[winter minnow]

Yea, I don't think having prefab hierarchies adds any cost
Does save you time, though

[strong fox]

I think I'll take your advice, and make a couple prefab variants decorated differently for each building and then throw in a couple non-parented prop prefabs sprinkled around the scene.

Thanks so much for the advice!

[ivory mauve]

I did what it told me but it doesn't work

[winter minnow]

That means you reduced vertices? Does it still give an error about too many vertices

[ivory mauve]

I did the reduce detail and it still gave me errors

[winter minnow]

About what, too many vertices again?

[grizzled wigeon]

Why is it that terrain tools is not appearing in the windows tab? I want to create new terrain without using 3d objects.

because my terrain is turning up like this on 3d objects:

[rose sentinel]

I'm a beginner so I don't know if there is an easy fix or not, but when I increase the tiling option to make the textures smaller it does this:

[ivory mauve]

yes

[winter minnow]

Stands to reason that you didn't reduce the vertices enough? 🤔

[winter minnow]

Confirm that the texture's Wrap Mode is set to Repeat in import settings

[rose sentinel]

Oh thank you!

[woven citrus]

Does anyone know how to make visual brush rendering like that? I am working on trees editor so you can plant them, but idk how to make brush size visual.

I mean i dont know how to make projector following cursor. I can use raycasting from screen, but it is too expensive

[maiden lichen]

@woven citrus you mean a custom brush?

[woven citrus]

It is not connected to terrain system. I just want to make this effect

[maiden lichen]

when i made it for my custom brush tool i used gizmos

its more optimized and much easier to setup

just make ur own gizmo script

[woven citrus]

Can you tell more about it?

[maiden lichen]

you cant use the projector

[woven citrus]

Yeah, i know about projector

But the problem is how to attach it to cursor

[maiden lichen]

yea it doesnt work. i thought of it back then too but it doesnt really work and its less efficient

with gizmos. you can draw any shape on to the editor

and have it work just like the brush you sent a screenshot of

what you gotta do is get the cursors position to world

so screenpointToWorld

and then set the gizmo in a update loop to that position

[woven citrus]

but wait. It will draw in the mouse position in camera, not on the terrain, right?

[maiden lichen]

?

where ever your cursor is. it will draw it there in the relative position

[woven citrus]

If i just make mouse pos global it will be in camera?

[maiden lichen]

i dont completly understand what youre asking.

But screenpoint to world

it gets the position of your cursor. but returns the relative position in world space

meaning the shape would be in the world

[woven citrus]

what exactly does gizmos do? does it draw shapes on screen?

[maiden lichen]

Everything you use in the editor is gizmos

when you drag a cube around

when you rotate the light. those handles that let you rotate are gizmos

[woven citrus]

okay, i'll try it. Thanks a lot

[maiden lichen]

no worries

@woven citrus here's a video with an early version of my brush tool. you can see the gizmo brush i made there

To make sure its what youre looking for of course

[woven citrus]

Wow, yes, that is exactly what I need. Thank you very very VERY much:D

But how did you draw it? I didnt actually see the drawing code)

[tribal canyon]

General noob question. When people build levels from assets and stuff, is it pretty normal for the designer to build the entire level world, and then go back in and redo the colliders for optimization?

[maiden lichen]

@woven citrus i dont have the script showing there but i can send it if youd like

[maiden lichen]

depends. colliders are usually set from the get go with the assets. the only reason you might change them is for gameplay

and usually levels are made and taken care of by the environment artist making and setting up the assets. the idea of a level designer isnt something ive personally come across often but in simple words. The collision is set with the assets, and not really remade after the level is done for any other reason than gameplay

[tribal canyon]

There just seem to be a lot of mesh colliders... also, in the case where a building has 4 walls, you'd reduce it to a single collider on the group, right?

[dim thistle]

Is there any reason to use "Paint Detail" on a terrain? I think I can just use "Paint Trees" for everything (including grass) and it's more flexible

[maiden lichen]

Well mesh colliders in general arent so optimal. Typically you want to stick to box and capsule colliders

But since i dont know much about the game youre making, i will assume it doesnt involve many complex scripts or complex shaders, networking, etc... So its fine to stick with your meshcolliders for now. But in the future when you make your own assets or maybe even use assets that are made for more complex and performance demanding projects, then you can take more time setting up the collisions by hand

But for now as far as my knowledge about the project goes, i think youre safe to just have fun with it and not worry about performance much if at all. Maybe draw calls but not sure as ive already said, dont know enough about the project but you should be fine

[snow current]

Hello everyone! I have this weird problem regarding the trees placed by the tree brush: the billboarding is...wrong to say the least. In the top half, I unchecked the "Convert Units" checkbox because the trees are...so small they aren't even visible (bottom half-Convert Units checked). The billboarding in the second pic may be the correct size, but the trees for sure aren't. I've tried following Unity's warning: to use the soft occlusion shader, but that only makes them pink (might have to do with URP?).
I've tried looking online for any way to solve this, but I haven't found anything. Does anyone know some way I could fix those trees?

[maiden lichen]

I assume you made them in blender. Its the exporting that is inconsistant in that case and needs to be adjusted

[snow current]

yep, they're exported from blender. I had to rotate them already so I wouldn't have them laying on the floor. Could you tell me what am I supposed to modify? the scale was brought to 1 1 1, so uh...might take a while to do something about that

[maiden lichen]

Look up videos on exporting from blender to unity. Its easier than me having to explain it word by word

[snow current]

alright, will do so. I will return if I can't fix it probably but thanks for the help anyways!

[maiden lichen]

All good

good luck

[strange wave]

This is a Mesh Collider question. When I add the matching mesh for this forest ground, the mesh always attaches in this vertical angle. Same for other materials in this pack from what I've seen and tested.

Is there a way for me to separately rotate the mesh to match the position of the material?

When I use the rotate tool, it rotates the mesh and material together. So that's out.

Okay, so what I ended up doing is creating an empty object and added the Mesh Collider component to it. Making it completely separate from the ground material. Duplicated it once and used CTRL to position it incrementally. It works well enough.

Now I'm thinking of how to easily and efficiently duplicate and move the mesh into position while being able to see the unselected meshes as reference since an unselected mesh isn't visible. If that makes sense.

[lime crest]

Performance.

[woven citrus]

Can you please send the part where you draw the circle? Also i didnt understand fully, how to you get the position of the circle? Do you raycast?

[raven pond]

Im looking for mobile friendly nature environments. Preferably realistic looking but still low poly(not style) / performant

[maiden lichen]

You use ScreenPointToWorld

Its a camera function. Now unity with in its self has a camera constantly for the editor that allows you to navigate around the scene while editing. So you can use that if you want to draw the circle in editor. But if you want it in game, you can use the Game camera.

ScreenPointToWorld is basically raycasting, but, it lets you shoot a ray from your cursor in to the world.

So you input a vec2 and it returns a vec3

That vec3 then can be used to draw the gizmo on the correct postion

[woven citrus]

But it is so expensive to do it every frame

[maiden lichen]

No not really

[woven citrus]

To raycast

[maiden lichen]

Since its in an update loop, it does it every tick

So not every frame. But lets assume that the tick rate is every 40 milliseconds. then it does it every milliseconds.

Just like anything else you have in an update function

[woven citrus]

okay, i'll try it again

btw whats the difference between drawing gizmo and using projector?

[maiden lichen]

Projector is like a decal light. As far as i know, its not really realtime in unity. So you cant really access it through scrip to alter position

But in all scenarios, gizmos are much better. They are more optimized and they get the job done at all levels

[woven citrus]

Aa, okay, now it makes sence

thanks

[maiden lichen]

No worries. im looking for my gizmo script to share it. il send it if i find it

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEditor;

public class Brush_Standard : ScriptableObject
{
    public void drawBrush(Vector3 Pos, Quaternion norm, float radius)
    {
        Handles.color = new Color(0.15f,0.15f,0.15f,0.5f);
        Handles.DrawSolidDisc(Pos, norm.eulerAngles, radius);
    }
}

[woven citrus]

I thought i need to use Gizmos class

[maiden lichen]

well it depends, this is for the editor. It works with out starting the game

But it should work in game too, try it.

    private void getMousePos(SceneView sceneview)
    {
        Ray ray = HandleUtility.GUIPointToWorldRay(Event.current.mousePosition);

        if (Physics.Raycast(ray, out hitInfo, rayDist))
        {
            objNorm = Quaternion.Euler(hitInfo.normal);
        }
    }

[woven citrus]

i'll use your code:D just for test

[maiden lichen]

XD np

But that other code is how to get the cursor to world but from with in the editor. not in game. in game it wouldnt work

you would have to use screenPointToWorld

[woven citrus]

why do you convert normal eulers to quaternion if you need eulers?)

[maiden lichen]

I need the normal of the face

[woven citrus]

I dont need to get it working in game

[maiden lichen]

To set the direction of the circle so its aligned with the face of the object

[maiden lichen]

oh, then perfect

[woven citrus]

but you can use Vector3 not Quaternion

[maiden lichen]

DrawSolidDisc required a eulerAngles value if i havent forgotten

for the direction.

