
which could be used for 2d OR 3D
autumn rover
Aha! Thank you @glass mortar
peak magnet
Who started to work with terrain system 2019.3
autumn rover
@glass mortar I looked into it yesterday but it seems like the prefab brush are only made to randomly add in prefabs, have you worked with it in the past?
peak magnet
hi does anyone know the lastest unity 2019.3 terrain ?
craggy granite
instead of asking random questions, better to just ask the thing you are wondering about @peak magnet
like, the actual question
peak magnet
@craggy granite when i ask
a real question ... people ignore me
when i try to turn around to see if there is active people i got a random awnser ty next time read my first question lol
kiugetskiHier à 14:52
2019.3 terrain filters ... is there any complete guides for it
so avoid sending random awners if you do not take the time to read 7 lines higher
if i could find a complete guide i would not have asked anything
the question cant be more serious then that
the only guide from unity is totally incomplete about the terrain system 2019.3 no explanation about the filter curve system or nothing so instead im trying every combinasons until i find what curve does what and im getting there
craggy granite
you'll not find "complete" guides for everything
have you checked the official docs? (check the pinned messages on this channel)
I always go to them as my first step, instead of finding some random online tutorial - which will be outdated anyway
peak magnet
all i want to know is how the curves work on the filters because on unity docs they do not talk about terrain filters
formal zephyr
In my game, I have multiple square sectors of terrain next to each other. When the player clicks on one (I already have click detection set up), I want the game to highlight the piece of terrain in some way.
In the picture above, inside the Unity Editor it outlines the piece of terrain you have selected; I want an effect similar to this in game. I am fine with an outline, or the entire piece of terrain highlighted/colorized; What is the simplest way to get a highlight effect on a terrain GameObject? (It won't let me place materials on it)
(I already have references to the selected piece of terrain, I just need to apply the visual effect!)
formal zephyr
Does anyone have any ideas on how to easily colorize / Add a material to an entire piece of terrain?

Is there any word on Terrain HDRP Grass? Debating whether to start making my own grass system or not.. I just don't see a point if there's a hint of grass coming out soon. Yeah I know I can use SpeedTree grass - which i've been doing. It's just extremely inefficient and slower to work with as I gotta start handling LOD adjustments just for the scene camera only.

Hey there :) I am using Unity 2019.3 HDRP and Terrain Tools 3.0.1. In this scene I use a terrain and a large cube for my water. The edge looks like some resolution is too low so it looks like snapping to a grid. I tried to change some numbers but nothing worked out, probably some1 here knows a solution.
arctic elm
I was looking at a unity demo and was wondering, does anyone know how this terrain was made? it just doesn't look like anything I could model in unity
the mountains, the plains, the river, it looks like one big piece modeled together, and all is textured properly. I want to know how I can make such terrain myself
rose sentinel
@arctic elm Have you looked at the new Terrain Tools in the package manager? There's erosion brushes and such in it that could get this look you are looking for... However - the cliff area looks like it's probably Tri-Planar mapping.
formal zephyr
Does anyone know a way I can easily color an entire piece of terrain? I want to allow players to select different pieces of terrain, how can I apply a color/material/highlight effect fairly easily?
knotty root
@rose sentinel what is tri-planar mapping?
@formal zephyr 1 my name is michael 2 thomas brush on yt look at his vid about terain
rose sentinel
@knotty root Tri-Planar mapping projects textures onto a mesh from the X,Y and Z axis. This allows you to avoid texture stretching, etc. Shader Graph has some little bit of info you can read up on it. https://docs.unity3d.com/Packages/com.unity.shadergraph@6.9/manual/Triplanar-Node.html
It can be costly though

my brain is 2 small for that

onyx bane
Who do I need to speak to about Speedtree7/8 shaders in URP? Completely unusable in the current release!
https://youtu.be/DCeS1nEcP-w
craggy granite
@onyx bane Unity has had speedtree stuff in some sort of limbo for few years now. someone quickly did the speedtree shaders for LWRP initially and when they started to HDRP version they threw the whole thing back to drawing board in attempt to implement speedtree support in shader graphs instead (which IMO is the right approach)
somehow it's just been going on and on and no actual release
once they get the SG approach merged, you can do whatever graphs with URP and HDRP's lit SG's
at least how I've understood it, they'll just expose additional nodes to process the speedtree data (which is similar to what UE4 does with speedtrees)
onyx bane
@craggy granite I am chasing it up with the developers, reported at (Case 1221827) [URP][Terrain][Speedtree]Terrain LightProbes for Speedtree7/8 shaders bake black
It does seem there are regular changes to the Speedtree source on the SRP Github repository, although in a release version of URP containing them, you would at least expect the behaviour of the tree assets to be more consistent between the Speedtree modeler, the built-in Unity renderer and UniversalRP.
Hopefully they look into it
craggy granite
I really hope they get the SG nodes done because then it really boils down on the regular SG shaders behaving well
there isn't really any major things in speedtrees that should even warrant their own shaders, basically there's color variation and baked wind to feed to vertex offset
onyx bane
You're right, I'm going to probably make my own SG that has some translucency effect and the rest is alpha clipping, normal map and color variation as you say.
It's more for convenience as I am making many different trees, they automatically load up with the new URP/Nature/Speedtree7 shader when imported and materials are generated. So converting all the LOD of the tree's materials to my own is a ball-ache.
That or I can look into writing a custom asset processor with an Editor script to do that when they import... but it is all tied to a 'regenerate materials' button on import of the Speedtree :/
It's unlikely I could get around that bit of the process
Omg there is a Speedtree importer example here! https://docs.unity3d.com/ScriptReference/AssetPostprocessor.html

