Yes. I want this feature so bad. I was so mad when I bought Arena and then found out I still needed to buy a 3rd party plugin for all my mapping needs. With this feature my C4D projects don't have to be exactly angled or sized. I can just map each side of my 3d model with an input slice and then correct it with the output slice. I like to do this because I'm always moving my stage/setup around different locations. I would love to do this entirely in Resolume.
It sucks because I know we are still along way from res 5
Oh well. Small gripe. Res is still the best program out there.
