Diagonal Bias In Distortion Shader?

[Megalogue1]

I’m still very much a beginner with shader graph. There’s probably a very simple explanation for what I’m seeing here, but I honestly don’t know how to put it into a Google-able question. So here I am.

I want to create a simple rippling circle. As in, just a plain, flat, filled circle texture with rippling edges. By referencing a Gabriel Aguilar Prod tutorial, I was able to make the graph in the first image below. But for some reason, it has a visible diagonal biased when applied to my circle texture.

As you can see, the top left and bottom right of the circle are much less distorted than the top right and bottom left. This is even more obvious when I crank up the distortion amount property. But when applied to a random texture from elsewhere in my project, the distortion looks pretty uniform. The second image below shows this comparison.

I want the circle to ripple uniformly, not with this diagonal bias. What am I doing wrong?

The reason most likely is that you have only single distortion chanell for both axis. Gradient noise outputs single float value, and if you displace both X and Y by the same value, the displacement is on top-right to bottom-left axis.
Try to create two noises with different offsets and combine them into vector2 before lerp node.

That worked great, thanks!
