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

Black blotches and cheeckerboard
I'm working on a static mesh, and well into the project I suddenly get this black blotchy checkerboard pattern on my skin (see attached .jpg - it's supposed to be all smooth blue, and up until a few hours ago it was). I have no idea why it happens, where it comes from, what it means, or how to fix it! (Or turn it off if it's a "feature"). Can someone please help me. I have lost a lot of good work, because my only recourse (so far) when it happens is to go back to an earlier version of the file before the problem occured.
I had this mesh almost finished. I saved the file and shut down Maya. When I came back after lunch and opened the file, my mesh is ruined. As far as I can tell none of the verticies have changed. I suspect (but don't know for sure) that it has something to do with normals, and I have looked in vain for something in the normals section of the program. About the only thing I ever do with normals is reverse them when I occasionally find them facing the wrong way (due to my own sloppiness).
Thanks in advance, I really need an answer to this. :headbang:

and normals>conform
normals>set vertex normal
then try normals>set to face
and if that doesnt work, try normals>soften/harden
it looks like a normals error to me...

I simply don't use the "Remove Geometry" section of the cleanup tool anymore, unless I have specifically saved the file before doing so. Probably a good idea anyway. Thank god for revision control.
