Back to release list
VLM quality has been improved by picking cell positions in a more structured way instead of randomly picking points inside the cell (SSAO is disabled for better clarity in the corners):
This should resolve the issue where VLM cells that are very close to walls are very noisy even if a high sample count is used. Though, to avoid light leaks, your walls still need to be at least 2x the cell size thick.
Also, a bug related to backface detection has been fixed.
Update: there was a parameter issue and it has been fixed.
