Maybee if the three lights were inside a circular dome or, as my softbox idea.

 

If you email me brimar@jbr.com.au I will send you the softbox car file to experiment with.

Actually, photographers use a complete box but, as no background reflections occur  in 3d my setup seems to work quite well.

Ps I will do an exercise to see how it goes with Vic. and post.
