[glass wigeon]

hello guys, i did research on internet about HDRP not supporting details on terrain

but didnt found so much

im using the default HDRP by unity

it doesnt draw the grass when i do place them

[daring yacht]

I have added 2000 trees through the mass place trees button, but it won't let me remove some trees with ctrl click

is there something I need to do?

I have the tree selected in the paint trees option

[snow cypress]

I'm two days into learning Unity, and I've run into a problem I have no idea how to solve. I've downloaded and imported the terrain toolbox addon, but I'm not seeing it in the drop-down menu under Window. before posting this, I wanted to see if anyone else has had this problem, and the only thing I could find was an unanswered post from 2019 in the #💻┃unity-talk channel. I know the addon is installed correctly, because I can see the brushes, textures, and other bits in the asset folder. The button for the Terrain Toolbox is nowhere to be found. If any of you more experienced people can help, I would hugely grateful.

[visual cliff]

Does anyone know how to make grass and leaves and branched "run on a toaster"? Because I would expect grass, and leaves and such are very hard to render do to the quantity? How can I make them render better?

[dull comet]

why does my terrain look shiny in some areas?

[visual cliff]

I would advise looking at your texture settings and changing its settings (metallic and smoothness) Though I still have this same issue with both turned all the way down.

[dull comet]

Yeah both at 0

this just started happening when i changed the texure compresssion in my build settings

@visual cliff put your aplha source to none

[visual cliff]

Where? Did you figure it out?

[dull comet]

ok go to your texture( I turn the resoultion down to 512 also)

and set it to alpha source > none
Disable your read write(thats twice as much memory usage no need for that)
put it to power of 2 > ToNearest

[visual cliff]

Woo! Thank you so much!

[dull comet]

im doing a build for android so i use override for android and compressed ASTC

only thing i have been going thorugh all the textures and changing them and it wants to reimport all my assets each time i do it

and then i have to sit and wait for 3 hours for each, so if u edit allot at once be sure to have your netflix ready

[visual cliff]

Alright cool! Thank you so much I have been trying to figure this out for a couple days now.

[dull comet]

it just happened to me lat night, or this mornining, i was changing textures to get them to render faster on android

[shell jolt]

Turn on instancing if you have hundreds of them, do note it won't work to legacy devices

[frozen depot]

Hello there! I'm looking for a smart way to copy-paste 2d custom-physics for a tilemap. As you can see i got 3 sets which share the same outlines but have a different style. This is the case for several assets of mine and i did this once for my overworld and I dont think i can handle this anymore. The solution to singly copy them all is driving me nuts. Any suggestions on this?

[limber kraken]

I would have one tilemap for collision and another for the actual art. unity allows for tiles with no rendering

[frozen depot]

I dont think you got my point, I might have explained it bad

I create custom physics for every tile up there. So i can walk into the slightest area.

Like the stairs. You can walk right up the stairs until there's the border/grass. And I have to do that 3 times even though they are pretty much the same.

does this make sense?

I also got a tilemap for collision, but its not detailed enaugh to fit every tile. And i really don't want to create a map and overlay the colliders everywhere since my world is pretty huge.

[cold hinge]

@tawny ore maybe someone here could help. Here’s a forums post that might also help https://answers.unity.com/questions/1125545/cant-paint-terrain-or-use-terrain-tools.html

[tawny ore]

Alright cool thanks.

[drifting badger]

I had to up the import scale for some tree meshes from 1 to 3 and now the generated billboards are way too big.. Is there any solution for this?

Nevermind, found out that it was the random tree height just not being applied to the prefabs...

[visual cliff]

Does anyone have any tips on making realistic trees? I want to make the most realistic but easy to render and.. exist "on a toaster".

[shell jolt]

Make two versions of your model, a high poly and low poly, then bake the normal map from high poly into your low poly one... Whether it's running on a toaster or not, this a bit of trials n errors on your part, meaning, test them out yourself

you can do this technique for lod as well

[visual cliff]

Hmm but How would I add leaves to something like this?

I was thinking of how to make trees with the tree creator tool. Is that a good idea?

[gray ice]

Does anyone know how to apply rotation to terrain-painted details based on the steepness of the terrain? Right now I have patches of grass hanging mid-air when painted on steep terrain.

[shell jolt]

You must make your own custom tools unfortunately , I made similar scattering brush but sadly it won't work for the terrain, only for regular meshes.

The idea is to get the normal direction split it's dimension so you'd get the center most of it then add your own calculations for the offset position so it can be centered on the face of the meshes' coordinate or according to the grass-detail asset's dimension... this looks complex n yeah, it is actually kinda finicky to deal with if you had different meshes with weird world's origin (non-centered origin)

[shell jolt]

I'm not sure what tree creator is, I assume that's the built-in one in Unity, if so, I can't answer that... I suggest use 3d software instead such as blender. Many procedural addons to make trees/foliage in blender, and you can use decimate modifier to reduce the amount of poly on the trunk part

[mystic geyser]

Can anyone recommend some terrain tool assets that replace the Unity terrain?

The terrain tools even with the package are so completely broken that I can't fathom how stuff like this even gets shipped

Working with brush strengths of 0.005 to avoid maxing out your terrain height with one click etc

Smoothing not working at all

[shell jolt]

wdym.. I used smooth brush a lot, and it did a great job

[shell jolt]

elaborate pls

[mystic geyser]

Having to use brush strength of 0.00X digits to avoid blowing up your terrain

Meanwhile the smooth tool is effectively useless regardless of strength

[shell jolt]

the strength ratio is sadly based on your heighmap resolution..

[shell jolt]

I recommend use Noise brush instead to elevate the terrain..

And as for smooth-brush, use the most soft brush... it works best with those soft brushes than a sharp ones

[shell jolt]

the higher the heighmap resolution, you'd get a smoother transition for any brush operations.. the default 1025px is not cut for the job, bump it up much higher.. and ofcourse it comes with price, performance wise, especially in the editor

@mystic geyser and here I posted sometime ago how smooth-brush in action #⛰️┃terrain-3d message

[mystic geyser]

It's not that it doesnt make a smoother transition

It just literally doesn't smooth at all lol

Extreeemely minute

[shell jolt]

You're doing it wrong! see the post I linked above... it would work, with a certain type of brush.. namely, the brush with smooth edges

[mystic geyser]

https://gyazo.com/08417da1056e83f34125db7f0ce1e6d6

Meanwhile with same brush strength for raise/lower

https://gyazo.com/06d52f534fd35cacf38727e57d839cb4

Except you can never smooth it back down

I'd expect it to work like sculpting in zbrush or blender

But it just doesn't

Same with any kind of detail painting -- you either get 0 objects with 0 target strength or you get 1500 meshes with 0.0625 target strength

[shell jolt]

Just tested it, it worked like I mentioned above

change your brush type

[mystic geyser]

Just tested it with a changed brush type, it didn't work like I mentioned above ;/

[shell jolt]

🤷

[mystic geyser]

https://gyazo.com/c353f8bea42099c73dd9214d224bddd2

See how extremely slowly it smooths

[shell jolt]

the above video was made with just this setup

not even at max strength

[mystic geyser]

My terrain resolution is 4k

[shell jolt]

I'm using terrain tool 4.x. btw, perhaps that's matter, but who knows

[mystic geyser]

I'm using unity terrain tools 4.0.3

[shell jolt]

they did bunch of changes in the 2021.2

yep thats mine too

[mystic geyser]

I have 2021.2.3

2021.2.3f1

Just add it to the rest of the stuff that is broken in Unity

If you add more than 4 layers to your terrain in URP it bricks your project

Despite the documentation saying it should support endless layers in URP at the cost of performance

etc etc.

[shell jolt]

4k terrain is a big deal.. especially if it's massive in size.. so.. uuhh

[mystic geyser]

It's small in size

4k is just the resolution and should not matter much honestly

[next tangle]

anyone has a good yt video to make realistic water I don't know which chat I should write it in. I have been messing around for about 3 days now looking everywhere and I cant find a good explanation on how to make my own water material and all. I have also created it in blender but could not export it to unity

[warm radish]

heya. are you getting any errors in your console window when you trying to smooth the terrain?

[mystic geyser]

@warm radish None

[warm radish]

can you send a screenshot of the smooth controls section?

[mystic geyser]

@warm radish That solved it -- blur radius is set to 1 by default

https://gyazo.com/852774817d187fd1c5c28e6707bc63e8

having it set to 1 renders it more or less inoperable

[warm radish]

sweet. maybe something for us to think about there UX-wise. blur radius is currently based on the heightmap resolution. so with a 4k texture, that's gonna be pretty small depending on your terrain size. maybe it should be a percentage based on brush radius instead

[mystic geyser]

@warm radish You probably can't tell, but do you have any updates when it comes to the memory leak and crash upon exiting play mode caused by having more than 4 layers on terrain in URP? vertx submitted a case using my project with a guaranteed repro

These people don't seem to have isolated the cause but it's most likely the same reason

https://forum.unity.com/threads/tls-allocator-alloc_temp_tls-problem-when-selecting-my-terrain.1197934/

[warm radish]

looks like it is still in "triage" meaning it's yet to be looked at and assigned to a team. i'll assign to the terrain team

[mystic geyser]

It was notoriously hard to track down, I was struggling for 3 days

Thanks

[worldly dune]

Hi! What terrain tools are people using? After manually adding com.unity.terrain-tools@3.0 I managed to install it in 2021.1.23. Is this discouraged?

terrain-tools 3.0 look really nice, and https://www.youtube.com/watch?v=smnLYvF40s4 is a good tutorial

[verbal lichen]

Is it possible to use Unity Terrains for Mobile?

i need to use EasyRoadsV3 and the Assets seems to require Terrains to properly work

id wanna 3D Model the Terrain myself so they're alot less expensive to render but that doesnt seem to be an option

im considering using the Unity Terrain for the Roads and then 3D Modelled lower poly Mountains and such for anything other than the roads?