If vec3 works then sure but in my case i cant remember why i used quaternion haha. it was many months ago

[woven citrus]

XD

how to put here the code?

[maiden lichen]

use `

three times

then paste the code

[woven citrus]

without cs?

[maiden lichen]

?

well you can if you want highlighting

[woven citrus]

it is usually '''cs //code'''

okay

[maiden lichen]

`x3 csharp

// code

`x3

i cant write it properly cz then it wont show

but its 3 of that weird comma

[woven citrus]

'''cs '''

arghh

[maiden lichen]

yes

[drifting crown]

It's in #854851968446365696

[maiden lichen]

but wrong comma

[woven citrus]

wdym

[maiden lichen]

Its wrong sign

correct formating

but wrong sign

`

[woven citrus]

ahh, really, i am stupid

[woven citrus]

aa, got it

if (Event.current != null)
            {
                Debug.Log("drawing");

                Ray ray = HandleUtility.GUIPointToWorldRay(Event.current.mousePosition);
                RaycastHit screenHit;
                Physics.Raycast(ray, out screenHit, 10);

                drawBrush(screenHit.point, screenHit.normal, 5);
            }

idk whats the problem with tabs

[maiden lichen]

nah its fine dont worry about it.

[woven citrus]

anyway I thought that when i mouse cursor current event isnt null

but it doesnt work when i move it

[maiden lichen]

Well if i unserstand correctly, and youre going to have it in editor. you have to use editorDelegate

Its like a seperate thread loop

[woven citrus]

what the editor delegate?

[maiden lichen]

    [InitializeOnLoadMethod]
    public void castRay(bool isTrue)
    {
        if (isTrue)
        {
            SceneView.duringSceneGui += getMousePos;
            SceneView.duringSceneGui += raycastFromCursor;
            SceneView.duringSceneGui +=  drawInstance;
        }
        else
        {
            SceneView.duringSceneGui -= getMousePos;
            SceneView.duringSceneGui -= raycastFromCursor;
            SceneView.duringSceneGui -= drawInstance;
        }
    }

[woven citrus]

aa

yeah, i know it

okay, thanks

i'll try it)

[maiden lichen]

    private void raycastFromCursor(SceneView sceneview)
    {
        try
        {
            brush01.drawBrush(hitInfo.point, objNorm, brushSizeSlider_Value);
        }
        catch (System.Exception e)
        {
            Debug.LogError(e);
            throw;
        }
    }

Now this part is the one that actually draws the brush

It calls the seperate script with the gizmo on it. and draws it in to pos

[woven citrus]

eey

it works

[maiden lichen]

there we go XD

[woven citrus]

thank you very very very much

[maiden lichen]

no worries

[woven citrus]

waait

[maiden lichen]

?

[woven citrus]

why does it work only when i rotate my editor camera?

it seems that when i just move cursor it doesnt call

[maiden lichen]

Thats when the function is being called could be why

Im assuming youre still using the mouse event

[woven citrus]

yes

[maiden lichen]

There you go

XD

[woven citrus]

when i move cursor it redraws circle in the correct position in a few seconds

but when i hold the right mouse btn and rotate camera it works

it also works when i click any buttons

[maiden lichen]

Its because of the mouse event

You need to use a different way

[woven citrus]

which one?

[maiden lichen]

Well can you try and debug the mouse pos from the rayFunction

And then check if it gets updated even when the circle isnt being drawn

If it is updating. Then its the drawbrush thats the one you need to change. you want it to be running constantly. not just on mouseEventTrigger

[woven citrus]

i have a function OnSceneGUI that is subscribed for SceneView.duringSceneGui and it actually works right

[maiden lichen]

yea just a second though

[maiden lichen]

onSceneGui would only fire on the start of the GUI. not update

When you input an event from the mouse, it redraws. Thats why OnSceneGui gets fired again

Thats why it works when youre moving

[woven citrus]

no wait it works whenever i do smth with the scene

okay, i'll debug

[maiden lichen]

Thats what i mean. youre still updating the GUI

when you change the scene it redraws

with what

[woven citrus]

aa, okay

so what is the delegate i need to use?

[maiden lichen]

The same one but different event trigger. OnSceneGui would only work on redraw and draw

So youre help is more "looking for people to work for free on my project" type of help

[woven citrus]

wdym by event trigger?

[maiden lichen]

OnSceneGui is a event type

DuringSceneGui is the correct delegate

[woven citrus]

i am currently using DuringSceneGui -_-

[maiden lichen]

?

[woven citrus]

i just named my function OnSceneGUI

but it is subscribed to DuringSceneGui

[maiden lichen]

You jack ass hahahaha. OnSceneGui is an actuall function

built in

Its like OnEnable

[woven citrus]

SceneView.duringSceneGui += OnSceneGUI;

[woven citrus]

hahaha

okaay

i am stupid

[maiden lichen]

dont worry about it.

[woven citrus]

no

i have right function

private void OnSceneGUI(SceneView sceneView)
{
SceneGUI();
}

So i subed this function to call my function that names SceneGui

[maiden lichen]

Weird. i could be wrong about this one. I remember OnSceneGui being a built in function

Like void start and void onEnable

[woven citrus]

hm

[maiden lichen]

Alright. so il get rid of that idea.

So lets think. the duringSceneGUI is what's calling that function right

[woven citrus]

yep

[maiden lichen]

But do you have a -= OnSceneGUI

That gets rid of it?

[woven citrus]

sure

it is in OnDestroy

[maiden lichen]

So can you debug when onDestroy gets called

[woven citrus]

okay

no, i have onDisable, but its quite same

waait

[maiden lichen]

Well im trying to check if onDestroy gets called randomly during scene

[woven citrus]

i just forgot to tell you that i have a window class

not editor

[maiden lichen]

? im super confused now haha

[woven citrus]

it has other functions

ohh

[maiden lichen]

Well lets not ruin anything. the script works

its just firing incorrectly. Thats what we need to debug. keep focus on that

it cant be anything else

[woven citrus]

okay

it may sound funny but it loggs correctly whenever i move cursor

but it draws when i do NOT move it

its wierd

[maiden lichen]

What hahaha

how

Like if it worked when you use the cursor then it makes sense

But when youre not moving??

well wait. could be just a stuck frame

[woven citrus]

wdym?

[maiden lichen]

You stopped inputing but it kept the last position data

[woven citrus]

it seems to be right

cause it is not a random issue

hmm

Event.current.mousePosition works fine

i logged it and everything is okay

[maiden lichen]

Alright youre on your own on this one haha. i just woke up my brain is slow haha

[woven citrus]

alright:)

it is already better than without it at all, so thanks

but i will try to make it perfect)

the function that only draws circle in the right place works fine, but it does not draw ¯_(ツ)_/¯

[maiden lichen]

Its just the trigger im sure. Just need to figure out when to call.

[woven citrus]

but it calls fine

i see it in a console, that when i move mouse it loggs

can it be a problem of Handles.DrawSolidDisc(Pos, norm, radius);?

[maiden lichen]

doubt, but not sure

[arctic elm]

hey

I have an issue with terrain vegetation. my entire terrain is 5x5 tiles or 25 tiles total

when I paint some trees on one tile, I have to add the tree in the tree list

but when I move to another tile, each tile has its own tree list and I have to readd it. is this normal? is there a way to use the same tree list for all my tiles?

[fervent hatch]

what are the commands to access and change the texture of a terrain detail (like grass) in real time, using a script?

[dusty dome]

Hello, is there any way to paint on a terrain with a custom (toon) shader ?

[fervent hatch]

just create a material with the shader, then set it to the terrain

[winter minnow]

I believe the terrain shader is a normal lit shader with the ability to use splatmaps to blend multiple textures
Unless you know how to convert the toon terrain into that system, it might not work out

[ivory mauve]

I have a map made with terrain and I want to make it a bit bigger to make a border but I don't want to stretch the stuff that is already on it how can I stretch it without stretching the terrain already on it

[mellow hatch]

Hi is there a way to get rid of this gray box at the bottom? It doesn't seem to be a game object that can be disabled. If a player goes far enough in my terrain, they will see this:

[winter minnow]

Looks like it could be a missing face of the skybox

[silver lance]

hmmm is there a way to blend a cube into a plane so that there are no hard line edges between them?

I am trying to put a dirt patch on a grass plane and want to soften the edges a bit.

[rose sentinel]

Is there any performance difference between making a 10k by 10k terrain or making 100 terrain plots of 1k by 1k each?

[woven citrus]

@maiden lichen I found the solution of my problem, so if you are interested in that: scene did not repaint when i move cursor, so i needed to add SceneView.RepaintAll(); into the draw brush function)

[maiden lichen]

XD hahaha damn

[pine mural]

Grass that doesn't kill fps. Has anyone figured this one out yet?

