Polyextrude does not preserve point groups

Hello,

PolyExtrude does not seem to preserve point groups on the extruded points after extrusion, is this expected behavior? Prim groups however are preserved as expected after extrusion.

Is there a simple work around for this?

And it looks like doing an inset of any value sets all the point groups to 0. That seems quite unexpected

Hi,

yes it is unexpected.

A simple workaround might be converting your group to an integer attribute.

Edge groups are lost too.
I'm afraid Aizatulin workaround is not possible with edges, isn't it?

Not this way, but you can store the point number id for example, which gets duplicated and after this you can recreate the edge group, if the pair of ids of two neighbours correspond to a point pair of an edge within the group.
