Right, those are my GTC slides… The problems mentioned there are:
- Light leaking: no improvements here, in fact with the new high-order emittance downsampling filter (bVxgiHighQualityEmittanceDownsampling in BaseEngine.ini) light leaking may appear in some places where it didn’t before.
- Voxels in reflections: nothing new here as well, you can still see the voxels in reflections on flat objects with low roughness. VXGI can add some jitter to sample positions, thus replacing visible voxels with noise, but that’s hardly better.
- Specular reflections are single bounce: not anymore, with multi-bounce support.
We do not make any distinction between static and moving objects, they are all processed in the same way. The improved emittance downsampling filter that I mentioned above helps with the quality of indirect lighting from moving objects a lot, and it also improves the quality of rough flat reflections.
