I don't understand what I could be doing wrong. I have a vex variable export named multimatte that renders fine when I render on my machine, but when I render using an IFD it doesn't render the green channel. Has anyone run into this? Why wouldn't this vex variable be included in the IFD? I think it has something to do with the principled shader being included. When I remove that, both channels of my multimatte render fine.

Has anyone else run into this issue? I've attached my scene file. Any help would be appreciated.

Thanks!

The scene you attached works fine for me.

Thanks for checking that jsmack! I finally figured out what was happening. It turns out the farm I was rendering to had an older version of Houdini and the shader vex code was failing to compile on it. When I recreated the network on that older version and sent it off everything worked as expected.