[worldly dune]

Does anyone know of a good solution to work around terrain textures being stretched on steep vertical cliff sides? I understand why it's happening and that a triplanar shader could help, but was interested in hearing whether this is something the terrain tools can help mitigate

[verbal lichen]

noticed that too

i think theres an asset for that

[ocean gazelle]

Hi all! I am planning on building out the terrain of my game using 3d tiles. I stumbled upon the Terrain Toolset and it seems like it would give me the tools necessary to create my tiles. I am thinking of using about 5x5x1 meters as the scale of my tiles.

Is creating my tiles out of terrain objects a reasonable approach? Is it doomed to fail for reasons that I won't see until much later in the process? Is there another tool that would make what I want to do much more simple? (when all you have is a hammer...)

Assuming this is a good approach, I then need to be able to design my tiles so that they snap/transition together seamlessly. I was using the Paint Terrain tools to get a decent rough version of a few tiles, but couldn't figure out a good way to generate tiles that will seamlessly transition from one to the next. My next thought was to do a rough version, export a heightmap, and then do the mirror/tiling in an image editor, and then re-import the edited heightmap. The problem that I ran into there was I can't seem to get the exported heightmap to have enough contrast to be workable.

Thanks!!
I am just starting out and am having some difficulties, and help would be appreciated. 🙂

[hybrid copper]

Hey and so how could I optimize the terrain so much until it basically looks like a ps2 game? Or is there a better way to render the terrain that im not aware of?

[shell jolt]

@verbal lichen @worldly dune you can fix it with Smooth-height.. see Smooth-height in action #⛰️┃terrain-3d message...

This is a common question every now and then, I wonder why there's no pin about this?

[shell jolt]

Optionally, set the verticality of Smooth-height to positive value, to something like 1 so those textures would be fixed upwards without changing how your slope looks like... 1 is high enough for 1025p terrain.. you may need a larger value if the terrain is 2k/4k + 1.. just play with it

These are undocumented for no reason by Unity... kinda confusing tbh

[worldly dune]

Thank you, this is a really great tip! I had all but given up and considered modeling all my canyon/mesa like mountains in blender. But that would have been painful from a texturing perspective.

Cliff sides will never be as good as horizontal planes, but this is definitely an acceptable compromise

[shell jolt]

A little tip tho, you can make a slope tile in blender, make sure they're seamless when attached from each sides... that said, use the terrain editor as base terrain.. but it's up to you

[worldly dune]

Thanks, will definitely use a combination

This is such a night and day difference

[shell jolt]

Glad you solved it 👍

[tawdry onyx]

when baking a scene is the step setting how close it bakes to the terrain or if it not then how would i bake a scene and have it bake closer to the terrain cause when I place my navmesh agents on it they seem to be floating a little up from the terrain surface.

[sturdy escarp]

Hello! I'm learning about the Terrain Editor. I'm reading a tutorial in Unity Learn and the screenshot that is shared in the tutorial page there looks like this

The thing is that in my Unity Editor window it doesn't look that detailed, it's all grey in the Scene tab

https://gyazo.com/1ad3e3d28ea44d6ce8224fafdb0e0809

I'm not sure how to fix that so it looks more clear how the terrain is changing

I found this, I tried different options here and it helped

[shell jolt]

you must assign texture to the terrain layer

[shell jolt]

I suggest to ditch this method and use triplanar shader instead, so just use your terrain as a base then all slopes, hills, overhangs are just gonna be moveable objects..

See triplanar shader in action... it can stitch objects seamlessly without too much efforts

[worldly dune]

Thanks, that does indeed look like a better solution. I've been researching triplanar (eg https://www.youtube.com/watch?v=eZqd68YaY2U) but struggled to find a good tool for it (haven't tried purchasing anything yet though).

[mellow sapphire]

Is it possible to change the sprite shape controller settings when screen size changes in order to make my sprite shapes fill the screen when i change device? Im refering to a 2D game ofc.

Ps I dont want to change the scale as it messes up my polygon colliders.

Thanks in advance

[shell jolt]

yes, you can follow that tutorial 👍

[keen latch]

@worldly dune ... Not a fix for the texture stretching on steep terrains .. but Look at TerrainToolkit. It's FREE & and great for basic terrain texturing plus it has ALLOT of terrain modifying functions built in (smoothing, eroding, adding noise, etc.).

[split verge]

im trying to apply a basic grass texture to a terrain, i simply cant, im trying to use a brush but it does nothing

[worldly dune]

perhaps another solution could be to go with a voxel terrain like https://assetstore.unity.com/packages/tools/terrain/voxeland-9180

[edgy portal]

Hey there,
Can anyone help me with how I can create a huge open world map? What are good tools for the design and how do I render everything properly etcetera?

[unborn summit]

Anyone know why when I call terrainData.size = new Vector3(256, 40, 256); the actual size of the terrain ends up being 2048, 40, 2048?

[shell jolt]

Looking at Unity's roadmap for world building, there's nothing much to expect tbh.. kinda .. sighs...

https://portal.productboard.com/dzcznunfgebtky7ipmhrc22z

[marble sentinel]

@edgy portal depends how much you wanna spend. Gaia is one of the best: few clicks everything is done costs almost 300€ if you want something for free but that only generates a height map which you have to paint and add grass and stones yourself then terre sculptor might work. Not entirely sure if that was the name. Another one would be world machine, not sure if it costs or not

[unborn summit]

Anyone know what could be causing this:

[last sundial]

im trying to make a pond with unity terrain, how do I dig down?

[shell jolt]

you must make the terrain higher when 1st time creating it

[past dragon]

awesome

[worldly dune]

I am coming to terms with requiring a voxel terrain system for my game. Does anyone have any recommendations?

[shell jolt]

Go for Blender and make your terrain with it.. no assets on the assets store can do what blender does

[minor vessel]

how can i make that the mesh is not selectable in single parts but in a complete Mesh for the Meshfilter component prefab ?

[barren oak]

gotta combine them into a single mesh in Blender or any 3d modeling software

[north crypt]

https://assetstore.unity.com/packages/tools/level-design/ferr2d-terrain-tool-11653

does this work on the latest unity version?

says 2017 and later i just want to make sure

[jagged lily]

is there an automated way to set the base height of a terrain to a certain number? i find it very annoying that you can't dig holes with the standard height

i can set the height of the terrain of course via "Set Height" + "Flatten Tile"; but tiles i add later will have a very strange shape

[bleak iris]

what kind of landscape could go well with this? cities are so complicated. (also don't mind the fps, obs sometimes does that to me, idk y)

so yh, if possible, not a city

[frosty shoal]

any reasons my scene view would be doing this clipping? 2019.4

How do I add grass?

[shell jolt]

Pray to Jesus to give you the most perfect grass mesh?.. JK.. 😃

Assign your grass object on Paint Details tab, just like you'd with the trees

[shell jolt]

Anybody experiencing this issue where all the tree thumbnails are not previewing?

Unity 2021.2... I'd love to hear a solution to this if any.. thanks!

[dusty storm]

@shell jolt I think it has something to do with the shader on those objects or maybe it's as stupid as the prefab not being at 0,0,0.. no it cant be that. Let me know if you find out.

[tardy orchid]

maybe enable the uv generation in the models import settings

[silver sierra]

Hi! Does anyone have a good method for making custom terrain in a quicker fashion than the way I'm doing it? I'll get into how I'm doing it in a moment:

I'm making 3d terrain but currently making it entirely in blender, and I'm just expanding it from a plane, I'm going for toy-like visuals (sort of playmobil-ish), so it doesn't have to be super defined, but I also don't want it to be super blocky,
So for that reason I don't really want to use other terrain tools to build up my terrain, so that it can be really custom and fit the material I'm inspired by better

^ That's Hype the time quest, which is the game that's inspired my current one, as a sort of spiritual successor, but with non playmobil assets [so that I don't get sued lol]

How do I make terrain in blender in a quick and effective manner?

[silver sierra]

This has already taken me roughly 3 hours to make. And it's a VERY small portion

[shell jolt]

In Blender, you can sculpt terrain very quick.. like super quick... with custom brushes.. 🙂 ...google those custom brushes for terrains/rocks

as for the blocky looks... you can use decimate modifier after you're done with the high poly

[silver sierra]

Thanks!!

[shell jolt]

you can get the blocky result with the default terrain editor in Unity I think, by lowering it's heightmap resolution (correct me if I'm wrong, never personally tried this)

[silver sierra]

Oh! In Unity? Not in Blender?

Oh oh, the terrain editor, I see

[quartz crown]

what are the tricks to making a decent terrain track? It took me so long only to make this abomination

[rose sentinel]

ok i have no idea where to ask this but

how do i make sprite masks work like in baldis basics?

where it puts the doors on normal walls or whatever

[rose sentinel]

Just testing out terrain and the paintbrush has a really annoying quirk which I don't know how to disable where it'll stretch to try and fit the shape of the terrain that the mouse cursor is over causing the size to change and this just causes more problems than any actual benefits on my end.

