I followed the instructions from the VDC on builing cubmaps, or:
buildcubemaps
mat_hdr_level 0 (to go to LDR)
map mapname (to reload map)
buildcubemaps
mat_hdr_level 2 (to go back to HDR)
map mapname (to reload map)
except after typing in mat_hdr_level 0 or mat_hdr_level 2, i get a console message saying: "can't save multiplayer gaems".. is this normal?
