chrissweeny Posted September 5, 2017 Share Posted September 5, 2017 (edited) 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.

chrissweeny Posted September 5, 2017 Author Share Posted September 5, 2017 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! Quote Link to comment Share on other sites More sharing options...

toadstorm Posted September 13, 2018 Share Posted September 13, 2018 many SOPs are switching to VEX snippet-style syntax for ad-hoc group masking and parameter expressions. local variables like $TX $TY etc still exist, but they are only compatible on a SOP-by-SOP basis, and they don't support arbitrary attributes like @myAttr<3, so my advice would be to start using the VEX syntax wherever you can.