Smooth the terrain back to flat along the connections and start over works, figured it out.
junior grotto
I've been looking for guidance on how to implement terrain features beyond simple perlin noise height maps, found this excellent exploration of various techniques, thought it might be useful: https://hal.archives-ouvertes.fr/hal-02097510/file/A Review of Digital Terrain Modeling.pdf
delicate needle
@ivory cairn may be a bit late, but couldn't you just create a height map from your model and use that for the terrain?
That should also fix the smoothing I think
ivory cairn
@delicate needle yeah... I tried to do that already but for some reason unities terrain smooths edges no matter what... I’m now dropping the whole terrain idea and Am moving to models
The grass was really the only benefit I noticed with it
Might as well just use poly brush instead :/
warm radish
@ivory cairn there is a mesh stamp tool in our terrain tools package that you might be able to use
ivory cairn
whats the damage
(to my wallet)
oh i just realized you're an admin, I ended up using poly brush which was perfect for the mesh terrain
Once I add post processing, It'll probably look pretty good
warm radish
No damage haha. But glad to know poly brush worked for you
thorny swift
As it is the terrain thing aswell I'll ask here too, is there a way to overwrite the tree light probe anchor?

Anyone know why polybrush breaks when applying to large meshes?
It completely destroys the mesh collider on the mesh and the mesh as well sometimes
Might have to develop my own tool :/
warm radish
in what way does it break?
ivory cairn
First
once i hover over it and the zoom override gets applied
normal
hover with mouse
ivory cairn
is there a limit on how many vertices the mesh can contain? cause I'm really confused
rose sentinel
what is the best site to download high quality texture
quick thicket
@ivory cairn I know this is probably really late and might not be useful at all, but if you have a terrain in blender and all you want is to be able to texture it, paint the parts in which you want stuff like mountains and grass which the corresponding color, then go into paint.net and select everything in a certain color, such as gray for mountain, then import a tile-able rock texture in a new layer covering where the gray would be. This is certainly not the best way but it works for me when I do simple terrain

If I want to create a terrain similar to the one in Marble Madness™ should I use the Unity terrain or would it be better to create just use a load of altered cubes?

devout panther
@craggy granite Why not terrain?
craggy granite
you can't make geometry shapes like in that image using terrain
if you only need smooth slopes, then sure use terrain but you can't make a scene like in your example image with it
devout panther
@craggy granite Probuilder might be the way forward then.
queen tundra
anyone know of a way to add grass to terrain? Last i checked it didn't work in HDRP, but maybe its good now?
vocal pollen
@craggy granite definitely pro builder
@queen tundra no it’s still not working on the detail painter. I believe they are working toward terrain entity conversion and will likely wait for that before getting grass going again. Just speculation, but what I surmised from reading the forums.
queen tundra
is there a decent substitute? It would really kill me to leave a flat grass texture on everything
vocal pollen
I plan in using dots so what I did was create my own detail painter similar to polybrush (but more performant) and creates sub scenes automatically placing the objects inside. The performance with grass and trees as entities is fantastic.
queen tundra
got this thing where my terrain is invisible in editor
i feel like its some little thing but idk how to fix

@queen tundra Brackley has an awesome tutorial on creating grass with a shader. URP & HDRP.
hybrid ginkgo
So does anyone find the built in shader for unity terrain to be waaay under par?
has anyone come up with a solution for this?
We need two things that it just does not provide
High blending and a texture driven roughness

but it only overrides the entire map no way to paint with the unity tools
devout panther
How do I create a Terrain Data asset? i deleted one and need to create a new one but I can't see it on the Create menu.
craggy granite
@hybrid ginkgo you are using the old renderer, right?
I know HDRP and I also think URP has terrain shader that does support height-blending
I'd say... don't expect much improvements for the old renderer as advancements tend to come only for systems they are actively working on
rocky marten
I was curious so I played around with something related in URP.
Sadly, it seems like AO (Green) and Height (Blue) channels on mask map are not doing anything.
https://docs.unity3d.com/Manual/class-TerrainLayer.html
"...
G Ambient Occlusion
B Height
..."
craggy granite
huh
I could swear I saw the PR for making the terrain stuff work similar way to HDRP ages ago
but it's possible it never got merged too
rocky marten
Or maybe it's bugged? The documentation makes it look like it should work the same for URP and HDRP.

