You could try importing the default bricks (in 'SPECIAL' format) from Siba's Blender BLB/BLS plugin topic
It utterly wrecked the UV mapping. That's why I'm having to remap a lot of stuff.
I recommend that you use Blender 2.68 with the importer though because it works best there
Thanks Zeblote, and thanks but no Demain, I'm not making rectangular cuboid bricks.I've got everything about figured out, I think, aside from tgat I don't know if I need to set any special texture settings in Blender for the textures. Do I?
If you're exporting to BLB, no. Only the UV coordinates matter.
