Strange Geometry

Recommended Posts

Could someone help me, I'm desperate.

I have a sub d model that looks fine in the viewport until I view mantra.

I see strange geometry flying out to unknown areas.

I have turned on 'points' and there appear to be no stray points.

Is this a rendering but with sub d models?

It sounds like the model itself, but I do not know where to begin.

Thank you,

Chris S (SARS free Toronto, 0 days.) :ph34r:

Do you have any displacements or shaders applied to it?

Marc taught me this once: Turn on your primitive number display and check for zero-area polys on your geometry. If you see two primitive numbers on top of each other, follow up with a Blast SOP and type the number of the bad primitive in there. Sometimes a Facet SOP with "Remove Degenerate" turned on can help too - or the Clean SOP.

The SubD algo kind of freaks out with zero-area polys and its pretty easy to get em if you've clipped your geometry in order to redo the symmetry (say, clipping a head in half to mirror it)

Hope this helps,

J
