Valve Radiosity Simulator 4 threads [Reading texlights from 'lights.rad'] unknown light specifier type - lights [56 texlights parsed from 'lights.rad'] Despite having both a light_environment and light entities in my map, the map will load with fullbright. It was working for a while and stopped at some point without me noticing. I have narrowed it down to the above text being the issue, which comes up when compiling. It occurs with any .vmf I try loading up in TF2 that I have previously compiled using Hammer. Does anyone know how to fix this error? There are no leaks.
