Introduction to Maya - Rendering in Arnold
This course will look at the fundamentals of rendering in Arnold. We'll go through the different light types available, cameras, shaders, Arnold's render settings and finally how to split an image into render passes (AOV's), before we then reassemble it i

Strange Proxy Subdiv problem

I have a geometry which has some sort of corruption in it. It's a clean, all quad polygon piece with a subdiv proxy attached. When I apply a smooth node to the master geometry to use the sculpt on geometry tool, the proxy instantly shatters in to a collection of detached, spread out quads loosely forming the shape of the original.

Also, if I am working on the original geometry, just moving vertices, the proxy responds normally. However, if I start using the split polygon tool (temporarily creating 3 or n-sided polys) or insert edge loop tool, the proxy will open holes in itself around the corresponding areas.

The one other geometry in the scene is fine -- the proxy for that one behaves normally. Just this one, main geometry has these problems. I have deleted history and all that but it doesn't help and I don't know what to do.

Anyone know how I can get rid of the corruption in this geometry?

Thanks for reading, Tristan

New Wrinkle...

OK, it seems that if I create another, clean poly and then Mesh --> Combine it with the troubled one, then this new geometry works fine. Proxy for it behaves as it should. If I then, separate these again, the old geometry has the same subdiv anomolous problems described at the start of the thread.

Anybody know what's going on?

When you create a proxy, it puts the smooth and unsmooth version on top of each other. Maybe thats what you're seeing.

Could be.... I found that to fix the problem, all I need to do is reassign the shader to the proxy and it works normaly again. Quick solutions are the best.

Thanks everyone.
