I flipped the normals, so that I could see the meshes layered within the outer mesh by using blackface culling. Reversing the normals made it so that instead of culling the backfaces, it culls the frontfaces. I did this, following this tutorial: https://www.youtube.com/watch?v=H5edojx6DFI [I modified the center to suit the aesthetic style I was going for. However, he doesn't go over rendering in the video. I'm using Blender Render.
Is there anything I can do to salvage this?
