Common Uses

...

The SamplerInfo node extracts particular information about the scene. It then converts the gathered information into RGB data. It can be used within the Maya Hypershade or to drive a material channel to achieve various effects. This can provide more render passes with information that can allow more possibilities to editing during the compositing process.
