Which are the benefits of use multitexture in lightmaps? why not join the two textures in a new one in a program like photoshop and apply normal texturing?

lightmaps are often lowres, unique per face. textures are normally highres, reused on several faces. combining them means highrestextuers, unique per face. gigabytes of memory awaiting you:D

but if i have for example a scene with 3 textures of 512x512, the three with the same lightmap of 256x256, if I do multitexture I have 4 textures (3x512x512 + 1x256x256), but if I combine the lightmap to every texture, I get only the 3 textures (3x512x512)
where is the waste of memory?

well probably you''re talkin abt a best case scenario where u might be needing one texture per face and one lightmap per texture, then ofcourse there''s no difference, but be practical and see that most (almost all) of the 3D environments are not best case scenarios at all!

if you have the same lightning in all your room, thats not realistic... with your style , you must have all light in the center of the room (for equivalent lightmap).if it s the case, don t use lightmap, use vertex color!!!
