I'm attempting to write out some transforms and geometry to maya from houdini as alembic files (and eventually vice versa)
The issue I'm having is that if I output the alembic with packed prims the transforms come through fine, but I get no attributes, conversely if I unpack the geo I get all the attributes, but no transform data.
In this case, it's not loads of data, just bounding boxes and transforms so I don't need to work with packed geo. But I'm pretty new with houdini so I'm having trouble figuring out how to get the data into maya in the required way.
Googling around it appears that it is also possible to append/set alembic user properties which comes through as a json dictionary on the maya side, which is a bit gross, but at least better than nothing, but again here I'm not familiar enough with houdini to know exactly how to create those properties pre -export.
