Point projection onto rectangular mesh

Thanks for your reply!

I’ve got the idea and I have actually tried this one. Faced some problems with turning the meshes so the direction of its’ faces are in needed direction but solved it eventually.

Another problem that i’ve got with raycaster casting on the plane from any origin is that sometimes the intersection point may not be correct (due to precision error). Tried to explain it in this question. Do you have any ideas how I can deal with it?

Thank you!
