Grouping clusters and Isolation to create more detail

[aliaq95]

Hi guys, 

So I have made a an overall form with sharp edges created in and around to what will be a spaceship/ procedural model. However, I can't seem to separate the group clusters separately to Poly extrude in their specific normals. 

 

Thanks! First time posting here!

something strange going on with the cluster integer attribute, normally a split node would do the job, but in this case I just did a very simple conversion to float in a vop and it started working as expected.

You can use Point Split SOP to split using the cluster attribute.

I'm just giving you some tips

Hey guys, thank you for all the solutions and tips, super inspired by Akira Saito's work so I definitely wanted to build something. Will be continuing this and keeping posted on the progression of this! PS Not really fluent in VEX. Also don't know how to individually reply but Appreciate this community here!

edgecusp seems simpler and alittle bit more efficient,i post it here although the problem might have been solved

Can you elaborate this please?

If you have a prim attribute, you can use it to split the geo into separate pieces like this:

Aha thank you, then I misunderstood what the point split does, its purpose is to create clusters then?
In Akira Saito's presentation at 31:02 min. he is using the now depricated vertex split. (in the documentation it says we should use the point split instead, as you did).

It seems to however be used to dissolve some vertices instead, maybe I am misunderstanding the footage.

Which ties into a question @Caskal once asked.

That's basically what I am trying to find out

It's hard to see what he is doing from looking at that part, but if you want to split the geometry at arbitrary places by adding new detail along those edges across the faces, then I recommend this approach:
