I've been playing around with vMixHD this week, which has a lot of potential as a bargain-option Tricaster.
It includes the ability to import virtual sets. I have a virtual studio I've built in C4D to match our school's location, branding and studio layout. (We have a medium-sized green-painted room with two cameras). The set has been used in the past as a four 2D stills (close up and wide for each camera - manually coordinated). I'm not expecting to fly around this set in true 3D.
Is there a method / export option for taking this set and exporting it? I believe vMix can import sets designed for other video switcher programs.
