Our output pipeline requires us to render out separate image sequence for the Alpha Channel. (deliver RGB(dpx) and Matte(srgb))
In RV, I coded via python, the ability to import the final render, the plate, create stacks of each pair and then take all the stacks and make a single sequence.
What I would like to do is also load up the Matte renders (already implemented), but instead of adding the Matte render to the matching stack, I would like to shuffle the Alpha Channel of the Matte Render only into the Final Renders Alpha Channel. So our producers/supervisors can use (Shift+)) to toggle between the sources in a stack, but also then press "A" and view the alpha of the Matte.
Any tricks to make this possible?