@sacred parrot Whatcha struggling with my dude?
I was setting up a semi-large scene recently and found that a "well textured" border is way more effective than just having flat barriers. Having different kinds of barriers, a jagged border, and differences in height all make the border feel natural. So for my scene, I used a horizontal storage tank for a chunk of the barrier, and then a dip in the terrain with a rail around it and pipes at the bottom. On the next side of the scene I used a collection of ladders and stored materials to make an insurmountable obstruction.
I don't know if that helps you, but it's just something I experienced recently 🙂

I've been browsing for a few hours, looking for a voxel based procedural terrain generator.
I found a couple; Ultimate Terrains, Voxeland and Voxel Play.
Any recommendations? And preferably, free?

can anyone help meeeee
fresh valve
@rose sentinel ehm what exactly doesnt work
you have to click here to access the terrain brushes
rose sentinel
@fresh valve I did
But
Whenever I try use that brush on on terrain it doesn't make anything no
No slope or hill or anything
@fresh valve I don't understand why it's not painting on terrain
fresh valve
Hm I can't really help you when I'm not exactly seeing what you're doing and how the program looks when you are doing it. I don't have enough information.
Did you try making a new terrain?

How do I add on a Texture to a material, I only know how to change the color of it
fresh valve
@rose sentinel sorry, i don't know whats the problem, can't help you. 😦
@vestal oasis Every Material has a Shader. A shader is basically the code that determines how the material is rendered and shown on the screen. Your selected shader is most likely one for color only. You have to select a shader that supports textures.
The default shader supports textures though.

You have to click here.

warm radish
@rose sentinel for terrain tiles to be actual "neighbors" as far as the API goes, they have to be the same heightmap (and control map) resolutions
rose sentinel
@warm radish how to do that
warm radish
how do you set them as the same resolution, you mean?
warm radish
@rose sentinel you will have to select each terrain neighbor and set their respective texture resolutions via the Settings tab in the Terrains Inspector
jagged violet
Is there any way of using a shape as a sort of cookie cutter? Like I have a cube and I want there to be a recess in the middle of a cube I'm using as a ground layer to make a lake using the shape of the lake I've already made
Like in DOOM in E1M1 where the courtyard is recessed below the ground plane
I have this so far but I want it so that the green recesses into the cube
and of course if I move the cube up or the green but down, the shapes just clip and there's no recess

@jagged violet are you looking to put a hole in the box the shape of that green thing?

Exactly @upper charm

I'll probably do in in blender, it'd be basically same way you'd emboss text wouldn't it?

Hey everyone,
So I am relatively new to Unity, the last time I used it was back in 2017 where I mostly handled 3D art for a project. I am recently getting back into Unity and learning all there is to learn. I created a custom shader yesterday, and I was wondering if it's possible to apply that custom material/shader to Unity's terrain - or perhaps paint with that custom material.
The shader is beyond a simple albedo + normal map
Also if there's alternative tools that let me paint materials on to terrain meshes I would also like to know about that
any help is appreciated >_<
rose sentinel
Got a pointer saying I should be looking into Custom Terrain Shaders
and mimicing the parameters i have on the shader I made

willow idol
I don't have speedtree and have a budget of €0, are trees made in blender (with LODs etc) viable performance-wise for a first-person game with maps within 1km^2? I'm using URP. Also what shaders are best for trunk and leaves in this case? Thanks
willow idol
actually more importantly, what's the "proper" way to do trees since unity does an arse of a job at handling them as it always did? I used Critias Tree System beforehand but that seems to be well out of date by now. Is it possible to have a forested area without tanking the performance, using URP?
rose sentinel
Is there anyone here that can tell me how I can increase the terrain resolution where when I paint a texture the textures are not seen so blocky
when it paints, it comes out very geometric. Is there anyway I can increase something for it to seem more loose and faded around the edges?
rose sentinel
Anyone?
static field
doesnt that depend on the geometry of the plane you are painting on? aka make the ground you are painting on more subdivided?
upper pasture
You can fix that in how your shader does the blending..
The included unity shader is crap, it just does linear blending. Height blending looks a lot better.