Is there any way to make it retain its original size whilst painting?
https://i.imgur.com/tOIouso.png

[thorny swift]

It does not changes the size, it is projected from top down perspective, so from your camera perspective it seems stretched, but from top down perspective it is still same sized brush.

[thorny swift]

Hi, try looking into https://www.world-machine.com, you could setup a curve and generate map based on that.

[quartz crown]

hmm i see, thanks

does it do canyons?

[thorny swift]

Or if you wanna free solution to make some sort of terrain fast based on track, you could setup a spline in tools like Gimp, blender, and overlay it with some noise texture. Then simply import it as heightmap.

[quartz crown]

yeah free would be preferable 😄

[thorny swift]

yes, it makes pretty much any shape you want as it is nodes driven system.

[thorny swift]

so yeah, making heightmap out of tool like gimp or other free painting programs might be a lot faster than sculpting it in Unity 😄

[quartz crown]

well i dont exactly want a heightmap but a proper looking map

im kind of amazed the terrain tools havent changed much in 10 years

if anything its more cluttered and slower to use now

[shell jolt]

Use terrain editor for base only, like grounds, then use Blender or any 3d software of your pick to make a tileable slopes , overhangs, hills, caves etc combined with triplanar shader

Terrain editor is pretty much bare-bones in terms of modelling in Unity, but it's a nice tool for quick prototyping and for simple terrains

if you install the extra terrain tools you could make terrain holes

[solar siren]

So I encountered a issue that when I try to paint trees the trees are a bit down or clipped in the terrain

Im facing the problem with this specific tree pack rest are working fine

[frosty dove]

Could be that the prefabs miss colliders and the terrain cant calculate them for you?

[shell jolt]

@solar siren check for its world origin...

[mellow sapphire]

Hey , why even tho in my spriteshape profile angle ranges the sprites look fine, inside the game are inverted?

[shell jolt]

my current workflow with Unity's terrain system... wish Unity would improve the tools to make; cliff walls, bridges, overhangs, true terrain holes (not just some hacky-janky terrain hole like we have now) .. Basically the terrain is used as a base ground

last but not least, shadergraph supports for the terrain...

[frosty dove]

Gaia Pro is what you are looking for

Still waiting when unity intergrates Gaia pro

Or use photoshop and blender to make a custom terrain

[heady field]

hi

i build an map with an unity asset. Is it possible to "draw" trees on this?

[shell jolt]

pls elaborate @heady field ... did you make your map with the default Unity terrain editor? if so, yes you can plant your trees!

Plant digital trees, save the world! ... oh.. wait

[heady field]

oh no

i used some mountains and moved them together

[shell jolt]

then you can scatter your tree with Probuilder instead

[heady field]

ok

[radiant plinth]

Yes

[verbal lichen]

what type of texture is it

like a nature texture?

try selecting URP>Nature>Speedtree8

[radiant plinth]

no the prototype gridbox

[verbal lichen]

in its shader

[verbal lichen]

oh then just do URP>Lit

[radiant plinth]

ok i try wait

thx it worked @verbal lichen 😄

[river mauve]

What if i want to have a enormous world (map) and i use the unity Terrain System?
When i create multiple terrains with the create neighbor terrains feature i get an insane batches count and my fps drop from 200 -> 60...
Can i just use one terrain object scale it up and increase the tris count of that terrain object?
Because if i understand it right that would lower my draw calls, right?

So how do i increase the mesh resolution? If increase the detail resolution it doesnt seam to do anything when viewing it with wireframe mode.

[frosty dove]

Quick question. Do terrain Holes still have colliders or is it pass trough?

[shell jolt]

You can enable Draw Instanced, pls do your own research on this..

For details, you can bump up the Heightmap Resolution, also do your own research on this

some brushes just won't work with it for unknown reason

[trail jetty]

Trying to create some terrain was wondering if i can get some help the youtube vods out there have different options then me so kinda confused

[shell jolt]

before the video usually they mentioned the version they are using

even so, there's not much changes done to the terrain editor

terrain editor in Unity is like a brother from another mother... not too much love poured into it

[silent dagger]

anyone who knows if unity is working on supporting custom terrain meshes ? my startpoint is usually real world terrain meshes (from autocad/civil/ etc) ?

[shell jolt]

Not really, no, but you can always put your custom meshes on top of it, like in this video #⛰️┃terrain-3d message

[silent dagger]

yeah, but i would like to have the terrain tools (painting grass, tree, etc) available for custom meshes 😄
Currently using third party plugins for that

[shell jolt]

yeah, that's where the terrain editor is lacking

making your own scattering tool isn't that hard tho.. otherwise just use probuilder to scatter your prefabs and don't be confused if some of your meshes are floating when using it 😃

[swift oyster]

Hey guys, I'm getting an odd bug all of a sudden. When I do "Set Height" in the Terrain it causes all my grass/trees to disappear. This only happens when I try to set the height by holding Shift and left click. Just clicking what it was previously set to works. Thoughts?

[thorny swift]

Unity hides terrain details so you can see what and where you are painting, not sure if it can be disabled, haven't yet tried.

[swift oyster]

Odd I wonder where that could be at. I've been working with the set height tools for months and haven't ran into that issue, but once I Shift + left click to set the height its all gone and wont come back then.

[frosty dove]

Yes this is why i really hope unity buys up Gaia

Gaia pro 2021

[swift kernel]

idk why but the terrain toolbox doesn't show for some reason even though i selected show premium packages and the other option while downloading them

[shy scaffold]

Tried refreshing ?

[south marten]

not sure if this is the correct channel to post this or not (tell me if should put this somewhere else). so i have an orthographic camera pointing at a cube, but the edges of the cube seem really pixelated, is there any fix for this? i couldn't find anything online and google didn't seem to understand what i was asking.

[shell jolt]

turn on antialiasing

[haughty birch]

Hi, does anyone know how to fix that trees on terrain are rotated according to the normal of where its placed?

[haughty birch]

this is what pretty much happens

I want the tree to rotate with the normal

[next shadow]

Anyone know if its possible to make tiled terrains from one large heightmap? i.e. have a 51200x10240 pixel heightmap that populates a a 50x10 tileset of 1024 tiles?

I know I can split the heightmap into a bunch of smaller files and import them all but if I'm missing an automated option it would save me a bunch of time to know about that.

[deep gazelle]

is there some way to make terrain go below 0 height

say if you wanna do giant holes or crevices below the general play area

or do people just typically start the terrain at a Y value higher than 0 to account for future holes they might wanna make

if that makes sense

[swift kernel]

i accidentaly deleted the terrain platform i had just painted so i went to window for the toolbox that wasn't there all though i downloaded the premium package from assests

i didn't even save project it just dissapered so i require the location of the terrain toolbox window if it's not from the window at the upper corner

[shy scaffold]

I had same problem just go to package manager and select preview package of terrain toolbox

[swift kernel]

cant sign on my unity id which sucks

[shy scaffold]

Yeah it does that alot i can't sign in either

[next shadow]

Just lower the group your terrain is in. My project is all islands so my terrain's 0 is at my world's -50 to make room for water.

I'm letting that terrain clip into a second terrain group that is just going to have height defined by stretched out noise to form a sandy floor.

So I should be able to get like 300 meter depth below world 0.

[deep gazelle]

im confused what you mean by group

[next shadow]

When you use the Terrain Tools preview package by Unity it groups your terrains and makes them auto snap together.

Its useful if you want to paint your heights manually over a large area.

[deep gazelle]

ah

I think I understand

[next shadow]

So those 9 in the middle are part of the same group.

[deep gazelle]

so youre using one terrain object for the main ground

and another for the ocean floor

or lake floor or whatever

[next shadow]

That's my plan, yeah. And ill just match the materials at the bottom and have the highest point on my seafloor terrain just clip into the lowest point of the island terrain

[deep gazelle]

ah that makes sense

wait now im having another problem

my initial solution was to have the terrain raised higher in the world position

so that I can make "holes" or river beds or whatever else

but now for some reason I cant lower the terrain

the lower terrain brush does nothing and paint holes seems to make square holes with no proper edges

https://puu.sh/Ixvbi/76b6c471ef.png

[next shadow]

I think the holes it makes assume you will be matching the edges in a mesh and using that instead of terrain in that spot

If that's a new terrain its probably all already at the lowest position possible.

Do you have photoshop or gimp or something? You can import a heightmap to get a good starting point.

[deep gazelle]

i set the height higher than it is at default because i was having this problem with the default height

its alright I think im jus gonna paint areas in one at a time instead of using set height over the entire terrain object and then maybe itll work

i have gimp I may do something like that in the future

thanks for your help

[next shadow]

No worries. I'm new to this too, just getting everything to work the way I wanted recently 🙂

[deep gazelle]

same the hardest part is learning enough to have a work flow

[next shadow]

Anyone have any idea why my 16-bit raw heightmaps import all weird? The terrain's all vertical walls with gaps in between.
I took a valid 8-bit heightmap that imported great but left all sorts of ridges on slopes that were supposed to be smooth. So I switched it to 16-bit, threw another gaussian blur on it, saved it back out and now it won't work...

