I was working on implementing a gradient texture with a noise texture, but only wanting the noise texture to effect a certain masked out area, I don't want noise texture effect in the top or bottom of from the border, I want them to be gradients, but just on that edge I want the noise/distortion effect, I have current node setup:

EDIT: I also want to be able to individually control the gradients, ie have two different colors if I wanted for the top and bottom half

  • $\begingroup$ in my opinion, you should accept the answer that is provided by Robin. Editing your question adding details is not fair at all (again: in my opinion). $\endgroup$

  • $\begingroup$ right I realized that I should have clarified in the beginning, I have upvoted the answer and I'm hoping hopefully if Robin see's it again he can modify and tell me how to achieve my desired effect, if there is no response by tomorrow I will accept his answer as this is pretty similar to what I wanted anyways :) $\endgroup$

As I understand your question, you want the Noise to be masked..

Here's one way. In this case, I found it easier to use Object-Space for the texture coordinates, putting 0 at the center without further adustment. But you could compensate, in some other space...

To conceal any boundary between the noise and the plain background the last stop in its mapping was drag-drop copied from the background color.

This shows mask, noise, and masked-noise :

  • $\begingroup$ Hey, thanks for responding, I want to be able to individually control the color for the top and bottom half of the gradient, in the shader you mentioned, I seem to only be able to control both, is there a way I can control them separately? $\endgroup$

    $\begingroup$ @NunMatters It's still actually tricky to figure out exactly what you need.. there are so many variations possible. Here's a start at a group that makes a noisy transition down Y between 2 colors, disguising the boundaries between pure color and noise-mix: blend-exchange.com/b/Or2YJv0X $\endgroup$
