QRAD (short for Quake RADiosity) was one of the sets of tools originally shipped with the Half-Life mod tools to compile radiosity and lightmap data into a map.
This was one of the most bugged tools out of the original sets of tools. ZHLT found that this tool packed the direct lighting data into a map twice resulting in longer compile times. He also found that every PVS required a light_environment (can be only seen in decomplied map files from some games) for lighting an outdoor area, which could be tedious for mappers.
Trivia
- Even through Half-Life 2 used VRAD (which does not have the light_environment PVS issue), when decompiling all the maps or download a leaked VMF version of the map, many maps (atleast prior to 20th anniversary) contains multiple light_environment on every PVS.
