I made a map using displacement terrain to create a hillside. Looks good in Hammer, no errors found, compiling goes smooth... However, when I try to runthe map... I get this error:
MaterialSystem_Interface_t::AllocateLightmap::lightmap (516x66) too big to fit in page (512x256)
And then an error saying HL2 has crashed. I tried adjusting the Lightmapscale. Doesn't work... I'm going nuts here, can someone PLEASE HELP ME??
