If you don’t mind, could you try something more for me, please?
I know we have seen similar issues of creating directory on Nucleus in Houdini, and we are working closely with SideFX to sort out the issues. I have tested similar steps on my end and the USD ROP created the directories and wrote out the files correctly. I am happy to help if you are still experiencing the issues. Please give the suggestions above a try and let me know if that works for you. The “q” will quit Houdini before writing out any data. The other issue I notice is the Pre-Render Script.
The other way is to change the “Save Style” to “Flatten Stage” on the USD ROP if you don’t need to preserve references and sublayers. You can also config where to save the layer by using a Configure Layer () LOP. There are several ways to get around this issue, easiest one is uncheck the toggle like I suggested above. You will usually only turn this off if you are using the Save style “Separate layers” to write out every layer separate for debugging purposes. When this is on (the default), the node errors if it would otherwise write an anonymous in-memory layer (that is, a layer with no file path metadata) to disk. Error Saving Layers With Implicit Paths.The first option is a feature that Houdini has specifically, and that’s why you don’t see it in Maya.
