Hi! i’m starting to learn UE4 materials and VFX. I don’t have a solid foundation in math and other technical stuff - I’m trying to learn it on the way.
I'm interested in the technique that was used in that video in Unity (the link with a time-code): [https://youtu.be/dFv8lM-kS4E?t=98][1] They masked a cutted part of the mesh by a modifying normals of the inside mesh surface (two sided material), that is a hole in the mesh, to look like a plain, making an illusion of closed hole. I'm trying to replicate this in UE4 but unsuccessfully. Is it possible to assign the different texture on the hole(on the internal part of the mesh), that will look like ordinary closed surface with Base Color, Metallic, Roughness and Normal. Maybe something to do with Camera Vector and some kind of projection?
Сould you please give me some advice on how to do this. Is it even possible?
