Important changes
- GPU Lightmass speed mode is no longer tied to viewport realtime. Instead, you manually switch between low and full speed.
- Interactive preview is now opt-in. Before this change, GPULM needed to allocate a big-enough pool (size controlled by GPULM Settings → System → Lightmap Tile Pool Size) so that it can contain all the tiles on your screen needed for interactive preview. The default value resulted in 55^2 tiles allocated which translated to ~1.5GB VRAM.
- Now if interactive preview is turned off, GPULM will only allocate the minimal amount of VRAM which is around ~200MB. GPULM will also switch to full speed automatically.
- If virtual texturing & virtual texture lightmaps are disabled, GPULM will disable interactive preview and switch to full bake as well.
