One Cube, one Projector and few Disadvantages

Hello Forum,
I am absolutly Newbie in VVVV, but after ReadAndTry I need to do Cubemapping. I don’t know if this is the right Patch, but it works in big Part. But it has some Disatvandages : in only one Side of the Cube i have the right Rectangle with straight Sides. In outher two Sides the Images goes Zig-zagy and that was I have are two rugged Rectangles with distored Images in them. That makes me impossible to draw Lines, who to walk for Example trough the Edges of the Cube. I will be vary thankfull if you tell me how to do this.
