Digital Creator School shows how to quickly add worn edges to a model in Maya using Arnold nodes.
Making a model look used in a render is some careful attention to detail. Creating the worn look around the edges of a model is something that is easy to do if you work procedurally. If you are working with Arnold, there are only a couple of nodes that you need to add worn edges. Check out this short tutorial from Digital Creator School’s Lucas Ridley that shows us how.
Using Arnold Render in Maya and the Mix and Curvature nodes, Ridley shows how to put together a simple shading network that will automatically place worn edges on a model at render time. Arnold Curvature node uses samples within a range of an object’s edges and outputs a curvature. The node has attributes for adjusting the scope, falloff, and spread of the sampling. Anorld Curvature is excellent for quickly creating wear and tear, dirt maps and other effects.
