Topic Starter	Topic: Modifying GtkRadiant to render quake2 lightmaps in quake3
lukesmith Gibblet Joined: 20 Aug 2011 Posts: 21	Posted: 08-20-2011 12:21 PM                  Hi, I have a copy of the source code to GtkRadiant 1.5. I was just wondering how easy it would be to export a map with radiosity lightmaps like the ones used in quake2 but to save everything else along with these lightmaps in the quake3 bsp format. Im guessing this is fairly straightforward as the editor already can render these lightmaps for a quake2 map. This would be done in relation to a bsp loader I have written so I would then accomodate for the fact that it is no longer a greyscale lightmap. Could anyone point me in the right direction with this?

Most mappers use q3map2 which is a highly optimized and improved version of q3map. Maybe the sourcecode to that is available.

I just read through it and it calcualtes the lightmaps in greyscale as its for quake3. There doesnt seem to be a q2 version of this in the quake2 sourcecode. Does anybody know where I could find sourcecode for how quake2 calculates the color radiosity lightmaps?
