hi,

i have some points with a name attribute.
i want to create groups with the group-name from this name-attribute, but the group node doesnt accept @name as the group-name.
does somebody know how to achieve this?
(i need these group-names for better selection points on the rivet obj node...)

Wouldn't that just be a one-liner inside a point wrangle? (assuming name is actually on points and not prims)
setpointgroup(0, s@name, @ptnum, 1, "set");

You could also use groups from name sop. If I understand correctly what you want.

thx a lot for the hints...

@Enivob, this works perfect, thx for the snippet (had to rename the name-attribute since it contained a namespace-character ":" and it seems group-names dont like ":")

@sepu, the "groups from name" sop doesnt exist in 19.0.xx, seems only be available in 19.5.xx, but this also works perfect in 19.5.xx, the renaming of the namespace-character is then automatically...thx
