Hi all, thanks for posting and indeed we are going to explore metadata handling in general. Cheers Jana

Thank you for the reply. Good information.

@m_adam - Now I'm sorry for my late reply! I appreciate you writing this up for me and I think it's a really good reference. This question has been answered then! Another quick question which sort of relates (I can create a new thread if admins want) - Do you have any recommendation for up-to-date C4D Python API training? I'm coming from writing Python in Houdini and Maya, but Cinema 4D seems to have a more unique setup with how to interface with their API. Any training recommendations would be appreciated. Teach a man to fish and... something something fish. Thank you, Clayton

Very good. Thank you for the response and guiding me towards the appropriate channel of communication for this. Best, Clayton

@m_magalhaes - All good! Just wanted to make certain that the issue hasn't been fixed yet (since 2018..). In the future I'll write a python class, extending a group that is collapsible using the workaround you mentioned. Thank you for getting back to me and looking into this! Cheers.
