Hello;

I have an attribute called “name” (values are P0 to P8).
By using SOPs, how can I create a (one) group and fill it with that attribute values?



Thanks.

I'm not sure if I understood your last part of the question about “fill it with”, but if you want one group based on certain attributes, then you can add those in the Base Group parameter in the Group Create SOP:
@name=P0,P1,P2,P3,P4,P5,P6,P7,P8


If you want one group for each primitive with the same attribute and a matching group name, then you can do that in a one liner in a wrangle:
setprimgroup(0, s@name, @primnum, 1);