[scarlet temple]

I have this package called digger...but always when I want to use it my console says

MissingReferenceException: The object of type 'Terrain' has been destroyed but you are still trying to access it.

and how can I uninstall it :/

[rose sentinel]

See if it's in the package manager

Hey does anyone know any good terrain tutorials that are updated for the more recent versions of Unity? I keep trying to find one but they all are a bit outdated

[rose sentinel]

What does this error mean?

[proven shuttle]

That means whatever you're trying to access has a value of null. @rose sentinel

[ashen ridge]

How do I create terrain?

[undone lark]

Create a terrain asset and get creating.

[elfin niche]

@marble sentinel is it this one?

[marble sentinel]

nope

thats the brush pack

[elfin niche]

oh

[marble sentinel]

have you preview packages enabled?

[elfin niche]

not sure

how do i do that

[marble sentinel]

Terrain Tools is a preview package so you need to enable it

[elfin niche]

how do i enable it

[marble sentinel]

Edit -> Project Settings
Find Package Manager in the window hierarchy
Check the Enable Preview Packages box
Click I understand

do you use 2020.2 or earlier?

[elfin niche]

i enabled it

[marble sentinel]

ok

now go and get Terrain Tools

[elfin niche]

where?

[elfin niche]

installing

ah yes. it worked. thank you very much!

[marble sentinel]

no problem

happened to me a few times as well until i realized that i downloaded brushes and features and not the actual tool

[minor jetty]

Is there any way I can fix this?

[elfin niche]

@marble sentinel help. i did something. no matter what strength i choose on the brush it only raise the terrain like 0,5 tiles then stop

[marble sentinel]

what tool do you use?

and what do youu mean by "stop"

[marble sentinel]

ok

[elfin niche]

no matter how many times i press it does not raise it any more

[marble sentinel]

does it not brush at all or is it clamped at that height?

[elfin niche]

it raises it a little bit. like less than a tile

this much

[marble sentinel]

increase this

[elfin niche]

i have

no difference

[marble sentinel]

what is your terrain height?

[elfin niche]

1

[marble sentinel]

uhm

thats the max height your terrain does

so it can't goi beyond that

increase that 😂

[elfin niche]

oh really. ok. i dont know why it worked before then xD

ty again my friend

[marble sentinel]

1 is not the standard a terrain is created with so you probably fiddled around and messed it up somehow ^^

[elfin niche]

i thought it was how thick it was

so i changed it

[marble sentinel]

nope^^

see it as the bounding box of your terrain

can't go beyond that

[solemn harness]

I need some help I'm trying to design a town inside a mountain and I'm wanting the mountain to not be like a straight up wall that way the texture doesn't look stretched out but like I've tried lowering the terrain but it never does it nicely

[winter minnow]

How do you mean inside, exactly
Like closely surrounded by mountains, or carved into or under one?

[solemn harness]

So it's a mountain and it's on the side of it

@winter minnow

[winter minnow]

I'm not getting a very clear understanding from that!
Anyway, it sounds like it's mostly an artistical challenge
Cliffs are always difficult to get to look good, and if they're very sharply inclining you'll have to use meshes for it

The terrain system is based on a height map, so any sharp drops will inevitably become stretchy

[solemn harness]

Yeah I finally got that handled I just need to set opacity down and slowly lower my terrain I used a triplanar to fix it

[winter minnow]

Triplanar mapping is a good call

[solemn harness]

Haha thanks

[rose sentinel]

anyone know how to bake the shadow of terrain painted trees? that are basically sprites because of LODs. the mesh tree and cube cast shadows but the painted trees dont

[wild pewter]

Hello, does anyone know if there is a normalize function for the alphamaps? Unity is doing that when you remove a layer, but i cant find a way t oreplicate that effect by code... here is an example of a broken alphamap that gets fixed by adding and then removing a layer, so SOMETHING is going on in the background and i really need to figure out what

[upbeat solar]

no matter what i do, my heightmaps just dontwork

totally flat

im importing this

(as a png)

[upbeat solar]

nvm fixed

[winter minnow]

Do share the solutions
In case someone else faces the same issue

[upbeat solar]

i would if i knew

it literally just randomly started working

[spiral hawk]

Anyone know any reason why my terrain is not allowing me to paint any detail meshes or textures?
it lets me add them and select them but doesnt show anything at all on the terrain.

these are my settings currently... anything anyone can see causing the issue

[wary sparrow]

Hi, When painting a terrain is it possible to hide layers so they are not shown in the Scene view?

[crimson needle]

Texture layers? Or like the terrain details or trees?

[crimson needle]

Are you using HDRP or built-in render pipeline?

[wary sparrow]

@crimson needle The texture layers like rock, sand etc. The built in

[crimson needle]

I was hoping you were gonna say "terrain details" because then I could have helped 😛 Also that question about render pipeline was a reply to someone else

[wary sparrow]

I was asking as It would make it easier to see what you are painting.

[spiral hawk]

built in pipeline - on unity 2019.4

[wary sparrow]

Or what you already have painted

[spiral hawk]

it seems if i change it from "grass" to "VertexLit" in the settings for the detail mesh it paints and shows then - but even at that, it seems to only be working with various meshes (not all).

[fervent hatch]

it seems like my grass is not using dry and healthy colors

is it normal?

[rich charm]

hello people i m trying to just turn off the 4 parts of the terrain once the player collider , triggers the "ontriggerEnter" on the collider script ... but everytime ... it turns off the terrain , stops my game and this erros pop's ... what could be causing this issue?

i tryed ... run the game , and just untick it during the gameplay and nothing happens ... it just turns it off and on ...

i dunno why with the script this is happening

[mild solar]

I set 9000x20000 terrain and my brush looks oval.

How can I fix that and make it round?

[winter minnow]

You probably should make the terrain in 1:1 ratio, and if you want it long, you could use the tool that extends terrain

Don't remember what it was called

[mild solar]

Thanks.

[winter minnow]

It's "create neighbor terrains" but looks like your version doesn't have it
2017 is really old and the terrain system has gotten big improvements since

...at least doesn't have it by that name

[mild solar]

I use it since I play VRchat and it uses that 2017 version.

Guess I'll need unity hub for both latest and 2017 versions.

[delicate pivot]

hey guys, I see videos where they stack rocks one on top of each other and using mesh colliders. Is that approach fundamentally wrong in terms of performance or is there something that I'm missing?

[winter minnow]

It's always situational
Mesh colliders are expensive
Calculating mesh colliders against other mesh colliders, such as terrain, is even more expensive
Don't use them if you don't have to, but if you've got performance budget for it, there's no issue

[arctic spruce]

How can I stop my trees rendering like this on my terrain https://cdn.discordapp.com/attachments/277180794370260992/868145789745135696/unknown.png

[barren oak]

how would you like them to render?

[odd fern]

Hey, total noob here, I can't seem to use any brushes on terrain and have the message "the brush is read-only." How do I make my brushes write again? terrain collider was off

[arctic spruce]

They should look like this

[barren oak]

Doesn't look like you have any lights right now

[arctic spruce]

I have lights, in my scene they just start rendering that way after a certain distance, like there is a detail distance I need to tweak somewhere

[barren oak]

Yeah it's LOD settings

I think on the terrain?

Or maybe the tree prefab

[arctic spruce]

I have them on max here

nvm, I am an idiot

Its the bilboard start

Just had to increase that and it worked

[solemn harness]

So I'm new to unity and I'm wondering if there is a way to set certain terrain textures to automatically apply at certain heights? That way it'll look more natural instead of me painting it and over doing with certain textures

[sudden burrow]

Is this map using tile palette?

[odd fern]

also a noob, I've only used blenders node editor but the shader graph looks pretty similar so I think you can use it to do this job by plugging the position/separated Y-coordinate into a color ramp which you use to mix your image textures.

[odd fern]

anyone have tips/tricks for making this view look more photorealistic?

[dawn spruce]

Grass looks awful

Have no suggestions though

[odd fern]

it does look pretty bad up close but this is more of a background and you won't be able to walk up to/through it as a player

[dawn spruce]

aha

[odd fern]

I'd say about 10 gridspaces away at a minimum

[dawn spruce]

Graphics aren't really my thing, I'm only recently experimenting with Post Processing and basic terrain sculpting, it's embarrassing

[odd fern]

I have experience in blender and roblox so i figured it was time for me to finally use unity and do something "real"

[dawn spruce]

But I got the bit where you shit on Unity's grass, so that should explain my reply 😄

[dawn spruce]

As long as "real" means fun, then good luck!

[odd fern]

also do you know how I can put grass on non-terrain meshes?

[dawn spruce]

grass is just prefabs you can spawn with the terrain tools or manually

even if your grass is a texture2D (i think)

[odd fern]

can i use a brush for it?

[dawn spruce]

never tried to put grass on non-terrain meshes

i usually google things i'm trying to learn, actually, that's the only way to learn 😆

Man.. imagine if we didn't have google

Oh god... we'd be on Bing!

