I'm using Gile[s] as my lightmapper and my engine can execute GLSL/HLSL scripts.
I would like to accomplish something like this for performance reasons. I was told that this technique can only be done by shaders.
Someone has provided me with a quick code example and starting code but it is still far from being implemented.
lightmapColor*=shadowmapValue; colorIntensity = (lightmapColor.r+lightmapColor.g+lightmapColor.b)/3.0; lightCol = (1-colorIntensity)*ambient+(colorIntensity)*lightmapColor;
Not sure if it is applicable in my engine so I am looking for some guidance and perhaps some basic hlsl code to accomplish this. My lightmap texture uses the UV2 Channel if it helps. Thanks.
