BludArtworks 2 Posted January 16, 2018 (edited) Hello ! I’m completly lost with group syntax and wildcards. I try to combine every second primitive group. Looked at the doc (http://www.sidefx.com/docs/houdini/model/groups.html#syntax) but it doesn’t help me sadly. Any advice ? Thanks group_problem.hip Edited January 16, 2018 by BludArtworks Share this post Link to post Share on other sites
Sepu 259 Posted January 16, 2018 (edited) In your copy transform output copynum attrb pack your geo then you can use the the module function in a prim wrangle to get every 2 prim grp if(@copynum % 2 == 1){ i@group_newGrp = 1; } You could also use the group range as well.