[odd fern]

hey man don't diss bing it has

occasional useful purposes

[viral schooner]

I hate importing from Blender to Unity... this was supposed to be a forest terrain

[minor bluff]

Hmmmmm

DISASTER

looks like there was an avalanch and a fllod at the same time

[viral schooner]

it's a nightmare lol

[desert sun]

really? maybe you forgot some checkbox while exporting a FBX?

[barren oak]

What did it look like in Blender?

[viral schooner]

it looked like a forest lol

[viral schooner]

i exported as fbx

but i think since blender to unity has some weird -90 rotation bug maybe all my trees just splattered

[barren oak]

It's not really a bug so much as the two programs use different coordinate systems

and you have to account for that in the export

but your trees don't look rotated, they look.. flattened 🤔

[viral schooner]

yeah

i don't know much about it but I ended up using Unity terrain

[ivory mauve]

I'm trying to place a rock using terrain but it's not coming in the scene and no error is coming

[wraith shadow]

Am I missing something here? Is there more to Unity's terrain system?

At this point Unity's terrain is out of the question. Blender is just so much more feature complete than this

[winter minnow]

What are you looking for?

Blender gives you more power if you know how to use it, as in most situations

Terrain's advantage is that it comes ready with chunks, LODs and instancing

But on the forums some say that coding your own version of those for mesh renderers would be faster, but then it's on you to make the texture painting and layering shaders too

And grass and trees

[left jackal]

Yes, download Terrain Tools from Unity Package Manager

Cheers

[upbeat solar]

my trees disappear when their bases go out of view

fix: https://forum.unity.com/threads/case-1227083-tree-nature-soft-occlusion-shader-in-urp.825825/#post-6220065

[wraith shadow]

I've taken to using ProBuilder to block it out, then importing to Blender to create the final product. I still haven't gotten to the exporting phase, but so far ProBuilder is great

[left briar]

Why does my blender object makes my project laggy?

[winter minnow]

What kind of object is it

How many verts does it have

[left briar]

Is that important?

[left briar]

A plane

[winter minnow]

You're not giving much info to help track down the issue

If it's a mesh with millions of verts it might not be a mystery why it seems laggy

[left briar]

Yeah, that could be the problem

[pine crystal]

How do I add a material to terrain?

[trim fern]

Go to texture paint option

And add new layer

Rest is self explanatory

[lime relic]

Humm... is it a feature or a bug when the terrain is not occlusion culling properly? I'm really suspecting that the game is rendering everything behind a hill due to a poor performance.

[winter minnow]

RenderDoc is useful for verifying things like this

I think occlusion culling only happens with baked occluders but I'm not entirely sure

[ornate yarrow]

tips for 2d level designing?

[winter minnow]

That depends a whole lot on the type of game

[ornate yarrow]

I want to create a simple game, just cubes

[winter minnow]

Platformer? Top-down?

[ornate yarrow]

Platformer

I tried to create a sky for it and turned out pretty weird 😹

I want to create a simple Swordigo like game, but cubes

[winter minnow]

Something to always keep in mind with platformer level design is to base all level geometry around the player's movement abilities

Build a sort of "palette" of heights and chasms that the player can scale with relative ease
Most jumps shouldn't be ambiguous about whether they can be reached or not

It feels awkward if some walls are just barely too tall to be reached, or if some steps are just barely too tall to be walked over

[ornate yarrow]

I see

[lime relic]

Your tip was the solution. Just found the rendering > occlusion culling pane. Baked and it's working now. Thanks!

[trim fern]

Is there any way to make terrain “details” with HDRP

[coral anchor]

Hi there! I'm reading a lot about using terrain to create the cliffs and mountains and didn't find the "best way" to make it, because i think I won't be able to create nice cliffs only using unity's terrain. Did you end up using the mixed approach (terrain + cliffs objects - like the digger asset says) or found a way to use only the terrain? Cheers!! 🙂

[coral anchor]

So... 3D Game Kit uses only meshes for the whole environment, without Unity's terrain, would that be a "best way" to create big scenes? (The asset has 2 scenes, but they aren't that big comparing with "open world-ish" scenarios...)

[winter minnow]

Unity's terrain is entirely height based so a mixed approach of using separate meshes for steep cliffs might be the best compromise

[winter minnow]

How much optimization you need depends on your target platform and hardware
I don't know what optimization techniques the 3D game kit uses but you're probably going to need something extra if you're doing open world scale things
Unity's terrain already has instancing, tiling of some sort, LODs and all the same for foliage, but I believe it doesn't have chunk loading/unloading which you would have to implement yourself

[coral anchor]

What if I have a "city/some area" at the top of the cliff? Add another terrain or use the same? Or even if I have some steps at the cliff

[coral anchor]

Yeah, I has reading that the good part of unity terrains is the built-in LOD

[winter minnow]

Both are options
If the terrain above isn't overlapping the terrain below heightwise, then they could be connected, with the difference cut out with "paint holes" tool
Terrain can also be extended in any direction using the "create neighbor terrains" tool

[coral anchor]

Imagining that I have some scenario like these, how you'd you better build it? I mean, what part would be unity terrain and what part would be meshes? (Just created a random scenario @ blender, i think its easier to show an image than write what I'm trying to build)

green = walkable
gray = not walkable
blue = water ou roads

I'm struggling to think what would be the best approach

only the base (blue) as a terrain and everything else as meshes? Or the walkable area (green) as terrain with surrounded meshes? Or smth else?

and imagine that I might have some big mountains (with walkable places at the top)

[coral anchor]

maybe this one can show more higher places so its easier to actually see what I mean

[hot lark]

Does anyone know where I could perhaps find a tutorial to make my terrain do like this blend thing

[sinful wren]

Heyo, can someone here help me guiding me to the right direction to bake light with multiple terrains?

I tried googe for 3-4 hours with no success sadly, when I try to bake them all at once: unity crashes

when I deactivate all terrains and bake one, it works

but when I do it with another one, the first lightmap gets replaced

[winter minnow]

I guess it comes down to size and whether you want to use the Terrain's foliage system or supplement your own

I can't tell what's the size of those cliffs, but if they aren't totally huge, then they can be frustum culled as separate objects, unlike one big continuous ground

[ivory mauve]

Going to make flowers but don't know how to make them for the terrain can anyone suggest

[ivory mauve]

found how

[coral anchor]

Didn't know about Frustum Culling, really nice stuff!

[coral anchor]

Yes, its ok for me to place trees and stuff by my own on those places, I was thinking more from the performance perspective (if it would be a big hit to use mesh for those places)

Thanks Patchi, really appreciate all the help!

[winter minnow]

Not a big hit probably, but if you use your own meshes, make sure they have LODs

[coral anchor]

sure, I think LOD is a "must need" after this whole week reading about it 😂

[rose sentinel]

I have a question regarding terrain, if working on a big open world for rpg game, would you create 1 big terrain for entire world or create many "chunks" of terrain and load only those that are nearby?

[low pecan]

you need to chunk it for a variety of reasons 🙂

open world is super technical

not builtin to unity

[rose sentinel]

should I start with chunks of terrain or one big one and then cut it somehow?

[low pecan]

go with the chunks, they sort of help you by auto lining up new terrains

then you need to export individual pieces to either scenes or prefabs and stream them in when required

like i said its pretty heavy work because its not builtin

you will want to write your own editor tools to accomplish a lot of grunt work

[rose sentinel]

how big a single chunk should be? I guess it depends on a lot of factors but just wondering

[low pecan]

the unity floating point math breaks the physics past 10000 in any direction

so you need to correct for that too by moving everything

its a pain

the normal terrain size is fine i think for a chunk

keep in mind you need to load 6 chunks at a time

to cover all views

around the current chunk

[rose sentinel]

wait what? woah that's a useful piece of information

[low pecan]

yeah its actually not just unity

its just floating point numbers break in accuracy

past that

https://forum.unity.com/threads/floating-point-errors-and-large-scale-worlds.526807/

5000 even allegedly

[storm falcon]

hi guys me and my friend are working on a survival game, hes highly experienced in these kind of things but diffrent time zones, so i wanted to ask, im made a procedural landmass generation but its mostly mountains now i want to mix this with flat land like a normal survival game, but the problem is where do i start.....

[marble sentinel]

i never tried to make a procedural landmass but from my logical perspective i'd start with figuring out where in the height map the large chunks of similar height values are and then find the average and set the average to smooth this points

that way you get your first plateaus

the edges of said chunks should be altered less strong to get a better fading

how you do it? no idea. am not a programmer. just started brainstorming

[lime relic]

I'm having problems with terrain texture's smoothing. The ground looks like it's under a plastic wrapper if the smoothing is enabled. Disabling fixes the issue but here's the thing: the setting always resets when I reboot the editor.

Is this a bug or am I missing something?

Here's the setting I mean.

Terrain without smoothing.

[marble sentinel]

the "Plastic" look is intended

The Smoothness is set in the Mask Map, and since you don't have a Mask Map unity needs to come up with a value (which is 1 by default)

which doesn't make it look like plastic but it makes it shiny and smooth which is kinda plastic

but i can't tell you why it resets the channel default value if you reboot. i don't think that is intended

[lime relic]

I see, that explains a lot. Thank you.

