I have shot a footage and got a pretty good track/solve error. I deliberatly shot it so that there is a real life object in the way of where I want my 3D objects, and I want to model that box (it is simply just a box!) around the real life box, and then hide the other 3D object.
But I can’t figure out how to do the masking.
I have googled for several days to find a decent tutorial on how to do this, and I can’t find any. Please help me, or provide some decent instructions for a newbie like me.
