hi Pete,
you have to invert the normals or do some other tricks to illuminate the inside. check out this thread:How can I get a double sided texture? I've tried (backfacecull 0) and (hint-cull-ccw) - I'm trying to locate the camera inside a sphere with an Equirectangular image applied as a texture. I'm assuming that the default light would illuminate this texture even inside the sphere?
