terrain set height feature slider is broken and useless

Hi,

The slider for set height goes from 0 to 2000, yet my terrain originates at -256..... so you can see how hopelessly useless this slider is.

But, shift+click to sample will work, if a bodge workaround.

Hoping UI team or something will find out about it.

 

I just checked the code. Looks like a bug. Slider goes from hardcoded 0 to terrain.terrainData.size.y.

 

Doesn't go to terrain size y here just hardcoded at 2k regardless.

 

Even shift + click not working for me. Also it's annoying I can't make pit lower than terrain height. I need to rise ALL terrain, than use lower brush. This is all so uncomfortable.

 

Sorry for my ignorance, but where is the script for the terrain height located? I am having issues as well regarding my terrain max height and would like to tinker with it a bit to see if I can fit it. Currently, my terrain is at a 0.2:1 scale, so the height is rather small, using float values to do the height. (needed to be done for draw distance on terrain details)

 

It's an internal script. What you can get is the one from the C# reference:

https://github.com/Unity-Technologies/UnityCsReference/tree/master/Modules/TerrainEditor/PaintTools

Although that's from 2018.3.0b12.

 

But didn't that behaviour change with the new versions of unity? (I'm currently on 2018.3.7f1)
In previous versions, "0" was the terrain's 0 (meaning that if your terrain started at -256, 0 would be -256) but now it became an absolute value. Or am I missing something?
It's really really annoying not being able to use set height under 0 and having to lower the height manually...

 

I just did a bug report about the terrain issue (1150178)

Set height and sample target height on terrain is broken

1. What happened

It's not possible to sample the target height on a terrain if the Y axes is not between 0 and 600
That happen since unity 2018.3.7 and still happen on 2018.3.14

2. How we can reproduce it using the example you attached

Step 1:

• a. Create a terrain, make sure it's 0,0,0
• b. Use the "set height" tool and raise the terrain
• c. Hold control and click to sample the height
• d. draw with it and it works as expected

Step 2:

• a. Move the terrain to 0,-250,0
• b. Use the "set height" tool and raise the terrain
• c. Hold control and click to sample the height
• d. the sample height stay at 0, it's not possible to pickup the height

Step 3:

• a. Move the terrain to 0,700,0
• b. Use the "set height" tool and raise the terrain
• c. Hold control and click to sample the height
• d. the sample height stay at 600, it's not possible to pickup the height anymore

 

Can just agree to that. Set terrain height tool is broken in 2018.3.
Have you filed a bug report for it?

 

yes, Unity listed it as an issue

Damn this is annoying. 3 months and no fix for this?

The Flatten button is broken. It does some kind of world space adjustment and doesn't take into account the current terrain Y position.

Workflow:

• Set terrain height to 512 (Terrain Settings > Mesh Resolution)
  
• Flatten to 256
• Move to 0, -256, 0. Now the ground is the "middle" of the height, so we can create 256 deep water and 256 high mountains.
• Flatten to 256 again. The terrain disappears from the screen. You have to move it to -512 to find the ground, but you can't paint the terrain higher. Flattening to any other number does nothing.

I have no idea what signed height values are, but if we didn't have them with the old terrain then it should be no different.

 

Agree, flattern is broken and unusable, and you can't even set terrain on some height and than lower some parts, because negative values not support. It's make terrain editing almost impossible.

 

Just move terrain object somewhere down or up and Set Height brush already do things wrong.

 

@wyatttt I took a brief look at the code here:

https://github.com/Unity-Technologi...les/TerrainEditor/PaintTools/SetHeightTool.cs

It seems like the variable

Code (csharp):

1. m_HeightWorldSpace

is being considered using the terrain y position, e. g.:

Code (csharp):

1. m_HeightWorldSpace = terrain.terrainData.GetInterpolatedHeight(editContext.uv.x, editContext.uv.y) + terrain.transform.position.y;

However, in the inspector it's being clamped between 0 and the terrain height:

Code (csharp):

1. m_HeightWorldSpace = EditorGUILayout.Slider(styles.height, m_HeightWorldSpace, 0, terrain.terrainData.size.y);

ie the terrain's y position is missing in the inspector min and max values.

 

is there any update on that?

Finally!
This is great news, thanks!

 

Hello @ChrisTchou, we're close to release, will it be fixed on production ready versions of Unity?

 

Thanks that works @ChrisTchou

 

Buenas tardes, me gustaría comentar que todavía tengo problemas con la herramienta SetHeightTool, y de hecho ya he probado las siguientes verificaciones y no me ha funcionado en absoluto. No puedo hundir el suelo más allá de su altura a menos que primero eleve todo y luego lo hunda, probé con las verificaciones:

2020.1.0a3 (alfa)
2019.3.0b4 (beta)
2019.2.6f1 (último oficial)
2019.1.2f1
2019.1.1f1

Si alguien tiene una solución o consejo, lo agradecería mucho, ya que recién estoy comenzando en esta área

Buenos días a todos y gracias por la atención prestada

thank you human I'll keep it in mind for the next

 

Good afternoon, I would like to comment that I still have problems with the SetHeightTool tool, and in fact I have already tried the following verifications and it has not worked at all. I can't sink the ground beyond its height unless I first raise everything and then sink it, I tried the checks:

2020.1.0a3 (alpha)
2019.3.0b4 (beta)
2019.2.6f1 (last official)
2019.1.2f1
2019.1.1f1

If anyone has a solution or advice, I would greatly appreciate it, since I am just starting in this area

Good morning everyone and thanks for the attention given

[QUOTE = "wyatttt, post: 5008646, member: 1809376"] Creo que este bit es un tema separado y desafortunadamente así es como Heightmaps funciona actualmente en Unity. Los mapas de altura almacenan valores firmados, pero tratamos los mapas de altura en terreno como sin signo para que esos valores no puedan ir por debajo de 0 (lo que termina siendo una altura local de 0 y, por lo tanto, la posición y del objeto de juego de terreno) [/ QUOTE]

1: thank you very much for responding
2: Then I should open a new topic?
3: does that mean there is no way to fix it? I ask why ChrisTchou commented before it was resolved in the 2019.3.0a11 version and it is not working as it should

How do we fix this for 2019.2?

 

My terrain somehow works like this. Unity 2019.1.13
For both Set Height Brush and Smooth Brush.

Works fine when I create new project. But on my current project even after deleting all the tools I downloaded this won't get fixed.

 

Hey, since there is some activity here on this thread. Did you guys know that terrain data is not checked of version control when edited (All other assets I have found do). You have to manually check out and check in.
