anim Posted January 8, 2014 Share Posted January 8, 2014 not sure about HDK, but if you are looking just for that functionality then Find Attribute Value VOP or findattribval() VEX function is what you need it will return pt number of the point(or other element) from given geometry with given int/string attribute value or -1 if not found you can then use that pt number to import any attribute from that matching point http://www.sidefx.com/docs/houdini13.0/vex/functions/findattribval it's available since 12.5.192 Quote Link to comment Share on other sites More sharing options...
Guest mantragora Posted January 10, 2014 Share Posted January 10, 2014 Do you have any starting code? I'm asking because you are the second person here, with a total post count = 1, that signs to odforce and the first thing you are doing is asking about HDK stuff that from my experience is not something that people new to this forum should start from. There is a chance that you have ton of Houdini experience we don't know of but I would prefer at least some sign from your side that you really know what you are talking/asking about.
