Displacement problem - triangulation failed

Hi,

I have a pretty complex polygon character that i need to displace. Unfortunatly, when I apply a displacement map, Mental Ray gives me an error message, and the object is not rendered. This is the message:

GAPD 0.7 error 091035: Current triangles share vertices
GAPD 0.7 error 091036: v1 1.849082 0.729677 0.731716
GAPD 0.7 error 091037: v2 2.553731 0.214986 0.570937
GAPD 0.7 error 091038: Orientation of triangles inconsistent
GAPP 0.7 warn 092037: triangulation of polygon list from object ZombieShape failed

I tried to run a Polygon->Cleanup on my object, and it seems to be fine..

Any suggestions?

Are they conformed!
