RGB Object&Material ID Node

Description

I made a Node tree for exporting Material and Object ID passes as a flattened RGB image for compositing in After Effects, because i could not figure out an easier way to do this using open EXR which i thought would work but does not seem to.

Hope this is useful to some.

Append the ID Mask Combine Node group to your scene and just plug in your Object or Material ID pass into the node,

IT supports up to 10 different object/material index inputs and flattens it into an RGBA Image

Good point i will rework it, Still wish they had a better index ID output as a single file using OpenEXR or something , The only reason i do this is for other people to use so they dont need to download many different Masks, it works alright but I also need to make a clearer difference between the colour.
