Rendering to channels

Documentation reads:

When ready, render shapes into the assigned channels with the Actions > Render
Shapes to Channels action.

I don’t have this option in 2021. What do I need to do to make it render into channels? I can see they are set up right in Silhouette…Alt RGB…it shows correctly.

@lamurillo We replaced the Shape to Channels action with a direct output on the Roto node. Sorry, I neglected to remove that reference.

Render shapes into the assigned channels by connecting the Roto node’s Channels output to an Output node. In the Output node, choose a file format that supports RGBA and make sure that
RGB and Alpha are enabled in the Channels field.
