Hello,
this is my try to make first modifier in maxscript.
It take one mesh “Mesh” and hit rays from every point to another mesh “UV”. Then it moves points where it hitted the “UV” mesh but on “XY” mesh. “UV” and “XY” should have the same topology. As “Mesh” and mesh with modifier (references )
It is basic but slow. How can I make it faster? thanks

Probably I should ask “How to do it right?”.
