there's two things I don't understand about the copyToPoints SOP.
1. transform using target point orientations - the tooltip explains that the ‘rot’ point attribute can be used to rotate copies. this does not look to be working as intended.
2. copyToPoints defaults to ‘z up’ behavior if transforming using target point orientation normals. this is not ideal if working in y up and scattering objects, it adds another corrective rotation that I need to keep track of.
ive attached a simple scene to show this behavior. any insight into these two things would be appreciated
Thanks!

Fixed the USD ROP in Houdini Indie/Apprentice to allow it to save out USDNC/USDLC files that compose in existing USD files from disk (rather than only being able to compose in other USDNC/USDLC files).
Does this mean that to USD will need to be authored first within another software package in order for it to be used in both other packages and houdini? And is it possible for USDNC/USDLC to be able to save out in ascii format?

ah. that would explain it. turns out I was the one that was outdated! I'm running 16.5 still, and was unaware that these were added recently.

Thanks for the response! i wasn't aware of maya commandPort but it looks like this might do the trick. I'll try using it and let you know how it goes.

I see button options to sync and reload, are these calling the callback methods? preSyncCallback and postSyncCallback do not exist when using listAttributes() on the HDA node so i'm inclined to believe the docs are just outdated.

I'm attempting to drive some python code in Maya on an HDA cook. The preSyncCallback and postSyncCallback look like they would do what i want them to do but i'm not having any luck actually accessing these callbacks. Does anyone have a working example of using these callbacks?

The Houdini node in Maya doesn't seem to have these attributes. How exactly does this work? i'm looking to attach Maya events to changes made by the HDA. will this get me what i need?