[lime relic]

Agh... it doesn't save mask maps either.

I've created the terrain with World Creator 2 + Bridge Tool. I wonder if Unity is somehow locked into those exported terrain values. Really bizzarre.

[lime relic]

Is this caused by metallic channel (R) in mask? For some reason it won't go away no matter what. The lack of URP documentation about the file formats and what not is puzzling.

[lime relic]

Freaking solved. I had to manually create a new terrain, duplicate the world creator bridge created files and modify those instead. What a great exporting tool...

[ivory mauve]

does anyone know how to stop leaves to light up all at once

when a light goes on the tree

[hazy shard]

Don't crosspost

[ivory mauve]

no found it was lighting issue

[hazy shard]

yeah

[river steeple]

Hey, I put trees on my terrain, however they are 1 single gameObject, when printing .name, it all returns Terrain. I don't like this since I would like to cut trees/interact with them. Is there any workaround?

[rose sentinel]

yes im here

my terrain brush is not working can anyone help me?

[glad pine]

Hey there NeXto, do you mind explaining what you mean my "not working"

[earnest briar]

My grass is being culled in chunks, but I want it to gradually fade away. Does anyone know how to do this?

[wooden zenith]

Hello. I'm in need of some help. So some context, i downloaded a package that essentialy help's me create roads on my map however i want it to be, however that requires that my terrain has unity's terrain system for it to work on. However i have allready created a terrain outside of unity (in blender) and i'm wondering is there a way to trick unity into using my allready made terrain to work with unity terrain?

[winter minnow]

There's a paid asset and a free script floating around that claim to do that which you can find pretty easily
If they're not an option, you could always convert your mesh terrain into a height map and import that height map into an unity terrain

[wooden zenith]

What the script/asset called so i can search it up?

[winter minnow]

Object2Terrain
I can't make any guarantees about its functionality

[wooden zenith]

@winter minnow found it. The strange part is im looking at a tutorial on how to use it and the guy just clicked on the script in the editor and a new tab apeared in the top, i however when i double click it opens visual studio and now clue how to execute it

[scarlet temple]

does anyone know how I can select only 1 terrain with my brush. I wanna make a hole on one terrain but I always accidently paint on the other terrain as well

[quiet owl]

Hi, I am currently looking for the terrain tools, but I caNt find it ... is it moved in the 2021 unity version I use?

[ivory mauve]

why is my flower looking like this when I made it I gave it no background

[winter minnow]

You checked "alpha is transparency" in import settings?

[ivory mauve]

fixed on it's own

[verbal lichen]

Hey guys im making a VR Game and im wondering if using the Terrain Tools will be optimized enough to run on the Oculus Quest 2?

its a mobile standalone headset it runs an XR2 chip

[rose sentinel]

Hello sorry for delay my problem got fixed as I realized that my terrain brush was set to paint texture not raise or lower terrain

😂

[scarlet temple]

hey, I just commited my changes to github... also using LFS.
now I work on a remote computer and loaded the github changes. but all my terrain dissapeared and the assets look like this.
idk why

[rose sentinel]

how can I make the border between terrain layers sharp in the new terrain system, rather than blending between layers?

I'm trying to do something like this

[scarlet temple]

how can I make a unity terrain or lets better say multiply times which are REALLY deep like 10k meters deep but still have the possibility for details on it with my brush... is it even possible?

[winter minnow]

If you mean details on the slope, then not really
The terrain is heightmap based, which means steep slopes and walls will have no surface information resolution

[scarlet temple]

yea... I fight with myself for the last...lfew weeks with that.
I want to make a subnautica like game and for that, you will be able to dive REALLY deep into the water.
the problem there is, that I also want some small hills but the whole map will still be like 10k deep, so this makes it pretty impossible to use my brush for small things as well

and idk how to even begin with that. I tried to overlap a small terrain on a big terrain... (does this make sense?)

and thanks for your answer patchi

[winter minnow]

It requires a more advanced type of terrain generator, probably something that stores the information in some sort of 3D array, probably
Or mesh terrain made with a modeling software

[scarlet temple]

hmm tysm already. you're really nice 🙂

[winter minnow]

There are some solutions on the asset store for terrain like that, but they're not free
That kind of terrain system is much more complex to implement

[scarlet temple]

I do have the terrain toolbox but this thing doesnt really allow me to do much more stuff...

[scarlet temple]

thats true...I also payed for Digger...but this one is made for small stuff

[winter minnow]

Ah, Digger is exactly one of those systems

Does that work for you?

[scarlet temple]

but the brush size is really small so... well idk
it does work yes, but only for small cliffs for example

I feel bad for writing so much and asking these questions ^^
why are you here btw? are you also working on something in unity?

[winter minnow]

Making complex terrain in a modeling software is pretty easy, but the hard part is optimizing it for large scales

[scarlet temple]

I mean, as you can see...I am not advanced with unity yet 😄 but I do give my best to learn stuff and also help other ppl later

[scarlet temple]

hmmm sooo you mean in blender or pro builder? (things I am bad at xd)

[winter minnow]

Sure
Advicing others forces me to look up things and test them so it's a decent way to learn

[winter minnow]

Blender, Maya or Max or such

Ah, Digger's authors offer another package for big voxel based terrains
Similarly pricey

[scarlet temple]

ahh okey I will look up for it 😄

I mean...ugh its pretty complicated... I want to draw small things which are not polygon AND not 500m high on my map with the brush,
but I also want my map to have cliffs that go a few tousand meter down...its not easy ^^. but maybe these tools you said will help me

[scarlet temple]

I'm dying inside bcs of this shit right now...

[winter minnow]

<@&502884371011731486>

thanks ^^

[scarlet temple]

lol..this was fast

it was propably a rick roll or scam anyways

[reef marten]

hi all. is there a way to use the terrain details system for grass textures in unity 2019.4? thanks!

[candid vapor]

does anyone know where terrain layers are found i cant find them anymore 😄

[reef marten]

go to your terrain, paint. scroll down

[undone lark]

In the future, don't spam your questions across multiple channels.

[candid vapor]

yeah i did it but its not there anymore

[candid vapor]

oh okay sorry

[candid vapor]

i cant see my terrain layers anymore

[earnest briar]

My grass is being culled in chunks, but I want it to gradually fade away. Does anyone know how to do this?

[elder tapir]

hey if you start creating your world design / terrain do you know already how it should look or you just randomly start and work till you think that's cool

[winter minnow]

Feels to me that improvising rarely works with terrain
Real terrain's shape and texture are formed by very particular natural processes, and influenced by deliberate human design
It's very difficult to create something that seems believable at least without reference

Even for placeholder terrain it's often better to use blocks and ramps to represent terrain

[vast warren]

Hey, I am trying to make an area for my game, but it always feels like its just a square floating in space. I dont really know how to make it feel like a vast land while keeping my player confined. Does anybody know a way to do this?

[winter minnow]

oftentimes there's extra terrain outside of the accessible terrain, which can be low res as the player won't get close to it

And beyond that a 2D image of an even more distant terrain, like a cardboard cutout, or one such embedded into the skybox image

[verbal lichen]

in my opinion this one is a bit harder to achieve because if you can tell that part of the terrain is not physical the immersion for the player might go down especially in a VR Game

[winter minnow]

Good point! Though very far away objects have practically no parallax, and resolution limit jumbles things up, it's still worth avoiding flat environments
It depends a lot on the type of game
Sometimes all you need is to give the idea of a world that continues beyond the stage, even if it's obviously fake

[verbal lichen]

its defo a think to play around with

[winter minnow]

I remember in old racing games the borders of the level very clear and the world out there very blocky, but it got my imagination going

[verbal lichen]

takes a bit of time to get perfect

[verbal lichen]

Haha yeah, Thinking about if Fog is good too

like adding a bunch of fog far away makes it look like the world is kinda fading out but it might still feel like it goes on

[winter minnow]

Even color gradient skyboxes can go a long way to painting a mood and an idea of a scene

[ripe vigil]

Not exactly a terrain thing, but does anyone have any advice for making damaged post-apocalyptic roads for an open world game?

[rose sentinel]

Hello, i've found a grass shader tutorial minionsArt, question is it better performance wise than terrain tool with prefab grass?

[toxic quest]

my set height setting isnt working. can some one help?

[jovial pier]

Could anyone throw some ideas at me for this?:

My project requires a small area of deformable terrain (at runtime). At the moment I'm using the built-in terrain, 32*32 with a heightmap resolution of 1024*1024. While it functions well enough (digging and filling small holes), sadly it looks kinda bad...

I can up the resolution, but it doesn't seem to be worth the slight visual improvement, this also causes a small but noticeable stutter while deforming it.

