That is a very good approach! Thanks for your answer!
My final goal is to implement this parallax (see video below) and this discussion in a simple blueprint, since I have no C++ experience:
If I understand it correctly, the blueprint always goes from left to right, from input to output.
My idea would be based on your answer:
Get Camera View → “Calculations between desired view projection offset and minimal view info projection offset” → calculate projection matrix → Get … plane
However, after that I think a set function would have to come. Something like “Set Camera View” to distort the view. But I can’t find a set function.
