Mesh Bump Problem

[Gerrard_Hickson]

Hi all.

I’m trying to adapt a grasshopper file (LINK HERE) for an application I’m working on, but I have hit a problem.

The file uses perlin noise to create a weight map, then it uses mesh bump to displace the mesh. The problem is that I need it to anchor the edges of the mesh - or rather, displace the mesh relative to the edges. Instead, it displaces the whole mesh.

It seems that my edges need to be displaced some amount between the min and max values, but it’s not clear what the value is. Furthermore, since the mesh displaces normal to the original mesh, I can’t simply rely on shifting along an axis.

Any suggestions?

Hello
Not on my pc now but it seems you used my plugin Nautilus and some of the noise librairie I use have outputs between -1 to 1.
My bump component also remap data so it could be better you use deconstruct mesh and using yoir own bump. You will have a better control

With the clarity of a good night sleep, I realised I was modifying the mesh at the wrong location… I should have done it after your graph, before the bump mesh.
