Hi, just wondering if anyone could point me to a resource for lightmap generation. I need an algorithm for the texture packer - the code which generates lightmap texture coordinates and packs the lightmap into one texture. cheers

You can use a kD-tree approach for packing lightmaps: try this link.

HTH,

thanks!

I suppose that the algorithm could be adapted to use triangles rather than quads by replacing the quad with the bounding rectangle of the triangle...
