Gile[s] tips?

[3DModelerMan]

Does anyone here use Gile[s] and 3D World Studio? The 3DWS lightmapping isn't cutting it for me, so I looked into Gile[s]. I'm trying to figure out how to get my level geometry to Gile[s] correctly. I've tried just importing the b3d file directly from 3DWS, but something is going on with it. Does my graphics card have to support OpenGL GLSL shaders for Gile[s]. Or does anyone know about other lightmappers that are better?
