Alpha channel and shadow catcher

[Ceciliabr]

Hi, and thanks for a most useful and elegant app. I have been using sh3d for a couple of years now, and it feels like I have gotten quite familiar with how it works.

I was wondering, since I know several users are using this app for making illustrations (that's how I learned about this program in the first place), if it would be possible to include an option for making the sky into an alpha channel, and at the same time making the ground into a shadow-catcher only, since the problem with using green or blue solids for texturing the sky and the ground, is that the color is reflected in windows and other reflective surfaces, which makes it hard to use chroma keying in the post processing where we often have a need to place our house (or whatever we have created) in a landscape or an environment that can not be produced by sh3d.


Well... just letting my mind wander...
