Godot bug or my fault? Shader and Vertex!

Godot Version

4.4

Question

I want to move vertices using shaders, but something is very wrong:

  • Using a plane imported and subdivided from Blender makes the mesh look distorted.

  • Using a native Godot plane with MeshInstance3D works normally.

  • The imported plane works fine in Unity.

  • I’m using Godot version 4.4, compatibility mode.

    I need extra nodes?

I’m not sure if this is your case but check:
1 - Check if the original mesh was subdivided.
2 - Rotation of the imported mesh.
3 - If the mesh is double sided.
4 - If the faces of the imported mesh are properly oriented.

I zipped the project files in case someone wants to review them.

Thanks, but I don’t think there’s much to get wrong here. I just created a plane in Blender, subdivided it 100 times, and exported it — it doesn’t seem to be the problem.
1 - yes
2 - i not sure if blender rotation to godot keeps the same, or during export settings it changes like unity and fbx. i will look more into it.
3 - no
4 - yes

thanks.

Disable LOD generation in asset’s import settings.
