Subject: Add a cvar: r_shadow_realtime_world_importlightentitiesfrommap
X-Git-Tag: xonotic-v0.8.5~88^2~113
X-Git-Url: https://git.rm.cloudns.org/?a=commitdiff_plain;h=e129d4fe60f23692aaa051b6c7cbc2fc1481e6b7;p=xonotic%2Fdarkplaces.git

Add a cvar: r_shadow_realtime_world_importlightentitiesfrommap

0: Never import lights from the .bsp/.ent file on map load.
1: Import lights from the .bsp/.ent file on map load if no rtlights are present.
2: Always use the .bsp/.ent's light entities, ignore rtlights files.
