Krzysztof Narkowicz	f94472aea1	Lumen surface cache compression ... * First all cards are allocated to a temporary atlas of fixed size set by r.LumenScene.CardCaptureAtlasFactor * After cards are captured into temporary atlas, they are compressed into final BC compressed atlas. Compression can be disabled with r.LumenScene.SurfaceCache.Compress * Atlas clears were also converted to support clearing compressed surfaces * Atlas capture operations work on uploaded rect list, instead of a GPU generated card list * Renamed r.LumenSurfaceCache.* to r.LumenScene.SurfaceCache.* * Renamed LumenSceneLighting.usf to LumenSurfaceCache.usf * Renamed LumenScenePrefilter.cpp to LumenSurfaceCache.cpp Cuts down VRAM memory usage by 160mb Compression performance on console: ~0.18ms for 1M texels (~0.9ms with UAV aliasing path, which is currently disabled due to missing pieces in RHI) [CL 16160800 by Krzysztof Narkowicz in ue5-main branch]	2021-04-29 15:30:04 -04:00
