Broadcast automation

hello everyone . I working on a studio and we had a virtual set , and there’s too many problems with automation , and “simple” things , such as , call other mesh or change the video on video wall , we had a comp and virtual camera , and 3 blackmagics cams one of them ,using trackvision as a tracker device , and i try to set the trackvision camera as my default camera , but i cant use the real camera as a controler , like on preview mode . its tricky and stressful to do all manual procedures on production days . Anyone can help? i saw the zerodensity app can do a lot of thinks , and the , so it can be done :smiley: . i hope you got some light for me , thanks
