Weird, Bloated renders in mental ray

Hi all. Using Maya 8.5 on a Precision 690, OS: XP Pro, 2 Gigs RAM

OK, I am doing a render of a scene which is going fine, except one piece of geometry renders as though it were somehow ridiculously inflated or bloated. It's a subdiovision. I have tried rendering it as a straight polygon, but it then appears semi bloated but also it looks shredded and torn or fractured.

When rendering as a subdiv the script editor provides this message after it completes the render:

"Warning: (Mayatomr.Geometry) : pasted__pasted__polyToSubdShape22, subdivision surface contains creases on boundary edges which are unsupported and have been ignored // "

Does anyone know how to fix these "creased" boundary edges which seem to be related to the strange, extremely bloated rendered geometry?

Any help would be most welcome.

Thanks, T

Post an image of your render, so we can see;
Most people get bloated renders when using displacementmaps in combination with wrong settings

Try unlocking the normals, under Normals-Unlock

Keep it real.

Hi guys. Thanks very much for the help. I've been busy with other things and haven't had time to sort things out.

I think it is a displacement map problem.

This is a mesh I had made several months ago then left it to do do other things, then returned to it just last week. Now I recall I did make a map in ZBrush back when and then started having problems when I put it on the poly but forgot about that in the interim.

I will examine the situation more closely when my schedule opens up, but wanted to thank you both for the help.

Tristan
