Dlights affect the lightmaps, elights do not. Both are supported on all hardware source supports.
Dlights can be turned off for performance by using the convar r_dynamic. By default, HL2 sets r_dynamic 0 for dx7, but you could turn it back on in your mod (although the user could still turn it back off). > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of Imperio59 > Sent: Tuesday, May 24, 2005 9:13 PM > To: hlcoders@list.valvesoftware.com > Subject: [hlcoders] Using Dynamic Lights: AllocDLight vs > AllocElight and hardware compatibility > > Ok, > In the past few days people have been asking after seeing > some of our in-game videos about dynamic lights and their > overuse.
