Failed to fill alpha channel

I’m trying to render out my mattes as a .tif and I keep getting the error “failed to fill alpha channel” and then it will cancel the render.
Any ideas? Thanks!

Hi,

Can you go through the exact steps you are using to render out your mattes? It might be that something is missing.