tired sigil
Are there any Terrain Height Blend Shaders that support 8 textures? Everything I see is just 4.
regal ginkgo
No you would likely have to roll your own
Need to be careful when going over 4 textures for terrain with performance as well
tired sigil
I'm sitting at 12 and perf is good, but willing to go down for height blending.
MicroSplat does it, but it's a whole setup - I got it working, but just want the Shader.
regal ginkgo
Yeah you can do it, but I believe you need to adjust your workflow, because the normal limitation is there due to the data for heighblending being stored in the control RGBA, one channel for each texture
Depends what you need, you may be able to create a triplanar heightblended shader alternatively if that gives you enough
tired sigil
I think I found one from Laxer that can handle all of the layers, but it's pulling Height data from the Alpha of each. Might try modifying it to reference a separate map for height..
regal ginkgo
Yeah that's the main issue you need to adjust your workflow, and if you have to change something down the track it could cause a problem and require rework if you don't plan it from the start
The built-in can pull height from a mask in a similar way to alpha, but still limits you to 4 textures to enable height blending
tired sigil
My main problem is I'm working in Bundles, and they can't hold C#. So doing a big thing like MicroSplat won't really work if it has script dependencies.
😦
regal ginkgo
Have you tried just re-attaching the script after you import the asset bundle?
tired sigil
The client doesn't have the Monobehaviours for MicroSplat, so they won't carry over as a bundle.
Which is why I'm looking for a strictly Shader solution
regal ginkgo
Can't you add them to the client?
Haven't used MicroSplat specifically before so not sure what's required
I am setting my levels up as prefabs instead of bundles because of the MonoBehaviours, however I don't need to stream load asset bundles or anything

Hi!!! I have an application called terrasculptor 2.0 where it can generate very massive and natural forms of terrain. I was wondering what files Unity supports so I can see if this can export a compatible file. Apparently it can support Unreal engine's old 3rd generation too so it makes me wonder about unity.

I just want to apply a different color to my terrain
tame crypt
I don't have the Edit Textures button
formal zephyr
So, I have a sector of Terrain that I want to change the height on it, but I do NOT want it to physically change. Normally, when I change the height, it scales everything: I was to make the height Higher, but I don't want it to scale. How do I do this, either through code or the inspector?
warm radish
@formal zephyr you'd have to do it through code. we dont have anything like that built into the editor nor do i think we have that in the terrain tools package.
@true sail we use .raw for height (.png, .jpeg, and maybe .tga if you have the terrain tools package installed). for alphamaps we use "terrain layers" which are a custom asset for terrain that contains info like albedo texture, normal map, etc along with tiling and offset for sampling the textures in our shaders. we then map those terrain layers to splatmap channels when blending materials for the terrain
formal zephyr
@warm radish Okay thanks, I think I have a good idea how to do the scale, I'm planning on doing a 7-fold height increase, so I can use use the exact 7X multiplier to my advantage!
However, one issue: I also want the terrain to be just as detailed as before, but when I increase TerrainHeight to 4200, I can't smooth it nicely, it still has bumbs and courser terrain than it did before even when I smooth; How do I compensate so that I can still have features be nice and smooth? Do I mess with Heightmap Resolution? If so, how? (I tried changing that but didn't have any luck)
Top one is at 600, bottom two are at 4200
They are much rougher and coarse after the increase
warm radish
ya you might also have to alter the height resolution. your precision per texel decreases as you increase the height range. but that will make use of texture filtering when blitting the texture into the new destination texture so that will only get you so far in terms of maintaining your heightmap fidelity
you're still going to lose some data
formal zephyr
I'm okay with making new terrain;
I just want to be able to make terrain with the same quality;
How do I do that?
warm radish
ah ok. then ya, definitely try bumping up the heightmap resolution
you still might see rougher surfaces though since you are still dealing with a 16 bit floating point heightmap
but they shouldnt be as bad
formal zephyr
What do you mean about the 16 bit floating point?
warm radish
it's the format for the heightmap
each pixel in the heightmap is a 16-bit float
normalized float that is
values are always going to be 0-1 and the height range on the terrain settings is used to multiply the values in the heightmap texture to generate the actual height of the terrain
basically just trying to say that you still might see some features that arent as smooth as the terrain with a smaller TerrainHeight
formal zephyr
Okay, I think I understand!
Is there any way to change to a higher bit float for heightmaps? Or is that impossible?
Or, any other workarounds you would suggest?
warm radish
it's not possible atm unfortunately
formal zephyr
Okay, good to know; This has been very helpful, thank you!

@warm radish So since the terrain has multiple files it exports as, what is the main file name it exports as? I can export all of these, but not as a singular file.

@past sequoia you need to apply a shader that can move the vertexes.
you can do it yourself in shadergraph; https://www.youtube.com/watch?v=L_Bzcw9tqTc
or aplify
or use this fantastic shaders: https://boxophobic.com/
i use the THE VEGETATION ENGINE, it does simulate collision, subsurfacing, cutting, falling leaves and seasons.
it easy to use super price for what it does. Work on almost every RP and old Renderer of Unity.

