It would be really useful if Enscape could render out Alpha channels or even material ID in video mode.
I'm working on a walk through with a few cut a ways but hoping to have the site and context remain in the video.
So if it was possible to render the cut away with alpha mask I could paste it on top of the site video in post.
To get this effect now I'm rendering the cutaway video with a Chroma-Key Green Sky Box and using After Effect to key out the sky. Not even close to perfect but it looks okay.
