You don't actually need that image to solve the problem. All you need is to know the distance the pixel is from the center of the image. Here is a simple project built off the Noise Textures built in example:
drive.google.com/file/d/1A1jzWoIMUB5N3A0cF1GmfRzEnMWsHHn9/view
Notice the event the sets the pixel:
-> System: Set NoiseValue to (AdvancedRandom.Classic2d(XIndex, YIndex)
- (distance(XIndex, YIndex, LayoutWidth ÷ 2, LayoutHeight ÷ 2) ÷ 400))
× 100
I am subtracting the distance from the center:
distance(XIndex, YIndex, LayoutWidth ÷ 2, LayoutHeight ÷ 2
divided by 400 which is the max distance of an edge to the center in this example:
(distance(XIndex, YIndex, LayoutWidth ÷ 2, LayoutHeight ÷ 2) ÷ 400))
It's super simple but kind of math heavy. Hopefully it helps though. Good luck with your project.
