In our theatre we have a play now, that utilises two chairs. The chairs are shaped like an inverted U. I would like to follow the example in the tutorial "Sending multiple videos from Modul8 to MadMapper". I succeded in that.
You can see through the legs of the chair. That means the projection part on the middle of the chair also projects on the backdrop. If i do a mask I get a black square instead on the backdrop.
If it was possible to have more points on a quad surface I would have solved my problem. Or make a mask that can be turned into a surface.
