Multi pass is probably the only solution that will work for this image if I truly want GI in it. I really had hoped there was something more to GI than just caustics or indirect lighting which would have been a significant improvement over raytracing. To finalize this image will take a lot of restructuring of textures to pull out all the glow for the GI render. I'll try to apply 3D aura to one of two objects glowing in a scene. I'd really like to be able to accomplish that! -Kix
