Ii got a situation where i need to roto a layer. This layer is a background which is a landscape, and because i got some buildings over in different layers i need to roto some of the background to place over these building in order to blend them with the background.
So basically what i did was duplicating the background and put over the building. But because this duplicated layer needs to be in 3D when this transformation is applied , the scale changes. Later for adjusting this layer in order to have exactly the same size than the original background is almost impossible.
