Hello! I have been searching online for a solution to creating an image plane to create an alpha matte. What I would like to do is get all the objects from my scene and have a separate black and white alpha matte for each object. I would like to be able to take the image into photoshop/after effects and be able to manipulate all the objects in my scene separately. I have followed the video below but this becomes quite the process once I have many objects in my scene. Ideally what I want is when I make an animation sequence that either the exr has layers with all the alpha mask or when I hit render it renders both my image and the alpha's as separate sequences. I also tried using this technique http://houdinitricks.com/matte-objects-houdini/ but when I activate the matte option it still renders the rest of my scene normally with only my object appearing in black. I just want a black and white alpha matte.
