Maya Error: incorrectly defined UV coordinates, missing uvlist or uvidxs

Maya Error: incorrectly defined UV coordinates, missing uvlist or uvidxs

When I do a current frame render inside of the Maya Render View the rendering does not work and I get the following error for several different shapes: Error: [polymesh] R:vario_touchpoint_lShape: incorrectly defined UV coordinates, missing either uvlist or uvidxs

I only get the error when rendering with the Arnold Renderer. The Maya Software renderer works without any problems.


Does anybody know how to fix this?


Thanks in advance!

Hello can you please uncheck abort on error found under diagnostics > error Handling  tab in the Arnold settings


also set verbosity level to warnings + info so we can debug what is going on a bit easier if this does not fix the problem!


see image bello for details

Thanks for the fast reply.

After unchecking "abort on Error" the render went through without any visible problems so far.

Thank you very much for your help!

Spoke too soon, just did UV Automatic, and works. Too much hacking on this mesh.

This is not solution for problem. Rather putting problem under the carpet. Is there actual solution? Or Autodesk just doesn't care?

Hi, I just found the solution. You should assign the right texture from your source images. Reload it and look if it is the right one in the project folder.

Check UV sets. Most probably you have UV set map1, default one, which is empty, while you aree actually trying to use the next UV set. Happens when you are creating UV set in other package, like Zbrush.
