I am a beginner in Unreal Engine 4 and I also have that kind of probleme. I use a noise texture in alpha input for the “linear interpolate”. I put a vector parameters on each input A and B of the node.
But, when I move my object with my materials apply on it, the noise is always moving, wich can be annoying for an animation character with this materials. I also can’t apply a texture on it, a noise texture because the materials will appears on one parts of the characters but not on the others parts. I have unvrap my charachter on an external programme so I don’t enderstand the probleme.
Can you help me ?