What can I do? Looking around the asset store there doesn't seem to be anything aimed at small terrains, and without direction I'm not sure if I can come up with anything by myself

[verbal lichen]

you should probably smooth that terrain

unless its supposed to be blocky like that

[winter minnow]

Looks like there's no falloff/AA of any sort with your terrain brush
Fixing that would get rid of the blockiness
It'd also greatly benefit from a shader that changes the texture or color based on height or surface normal

[jovial pier]

Ah....for some reason I didn't see how it looked with the actual terrain tools, went straight for the code :/

Yea it's perfectly fine, just need to write some better code for the runtime tools. I also have a something that adds dirt around the edge when it's below a certain height, but it was disabled. Doesn't look half bad when the real textures are added. I'll look into making a shader though, probably could look better

Thank you @verbal lichen @winter minnow

Smooth 🙂

[left briar]

Why cant I texture paint with the universal render Pipeline?

[scarlet temple]

you can

you just need to use another material

from the pipeline

okey...so I made a commit in github again and I had 2 groups of terrains in my assets.

group 0 & group 1.

as you can see, the terrain tiles group 1. is weirdly not there on my 2nd/remote computer and idk why because the other terrains are there 🤔

[left briar]

Oh, I found the error, I only had to make the texturequality normal and not to half

[scarlet temple]

ahh okey

[low pecan]

anyone done some open world stuff ?

[scarlet temple]

I plan to ^^

[low pecan]

im concerned about the floating point accuracy problem

[scarlet temple]

why? I don't have any experience soo yea idk

[low pecan]

genshin impact was made in unity and has a nice open world

but i really want to know how they handled that

and the streaming

i am probably going to go with async loading in scenes in a grid like manner

based on player position

[scarlet temple]

wait..genshin impact was made inUNITY??? 😮

[low pecan]

sure was 😄

[left briar]

But now it says that “the current rp Does not support detail shading“

[rose sentinel]

me me me, still on very early development though.

[low pecan]

how you going

[rose sentinel]

not very good, i've just started learning.

[low pecan]

yeah its not an easy thing to do

and you have to take into account unity degrading past the 5000 x/y/z

[rose sentinel]

eh? i didn't even know that one hahaha

[low pecan]

yeah if you go too far everthing starts getting less accurate and twitchinbg

[rose sentinel]

i see, mine might not that big, i haven't encountered that issue yet.

[winter minnow]

The most common solution is to move the world around the player, instead of moving the player within the world, either constantly or periodically

[left briar]

Why is this happening?

And how to download the terrain tool in the package manager

Because I can’t see it there

[reef marten]

hi all. is there a way to use the terrain details system for grass textures in unity 2019.4? thanks!

[low pecan]

Hmm 🤔

[ornate elk]

hey, it wont let me use the paint texture tool for my terrain. anyone now how to fix it?

[trim fern]

Hey im working with HDRP but i cant use detail shaders is there a fix to this or i will have to use 3D meshes

[wanton hound]

Hey guys i need some help that i couldnt find very fast atleast

if i have a terrain and i put 50 terrain layers on top of each other but only the one on top is visible, does it affects performance ? or unity will think there is only one layer there

[trim fern]

only one layer i think

but why would you put 50 layers on top of each other anyways

[velvet oar]

does annyone know this what this texture asset is caled

[pulsar socket]

is there anyway to create and modify superlarge terrain without lagging out my gtx 1650 or ryzen 5 4600H or do i simply need a better pc for large terrain

nvm

[verbal lichen]

you shouldnt ever need a better pc to run something, instead you need to optimize it so people with a PC like yours can run it

if your PC cant run your game then something your probably doing something wrong

[pulsar socket]

yep... did a bit of searching and found many other ways to do this

[winter minnow]

It's nice to share your solutions when you find them
Helps others

[pulsar socket]

i found a lot of solutions on google an now im using l3dt to make terrain

also said many and not that i found a specific one

also i may use something different because as of now i cant genarate good looking terrain

[cosmic oar]

Hey ya'll, i am fairly new to Unity/blender and i wish to start with some low-poly terrain creating. Do anyone of you have any tips as to where i should start? I see examples such as polybrush etc, should i use those?

[worthy wind]

i have made a tree in unity using probuilder, but because it is using pro builder's mesh filter it gives me an error that the mesh renderer is missing, any way to use pro builder trees in unity terrain?

[tawdry remnant]

I'm kinda in the same boat. I was using Unity itself to make a terrain I was happy with this, but then I had to make the NPC/character models and found I needed to use blender for that...however, I'm not the best artist...so they came out looking very low-poly-like characters so I thought it best I change the terrain stuff to low poly too....however I have a problem.... the coloring in Blender's screen looks normal. After exporting and loading into Unity, the colors are totally different or non-existent entirely...

Blender

unity

[worthy wind]

if its terrain try changing terrain setting

the material to

built in legacy diffuse

i had incorrect colors too and it fixed it

[tawdry remnant]

well, when I import the terrain into unity, it just has a Mesh attached to gameobject

am I meant to add a terrain component + terrain collider?

is that what you mean by changin the terrain settings? I'm not sure of any other settings to be honest

[worthy wind]

maybe something in the mesh renderer material

[tawdry remnant]

in unity right?

[worthy wind]

i wasn't able to export something into mesh from blender before

[tawdry remnant]

not blender?

[worthy wind]

yeah since in terrain its material that does that maybe in mesh renderer it does the same?

haven't tried though

[tawdry remnant]

ill see

what would you suggest changing? 😮

[worthy wind]

try changing smoothness

[tawdry remnant]

okay

seems to make it shiny/reflective of the sky the more increase it but sadly doesn't alter the colors 😦

but I do like it with more shinyness XD

but still neeed to figure out the color issue

😦

[worthy wind]

maybe changing the albedo color to more black makes it darker?

[tawdry remnant]

okay ill try thx

hmm, it increases darkness of all the existing colors

but that missing one doesnt appear

is it possible that Unity just cannot understand Blender's imported color? so it just changes it to "yellow" for all shades of yellow?

[worthy wind]

im guessing it might be unity light is different than blender?

[tawdry remnant]

this is possible

[worthy wind]

try lowering the scene light intensity or highening it

if it doesn't work then it might have something to do with blender

[tawdry remnant]

yeah its not helping 😦 I guess its something on blender's side

there is another issue with this too

when I'm in modeling or UV Editing modes , the terrain looks like this:

you can clearly see the path outlines

but you see from my earlier pictures...when in shading/rendering or exporting to unity..it becomes very different

in some areas completely gone

know any reason for that by any chance?

[worthy wind]

i don't really know much about blender but im guessing the shading or rendering gives it better light or something

[tawdry remnant]

yeah its weird, it almsot deletes 50% of the path

thank you for trying though

I might end up havign to go back to normal terrain in Unity =\

[worthy wind]

im trying to paint trees in terrain (they are models made out of cubes, not unity tree) but when i do that they are way too small, strange thing though is when they are billboards they are the size they are supposed to be, any fix?

[worthy wind]

fixed it, highered the billboard distance and using pro builder i merged the 3x size tree with an empty gameobject so the games thinks its size is 1

[wide pier]

i dont know if this is the right place to discuss but im having some issues with Probuilder.

i know its not terrain but it seems to be the most-related. Let me know if i should go to another channel

[tawdry remnant]

how can I get more sharper colors? so it's less "blending" "smoothed"?

[winter minnow]

Your blender scene is being lit by HDRi environment in filmic color space
It's bound to look different unless you can get that in unity

[tawdry remnant]

sorry I'm new to this. I'm not sure I follow you entirely

[open cargo]

guys why does it say this

[tawdry remnant]

looking quickly I'm using standard rendering pipeline which is not HDR unless I'm mistaken?

[winter minnow]

It looks different because the lighting in the blender scene is different
Also the material's smoothness is different but you figured that out already

[tawdry remnant]

I'm not using blender at all here, this is purely Unity and unity's terrain tools

[winter minnow]

Wasn't the issue that the terrain in unity looks different than it looked in blender

[tawdry remnant]

oh, no that was another issue I had with another project. I decided to scrap that for now and started a new solely in Unity project for now and so far all is well , except the colors look a bit washed out/overly smoothed like in the above picture. I would like (if possible) for the grass/green texture to come to a complete stop at the "edge" and then the gray texture to start "fully" from that edge onwards if that makes sense

instead unity seems to be trying to "blend" and smoothly transition between the two colors which makes it blurry/fuzzy :S

[winter minnow]

Ah, I wasn't talking about that

[ornate elk]

i asked this a few days ago and didnt get an answer. it wont let me use the paint texture tool for my terrain. anyone now how to fix it?

i tryed to change the layout but it didnt fix it

[tawdry remnant]

oh i seee XD

guess i can live with it but yeah bit annoying really 😦

[worthy wind]

sorry if this is late but i had some issues with probuilder and terrain today too what is the problem

[wide pier]

I tried to change a face to a different material and all of them get set.

so even if I have like 4 materials on a probuilder mesh. it just ends up being 1 material.

