Hello folks.

I'm trying to model a simple procedural cliff in houdini which its shape follows a curve. I do the curve, transforms it, skin it, covert it to polygon, subdivide it and then I apply a point vop to add noises and make it look like a cliff.

The process is fine until this point, but the thing is, I'd like a way of ‘distort’ my noise to follow the shape of my mesh. I mean, my current noise is based on @P, so it's projected uniformly, globally, so it doesn't matter if I move my curve, the noise will be applied in the same way. I want to move a point of my curve up and then the noise on this point would also be projected up, like in the img attached (left is my current mesh, right is the result I'd like to have).

thanks ^^

This is because your points are moving, so the noise samples at a new position when you move them around. If you want your noise to “stick” to the surface when you move it around, you need a value on your points that doesn't change when you move them.
Rather than using @P, you could use UVs or a rest position.
