This feature is Early Access.
Features available in Early Access give you the opportunity to learn how they work, plan your pipeline, and create test content. You should use caution when using these features in production, as we are still working to get to shipping-quality performance, stability, and platform support. We support backward compatibility for assets, and the APIs for these features are stable.

Compositing Material Nodes Reference

To make compositing easier, we've added a series of nodes to serve some of the most common compositing operations. Here, we briefly highlight each one, and explain its purpose.

image1.png

The compositing material nodes expect a float4 input, so make sure you’re passing in RGBA and not just RGB.

Over

This node layers one image (A) over another (B), using the alpha from input A.

image7.png

This node expects that the input color channels are pre-multiplied with the image’s alpha.

In

This node returns the portion of A that is inside the shape of B.

Out

This node returns the portion of A that is outside the shape of B.

PreMult

This node multiplies the input's RGBA channel by its alpha.

image6.png

UnPreMult

This node divides the input's RGBA channel by its alpha.

KeyMix

This node layers two images together using a specified mask.
