If you can include a wad demonstrating the problem, please do so. Bug reports that include fully-constructed demos have a much better chance of being investigated in a timely manner than those that don't.

Please make a new topic for every bug. Don't combine multiple bugs into a single topic. Thanks!

Voxel models are too dark when Ambient Occlusion is enabled.

I believe it's because voxels don't have normals which are used by SSAO shader.
How to reproduce:
- Download and run any wad with voxels.
- Toggle Ambient Occlusion on/off while looking at voxel model(s).
Possible solution: render voxel models with invalid normals, e.g. vec3(0,0,0) or vec3(0,0,-1), and filter out pixels with such normals in SSAO shader.
