View Full Version : Mental Ray Problem

05 May 2007, 07:53 PM
I have a shader in mental ray that is giving me some problems.

Its got color, specular, bump maps, incandesence (with a sample info do get facing ratios), transparency (with facing rations), and refraction.

My problem is that in my scene one of my objects engulfs another creating a bubble with this engulfed object inside it. My shader doesnt seem to like to double up on itself like you're looking through it twice, and as a result the object inside the bubble, when viewed through the surface of the first object, is invisible. If I go under-neith the skin of the engulfing object and look at the bubble from the inside, however, it works.

I really need the camera to stay outside of the original object, though. Any ideas? Pics attached.
