Hello i have the latest version of community DE, and started a new project. I learned that using Allow virtuals = OFF on my Billboards gives me the best quality for video input.

But i would also want to place some objects in front of my talent so that i can have a better composition, and establish, and ground the talent on my virtual set.  I don't fully understand how to use Bmask or when its enabled, sometimes i get "NO VIDEO OUTPUT" and my main problem is that when is enabled the Bmask looks all red. A little documentation on this would be greatly appreciated or at least a mini tutorial on how to place objects in the foreground.

Am I missing something on my project? can i select specific objects?

Thanks a lot, really like aximmetry!
