I am using the TrackedCam_Unreal_Prev_3-Cam_3-Billboard Compound, and I do not understand the "use billboards" and "allow Virtuals" checkboxes. When I click on "Use Billboards" the captured video disappears from the scene and "Allow Virtuals" does not do anything. Where can I find info on these?
I think this new wiki page have more info about this topic
