I'd like to request a feature that allows users to export output masks and slices to .eps or layered .ai files.
I recently did a setup here (in Zimbabwe) mapping onto a wrapped truck. The projector position and the car weren't easy to move around. I used masks in the output window to map out the different parts, lights, doors, wheels, etc; I took a screen cap and used this referrence to create animations. Ideally, I could just export the mapped masks and skip the extra step of retracing (with the inevitable mistakes) the screen caps. It's particularly useful when simply masking videos won't work because you're using effects in AE that reference masks.
