Adjusting the Antialiasing of a Rendered 3D Model

Rendering engines such as Maya and Mental Ray output images in a format that uses a simple Z-buffer that does not allow for proper antialiasing around the edges of the geometry. Hence, it is ultimately better for image quality to render using RenderMan or Arnold if possible. Otherwise, if a different rendering engine must be used and there appears to be pixelated hard seams around 3D models, the Z Buffer Smoothing node can be used to smooth out the edges of the rendered model.