@cunning raven do you know the difference(s) between The Vegetation Engine and Stylized Grass Shader? https://assetstore.unity.com/packages/vfx/shaders/stylized-grass-shader-143830
cunning raven
@solar onyx what i know is that the vegetation engine is a complete system layer based that has converter system that lets you any type of object as prefab convert to the system and back. it has seasoning color, wind, Cutt foilage, foilage collision. falling leaves etc all in one system.
the other system i do not know, sry. but i see that stylized grass shader seems only work on SRPs that is am major difference.
what i know is that Vegetation engine has a very decent support on his discord server and its all so easy to use.
sry i could not say more about the difference, maybe im also very biased by the Vegetation engine since i shipped products with it and i love it so much 😇
this is URP i only used it with urp and android
and of coarse pc

Good morning everyone, hope everyone is keeping safe. I just joined and am impressed by the quality of work and depth of knowledge here.
My first question ( I had a look on the forums, but was overwhelmed by conflicting answers ) is what is the unit size in Unity? Is it meters, ft, km, etc? Additionally, does the size affect cell size and is there a max (or recommended don't make it bigger than) size for terrains?
Apologies for the multipart question. Thanks for your time!

@wise hazel 1 is equal to meter. 1 1,1 cube is 1x1x1meter . if its about environmental design or even physics i would recommend you stay in realworld sizes meter
if you activate probuilder and turn on sziing you get metric display it can help

Ah thank you. It seems that TVE has much more features including a grass shader whereas the stylized grass shader only has a grass shader
kind flare
@cunning raven Hey. I also have the issue that i dont know how big what should be and how the sizes work in unity.
So what you said means, that if i create a normal cube its 1x1x1 meters ? So a 2meter tall player character at scale 1 in unity should be twice as tall as the cube ?
I had many tries starting to create my own terrain / world with trees, rocks, caves and more, but i always failed to handle sizes of stuff i model in blender
Which makes it a lot harder

@kind flare yes, if you download a mixamo humanoid character or download the unity mocap essentials you will have also real scale
there is an iussue with many DCC programs such as cinema or Maya, if you not specify the export right it might be to large or to small
kind flare
so they have Scales: X-1 Y- 1 Z-1 but they are they right size ?
cunning raven
yes 1 unity equals 1m
kind flare
But how do i know what size objects should be if they should have the same size in unity
For example if mine character is 2 blender cubes tall. Will it be the same in unity ?
cunning raven
use mesurement palette in your programs
i work with modo and i can display mesurements
in cinema is also only unity and maya to
but if you export OBJ or FBS you can mostly specifiy the unit
or you can specify in global setting of your DCC software
kind flare
Okay

I will create a stone for testing that should be the size of a unity cube to see how that works

which channels do your textures have on the terrain layers in use?

@spiral onyx A current limitation of Terrain is that it only supports height values between 0-600 locally. You might be running into the height cap
spiral onyx
yes I am running into the 600 height cap
at 4
the height of the terrain was set to 4 by the script
I can't change it without it doing this
which is not what I want because it messes up everything else
the stairs no longer fit correctly
nimble sable
If I'm understanding your problem right you could do this
- Have Terrain Tools package installed
- Select the Terrain Tile on the left
- Select Paint Terrain
- Select Set Height
- Set height variable to match the top of the stairs in the world and hit flatten
That should adjust the Tile on the left to realign with the stairs
nimble sable
In Terrain Settings try changing the Terrain Height there, I'd be curious to know if that lets you go higher
Set it to like 1000 and see if you can then set the terrain higher
spiral onyx
yeah as I said, changing that causes the entire terrain height to change
which isn't what I want since it causes everything to be no longer scaled correctly (stairs wont fit correctly etc)
nimble sable
I mean first change the Terrain Height to like 1000 or 1500, then after that reapply the set height so it aligns with the stairs.
The first step will set a new max value Terrain can go to, but it'll scale up your current Terrain as you're seeing. If you reapply the Set Height data after you change the ceiling I think you should be good to go, assuming I'm understanding correctly.
In this Gif I start off at the cap so I can't paint any higher, then by the end It's realigned with the cube but I can now paint higher
nimble sable
It should also go down to 0, I just didn't do that in this gif

Hey, is it possible to create a smaller terrain by default? When i create a Terrain object it is like 1000x the die of a cube and i really dont need such a big terrain. If needed i would rather add additional neighbor-terrains afterwards. I hope you unterstand what i mean and can help me
nimble sable
@kind flare There isn't a way to create them smaller by default (upon initialization), but if you use the Terrain Tools package from the package manager it has the capability to split existing Terrain objects into smaller Terrain objects. Hope that helps

Yes. i just dont know. My player is double the size of a unity cube and the terrain is gigantic

I have a question, if its not a good practice to use more than one mesh collider, how will I make my rigidbody + mesh to not fall through the terrain?
Should I use the hitboxes instead (not very precise..) ?

