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

Non manifold Geometry

Hello all,

I have a question about splitting polygons. In the Maya Fundamentals tutorials that came with the book the author mentioned avoiding non-manifold geometry. He described this as a polygon with more than four sides. (then he said five in a different tutorial.) What affects could non-manifold geometry have on a model during the different steps in finishing it? i.e. modeling, animation, coloring, rendering. I know how to avoid having this type of geometry but am not completley sure why I should be avoiding it.

Some functions won't work at all or they can produce weird results if your model has non-manifold geometry. Non-manifold can mean that one or more polygons has a different normal direction than the adjacent ones. It can also mean a polygon with less than 3 vertices or some loose vertices without any edges connected to it (and many other things). I like to think that non-manifold geometry is a synomym to illegal geometry...
