View Full Version : Rendering geometry cock-up

Hi - does anyone know what this is..?

I've tried deleting the edges (no effect), rebuilding in U and V directions (no effect), converting to Polys (it's modellied in NURBS) and to SubDs (gues what..? No effect)

Please help - it doesn't show up on the 3D view - only when rendering.. what is it, how do I fix it, and how do I avoid them in future..? I've just spent 4 hours modelling a head and I don't really fancy doing it all over again..!

OK, here's the same geometry, all pieces blended and attached.. Same problem. Please help!!

you've probably tried this but after converting to poly did you try attaching and manually merging all the vertices along the middle? That should get rid of that line.

YEah, I've tried that.. still no joy. The original geom was NURBS, and the line was actually there in when it was a Nurbs shape, too.. I've tried everything in ALL geometry types, and it STILL doesn't work...

:annoyed:

This sucks.. I don't want to rebuild this AGAIN!!!

OK, panic over - I converted to Sub-Ds and then deleted history and converted back to polys (and tried again to Nubs). It works fine, but I have NO idea what it was!!

So - tip for anyone with this sort of problem.. convert around, and see if you can whip it into shape!

Cheers

might have been fixable by adjusting the normals on a poly model...

I tried the normals too... It LOOKS like the vertex normals are out of whack or something, and the only way it appears one can fix that is to rebuild the thing completely. I'm not 100% on this, but I tried every tool in the Polygons menus, including "clean up"..

I also had the exact same problem when it was converted to SubDs.. and the original object was a NURBS geom, so I have NO idea where it came from!

PS - it has sort of reappeared on the completed head - not in the same place, but along the seams of the rest of the skull.. I have no real idea what causes it, but it looks intermittent.
