The exporter works fine, but when importing to Unity the lightmaps are not looking good, I’m using Unity’s Lightmapped/Diffuse shader, I’m new to Unity and any advice is welcome. I’m attaching the script:

unity as far as I remember has no modulate x2 / x4 based lightmapping which will cost quite a bit of quality. also you potentially need vertex colors enabled if you had vertex lit objects.
changing one of the present shaders should solve that 
thanks for sharing the code
Thanks for your answer, I’ll try to create a custom shader to test it.
