How to use multiple lightmaps for one Polygon? I need it for dynamic lightning, there is one Polygon effected by multiple light-sources.
My problem is: After use a lightmap with dark(0,0,0) texels this texels can’nt be made brighter by one of the following lightmaps. So a dark wall will ever be dark
Or is there a better way?
How they do this at Quake,Unreal…?
Thanks for every answer!
