Oups, this should be correct. glDisable( GL_FOG ); DrawLightmaps( ); glEnable( GL_FOG ); glBlendEquation( GL_FUNC_ADD ); glBlendFunc( GL_DST_COLOR, GL_ZERO ); DrawUnlitGeometry( ); glBlendFunc( GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA );
-- This way the second pass will set the destination to d1 = d0*s + 0*d0; which means it will just modulate the textured geometry by the lightmap. If you draw anything else after this you have to set the glBlendFunc again (eg see last line). The important thing is to disable Fog during the first pass otherwise it will be added two times.
