I have very big mesh around 4 mil faces with multires, and displacement on top, and I want to cut one little part out. Edit mode is unusable with that polycount, and when I tried it it destroys displacement shader. Boolean modifier also leaves artifacts and displacement looks horrible on the cutted edge.
So I came with the idea of ‘cutting’ one mesh with another using shaders. Is it possible? The object that I want to cut is essencially a plane (white on mockup), so I dont care about the inside of the mesh.