@nocturne hearth Don't cross-post the question. Pick a topic.
Did you set your mesh to be convex?
nocturne hearth
I did and it works but from what I understand its not a good practice to use mesh collider (performance wise), also I will be needing more than one..
MP game
drifting crown
It depends how complex it is. You can also use simplified mesh of the same object as a collider if you need some features on it.
nocturne hearth
Ok could u get me started on that? tutorial or what should I read about? how may I achieve that simplified mesh as a collider?
and tnx upfront dude
drifting crown
If you have a complex mesh and it can't be reasonably covered by basic collider shapes you can create a basic frame of it in a 3D editor resembling its shape and use in a mesh collider.

Hey quick Q - How viable is it to have a second Terrain directly intersecting the primary? The goal is to use the second Terrain as a kind of 'Mountain Cover', that lifts up/disappears when you walk under it. Trying to figure out if I should just create a model out of the mountain terrain instead, or if it's okay to just have an intersecting terrain.

@tired sigil should be fine to have overlapping terrains. Painting on them might be a little weird sure to intersections though

dire flower
Why is my grass taking on this red tint? The green one in the foreground is how it looks normally, while the red ones were painted on as detail meshes:
As you can see the dry and healthy colors are white, and the grass tint is also white, so I have no idea where this reddish hue is coming from.
solemn harness
OK I added layers but I cannot paint with them what am I doing wrong
do the mats need a mask to paint?

@dire flower is there a tint on the grass detail? there also might be a setting for detail tint / coloration on the terrains settings

no renderpipeline installed correct?
dire flower
What's a renderpipeline?
I'm gonna assume no, since I didn't install one and I'm pretty sure none of the stuff I installed would have included that.
dire flower
It seems like the issue I'm having with my grass and flowers turning red may be due to the meshes having vertex color:
As for why these meshes have vertex color, I think the vertex color is used by the shader provided with the asset bundle I purchased to control the effect of wind on the foliage? Though if that's the case, I'm not sure why I'm not seeing a gradient from bottom to top on them.
I just double checked and the wind seems to affect all the flowers equally, so my theory about the vertex colors being used for wind is probably incorrect.
dire flower
Okay so I did a little more research... So in regards to the vertex colors being used for wind, this asset does include a shader with a wind parameter which can be set to use vertex colors, UV, or vertex position to control wind strength. So presumably they included the vertex colors to work with that. But I have found that this shader does not appear to be applied to detail meshes applied to a terrain. Changing the settings for the material only affects individual clumps of grass I drop into the scene view. And the wind settings for grass in the terrain options do affect the grass I add that way.
Why the author of this asset chose to use vertex colors in that way and assume people would be placing thousands of grass clumps in their hierarchy rather than painting them onto the terrain as detail objects, I have no idea. At the very least, he should have provided assets with and without the vertex colors because now I have to load every mesh into blender to strip them out and hope it doesn't screw up any of the LOD stuff that I don't know the implementation of. Also his trees don't seem to suffer this same issue. Perhaps Speedtree uses a similar setup for trees, and Unity knows how to deal with that when trees are involved? Or maybe if I look at all the trees I'll find some with the same issue.
covert shale
@dire flower. You’re using the Nature Renderer asset. Have you tried hitting Play? Or reading the instructions? From what I recall that’s what your grass look alike when you’re not in play mode. Saves bandwidth.

warm radish
@buoyant tiger what is the texture format and what is it being imported as in the texture's import settings?
@delicate pivot you might want to break the mesh into smaller pieces. there is culling of triangles that are rendered to screen but that's still work that has to get done that you might be able to reduce the impact of by thoughtfully separating your geometry into smaller chunks. you should profile it if possible though and see which is better in your case
with smaller pieces, you will probably be able to make use of other graphics features to improve rendering performance, especially if you end up reusing some of the smaller pieces throughout the scene

If those trees were painted or hand placed then that is the most likely problem.
nimble sable
@solemn harness When you're painting on Terrain you're hitting the cap of detail meshes that can be placed on the Terrain. There's a known issue with the Target Strength setting where it defaults to being way too strong. Try removing all the detail meshes you currently have then turn Target Strength way down (something like .05) then try painting again. It looks like there might be another issue with it not using the proper Material though, I'm looking into that now.

@woeful drift no documentation that i know of. and i havent necessarily tested any upper bound regarding the size of the terrain. you can probably make them as large as you want. the main limitation we enforce is the size of the terrain textures like the heightmap and control map.
as for the number of terrain objects, that would be as many as your machine and the other machines you run your game or application on can handle

@warm radish if I would build a 10x10 terrain map then setactive(false) all but one, would resources be used?
I guess that’s really kind of a general question too about game objects using render resources when setactive(false)
My plan was to build the map out of 1024x1024 terrain objects than just have the neighboring terrain activate and deactivate as the player moves through the map.
I’m trying to keep it simple using what unity already has built in instead of code. The end result would be a Skyrim like map but split up by multiple terrain objects, maybe as many as 1000 total objects (highly unlikely but I’d like that ability).
Is it RAM, VRAM, or a combo that decides the amount? I’m using the i7 9700 with 6gb video and 32gb ram.

