i did a global material with every settings i need, but i have a problem, i can multiply the global size of a texture coordinate, but can’t access U and V size separatly, btw i want to add a parameter to set the UV Channel in my material too.
is there a way to do that ? the coordinates node have not input for that.
Actually i have to create severals master materials with differents U and V size and its a pain.
An another question, i try to optimize my scene and i wonder if there is a different performance impact by using simple or complex material.
I mean, if i create a Master material with a lot of parameters (wich i can disable if i dont need it), is it slower to compute for UE4 than a simple material ?
