VoxelGI - Help me to understand the issue!

Godot Version

4.6.1.stable

Question

I created a simple scene out of CSGBoxes and a single Light Source to check out the Light.
I want the red light to bounce off the wall parallel to it to enlighten the other walls (as seen in alot of VoxelGI/LightMap demonstrations). However, the other walls simply stay black, doesn’t matter what i do.

I did bake VoxelGI. I also tried to apply some material (didn’t do any difference). I also played around with the Light settings and so on. Switched Mode from Static to Dynamic in CSGBoxes > Global Illumination. Nothing made a difference.

Can someone please tell me what I forget or don’t understand, before I get crazy? :frowning:

If you have a WorldEnvironment node in your scene, maybe try changing the background color, which is usually black by default.

I have never tried VoxelGI with CSG geometry. Maybe that is the problem? I would export your CSGs to Blender and export them as a real geometry. Do you have the same problems with them, too?