[rose sentinel]

Is there any way to sync wind with multiple connected terrains? right now connections of wind terrains are not smooth

[shell jolt]

So your character can see the difference across terrains? 🙃

[analog basin]

Is there something so I can make the hitbox of my building fast? Doing it with the boxcollider takes ages

[shell jolt]

wdym?

[analog basin]

I used a asset for buildings, but I can walk thru them. So I need to use collider to make it so I can't walk thru it.

But using colliders is a pain in the b*tt

[shell jolt]

you can AddComponent from script... either way, nothing wrong with adding the collider by hand, most of us do that

[analog basin]

But it takes so long 🤣😂

[shell jolt]

yeah... game making perhaps not for you

[analog basin]

Need to do it for school 😂🤣 don't want to do it for work

So this is 1 time only

It's fun and all, but the colliders takes ages. The other things are kinda fun to do so

[woven kestrel]

anyone knows why my terrain texture looks repeated? i tried to increase the tilling settings but its always repeated, does this mean my terrain is too big or something

[shell jolt]

Dont see it from far away, look from you characters POV

the further you're looking, the more obvious the repetition can be seen

[fleet bane]

Mesh collider?

[analog basin]

Box colliders

[fleet bane]

I know, but colliders are the same thing. The only difference is the shape pretty much.

[analog basin]

Aaah oke, making a 3d game so I'm using box colliders. Will try mesh. Now going to play games with my friends 😂🤣

Every day a hour in unity is good enough for my school project. My classmates are doing it in the last week, so I'm doing pretty good I think.

The most time is in the terain, programming is ez.

Have a nice day

[fleet bane]

Mesh colliders are 3D only, and the terrain system is super easy

[analog basin]

Oke, i use 3d box collider or what it's named

[analog basin]

True that the terrain is ez, but it takes some time 😆

[fleet bane]

Mesh collider, then set it to convex (this depends on how detailed you want the collider to be)

[analog basin]

Just so u can't walk in to the building 🤣😂😅

Most terrain is trees and a path of sand

Trees have a natural collider so I don't worry about that...

Need to make a waterfall also, that will be some what diffucult I think. But I have YouTube and Google so no stress

[fleet bane]

Don't take this to heart, but a Unity's beginner should not be playing around with shaders. Start with core concepts.

[analog basin]

Just a basic waterfall, no shaders or something I think... Just some water going downwards

Downloaded an asset for that 😂

Most of the things are assets, trees are. Fallen trees are, buildings are, textures are. Water things are

Don't make it yourself harder make it easier 😂🤣 now I just click and poof there it is

[real knot]

Hello! I have a strange bug in unity terrain. I made a tree model and assigned it to the unity terrain, after that I changed the textures of the leaves to be more white. Now I saw that the leaves' textures are not correct(unity terrain uses the old one - image 1). If I make a copy of the tree and assign it to the terrain, all the textures are changed to the correct one, but when I press play/refresh the terrain they get reverted to the old texture(image 2).

[cold sedge]

I have no clue how this works.. but does the tree has a LOD system? (Level Of Details) @real knot

[real knot]

no

[cold sedge]

Have you changed the Terrain settings? (Any setting in there)

[real knot]

just fade lenght and tree distance

[cold sedge]

Then i have no idea.. Sorry, good luck tho!

[ionic agate]

Any way to get trees to work with terrain builder if they have 2 mesh renderers? (One for branches and one for leaves) I tried adding an LOD group and setting it to not cull the renderers but terrain builder still complains about having multiple mesh renderers and it doesn't display the trees

[woven kestrel]

why i cant place trees on the terrain? with paint trees

[ionic agate]

I'm also having this issue ^ My trees have 2 mesh renderers and set my LOD to cull nothing but still won't paint them

[shell jolt]

see your terrain editor tab, usually there's a warning why it can't be placed on a terrain

also check your console logs

sometimes the when the terrain is too convoluted with objects/meshes that you already painted before, you should set the Density value a bit higher

[woven kestrel]

i have these warnings but idk what they mean

[ionic agate]

I had the same warning, so I added an LOD group to the prefab (it was an fbx so I created a prefab with it) and dragged the renderers into the LOD 0 group and removed the other LOD groups. Even after adding an LOD group it complained that I didn't add an LOD group

[woven kestrel]

this worked for me. i can paint terrain with my tree now
https://youtu.be/dp8iTFYpaSM?t=1014

just a weird thing thats happening is that the trees dont spawn where my brush is

[ionic agate]

hmm, I did that and I'm still having issues. Oh well, I'm sure I'll find what my issue is haha

[fading pasture]

Guessing I clicked something but have no idea what. My terrain is no longer growing when I'm editing it. I'm in Raise or Lower terrain, not set height but I can't get my terrain any higher. full opacity and it goes to maybe 1 height and that's it

[shell jolt]

for prefabs that aren't being spawned on center of the brush, that's bcos the world origin is not at center...

[safe sable]

In PolyBrush How do increase the ammount of vertexs in my plane

[safe sable]

i did it but when i try to edit the terrain it turns black

[woven kestrel]

anyone knows why my trees are lying down when painting onto the terrain but the prefab is fine?

[safe sable]

it appened to me once i think people said to check the export settings in blender

when i try to edit the terrain with polybrush this appens

[woven kestrel]

don't you know which setings, i tried to change transform but it didn't fix

[shell jolt]

This is your problem 👆

Youre basically asking same problem over n over

And the solution is just as mentioned... World origin

Google it, n save your time... You'll find your answer regarding world origin in like 5 sconds

[whole wyvern]

hello there, i'm having this such problem

on 1000x1000 the brush painting does like that

if i decrease the terrain size like 1000x170 it does like that

[whole wyvern]

can i keep this on shrinked terrain?

[modern cypress]

you could decrease the size and then repaint the star...?

[whole wyvern]

is exactly what's happening, the brush shrink together

[whole wyvern]

when i paint in the terrain with not exactly proportions, spawns like this

[pallid kraken]

hi guys I am trying to make a mountaintop forest scene in urp. I can't find any free tree assets that works with urp. Can anyone suggest some assets? thank you

[shell jolt]

Any models should work you just need to remap all the textures into urp

[halcyon patrol]

Details are a texture ontop in terms of the data that is read.

So if you made a star in proportion 1:1 on a terrain that is 1000x1000 and then as you did changed the proportion to a non 1:1 ratio you'll get that. This is the same as resizing an image and doing the same thing.

Ideally unity terrains should stay square, if you want a rectangular shape, create smaller terrains with neighbors in a non 1:1 ratio, like 1:2.

Apologies for the awful reference image 😅

[whole wyvern]

cool response, tks

[rose sentinel]

I have a problem with trees. I click Edit Trees -> Add Tree and nothing happens

I know there should appear a section where I assign a prefab but it just doesn't... I am using Unity 2020.3

[rose sentinel]

OMG it opened on my second monitor.... it was turned off

[deep gazelle]

is there a way to make terrain details not use the healthy and dry color

and just use the original color from their texture

[shell jolt]

Create your own LODs, if you don't have them in the prefabs then the default billboard will be used, thus the ugly colors

Scratch that, I thought it was about tree again 🙂 ...I'm not sure with the terrain detail

[deep gazelle]

Thanks anyways bro

[formal vessel]

Does anyone know of a Tri-planar terrain shader that supports terrain holes in the HDRP?

And no, Microsplat will not work for my purposes.

[deep gazelle]

is it performant to have every texture use normal maps

is that pretty typical nowadays for even basic textures just for low level detail??

[deep gazelle]

also

https://puu.sh/IyykJ/caeaa54d78.png

if all my textures are 128x128 should all these settings be set to 128x128?

what are the optimal settings for this based on the textures

[faint mauve]

is there any way to make the textures blend in better and remove those squares that connect them?

also the terrain res is at max

[desert sun]

have you tried to enable a height based blending in terrain shader? is your terrain textures support height map or have heightmap in one of packed color channel?

[faint mauve]

ok i guess this is a dumb question but i am new to unity so istg i don't know what height based blending is

and what terrain shader you are talking about

u mind telling me in more detail?

anybody knows how to fix this:

[frail vector]

is there a way to make a detail brush that has more that one texture and places a random texture each time? For example I have 6 different grass textures and I would like to use all of them to make the grass look less uniform

[shell jolt]

you can do that from your grass prefab, see below image

to those small grass patches just assign different type of grasses

just be creative... otherwise make individual prefabs for those grasses so you can scatter them manually

[frail vector]

is there a way to do it with a brush though?

[shell jolt]

wdym?

[frail vector]

i mean that there is this brush that you can use when wanting to place some grass. (Its location is shown in the below image). But it only allows me to use one grass texture at a time. I was wondering as I have lots of variations if there was a way that it could place all of them instead of just the same every time.

[clear plank]

Have someone managed to get the new Terrain Sample Pack (https://blog.unity.com/games/the-latest-unity-terrain-sample-pack-is-here) working on Unity 2020 LTS? Or is it really needed to use Unity 2021.2? In the Asset Store description of the package it says that Unity 2019+ is supported, but I have only been able to get it working on 2021.2.

[rough turret]

got no clue how this works, but im makin procedural terrain but i want it to stay in the editor while the scene is stopped, is that possible? also when my mesh terrain is generated, my character just goes through it which doesnt make any sense bc i added a rigidbody and a mesh collider. the mesh collider gives me an option to add a hitbox but i cant make it the same shape as the mesh 🤔 is there a way i can give the mesh a perfect hitbox and make it visible while the scene is stopped?

