VVIS/VBSP automatically tries to find gameinfo.txt if path not given

VRAD: -dumppropmaps dumps the lightmaps as .pfm during HDR compiles
•
VRAD: -dumppropmaps dumps files to /sp_lightmaps/ instead of base directory
•
VRAD: Fixed -dumppropmaps TGA output color range to be accurate with what is written to the BSP (also only writes TGA files for SDR compiles)

VRAD displays which lighting mode is being compiled in the log (HDR vs SDR)
•
Compile HDR .ppl files into the BSP, without overwriting the SDR ones and swap-in HDR static prop lightmaps when HDR lighting is in use in-game
