How to blend 2 materials with alpha map?

Hi guys, so I’ve managed to blend 2 materials together using a matlayerblend_standard, and I’m wondering if there’s anyway of using an alpha map to break up the blend in a bit of a noisy fashion? or even reduce the blend of the top material by maybe 50%?

Essentially I have 2 stone materials, one base and one cracked one, I want the cracks a little less prominent and more sporadic, here’s an image:

Thanks in advance!

You can use linear interpolate(lerp);

You can use linear interpolate;

before plugging alpha into matlayer blend multiply it with world aligned texture to get noise and breakup

Thanks, I think this worked! it’s definitely made the blend look less sharp.
