Last night before I went to bed inspiration hit and I just had to try and get this to work right and I tried and tried and tried until 'bout half past eleven and then I saw the render was just not working. No matter what combination of nodes I tried, it just wouldn't work, however, I knew it was possible.
So this morning after getting up and turning on my PC I just had to keep trying again and I think I finally have a good result in not only color mixing, but also overall depth. This is not perfect and can definitely be improved, but I like it so far:
(the video is a better example)
I also uploaded a video that you can download and watch it, using
this link(it's an OGG file and like the above you need Red/Cyan glasses to view it)
This will be my next free tutorial, so keep them eyes this space, lol.
Just as a note, this tutorial should be sound for creating full-color side-by-side as well, which I really should include, but since I can't really test it without possible royalties hanging over my head, it is only a maybe at this time.
When I release it, feel free to build on and improve it (^^,).
Obviously the color mix can be improved and this method isn't perfect, but this really works (still need to test it on a complex scene though).
Thank YOU!!!!!!!!!!!!
PS, This should also work with cycles, because it works with a finished scene, not a specific render engine.
