Actually... there is an issue in my transparent PNG above: the eyelashes transparency shader. The alpha on this shader is cutting a hole in the figure (if you look at that PNG in Ps or whatever you will see the problem). Fringe around the eyelashes.... Assuming what we all want is a way to composite our uRecordings as a layer of video, maybe there can be a way uRecord could determine whether a transparent shader is/is not occluding another object? Thank you for looking into it!