"TerrainToolbox: Imported heightmap resolution is not power of two. " what does this means?
keen latch
@pallid garnet ... Terrain heightmaps must be the same length & width
and these values need to be a power of 2 exponentially ...
2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096, etc., etc., etc.
You actually need to add 1 to these values ... that is 1024 polys actually required 1025 data points so a terrain 1024x 1024 the height map needs to be 1025px x 1025px

Can anyone help how to make mask map for a terrain
Its been a week and I can't find solution of it
glad pine
Hey @rose sentinel! Mask Maps are created by packing texture data within individual channels which are commonly done in software like Photoshop or Substance painter. What you'll want to do is take the textures you got from TextureHaven and pack them into the correct channel.
R — Metallic G — Ambient Occlusion B — Height A — Smoothness (Diffuse Alpha becomes Density)
Here is the page listing what textures go in the individual channels.
https://docs.unity3d.com/2018.4/Documentation/Manual/class-TerrainLayer.html

@glad pine smoothness means roughness map or spec map

smoothness is the opposite of roughness. they are each the complement of the other ie smoothness = 1 - roughness and roughness = 1 - smoothness

RenderTexture.Create failed: format unsupported for random writes - R16 SFloat (45)
it will not allow me to use terain at all. As soon as I try to mouse over the scene window with a brush, the display goes black and it throws this at me
Googling it just finds other people with the same problem but no solutions
and of course Unity's manural has absolutely nothing of use.
elfin barn
OK, to anyone else having this problem: it seems it's a bug in the Terrain Tools package - if you install that package you won't be able to use terrain brushes if yu're on Mac - looks like Unity devs didn't notice Mac's don't support that type of rendertexture mode....and hard coded it into terrain tools.
warm radish
@elfin barn thanks for the report. can you share the callstack for the exception, if there is one? and which version of Terrain Tools are you using? you can either post those here or pm me

I don’t have the call stack cos I fixed it and moved on. Most current version (3.0?), running on Mac OS X.13

But appearently it's not performant in HDRP and I actually need it for VR as well :/ I'm going to try the NatureRenderer since they have a free trial version.

@warm radish i just re-installed the tools; some of the texture brushes such as Erosion "work" but they don't function properly - they simply set the vertexes painted on to 0...
the Raise or Lower terrain brush however (the one I was talking ahout before) does the same thing it was doing last time I had the Terrain Tools installed; it errors out and blacks out the Scene view
I've takena . screenshot of it here
here's the portion of the stacktrace (I'm not gonna send you my whole Editor.Log, it's huge!)
it does NOT happen if Terrain tools are uninstalled - the raise/lower terrain tool works perfectly once the Terrain Tools package is removed
my guess is something in Terrrain Tools sets the renderTexture type to "R16 SFloat" overruling the system defaults etc
System Info:
Mac OS X 10.13.6, 3.1GHz Core i5, 12GB RAM, AMD Radeon HD 6970M 1024MB VRAM
(so yeah, older chipset but it doesn't have any issues running the terrain system without the terrain tools package!)
Unity System: 2019.3.13f1

and that's interesting...just noticed, the reason teh Erosion tool didn't work is it throws a different error...stacttrace for that is here: https://pastebin.com/qPqV5rPC

I am hoping this is the place to ask. I am working on a landscape build, and it seems like edit/undo or CTRL Z when using Terrain Raise or Lower will undo mass amounts of Terrain. Example: I can add 5 different hills and hit CTRL Z and it undo's them all in one shot. I can do texture and it works properly. Any ideas??

Hey @mild patio the video you were watching utilizes the Terrain Tools package. You can get it from Windows > Packagemanager
Then make sure you are showing all packages and in the advance tab toggle on "Show Preview Packages"
@simple patio Looking good! I always recommend trying the Erosion brushes in the Terrain Tools Package if you haven't. You can do some cool things like simulate hydro and wind erosion. Here's a blog showcasing some of the tools (https://blogs.unity3d.com/2019/08/15/accelerate-your-terrain-material-painting-with-the-2019-2-terrain-tools-update/)

@mild patio Terrain currently doesn't support flipping/sculpting downward. You might have to use a 3rd party tool to create the Stalactite or possibly look into Polybrush! (https://www.youtube.com/watch?v=QHslFO0vlGg).
@swift oyster That is very strange. I'll try and look into it, but I haven't been able to repro this issue.