[somber quest]

How is the mesh for your terrain generated?

Your Mesh Collider Component use a plane mesh

[rough turret]

i followed Brackey's tutorial, it uses points to make a grid, fills the grid with squares made of triangles, then overlays a noise map.

[somber quest]

ok i looked up the video, i think it was the right one. I think it should work if you assign the mesh var in the start routine to the meshcollider after the UpdateMesh() call

GetComponent<MeshCollider>().sharedMesh = mesh;

[tough laurel]

im not sure if this is the right channel but what would be the best method of creating terrain in 2d

and creating hitboxes for it

[warm isle]

I'm new to unity , i can't place brushes (it says "this brush is read only" ) , what should i do ?

[rose sentinel]

ig u have to make a brush tool first

[warm isle]

Ok

[rose sentinel]

use this after create

[warm isle]

But im Not at home

But thanks

[rose sentinel]

oo lol

[rough turret]

its still the same :/

[rose sentinel]

u also have to assign it in the terrain data thing

[warm isle]

Ok

But Blender is better right?

[rose sentinel]

for making 3d modle its better such as building ,props , character , and animation many more but for terrain i prefer unity terrain system

blender is very usefull

[warm isle]

Ok

I already have it

[rose sentinel]

nice

[warm isle]

And for roads?

Blender or?

[rose sentinel]

many ways to goo about roads
u can use some mesh on the terrain
u can make map in blender too and then export it into unity

[rose sentinel]

for making a terrain just use unity

[warm isle]

Ok

[rose sentinel]

it haslots of cool feature

never tried terrain stuff much tho xD

[warm isle]

Ok

Is it hard to add Multiplayer into a Game?

[rose sentinel]

there are 2 ways to make multiplayer

2nd is make ur own server this one is complicated thing xD

[warm isle]

Ok

[rose sentinel]

but there are tutorial's for multiplayer of dedicated server which u can follow and do easily and also for photon or other multiplayer type

[warm isle]

Ok

[rose sentinel]

with photon or mirror u can setup multiplayer in 1 day only

Has anyone seen this error and know what a possible fix may be? I have a minimal project with no terrain assets in it, I've just added the terrain package and that's all. This is on 2021.2

[inner inlet]

I figured out the issue with the trees!

[past relic]

is there any way to quickly mirror objects around chosen axis?

nvm, negative scale did the trick

sooo, is there any way to quickly randomize all those objects with different objects/materials?

I have 3 more types of floor tiles and I simply want to randomize it a couple times

[shell jolt]

This would mess up later on if you have some logic to rotate, scale etc... you must change this from 3d software instead.. but it's up to you

[shell jolt]

Making your own scattering tool to randomize the materials is not hard by any means, either way, you can't randomized the material with the terrain editor

oh wait, you're not talking about terrain editor weren't you 🥲 .. my bad

[past relic]

what about local coordinates? I feel like they already mess up when I put objects inside of object

[shell jolt]

It shouldnt if you have a proper world origin setup

It should follow the parent

The origin of the child should be based of the parent

This simple matters can be tricky to understand thh 😀

[past relic]

no I mean, I do understand relativity of coordinates. But I just don't get this:
Parent object XYZ all 0
And it's child, XYZ also all 0
Why pivot is somewhere else

ok, it was center of object, not actual pivot

but now I don't get this:

why progrids drawn grid like this

meanwhile object is exactly square

with 6x6 dimensions

[hardy kindle]

These trees are made using the inbuilt unity tree editor and placed using the terrain tools. The project is in HDRP. Why are the trees that are converted to billboards being both invisible and also showing up as this white ghosting when viewed at a particular angle?
The console log displays a warning regarding the tree shader but using the shader it recommends causes the trees to display as just purple. They are currently using HDRP Lit which displays properly when not billboards.

How can I fix this so it still displays in the HDRP scene?

[shell jolt]

With all respect, sorry to say, you still don't get it unfortunately 😃 ...

Like I said, it all based on the origin of the object(either the parent or child), in your case, it should be your child's origin is not at center

[past relic]

actually I got it xD
Took a while to realise that progrid doesn't adjust grid to local coordinates

[warm isle]

how to fix this

[warm isle]

fixed

[mellow agate]

So, I know nothing about terrain and environment creation and I'm looking for a starting point. I'm guessing I need to know, roughly, about

1. creating a 3d model that has the rough topological terrain - a heightmap, I guess is the word?
2. generating stuff that makes that model visible (a mesh, trees, textures)
3. slicing up a large world into chunks so that it can be efficiently loaded during runtime

... does anyone have any notions about what I might start looking at to break into this topic?

like, some initial questions, what kind of data format is scene geometry generally stored as? is it a series of 3d points or is it 2d points plus height data? is it a standard format for most modern level modelling applications or is it proprietary for different tools?

[past relic]

Is there any way to get total dimensions of object or at least visualise it? I want to somehow fit without having to guess scale

[past relic]

you can simply look up ready assets and look at what they have (or what their prefabs are made of)

[mellow agate]

Alright, did that, figured out that its generally a grayscale image for a heightmap.

So now, I have what is probably a hopelessly abstract question, so I'm going to ask it in the form of my love language: a shitty MS paint diagram.

so basically I have a question about downsampling complex meshes in a way that preserves important qualities of the overall image.

in my case, I have a huge map of antarctica taken from satellite data that I want to ______ (I don't know the word). I want to smoosh it down to a lower level of detail that still preserves texture in important places in the terrain, whereas simple bilinear downsampling would produce a kind of smoothing effect

so, imagine a hypothetical line, lets say it represents a mountain chain or a coastline. it has areas that are jagged, almost serrated and areas that are smooth

if you just did a basic downsampling, you'd average out the peaks and valleys of jagged features and would kind of lose them

whereas it would be preferable if the final product still had those jagged featues with the same salience, but just fewer of them

so like, preserving feature salience when downsampling. I don't know if that has a word in terrain design / world building, but if so I want to know what it is and what strategies people have used

for some context, I have this ~5000x5000 grayscale heightmap of antarctica from satellite data. you can see there are some jagged features and coastlines in certain places along the southern edge and northern edge, etc:

naive downsampling this would create less satisfying/natural geometry details along those jagged coasts

[dire badger]

My trees disappear very quickly when i zoom out. I have LOD set and the tree distance is at the maximum. Why do my trees disappear so fast?

[thorny swift]

Why do you want downsample it, Antarctic is big so you would have to use multiple terrain's, just cut it into peaces and import into terrain grid?

[heady estuary]

Is it a meme that terrain performance on mobile is bad ?

[rose sentinel]

how plz

[warm isle]

Redownloaded the asset

[rose sentinel]

I see

thx

[mellow agate]

ah, see thats a really good way of accomplishing that. so thats why I said I don't know the right vocabulary for this - downsampling isn't quite right because it excludes other mechanisms of accomplishing the same thing, like what you just said

[thorny swift]

Yeah understand that

[rose sentinel]

Isometric pixelated game. How do I make it so players can go behind a sprite if they... go behind it? and infront of it if they're infront of it?

[smoky ivy]

Does anyone know of a similar system/technique as that shown on the Unity Blog regarding terrain systems as part of the Algoryx Unity solution?
https://blog-api.unity.com/sites/default/files/2021-12/terrain.gif

[quick schooner]

How do i convert this into terrain ( mesh ), online tutorials doesn't help me

[thorny swift]

looks kinda like voxels, when he gets into contact of "ghost" aka point that has a value it converts it into a particle which is then added a physics, while updating the mesh with just ghost points and when a particle stops moving it is then turned into ghost particle and calls the terrain to regenerate mesh.

[thorny swift]

https://www.youtube.com/watch?v=bFGXghavsD8

[quick schooner]

not working

it said something like TerrainToolbox: Heightmap resolution per tile is not square size with current settings.
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

[thorny swift]

Yes, you need to cut your texture into 1:1 ratio, so 512x512px or 1024x1024px etc. it has to have both sides same

[rose sentinel]

are we supposed to bake terrain shadows?

or it is to big to be baked

guys when i brush the terrain the height is more then what i expected , how can i reduce it

[analog basin]

i cant walk any further, there are no colliders that i will colide with and the slope limiit is 90 degrees. Anyone knows a fix?

[burnt ermine]

Hello, I was wondering if anyone has experienced something similar with terrains and know a solution. As shown in the attached image, I have a capsule with a rigidbody that is pushed to a location. When I push the rigidbody is pushed up on the hills of the terrain (as it should) but many times I experience that the rigidbody will clip trough the terrain. For now I just have a script that teleports the rigidbody up to a higher y value if the y value is below some value. This solution are not really sustainable. Any tips for how this can be improved? I might suspect that the terrain might be to "uneven" can this cause problems?

[burnt ermine]

I have also tried to tweak the rigidbody collision detection without any difference

[soft meteor]

does anyone know how to incerease treee render sdistance

[warm radish]

heya. what are you using for the player controller you have? and what is your terrain setup like? multiple terrains, are you using again plugins/asset packages, etc

[analog basin]

Hello, I used a player controller form brackys on yt, but changed the movement. Also I just use the terrain of unity, and I am multiple plugins. But it wors fine in the rest of the map.

Only that area acts weird...

[warm radish]

based on the inspector contents in the video, looks like the mesh collider for the generated terrain is a plane. can you provide more info on why you cant make it the same shape as the generated mesh?

[warm radish]

do you know if you are using nav meshes and if the brackeys character controller makes use of them as well?

