For example, let's say you need to bring in a car into a scene, position it and open the driver door (which is closed in the original alembic). How would you go about doing this?
All parts of the car's door resides in a specific transform within the alembic. If I could access this transform and place its pivot properly (unless already placed properly) I could then rotate it to make it open. How can I access this transform from e.g. an “edit” node or “transform” node?
I've checked the “Geometry spreadsheet” when having the alembic node selected and noted down the path to the transform in question. I've then tried to access it by defining the node's group as
@path=="/full/path/to/leftDoor"
@path=="*leftDoor"
How can this problem be solved?
Breaking the car up into pieces wouldn't work for me, unfortunately, as this is just one asset out of hundreds which require fine tuning when “imported” into Houdini.
Also, ideally I'd like to be able to update the car alembic (maintaining its internal hierarchy) so I don't want to add nodes into its hierarchy.
Cheers for any suggestions!