[winter minnow]

My understanding is that they have to be blended, as a vertex can only hold one color, so the area between vertices is an average of those values
Found some forum posts saying it's possible to have multiple colors per vertex so they're separated per-face, but I think they're wrong

Well, it can be done but it requires vertices to be duplicated, as with sharp normals
I'm like 85% sure terrain doesn't support sharp/duplicated vertices

[floral crow]

Sounds like you might have selected the whole object instead of just the face you wanted

Make sure you are using polygon selection mode (if im not mistaken 2nd from right on the buttons on top of the viewport when the probuilder window is on)

[wide pier]

that's what I did. only a face or two is highlighted

the way I've fixed it is to restart unity

[frigid ledge]

can anyone help me assign this layer to the terrain?

it is pink at the moment

what

oh the brush?

like this?

then what

but at least you know its pink bcs there is no material assigned to it right?

yes i tried but it didnt work

anyone else?

knows why

what how

nope

[floral crow]

huh. that IS odd

sounds like a probuilder bug, i havent had it happen to me personally though

[tawdry remnant]

thanks, how might one go about doing that? is that something that can only be done in blender?

[winter minnow]

I didn't test it yet, but apparently if you hide a face and vertex paint on an adjacent face, the hidden face retains its color and there will be a sharp color edge between them

Imported meshes support split vertices, so I guess it would work

[scarlet temple]

what is a good height resolution on terrains for more detail with brushes? because mine is on 300 and its way too sensitive/high

[jaunty hollow]

my terrain ground check does not want to work, it checks the Layer "ground" to see if its colliding. it worked but then i changed to a terrain now it does not work.

idk what to do to fix

[undone sundial]

how do i go about getting the grass texture in the middle looking a little less flat/one dimensional? i tried painting actual grass onto it but that sort of gets in the way of the battle when the round starts. do i just use some other grass textures and try to blend them?

[toxic schooner]

That’ll work. There are assets for it, but just more texture variations is the vanilla unity way

[undone sundial]

Are there any assets you recommend that are good for beginners? Everything I paint comes out pretty ugly

[shy scaffold]

Terrain related Question:
Is it possible to rename A heightmap file using Gimp 2 and if possible, How❓

[swift kernel]

do you know what to rename the said file to make it work in unity

[shy scaffold]

Yes it's eather .Raw or .RAW

[swift kernel]

so you only require the information on how to rename the map file or get it from google to desk right

[shy scaffold]

Pretty much Yeah

[swift kernel]

hmmmmm

[shy scaffold]

So if someone knows let me know by a ping

[spiral garden]

What exactly are you trying to do?

[shy scaffold]

Copying a heightmap from google and renaming the file throw gimp but i'm a rookie with the software

[spiral garden]

Why do you need Gimp to rename the file?

[swift kernel]

what i understand is that using a heightmap requires a file rename to .raw so it can be used in unity right

[shy scaffold]

Yes

[swift kernel]

https://youtu.be/MWQv2Bagwgk

[shy scaffold]

Thats what i been rewatching

[swift kernel]

so you require a photoshop to get this right right

[spiral garden]

Who said that?

[swift kernel]

allo said earlier

[spiral garden]

I see. Weird, but ok

In Gimp you can export the image as raw image data:@shy scaffold

[shy scaffold]

Thanks 👍

[shy scaffold]

Btw do i just copy the heightmap or save it with a name, and would this work on both gimp 1 and 2

[spiral garden]

Copy from where to where? And I'm not sure about gimp 1, but why not get the updated version? It's free anyway.

[shy scaffold]

Im using the 2nd so just checked and for Copying from google to get the specific land scape

[spiral garden]

You'll need to open the file in Gimp of course. Then just export it as raw. No extra steps needed.

[shy scaffold]

I think i understand thank you for the help

[scarlet temple]

hey... I again run into the problem, that when i work together with other ppl on github on the map, the terrain is actually missing on the remote computer and I have no idea why :/

Don't get confused, there is a terrain under the missing one and this one is weirdly there :/

[elder moth]

Hello i want to cut terrain forward line but I don't find any asset.

[pale echo]

Don't judge its my first terrain

[rustic hearth]

is it really your first terrain?

[pale echo]

yes, in unity anyway. I used to work in a smaller developing program

as a low poly builder

but this is my first high poly unity terrain build

did watch some tutorials

[rustic hearth]

great work!! @pale echo

[pale echo]

Thank you that’s really motivating to hear!

[languid crane]

Looks nostalgic…

[languid crane]

Looks amazing! You def have potential!

[pale echo]

Thank you!

[pale echo]

made another one

[gilded crown]

can anybody help me understand how to remove a specific terrain layer during runtime in a script?

[winter minnow]

What's best I cannot say, but Ultimate Terrains looks capable
Does destructible voxel type terrain among other things

[obtuse monolith]

so i have a problem with my map .. as you can see i made an box collider for my grid which contains my tilset but my player keeps falling even though i gave him a rigibody2d and a box collider 2D

[shell jolt]

Any way to handle laggy terrain editor while in editor mode?

The lag driving me nuts tbh

[winter minnow]

One possible cause is that if auto generate lighting is on, it might try to regenerate the lighting every time you make any change to the terrain
Otherwise try reducing the heightmap and control texture resolutions, I guess

[shell jolt]

how can I stop it from regenerating lights in realtime?

[winter minnow]

Lighting window has this checkbox

confirm that it's off

[shell jolt]

Thats in terrain editor or my hdrp light? This is my first time using Terrain Editor 😃 ...

[winter minnow]

Lighting window is a separate window that exists in all rendering pipelines

[shell jolt]

ah ok 👍 I got this thanks @winter minnow

[shell jolt]

Pretty sure in non hdrp the default is off, why it's turned on in hdrp I've no idea. And yes it works!

Are there any free alternatives to Nature Renderer to scatter grass on the Terrain in hdrp?

I noticed when I used the Tree tool to scatter the grass, the drawcalls were doubled

[spiral garden]

If you're using realtime shadows any renderer that casts shadows doubles draw calls.

[modern forge]

https://i.gyazo.com/d91673dfebe62b9905df310a55877f77.mp4 can anyone give me feedback/advice for the grass?

(ignore the terrible trees and walk anim lol)

[swift kernel]

@shy scaffold were you able to do the heightmap

[shy scaffold]

Well i found the high quality one i pressed save as changed the name but it ain't showing on gimp at the open file so i can edit the said file to raw

[swift kernel]

okay try dragging it into a folder at the my computer than open gimp and pick the folder where the map is located than you can figure out how to edit

[shy scaffold]

Thanks it worked

[swift kernel]

now look the hint you got earlier and use that

[shy scaffold]

👍

[torn latch]

how can I get this to fill back in?

[torn latch]

the grass looks as big as the flowers, maybe reduce each one to a blade of grass or some longer plant like wheat-length grass and I personally think it'd look better but overall it looks good regardless

[modern forge]

thank you!

[torn latch]

ofc, it looks good! Keep going 🙂

[torn latch]

okay so set-height makes holes in my terrain

[modern forge]

Does TreeInstance.Position refer to the terrain position of the tree or the world position?

[winter minnow]

Sounds like that would be fairly simple to test

[modern forge]

According to my tests, the tree will always display position (0,0,0) which doesn't make much sense

[shell jolt]

Tested compute shader for grass and mind blown by how lightweight it is, yeah, this is much more preferable than the default grass feature in Terrain editor which such a performance killer

[torn latch]

uh

can anyone tell me why my terrain has holes I can't repair in it?

[tawdry remnant]

just wanted to say, very well done. this is great work

[rose sentinel]

Why does Raise and Lower terrain break, it stays on one piece of terrain and I have no idea how to fix it
It's actually stuck in palce

place

[rose sentinel]

probably increase the textures res

try that

and see

All of my tools get stuck in place

why does this keep happening

[spiral garden]

Wdym by "stays on one piece"?

[rose sentinel]

place*

[spiral garden]

Mind demonstrating with a video/screenshot?

[rose sentinel]

I can't ss on this computer, it will probably explode

So basically what is happening, after I use a brush for a certain amount of time, it just the freezes, I can't use the brush anymore

[spiral garden]

Perhaps you reach the upper/lower bound of the terrain height.

[terse flume]

what is a good terrain/to player height?

[vast warren]

Does anybody know how to convert 3d models into tree prefabs to use with terrain tools?

[modern forge]

Yeah

Step one is to put the tree 3d model in your game. You have to add an LOD group* That's probably what you're missing

When that's done you make a prefab with your LOD tree and add it to the terrain tree prefabs

[rose sentinel]

Wdym

[vast warren]

Ahh I see

[vast warren]

Yep

Worked perfectly

Thank you for the help

[vale gulch]

anyone know how I could get a height map from google earth?

I found a site for SRTM that ended up generating 3 files ,how i can turn them into a height map?

[winter minnow]

Terrain uses .raw files for height, right?
If so I think you can open the .tif in gimp and export it as raw

[vale gulch]

the .tif map ended up being only 2 colors , its not a height map

actually nvm , found a better way , thanks anyways

[lusty pumice]

Are there any Unity devs on here? I have tried posting about a certain issue on the forums but it never gets any response, so I guess I'll try here. Maybe I need to post a bug report for it to get eyes on it.

