Great stuff.....thank you!
In this scenerio (L14 projecting matte paintings) though,
it would be easier inside fusion, to create a simple 3D shape, scale it up and resize the y-axis...
if you place the projector and the camera inside the shape you can simply use a bender node to transform the shape to
it´s final state....
sorry for the nerdy comment 😉
eager to see more of your tutorials, really!!!
