Perhaps its just not a thing, but I personally like to set any and all my textures to shared wrap/clamp wherever possible.
Occasionally (well… rather often actually) I come across situations where I need to clamp or mirror either X or Y.
sadly there is no option for this in the material editor, so I need to set it trough the texture and am unable to use any of the “Shared:” features.
Is this something epic is willing to look into, or is it a limitation and I will have to
