GeNa Pro 3.3.16 - Road Carve Issue

[gabriel_fuentesGD]

Hey guys! I've been using GeNa Pro (3.3.14) to make some roads for my environment, didn't had any issues during that version. However, when I updated to the recent version (3.3.16), carving is not working as intended, the preview is not appearing and I'm getting the following consistent error every time I press the carve extension:

"GeNaCarve.compute: Kernel at index (0) is invalid
UnityEngine.StackTraceUtility:ExtractStackTrace ()
GeNa.Core.GeNaCompute:Dispatch (int,int,int,int)
GeNa.Core.TerrainTools:CarveTerrain (UnityEngine.Terrain,GeNa.Core.GeNaSpline,System.Collections.Generic.List`1<GeNa.Core.GeNaCurve>,GeNa.Core.TerrainEntity)
GeNa.Core.TerrainTools:GenerateTerrainEntity (GeNa.Core.TerrainModifier,GeNa.Core.GeNaSpline)
GeNa.Core.GeNaCarveExtension:Visualize () (at Assets/Procedural Worlds/GeNa/Scripts/Runtime/Extensions/GeNaCarveExtension.cs:138)
GeNa.Core.GeNaCarveExtension:OnSceneGUI () (at Assets/Procedural Worlds/GeNa/Scripts/Runtime/Extensions/GeNaCarveExtension.cs:95)

GeNa.Core.SplineEditor:OnSceneGUI () (at Assets/Procedural Worlds/GeNa/Scripts/Editor/SplineEditor.cs:156)
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)."

Any advice or suggestions is greatly appreciated!

 

Carving extension working as intended in version 3.3.14:

 

Here's the carve extension in version 3.3.16 in a test scene with the consistent error and the preview not working properly:

The terrain also resets to zero. Here's another image of the terrain:

Hey @gabriel_fuentesGD,

I actually havent seen this issue in so long. I was wondering if you could provide me with the following details:

• What OS are you using to run Unity.
• What version of Unity are you using.
• Does the computer you're using support compute shaders? 

If you're unsure of how to find out about whether your computer supports compute shaders, since you have Gaia installed, could you open the Gaia Manager, go to the Advanced tab and open the System & Project Information panel. You should see that information here:

Also, if this is related to another issue that I noticed with Unity, you could try disabling the 'Caching Preprocessor' setting located in Edit -> Project Settings -> Editor -> Caching Preprocessor:

Hey @Manny,

Here are the general details for my Unity version and my computer:

I also turned off the 'Caching Preprocessor' setting and I'm still getting the error. 

Testing with some of my coworkers, we discovered that the problem does not occur on their computers. So most likely it can't be neither the GeNa nor the Unity version, rather it has to do with the computer perhaps?

Hey @gabriel_fuentesGD,

It looks as though that compute shader that is being used, isn't being compiled by Unity. Could you please select that shader and send a screenshot of any warnings that are showing?

The shader is located in Procedural Worlds -> GeNa -> Resources -> Compute -> TerrainTools -> GeNaCarve.compute

@Manny So looking at the shader, I'm getting the following errors:

However, I do have that file in the project.

Update: 

I managed to solve the issue! By looking at those errors, I was getting the 'Couldn't open include file' . Apparently that's an issue that has happened to multiple people before when using shaders. What worked for me was to:

1. Rename both 'GeNa Carve' and 'GeNa Paint' scripts (to anything literally)
2. Right click and re-import both files, and rename them again to their original names
3. After that, try closing Unity and re-opening the project. That should fix the issue

Here's a link of a forum of multiple people having the same issue but with different shaders:

Thank you for the support @Manny!

That's fantastic to hear mate! Thanks for providing us with the resolution that worked for you 😁