[analog basin]

I did use a navmesh agent, but can't say it for sure. Don't have acces to my pc right now.

But I did use navmesh

[warm radish]

ok. i'd check to see if nav mesh is generated in that area. maybe it isn't?

[analog basin]

Didnt use normal walking but used animations for walking 🤣😂 because it was easier to make

[analog basin]

Aaaah good one, didn't think about that. U need to bake that right? Ty

[warm radish]

yup! when you get the chance, check that out and let me know what you find here in chat

[analog basin]

Ty, also baking takes a few minutes but I have the time. I'll let you know, probably over 2 days or so.

Have a nice weekend, cya

[warm radish]

thanks. you too!

Question: I have Gaia 2, would The Vegetation Engine be able to work with it? I am wanting realistic grass\tree movement.
Side note: or would it be better to go for the Gaia 2021? or both?

[rough turret]

when i click the mesh option in the mesh collider, it doesnt show me my mesh which ive seen in other tutorials. im thinking this might be because im procedurally generating it

[warm radish]

in your script you'll probably have to get a reference to the MeshCollider with GetComponent and assign your generated terrain mesh to the MeshCollider

[rough turret]

im new to unity and C# so i have no clue how to do that lol, and since i sent the original message, 6 days ago, my pc is broken :/ i cant fix anything rn

hi guys! How can i make textures less tiled? I saw some tutorials in blender but i am not familiar with it. Are there any ways to do it in unity? Maybe some plugins?

How can I make my terrain have a pixel art texture? I'm using probuilder to make my 2.5D terrain.

[desert sun]

its called z-fighting when surface of models align with each others. try to learn blender 3d for creating primitive levels without z-fighting

[hybrid briar]

uhhh hey guys - is there anyway I could like

flatten terrain but at an angle

[hybrid briar]

kind of like this a bit, finding it hard to micro manage the different bits of terrain

flattening it and such without making it dead flat

[scenic dome]

Alright so im trying to find a quick fix to remove z fighting without really changing the scene around, anyone know a way to to that?

nvm fixed it

Anyone know if there's a discord dedicated to MapMagic2? would be great to discuss with other people using it

[cosmic pollen]

yep this is exactly what i want

[shell jolt]

now google it! 👍

[cosmic pollen]

but is it only work on terrain?

[shell jolt]

uh, no.. everything in worldspace

[cosmic pollen]

oh okay

[rough tusk]

Does anyone have an idea on a colour scheme for the back planet so it contrasts well but doesnt overwhelm?

[deep gazelle]

Any color would do just adjust the brightness so its appropriately in the background

[stuck epoch]

Does anyone know how to translate noise into height. I don't need that specifically but there is something else, that I want to do with this

[rough tusk]

How's this looking? Been working really hard on it.

[deep gazelle]

That looks amazing

Nice job

[analog basin]

sorry for late reaction, i baked it but doesnt work...

cant walk any further, iam blocked there. no collider or someting

[warm radish]

👋 heya. what happens if you have a large plane there on top of the terrain. are you able to walk on that?

[analog basin]

Heya, I'm now in bed 😆 will try again if I have the time.

Ty for responding, have a nice day

[warm radish]

ok haha. will talk to you later!

[rose sentinel]

How do I assign something as Terrain?

[modern wolf]

why is my terrain not rendering when i enable path tracing?

[sharp meadow]

How can i fix the height?

[drifting crown]

@sharp meadow This is the appropriate channel. To get an actual answer you should provide relevant details. Whatever method you are using to import height map, normalize it to the range, if it hits limits.

[sharp meadow]

Can height limits be raised? I imported heightmap with Terrain toolbox. I entered the parameters provided by https://heightmap.skydark.pl/ from here I also took Heightmap

[drifting crown]

You need to examine the data and see how you can reduce it to the limits.

Or find a tool that does it.

[sharp meadow]

What is the maximum height limit?

[drifting crown]

Not familiar with Terrain system. Usually it's 0-1

You'll get that from testing the data and debugging results.

[last linden]

Tree 001 is the Bark
Tree_1 is the leefs they both have separate mesh renderers

i have a LOD group

but i still have this problem of the tree loading only the bark

when i paint with terrain brush

The tree is made with Tree It

[analog basin]

doesnt work lmao

[analog basin]

found the fix

[warm radish]

nice. what was it?

[analog basin]

Dunno

[shell jolt]

you can do cross-quads for the grass so it would look a bit nicer. Or just circular pattern for variance. either way, it looks good! 👍

[last linden]

unity terrain built in grass tool is also decent if you disable billboard and have a good looking PNG grass

[latent torrent]

The terrain tree paint - does it only allow prefabs that have one root element that has a mesh renderer? so if I had a prefab that consists of 2 meshs (leaves and the trunk) as a child, do we expect the tree terrain painter to work?

[shell jolt]

it should work, yes

Use Blender or any 3d software you're familiar with

[latent torrent]

Is that reply to me? about the terrain tree painter painting prefabs of this structure:

parentContainer (no mesh)

• child1 container (with mesh and mesh renderer) - eg. the leaves
• child2 container (with mesh and mesh renderer) - eg. the trunk

It doens't seem to work, doesn't end up painting anything, although I can select the prefab as a tree - just doesn't do anything.

[lapis wave]

this brush of mine has a different shape and effect than the one in the tutorial (below) even though they are the same brushes, any ideas?

mine looks like a football, is full round

^also gives shape as a football

[shell jolt]

Check if the origin of your object is centered and at the botom of the trunk... bcos if it's not, it will be spawned anywhere based on the object's origin even below the terrain

Either way, Unity would complain in form of a warnings in the editor's console if it doesn't meet the requirement

if there's no warnings, then most probably it gets spawned outside the terrain, like way above, below or anywhere else bcos of the object's origin I mentioned

[merry snow]

hello can I ask about 2d here?

[warm radish]

it might be that they are different versions of unity and terrain tools package? i know we changed some of the brush preview code between releases so that might explain why the brush shape itself looks different. for what it's worth, the top one looks like the correct preview to me.

as to why the painted results might be different, maybe it is due to heightmap resolution. the terrain from the bottom picture looks like it has a higher resolution heightmap than the terrain from the top picture. it might also have instancing enabled. i recommend heightmap of at least 2k to get decent results with the hydraulic erosion tool

and to enable instancing, enable "draw instanced" in the terrain's settings tab of the inspector

[sinful tree]

Does anyone know how can I use google maps as a game terrain?

I mean, I only need the 2D terrain

[left steppe]

Hello im having trouble with terrian toolbox I followed the instructions https://docs.unity3d.com/Packages/com.unity.terrain-tools@2.0/manual/toolbox-import-heightmap.html for batch importing but no matter what I do it only thinks there 1 x 1 tiles? my folder has hundreds named correctly but even if I tried to mimic the example it doesn't seem to find the 2x2 grid. I can load them up individually anyone else have this issue?

[molten dagger]

Hey guys, I'm working on some procedural planets. I got some mad issues with the normals. they are so close to displaying correctly, yet they aren't

each triangle is a separate mesh where every vertex of a triangle shares the same normal/tangent, with the normal pointing straight out from the triangle and the tangent matching the x axis of the texture

the world normals when i draw to the texture represent a perfect sphere, and I've debugged them in multiple ways by drawing them to the regular texture, it all looks good and seamless

but when i put it on the normal map, this happens

This is how i draw the normals

// Texture settings
                Texture2D normalTexture = new Texture2D(texSize, texSize, TextureFormat.RGBA32, false, false);
                normalTexture.filterMode = FilterMode.Trilinear;

                // Per pixel on the normal texture

                Vector3 tangentSpaceNormal = new Vector3(
                    Vector3.Dot(objectSpaceNormal, tangent),
                    Vector3.Dot(objectSpaceNormal, bitangent),
                    Vector3.Dot(objectSpaceNormal, normal)
                ).normalized;

                Color normalColor = new Color(
                    tangentSpaceNormal.x * 0.5f + 0.5f,
                    tangentSpaceNormal.y * 0.5f + 0.5f,
                    1,
                    1
                );
                normalPix[i] = normalColor;

I have tried playing with those last two boolean parameters to rule out srgb troubles and such, but it makes no difference

[molten dagger]

Sorry for crap video but this shows the issues quite well i think

For example on the back half of the sphere, the light intensity is almost black in some corners, which is weird since its supposed to be unshaded

[molten dagger]

Been spending way too many hours on this. Maybe I should just write my own shader that can handle object space normals

[cerulean skiff]

Question which might be obvious and I'm missing it, but how do you create LOD for Unity Editor created trees? The documentation says the extension takes care of the LOD, but I can't figure out how to enable that function. I need this to work because whenever I paint the trees, they're all the same orientation. In order to enable random rotation, it seems that you need to enable the LOD group.

[lost field]

If i got a basic terrain and i just want like a rectangular hole in the ground, is there any way I could just make a cube and have it cut the cube out of the terrain? Sorry if this is explained poorly, this is my first time using the terrain editor

[rose sentinel]

Oh god, I use 2020.3.20

Were same using that version

[latent torrent]

Turns out there was a warning, but it only appeared if you clicked "refresh" on the terrain paint trees tab, not if you try painting with it. The error is:
The tree treeModel couldn't be instanced because the prefab contains no valid mesh renderer.
Due to my prefab containing the tree (leaf and trunk) meshes as child objects - I can't use it as a painter.
So that means the terrain tree painter cannot paint anything that has more than one mesh, dang.

