In the meantime, you CAN use OBS with a new "virtual webcam" plugin (so MFC/Flash recognize it as a source) but it does require some tinkering and a bit of knowhow. And it would still be at 800x600 max. I'd make a tutorial on that, but our Site Asshat (Jawbs) installed it for me and I don't have a step by step for y'all. Sozy.
(This is what I'll be using while we wait for the most recent bugs to be fixed. Everything was peachy earlier last week, but I think they implemented some code that has caused the more recent drastic issues.)
