ActiveValue Houdini points in fracture expression HELP

#1

Hey guys, I am new to Houdini and trying to do a project where I have a packed fractured object and I am making points in the center of these pieces to make a group as to what is active and not active using an expression in the ActiveValue DOP node. If you awesome guys could take a look at this expression and let me know what I am doing wrong.
Note: This is for packed primitives, so H13, not H12.

This is the expression
point("/obj/Angel/AC", groupbyvals("/obj/Angel/AC", D_POINT, “name”, $OBJNAME), “ACTIVE”, 0)

I think it’s the $OBJNAME part. Because when I type a string value, “piece0” it works. but i need it to look at all the pieces like “piece0-240” but that doesn’t work.

I would upload the file but it won’t let me so I have to do pictures

Thanks guys for any feedback at all!! :smiley:

i think if you need fast and smart solution please post your problem at:
odforce.net
or at sidefx forum:
https://www.sidefx.com/index.php?option=com_forum&Itemid=172&

it’s also good to post with a hip file where you can show your problem…

Odforce is definitely the best Houdini forum. Though I would like to liven up this place a little and give more exposure to Houdini on this site.

I already did on BOTH of those but no one responded :(. And I couldn’t figure out how to post the hip file on here. It wouldn’t let me the only options are images, or zip, and the zip file can only be like 95 kb. Thanks though guys for responding at least!
