Hi

Gap will appear in some place in vlomnutric lightmap, and can not avoid by adjusting settings.

Check images below, taken by forcing subdividing all cells and not discarding and bricks.

Comment the function “TrimBricksByInterpolationError” called in file “ImportVolumetricLightmap.cpp” can prevent this problem. Seems the problem caused by array read overflow in function “FilteredVolumeLookup” (brick(0,0,3.5) needs to be filtered between (0,0,3) and (0,0,4)).
