Hi,

I'm trying to find a way to remove all those islands from the group, that have, lets say, less than 4 or 5 connections.
So that only the bottom of this wall is selected. How can I do that procedurally?
I tried with connectivity sop, but don't know how to proceed further.
(I want to give all prims in the group an attribute, which I can then later use in Shading to only affect the bottom)

Thanks in advance

Have you tried with the Labs hda, delete small parts?

thanks, seemed a bit like a workaround, but it worked.
Had to use two of them with a fuse in between.
Than I was able to transfer my attribute back to the original geo.
