Is Dif Lightmapping working in T3D?

Hey Everyone, I wandered around for a while but didn't find any forums/threads/posts regarding this, but I don't seem to be able to get lightmaps working with DIFs in T3D as I did in TGEA. (They load fine, everythings seems correct but no baked lightmaps).

I know that DIFs are depreciated, just curious if A) I'm doing something stupid B) It's a know issue and I just missed it C) It's a depreciated feature and I'll just have to get over it. =)
