PBR / VXRT comparison

This is why I put so much effort into the voxel ray tracing feature. Without it, the sky reflection appears in enclosed areas and makes PBR rendering look very strange.

Can the sky contribute lighting to GI with VXRT? I mean like lighting the room through the window without directional light coming this way?

The "filling the room with light" kind of effect tends to happen mostly in the second bounce, I have found. Right now I am working with one bounce, because one thing at a time, but 2 bounces isn't too hard to add.

A third bounce, I have found, makes very little additional difference.

@Genebris Colored surfaces also don't reflect as strongly, which is supposed to happen. Here's what it looks like when everything is white.
