Hi All,
I was wondering if someone could help me fix this material. I have a basic scrolling noise texture hooked up to a gradient mask. The aim being to have a sphere that distorts only slightly at the bottom but alot at the top.
However I notice that when I increase the intensity of the distortion the Texture Coords are affected and creates a diagonal band that the distortion seems to follow.
Can anyone explain why this happens and how to fix it? Would help me out alot! many thanks 
You can lower the value of the multiply attached to the texture sample, and I generally multiply with tex coordinates instead of adding.
If I multiply in my texcoords my texture disappears completely does that not happen to you?
Also if I just lower the multiply value then I don’t get nearly enough distortion on the texture.
It’s diagonal because you’re adding a value between 0 and 1, to U and V → It’s only ever going to get distorted in one direction.
Try using a normal map (Component Mask RG), then scale that down like you’re doing and add it to the TexCoord.
Also, if most of your pixels are a in light grey range (it seems that you don’t have that much black in your texture), then it’s a bit like you adding a small constant in both x and y and some noise on top of that.
Switching out to a normal map fixed it! thanks everyone, much appreciated, I also think I get what is happening now