[shell jolt]

Save your headache, and use this https://github.com/Whinarn/UnityMeshSimplifier/... Add the LodGeneratorComponent to your prefab and follow the instruction...

once generated, it will pool all your mesh renderer in one place(parent) as if it's one object (but it's not)

Your issue is pretty simple, and don't require to use that tbh... but to save your time, just use it

I used that almost in all my 3d projects..

[latent torrent]

wow, very neat! Sounds like it'll do the job, I'll give it a try

[shell jolt]

Note: Read the WIKI

see the DOs and Don'ts

Turns out there was a warning, but it only appeared if you clicked "refresh" on the terrain paint trees that sounds like a bug, you can report it if you want

[cerulean skiff]

This might be a fix for the problem I was having as well, but I can't get it to install and I'm too nervous to mess with the manifest.

Is there any performance benefit when spawning trees with Terrain system?
Or I can just spawn them as gameobjects with no performance overhead?

[shell jolt]

No, no magic or anything, just pure convenience

you should make/manage your own LODs to get the most of it

[latent torrent]

Have to come back here and say what a fantastic recommendation - this LODGenerator is amazing.

[shell jolt]

Yeah, I've been using it a lot in my project... and quite simple to use out of the box

You can go beyond the default, it has a built in apis for culling states, the package is very powerful if you're doing it from code... just saying, you don't have to do this

Btw, Unity has a similar implementation to that officially (a work based on MeshSimplifier as well), but it quite stale at the moment. No reason to switching to that

[wild sable]

Yo guys, how can I fixed tree collider doesn't work on my terrain? I've already add collider to my tree but it still doesn't work at all

Btw I'm using terrain tools package

[shell jolt]

Define not working!

how do you know they are weren't working? What if,... and what if... it was your collission code that caused it not to work?

or your setup in general...

[smoky vigil]

Does anyone know of a good way to make an environment with elements? Think Breath of the Wild. The world is stored in mesh parts but how does the game know where to put trees and what kind of tree to put and how to angle or position the tree? I was thinking of exporting a model with several empties to show where everything should spawn but that sounds tedious and potentially not good for the FPS

There's also the fact that Unity itself can load scenes and a scene can just consist of your terrain and foliage but I'm not sure if that's a good idea as well

Trying to work with optimization and well, a better way to do this

Alright, I believe what I'm looking for is Subscenes

[shell jolt]

If you know how to do c# placing trees based on certain coordinates based on certain condition of the terrain wouldn't be too hard, even I personally think this is not the preferred way if you're looking for perfections

Hello my custom made tree doesn't have a bend factor when adding it to terrain tree brush

Don''t count me on this, google it if you'd

ah ok i see so i'd better just use shader graph to simulate wind ?

for the trees at least

and grass i use wind zone it works well

[elfin inlet]

🤔

Try to decrease again ?

[worldly forge]

this is more a question of concept than actually asking for help, but how feasible would it be to generate a world made of premade chunks, but using like vertex colors to designate what tiles could be built next to the previous.

example, like 2 corners of a hexagon that would be a premade chunk of terrain and is raised like on a hill and have a color or value based on the height and have the adjacent tile not generate unless that point shares the same value.

asking here since it's more asking opinions of an idea

[floral sand]

Not everyone has a solution to you specific problem, my tip is to troubleshoot, make a new project solely to create the terrain and do the grass painting, I'm not well versed in Unity Terrain myself so I can't give you more directions other than help you understand the steps of troubleshooting.

1. Make a new project and try to recreate the problem

2. If the problem doesn't exist in your new project, check what's different, something it bound to have changed.

3. Google is great, Discord is not the only resource.

4. Don't dig yourself in a hole, if something doesn't work you can try to solve it or simply take a completely different approach.

Your problem doesn't sound all too complicated however, I'm sure you'll solve it. 🙂

If you go too small or too big, the coordinate system will run out of accuracy to represent objects

Does anyone know how to get tree color variation working? I made a custom tree added an LOD group and rotation and height work but not color? Can't find a tutorial on it

[tame raven]

Hmm, I guess you could just add some different prefabs on the Trees list, using the same tree mesh but with different materials.

||If you want to make use of only one material for better batching purposes, you can think on a complex shader that changes the color based on something like it's position in world space, for example.||

Yeah I gave up trying to get it to work, So I just added 4 different shades of the same tree.

Also start with compiling a bunch of references. You can use a program like pureref to organize it.

[lofty fjord]

Are levels best made in blender so that you can better blend models in the scene?

[undone lark]

You use a combination of terrain and models. Or, if it's an interior, just models. How you make those models are up to you.

The fact Blender is called that isn't an indication that it's good at "blending" models into a scene. That's up to you and your ability to make it look that way.

i tried adding a texture to my terrain, but this is happening. can someone help me out pls?

only after zooming in is it visible + it's not getting applied to the others

[winter minnow]

@prime stone Check scene's fog settings

[prime stone]

where do i go to check that?

[winter minnow]

Lighting window > Environment tab
It could be controlled by post processing if you're using PPs2

[trim cliff]

the player is no supposed to fall when i have freezed position but it does what to do?

does anyone know how I can cut a hole in my terrain?

[winter minnow]

[jade minnow]

I can't add water from the standard assets to my project, both Basic Water and Water (pro) give compiler errors. I'm using HDRP.

...
Well, I assume it's the water. I'm getting the error 'All compiler errors have to be fixed before you enter playmode'

I don't know how to view compiler errors. Are these just the errors in the console? If so, they are hardly anything I can fix, it looks like it's up to Unity to fix these things.

None of them seem relevant to my project. Stuff about GUI.Text being deprecated etc. I'm not using text. Various other issues with shaders and Speed Tree etc. Nothing used in my project.

[prime stone]

sorry for the late reply but thank u!

[dusky ivy]

Hi, is there any way you can create heightmap png file from a terrain created in unity? The idea is to create a terrain in Unity and export it to an OpenGL project

[winter minnow]

https://docs.unity3d.com/Manual/terrain-Heightmaps.html
Instructions how to export here
Raw files can be converted to png using various image editors

[dusky ivy]

Hi, again. So I am having this issue that im not sure how to deal with. I could export the raw file and convert it to import it to my OpenGL project. I'll show you a couple of screenshots that would explain the issue by themselves.

so, that's the terrain ive done n Unity and here is the result in my other project

does anyone have any tip or would recommend any other tool?

[rare night]

Y reversed?

Not sure what you mean

[dusky ivy]

well, the heightmap i got from unity is been imported to my other project and the difference is quite interesting

the height is clearly different and i dont know how to fix that

[rare night]

Probably don't have correct y max as well

Hard to tell though

[dusky ivy]

do you mean on the unity editor? Ive changed the mesh height and the output has been the same

doing this does not make any difference in my other project

[rare night]

Right, height is mapped the same. The height there is essentially just a multiplier in unity

Height is encoded 0-255?

[dusky ivy]

8 bits, yes

[rare night]

So center is flattened?

(in opengl)

[dusky ivy]

well yes the center is flattened because in the unity editor is flattened too. Ive tried to a kind of volcano

the issue is more the height of the volcano

and also the perimeter that limits the terrain

[rare night]

Are you decoding the image in srgb?

[dusky ivy]

grayscale

[rare night]

Perhaps color space is causing issue. Kk

Was thinking gamma correction but I'll stop guessing now. 😉

[pure matrix]

Guys, when i try to convert my terrain from HDRP to URP everything become pink, and i cant convert the material bc he cant use the terrain material

[winter minnow]

It's all about the encoding from raw to png
There's no one to one way to do it so the values can change

[winter minnow]

Is the terrain material's shader from HDRP or some external asset?

[ripe elm]

Hey can you help me how to make 3D Hex tilemaps? I have some issue

size does not match and not the center

[pure matrix]

ye its from hdrp

[winter minnow]

If it can't be converted then I guess you could switch the material to URP terrain manually

[pure matrix]

i tried it but now everything are black

i'm trying to use a URP>Terrain material>lit

[haughty kernel]

What to do so that the tree does not change its quality over the distance?

[pure matrix]

change the LOD
like this

[haughty kernel]

Where can I find LOD?

[pure matrix]

where u tree are

you tree should be a LOD

[haughty kernel]

Ok, thanks

[pure matrix]

i solved it, was a wrong settings on the light setup

[jade minnow]

In order to paint grass, the docs say to Edit Details / Add Grass Texture. But that is grayed out.

[jade minnow]

I've tried to Add Detail Mesh - but it crashes Unity when I start painting. It looks like it's painting very densely. In the Inspector...

Detail patches currently allocated = 4096
Detail instance density = 16 million
Those numbers don't look right to me, but I have no idea.

[warm radish]

heya. if i am remembering correctly, the detail patches are along each the x and y axis so 4096*4096 = 16,777,216.

[jade minnow]

So how can i change the density?

I've set brush strength to 0.0625 (minimum value), and it paints the grass as densely as you can imagine.

Sometimes when I'm painting or erasing details, the Scene View goes blank, but if I zoom out I can see the terrain again, although the performance is bad (jerky). Any idea what's going on?

I have this error - which I always see - the index 44 error ...

[halcyon patrol]

The density of your details and trees is also controlled by your

Terrain Scale
Detail Resolution per patch
Detail Resolution
Brush Strength and Brush opacity

If you have a terrain that's much smaller than the detail Res and patch size for example, you'd have a lot of density overlap like this.