I have 10x5 terrain grid with each grid at 4096 pixels. I'm new to working with terrain and about to get into thinking about how level of detail will work with it.
Does anyone have any suggestions for items i need to research or troubles I may run into?
grave basalt
@woeful drift do you mean the terrain or the stuff on the terrain.
The unity terrain hase some build in feature to deal with stuff like trees or other terrain elements to make them to Bilbords / cull them if they are to far away.
And the terrain des subdevide it self depending on how far away you are so that should not generate to much geometry.
If you are tinking Memory bceause all the 150 4K texture can be a bit of a memory hog.
You could put each terrain into a seperate scene and load them additily wehn you are actualy close engoth to see it.
woeful drift
@grave basalt i want the trees and other objects to be 3D models. I know it’s impossible to populate the entire map with objects.
The scene loading is a good idea. I haven’t tried that to test if the NavMesh would work without code.
Could I just use SetActive() on the terrain and objects when they are “in range” of the player or will the inactive terrain and objects still take up resources? I plan on splitting the terrains up into smaller “chunks” in code than have the objects instantiate base on “range” of the player than just hiding them with SetActive() when out of range.
Is that even possible?
grave basalt
@woeful drift objects that are disabled do not take CPU time but the memroy used by the objects is still loaded
Another good ting to use are LOD groups
doing chunks sounds good
woeful drift
@grave basalt so would instantiating the objects when in "range" of the player by chunks be the correct way or just keeping them inactive in memory? Obviosuly amount of objects being loaded would have to be considered but I'm sure ite probably better not to take up that memory right?
With splitting the Terrain into chunks I could use the LOD groups based on "range" of player than.
grave basalt
@woeful drift its allways a balance on loading stuff in the background and keeping the resouce usage under controll, how it needs to be balangsed depens on your specific assets and how you handle the loading
lod groups help on the rendering side
woeful drift
@grave basalt do you think I'm thinking correctly?
split into chunks and manage like how you said with code of loading and what not?
grave basalt
thats sounds like a good way to go

@warm radish nope - it might just be that I've installed and removed the terrain tools a few times from that project...(sorry for late reply. It's really hot weather here in Scotland so been spending it in our lovely real-world terrain instead (mainly the bit where the shore mesh reaches the sea mesh!)

@woeful drift Yes you can create high quality realistic landscapes using terrain. You'll most likely want to combine terrain with photogrammetry textures/assets for a realistic environment.

@elfin barn ha! no worries. glad to hear you are enjoying the weather.
i think i have enough info for this now. thanks for the help. i'll file a bug report

Is that possible? My query above 
glad pine
@mild patio Currently Terrain doesn't support sculpting arch's like stated above. For that you'd have to create an arch asset/mesh that you'd use in conjunction with terrain.

Is there a way to make certain textures not seamless? Like a tileset that repeats in older RPG games?

Hello Everyone, I am new to Unity and may just be missing something but I can't seem to use my 3d grass object with the terrain paint option.
Terrain only uses 2d assets for the grass paint but if I use the tree paint then my grass is really small.
Any ideas?

You can add the 3D grass as a detail assset

When I do that the healthy and dry color seem to take over the material I put on it.
Or maybe its because it has no shadows

Hello everyone, I am building a forest survival game and I have really bad performance issues when i am adding trees to the scene, I have searched over the internet but I didn t found any 100% sollution, if anyone has any idea how to help me pls dm me, I have a lot of questions about possible sollutions
I know this issue is very old and known but some of the sollutions were to make static trees and bake the light, but i need wind and also i have a day night cycle system

Hello everybody, does somebody know why my Navmesh would render on other height and not directly on my surface?
glad pine
@meager hornet Do you currently have the Terrain Tools package within your project?
Hey @nova narwhal the first solution that comes to mind is, have you tried enabling GPU Instancing on the Tree material. This way trees we'll be batched and rendered together minimizing draw calls.

@glad pine hi, thank you for responding, yup did that
My trees are from conifers pack and standard assets, the conifers have LOD

I'm working with the Unity Trees today.
Got a nice test texture with Albedo, Normal, and Spec
The [Nature/Tree Creator Bark] Material, likes to swap itself out.
The "Optimized" texture that it swaps in uses unconventional channels to try and do Normals and Gloss.
I can't wrap my head around how to convert my normal to just (GA) and then drop the spec in the R channel
I'd really just like it to stop swapping, Anytime I bake lighting or click on a diffferet node it "updates".

Progress! I'm working to bring together several disciplines to create a terrain/world that can be explored; in time there'll be a couple minigames as well.
Everything here is subject to change.

Ok so I have updated the question in a more professional manner, any help is welcomed https://forum.unity.com/threads/optimising-dense-forest-scene.905081/#post-5938820

hello i have struggle with colorint the terrain

@night parrot
I wish we could reorder the parameter drop downs, but you need to add/build a layer first. Be sure ALSO click the ADD button in the dialog that comes up. I've built the layers/grass/trees before and moved away from it without hitting it; means you get to redo it. 🙂

Does unity 2020 allow digging. Want to know if it's useless to upgrade or not

This goes on.

I need some help with the tilesets in 2d, would this be the correct place to ask?
