Hi,

i have a node with some primitives and some primitive attributes named corner_1 to corner_N. the amount of corners is variable and depends on whether the endpoints overlap or not.

now i want that the primitiv is attached to a group called corner_X if the value in the corresponding attribute is 1

is that somehow possible?

greetings

Hi,

Why don't you do the grouping in that python SOP that is plugged
into the group node? If you're looking for a node based approach,
put the group SOP into a foreach SOP, loop N times over your primitives
and stamp the loop iteration onto the group name parameter, use the
stamp() expression in the group's expression field as well!

Best,

Manu

thank you, that worked fine

i thought i've read somewhere that it is not possible to create groups from within python code…

that was some previous version of houdini where grouping wasn't possible, with Houdini 12 you can definitely do it.
