Houdini Undo or Convert HDA HIP to neutral TXT format and back 3D model

cgtrader

DescriptionDescription Back story: Sometimes in projects I encountered creating an HDA which I really didn't want in the end. I then had to re-create the HDA contents in a new subnetwork. This tool potentially fixes that. Also saving by accident a scene that had a HDA imported with a lower license meant that the scene had to be redone or reverted to an older version. This also fixes that since you can export to txt and re-import that txt back in a different instance of Houdini. (The exported txt file is 100% python.) This tool: Exports selected HDAs, all HDAs or all nodes (the HIP file) to a .txt file Converts selected HDAs or all HDAs to subnetworks Imports txt files to your scene to a .txt file with an option to automatically re-create the HDA again on import The import-> convert to HDA is tied to your Houdini license, so if you're in a limited/non-commerical instance of Houdini in which you're importing, it'll create either a hdanc or hdalc. Content : 1 HDA that can be installed in any Houdini scene. Tested on Houdini 19.5 on both Windows and Linux. Workflow: Install/create HDA_ConvertHDA in your scene Set mode and parameters Make selection if applicable, select (with shift) the convert HDA as the last one so you see the parameter interface again Press 'Go' Parameters - Export: ExportSelected(HDAs only) - Exports the HDAs from your selection to txt (except HDA_ConvertHDA) ExportHDAsInScene - Exports all HDAs in your scene to txt (except HDA_ConvertHDA) ExportEntireScene - Exports all nodes in your scene to txt (except HDA_ConvertHDA) folderExportTxt - the folder where the txt files are written to. The filename of the txt file is either based on the source HDA, parent geometry and/or scene name, depending on which node you're in. Parameters - Convert (to subnet): (for HDAs with more then 4 inputs, use export/import txt or redesign it so it only uses 4) Basically an undo for HDAs, it converts it to subnetworks . ConvertSelectedHDAs - Converts the HDAs from your selection to subnetworks ConvertHDAsInScene - Converts the HDAs in your scene to subnetworks ConvertHDAsInFolder - Converts all HDAs in this folder to subnetworks (Toggle) KeepHDA - keeps the hda and creates a subnetwork next to it Parameters - Import ImportOneTXT - imports the txt file from the parameter 'FileToDo' ImportTXTsInFolder - imports the txt files from the parameter 'FolderToDo' - ConvertTXTtoHDA - after importing the txt file, converts the subnetworks (based on suffix _ConvertMeBackToHDA to HDAs Known bugs/issues Limited support for HDAs outside of SOPS, this is work in progress Still testing out HDAs to make sure they convert OK houdinihdahdalchdanchiphiplchipncdigitalassetscriptspluginsscripts pluginsmodelling
