How to group by filter expression "$CR>" in Houdini 16.

Recommended Posts

Hi everyone, 

I'm following a Houdini 15 tutorial and i'm using Houdini 16. Seeings as the group node has been changed in H16 i'm having trouble getting the same results. The tutorial uses a paint node to highlight a section of geometry and then uses H15's group node to select the painted geo. It then makes that selection into points and enters the expression “$CR>.2” into the filter expression box. 
Does anyone know how to replicate this in H16 with the new group nodes? I've included a screen shot of the tutorial for reference. Any help is really appreciated.

Got an answer from another forum. Figured I'd leave the solution here for anyone else needing the work around.

I needed to paint the geometry.
Then add a Group node and a GroupExpression node. Set both to points.
Then use the VEXpression “@Cd.r > .2”.

Got me the results I needed!

 hi Chris,  you don't need both of those SOPS,  having just the groupexpression by itself will do.
