Changing material parameter for material instance directly on the mesh in the editor

True, but what you are suggesting is EXTREMELY inefficient. You WANT as many things using the same material as possible, it’s one of the main ways of improving performance in any game. If you want per-instance dynamic material instances you want to create a Blueprint encapsulating that functionality with exposed parameters.

This is actually EXTREMELY wrong. Changing the material parameters doesn’t mean you are changing the shader (which is the costly thing). In the same way each instance has it’s own transformation, it can have other custom parameters passed to the shader. Actually this is something pretty common… For example to change texture array index, shift uvs, change tiling… I’m digging into UE for a couple of months now, and can’t believe this stuff is not there…
