ron2812 Posted June 7, 2019 Share Posted June 7, 2019 Hey! Is it possible to pass an input of a OBJ-Level HDA into a subnet inside the HDA? This is what i need to do: (see screenshot) Inside the subnet i don't have access to the input directly. And since the null node is on OBJ level, it doesn't contain data from the input (input is only the parent) Thanks in advance! best Ron Quote Link to comment Share on other sites More sharing options...
vicvvsh Posted June 7, 2019 Share Posted June 7, 2019 Do you want to have geo information into a OBJ level hda? I don't know how it will be work in Unreal but in Houdini I would make path parameter on the hda and object merge SOP inside geometry OBJ node with relative references expression. See attached geo_to_hda.hipnc Quote Link to comment Share on other sites More sharing options...
LaidlawFX Posted June 7, 2019 Share Posted June 7, 2019 I believe the Object merge in your sopnet will give you the function you need. The geometry path should self propagate to the interface of houdini engine. No need for the object level input. (It used to work like that anyways) 1 Quote Link to comment Share on other sites More sharing options...
ron2812 Posted June 7, 2019 Author Share Posted June 7, 2019 Hey! Thanks for the replies! I got it working inside Houdini - but as it seems in UE4 i don't get any inputs on a OBJ-level HDA anyway :-( So i need to find a different solution. But thanks for the fast help!

AlexHogan Posted December 6, 2019 Share Posted December 6, 2019 So I have the same problem here - but my issue is that I need to get the Position of the OBJ level node that ths current HDA is contained within - if I connect it to itself with an Object_Merge it created an infinite loop and errors out!

AlexHogan Posted December 6, 2019 Share Posted December 6, 2019 It was so much simpler than I thought - ch("../../tx") Quote Link to comment Share on other sites More sharing options...