There is a major issue with how Terrain Auto Connection works (for terrain neighbors). Every time a terrain is enabled or disabled in the scene while the game is running, an internal AutoConnect method is automatically called. The first thing this method does is clear the neighbors of EVERY active terrain in the scene, regardless of whether those terrains actually are using the Auto Connect option in the inspector.

In my situation, I do not use Auto Connect, because it is slow and produces unecessary garbage. Instead, I manually connect the neighbors of terrains over multiple frames using the SetNeighbors method. This works great because usually it's terrain in the distance that are being loaded in, and the player will not be able to see seams that appear for only a second.

However, because the internal Auto Connect method is called automatically, and because it clears all neighbors no matter what, I am left with terrain closer to the player which have not had their neighbors changed, yet still need to have their neighbors reset. Seams appear until I fix them via a new SetNeighbors call. This is completely unnecessaryand this whole fiasco could be fixed with a simple couple lines of code in the AutoConnect method that allow it to exit early if there are no terrain in the scene with the Auto Connect option enabled, and also which would only clear the neighbors of terrain with Auto Connect enabled.

If a dev is on here and could respond it would be greatly appreciated!

[winter minnow]

@lusty pumice Your best bet is filing the bug report
I very rarely see unity staff commenting here, and I don't recall anyone talking about this issue before
...Besides you
Seems like you've been wrestling with this for a long time!

[lusty pumice]

Sigh, that is indeed the case. I never considered it a bug which is why I haven't filed it that way, but I guess that is the only path I can take towards getting it changed. Thanks for the advice, I appreciate it!

[shell jolt]

wdym? You can use any tree 3d models for your terrain

[edgy rampart]

can someone give me tips on making a scary terrain for a platformer 2d game

[vivid raven]

is this a good place to ask about 2D SpriteShape?

[winter minnow]

There probably is no "good" place for it, but it does count as a "world building tool" I suppose

[vivid raven]

alright, thanks

so, i was trying to set up a closed sprite shape, but i can't drag a sprite into the fill texture, anyone know what i'm doing wrong?

[cunning raven]

Hi Everyone, is there a way to tell HDRP terrain to display the normals further away? Right now the normal stops very near:

the green line is where the normal stops displaying

[thorny swift]

If you are using standard material that terrain comes from, enable instancing and then in material enable Per Pixel Normals

[inner willow]

Hi. My team is working on a fan-game based on a PS2 title, which requires extracting terrain quadrants from the original game. This terrain is made up of several meshes with different textures that blend together in-game. What would be the best approach for replicating this in Unity?

You can see here how the textures are meant to blend

[winter minnow]

They probably are meant to have a shader that fades them to transparency based on a mask map or vertex color

[inner willow]

Yeah, I believe they use vertex blending in-game

[cunning raven]

i have already active but it stil cuts the normal in the distancce like it has LOD somewhere

[thorny swift]

Hmm, either it does not get saved on material, make sure you created your own instance, using default one will often reset values on it. Next I can think of would be Base Map Distance (It may be falling back on lower level shader)

[cunning raven]

thanks for the tip! i have now my own but still it is cutting the normal in distance @thorny swift is there any other settings to overcome this?

[thorny swift]

np, I am running out, last thing was BaseMap distance, if that did not fix it I dont know if anything else that is not requiring you to write your own shaders will

[cunning raven]

alright, thanks a lot!

[thorny swift]

ur welcome

[tulip flare]

what does this texcoord means in terrain tools?

[strong dune]

Hello, does anyone know if there's a way to get the tile palette to straighten all the tile colliders? I have some that are taking the shape of the tile and it makes my character move up and down when running xd

[carmine river]

Maybe this isn't the solution you want but what if you just create a 3D cube, give it collision and make it invisible, then layer it onto the rocks?

[strong dune]

Yes, that's one solution I am thinking about but I also want to know if there's some tile functionality I don0t know

[verbal lichen]

Where can i find a good terrain palette?

[rain dagger]

what is a mask map?

i looked everywhere and there is no good or simple explanation

[winter minnow]

https://docs.unity3d.com/Manual/class-TerrainLayer.html mask map is explained along with other properties

[rain dagger]

I don't get it..

[barren oak]

In the sprite editor for each sprite you can set a custom physics shape for it

[cunning raven]

im sorry but try to use google

[winter minnow]

I can get not understanding mask mapping if you're not familiar with channel packing or non-color texture maps or with any other abstract shader concepts

But without knowing what the point of confusion is I can't really help

[rain dagger]

Oh dont worry spent whole yesterday researching texture mapping, i have solid grasp on the topic now :)

[rain dagger]

5.7k tris in size 500x500 terrain

vs 90 tris in 100x100 terrain

but when looking at the wireframe triangles.. it actually looks like the 100x100 has more triangles..and through testing, size seems to be the only factor.. any ideas? Shouldn't wireframe represent the triangle count?

[winter minnow]

@rain dagger Both of those look to be 16x16
Which amounts to 512 triangles, not 90 or 5.7k

[rain dagger]

then what's the stats window on about?

[winter minnow]

It's not usually accurate

[rain dagger]

hm

i think something definitely going on

[winter minnow]

Besides, looks like the terrain is not being rendered to the game camera at all in the second image

[rain dagger]

thats just cube position

as soon as i change from 100x100 to 500x500 the tris change to 5.7k

[winter minnow]

Things the camera can't see are not normally rendered

[rain dagger]

hmm lets check

!

that was the issue

still cant figure out why it says 5.7k tho

it should only count the amount the camera renders

which shouldn't be more than 100 imo

[winter minnow]

I don't believe the verts can be frustum culled individually

Either the terrain is rendered or it is not

[rain dagger]

in which case it should be 512 like you said

why is it 10x that xd

[winter minnow]

I simply believe that the stats window lies and don't worry about it unless it causes an issue that can be seen in the profiler

[thorny swift]

@rain dagger Triangle count gets multiplied by lights [as light also takes geometry in to render shadows], try disabling lights and see if your triangle count drops.

[winter minnow]

Good point

[rain dagger]

holy shit it dropped to 538

wut

[thorny swift]

basically treat each light with shadows as new camera, but this camera has its own culling, which can be even behind main camera view to give you shadows from behind you

[rain dagger]

damn, another layer of abstraction

optimizing will be hell

in the future

[thorny swift]

best is to use shadows only on main light, and use cookies for other lights to fake shadows. If you definitely need realtime shadows try to do it at smallest possible size and it should not spike to infinite

[rain dagger]

hmm, what i dont understand is i had a flat surface, so there were pretty much no shadows being cast, and still multiplied all the triangles by 5?

for what reason

[thorny swift]

you can check window/analysis/framedebugger to see what data did lights take to calculate them

[rain dagger]

what am i looking for

[thorny swift]

already there in Preview you see total number of Vertices/indices it too to calculate shadows, I believe its under Shadows.RenderJob where you can see each batch

[rain dagger]

lol its so hard to understand everything in here

i look up a guide on the frame debugger!

[thorny swift]

Yeah, go for it! it is not hard in the end but I understand why it can be overwhelming.

[rain dagger]

hmm

so what is this

[thorny swift]

you can see 4 batches of terrain chunks casting shadows (terrain is divided into chunks for culling speedups)

[rain dagger]

but the surface is flat D:

[thorny swift]

yeah, well either it is main light casting 4 chunks or if you have 4 lights with shadows it might be each light spanning 4 batches

[rain dagger]

its one light

how can i prevent this

its not even drawing shadows

idk why it does this

[thorny swift]

not sure tbh

[rain dagger]

np! learned a lot still (:

[winter minnow]

A lot of the time it's not worth spending the effort optimizing things that aren't causing a problem

[rain dagger]

For me it's to learn for future reference, not for the time being

[winter minnow]

The shadows are being rendered even if it's "flat"
I guess disabling shadow casting form the terrain mesh might help

[rain dagger]

ye that's the part im most curious about! It's not visible at all that any shadows are being rendered! Hence wondering why it's calculating shadows when none are present!

[thorny swift]

shadows are not rly per pixel if something wont cast shadows, turn shadow casting off

[winter minnow]

The renderer doesn't know whether shadows are being cast or not before it starts calculating them

The shadow map is still being drawn even if there's no geometry that recieves the shadows

[rain dagger]

there we go!

clicked

so if i use terrain as a flat surface should definitely turn shadows off

now imagine kilometers upon kilometers of terrain

not knowing this

huge performance cost

literally 5xing all tris otherwise

[winter minnow]

If it's flat, the vert count can be really low
If it's really flat, you may consider not using terrain at all

Vertex counts aren't a huge deal for optimization

Even mobile devices are starting to be able to render what, a million verts or more?

[rain dagger]

would baking the terrain lighting in this case reduce the tris count or does it not matter? (i'm thinking since the calculations are done prematurely)

[winter minnow]

Baking in what sense?