It is a really confusing balance to make in all honesty.

But I'd try finding a good balance with your brush Strength/ opacity and Details Res/patch

[jade minnow]

@halcyon patrol OK, the balance is very important then. I made a much larger terrain, and it was immediately more natural - a splattering of grass instead of a dense clump.

[halcyon patrol]

Yup! Absolutely.
As a general rule, I try to keep my details resolution at least double my terrain tile.

I get a good brush balance and natural density from the texels of the details maps size.

Details resolution per patch can also increase density at 128 and perform better in some cases, but there is a balance point there too.

The downside of painting by hand here is it's very easy to overlap meshes without knowing.

If you use "Terrain Tools" and also the asset store add on for it.
You can a few more options that may help you fine tune broad scene wide strokes like the texture/noise filters.

Over all, I'll be happy to witness the terrains in general get a large overhaul to allow better control for "larger and smaller brush strokes".

For the most part by default we use a procedural Spawner with rule sets to Spawn the initial ideas and then go in by hand or volumes. For much finer details.

[supple roost]

is this the right place to ask about tiled stuff?

[jade minnow]

@supple roost I think so, as in a 2d tilemap? It's not really terrain, but it's pretty close.

...

Tiles X Axis = number of tiles along x axis
And Unity's default values are 1 for X,Z axes ... wth!!

Is that just bad configuration, or does Unity mean something different when they say Tile compared to what everyone else means?

Because for me, a tile is a logical region on the grid that is navigable or for terrain purposes it could represent a quad of the terrain. I can't think of any interpretation of tile that would result in a 1 x 1 tile over a 1000 x 1000 m terrain.

Further, the terrain toolbox even says that I can assign a heightmap to an individual tile .. that doesn't even make sense.

Does Unity mean chunk when they say tile?

Also, I'm trying to import a heightmap, it's resolution is 501x501, my terrain details...

Size = 500 x 500
Tiles = 10 x 10

But I'm getting an error the inputed heightmaps resolution of 52 x 52 does not match selected heightmaps resolution. The generated heightmap will be resized to 513 x 513 ... ahm, these numbers don't match anything I'm using.

[jade minnow]

Another question, I've changed the material on my terrain, but nothing works. I was looking to apply a single texture to the terrain as a base texture or replacer for splat map.

How can I restore the material to the default material? There is no option, just a big list of materials. Even choosing New Terrain Material doesn't work, it says 'The provided material's shader is unsuitable'.

[quaint mango]

if the terrain is broken in my project (and i know it is cuz i tried another project and it worked), is there a way to fix it or do i just have to upgrade my unity version?

I'm using 2021.1.22f1 and the terrain tool won't let me use trees

i opened a 2021.1.4f1 project and imported my trees in there and they worked just fine

oh yeah and i made a second terrain to see if it worked and it did not

[dreamy trench]

Hi folks, I'm having trouble with the terrain that I draw using the Unity terrain editor looking extremely bumpy. I'm also using Microsplat and contacted the creator about it but he doesn't believe it's related as he doesn't do anything with heightmaps and I don't have tessellation on. The only thing I seem to be able to come up with is having to do with 8-bit and 16-bit heightmaps, but I don't see how it could possibly be a problem since this isn't an imported heightmap. Any ideas?

Thanks in advance!

[serene summit]

Hey folks, I'm having an issue with the smooth height of Unity's terrain tools. It was working fine a day ago, but Unity suddenly crashed on me. Now when I try to use any smooth height brush, it will work as intended the very first time I click on the terrain and after, it will smooth the terrain further out on the forward vector of the brush's position.

I'm trying to smooth the terrain in by these canyon cliffs that I made and the terrain is instead smoothed around the canyon's cliff peaks. Also, I selected a separate brush once and the smooth height brush stayed in its former position on the terrain. Anyone have a clue as to what's going on here? I tried using Unity 2021.2.2 and upgrading to 2021.2.12 today. Nothing fixes the smoothing brush.

As full disclosure, I'm also using Gaia Pro 2021, but I've had that in the project for a long time and this is the first time I've ever encountered this problem.

[still bolt]

Hey guys, I'm new to Unity and I'm sorry if this question sounds very stupid, but how can I rotate the terrain brush? I've been spamming and holding D based on what the docs say, but nothing seems to happen

[willow parrot]

I'm trying to create a terrain system that's procedurally generated that create planets or at least the illusion of one like in astroneer but i don't know where to start any tips on how i should tackle this or where to begin (never made a terrain system before)

[balmy dove]

Excuse me!
Who can send a water object for me?

[stone hull]

Can you send an screenshot?

[undone ibex]

Not possible at the moment

[stone hull]

you're probably looking for "procedural terrain generation"
try googling it, there are many resources online about that topic

[willow parrot]

I did and found a video on it but it generated flat terrain and then I found one for a planet but it was just a small one without a chunk system

[summer latch]

Im using a terrain (HDRP) and try to put some cubes down with a sand material with the detail feature. While they are not pure black, they are super dark. Does it not work with real time lighting?

[stone hull]

You probably need to upgrade your material. Google "How to upgrade materials for HDRP"

[summer latch]

I found a solution if some1 is interested: https://issuetracker.unity3d.com/issues/terrain-details-become-very-dark-when-light-layers-are-enabled-in-hdrp Disabling light layers for now fixed it for me :)

[cosmic comet]

Would anyone know how i can reduce drawcalls on Terrain and its objects?(Like trees and grass) I already use Gpu instancing but the terrain keeps giving me 150-300 setpasses.

[rose sentinel]

Is there a way to make the terrain grass work with the 2D renderer?

[tribal gyro]

I am baking with Bakery and I have a terrain in the scene as my floor because it allows me to paint textures.
Terrains are weird with baking with Bakery so I need to create a model that has the terrain's splatmap on it, how would I do that?

[shell jolt]

Read the requirements of how instancing work, also profile it and see which of those prefabs for grasses or trees that aren't successfully instanced, the profiler will give you a clue what was failed and what not

Also note, gpu-instancing doesn't play along with srp batcher

[cosmic comet]

I red that, but does the srp batcher not work on terrain then?

[sinful star]

Yo guys, I'm planning on doing a big af terrain on unity and I'm not that confident about it, so I'm looking for all the suggestions I can get, like optimising the workflow and how to, like using specific tools ecc.
Thaks in advance to everyone.

P. S
I know that one tip would be don't do it by yourself because it's too much, but I can't pay anyone rn, bit sad, plus it's part of an actual project so...

[shell jolt]

How big 'af' the terrain would be 😀 just make youself comfortable with the super-simplistic-barebone unity terrain editor 1st... Doeasnt matter how big the terrain will be

[sinful star]

i'm use to the terrain tools for small scenes, but it is actually a pretty big map i want to do, like 100 km on one dimension, im doing this also to explore the optimising tools unity offers that im not that familiar with, like streaming, subscenes ecc

note that is a stylized tipe world

type

[shell jolt]

You dont need that big of a terrain in one go ..split them into chuncks

[sinful star]

yes at the master i0ve done i've been told to use chunks and streaming together

[shell jolt]

The super-basic-and-barebone unity terrain editor has a feature to stitch multiple terrains

[sinful star]

the thing i'm worried about is to set up all correctly before placing any terrain or i'm afraid i might have to start all over for some minor issue

cause connecting a lot of terrain might actually end up like christmas tree lights, you broke one and all broke after

do you perhaps know a guide that can help me start all?

[rose sentinel]

if i create a layer and i will select it in editor i became the error : ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection. What can i do ?

because mesh looks way better but uses a lot of resources, and billboard looks decent but if you look at it from top down

you get this

anyone has one free premade forest for unity? thats all i need right now. i dont know how to make forests

People rarely asked for a complete forest (as in completely done forest), rather what's in the forest such as; trees, grasses, flowers etc...

Sketchfab is the way to go

or even assets store

hello

can someone help me please

i cant place grass or trees on my terrain in hdrp

why is my mesh terrain looking like this

i want it to look like this but i don't know what is causing it to look like that

[thorny swift]

Check if you have Int somewhere where there should be float, it looks like it getting floored, maybe even when using lower than 16bit it could have similar result

[rose sentinel]

Ok, i'll check

[vapid cairn]

why doesn't my layer get added to the ground?

[ashen verge]

would water related questions go here? bcs im looking for some tutorial for making water and infinate amounts of it

[vapid cairn]

meh, i dont think so

[thorny swift]

You have to use Terrain compatible Material to use Terrain Layers

[vapid cairn]

i figured i had to get the awnser myself after looking at the relevancy of this chat, but thanks xD

i got it working :)

[thorny swift]

yeah, its not most active one 😄 np 😄

[spring swan]

Is there a reason why the brush strength on the terrain is way too strong? It's set at 0.174 and a single click on the terrain rises up so quickly

[shell jolt]

your resolution is not high enough, but I do agree, it should behave the same for both low and high resolution

[dry maple]

Im working with a terrain generator that ill probably have to modify further, but right now it generates fairly uniform patches in a smooth elevation gradient, which is desirable but Im looking at doing this in layers. thoughts on how i might approach this? i can send code if needed.

Im thinking of sorting the tiles based upon z position and then putting them into a tilemap per layer but based upon how the code is right now im not totally sure how to approach this. maybe a list of tile maps where the index is the height? idk.
