Flakked Posted April 22, 2021 Share Posted April 22, 2021 (edited) Hiya, So, I have a simple HDA with an int parameter I created called weldSeamsID, and an imported Houdini Engine attrib called hemax_matid. What I'm trying to do is take that parameter, and reference it in a group SOP based on the hemax_matid attrib. Essentially, I want the Base Group to be: "@hemax_matid" EQUALS "whatever the weldSeamsID parameter is set to." I tried linking the two together via the drag and drop under the Channels tab in the HDA, but unfortunately I cannot add any extra code to that reference without it breaking. (As far as I can tell, at least.) Edited April 22, 2021 by Flakked solved Quote Link to comment Share on other sites More sharing options...
