Luoshuang's GPULightmass

[Farshid]

The total number of samples taken by the Brute Force GI Engine is fixed:

Fast Preview: 16 * 16 * 2 = 512
Medium Quality: 32 * 32 * 2 (Fixed) + 32 * 32 * 2 (Adaptive) = 4096
Ultra High: 64 * 64 * 2 (Fixed) + 64 * 64 * 2 (Adaptive) = 16384

However, the secondary radiosity caching GI engine does accept a parameter to reduce/increase the quality: MappingSurfaceCacheDownsampleFactor (minimum 1) in BaseLightmass.ini. Basically the engine uses your lightmap resolution as a reference and divides it by the downsample factor to deduce the final indirect lighting resolution. Raising the downsample factor can reduce video memory consumption but can also introduce leaks. A workaround is to split the lightmap UV at where the lighting leaks.

========================

if .ini is impossible yet
can you make this hardcoded version for us ???

Ultra Ultra High: 256 * 256 * 2 (Fixed) + 256 * 256 * 2 (Adaptive) = 262144
