I just figured out the answer - I needed to disable "Optimize Cache" on the generator's Object tab.

I have a Python generator with a child object (in Object Manager).

When I move/scale/rotate the child object, the Python generator code does not run, and so the display becomes stale. I have to change the generator's User Data to get it to recalculate.

I tried using message() but that did not help, even for all mid's.

How can I make sure the generator code runs when its children have been edited?

Thanks for the great suggestions!

I just discovered I can also use "File | Save Object Preset" and "File | Load Object Preset" in the Attribute Manager.

I've written a Python Generator which uses 14 User Data items (located on the the generator object).

Is there a way to associate the User Data definition with my Python Generator script, such that whenever I create a new instance of this PyGen object, the associated User Data is automatically added to it?
