How can I add the secondary greyed-out text in the Object Manager?

[ymoon]

How can I add the secondary greyed-out text that appears next to an object's name in the Object Manager, like in the Condition (angular velocity.x) example? I'm not referring to renaming the object, but the system-generated secondary label. How is this done? I couldn’t find any reference to this feature anywhere.

Hey you need to react to MSG_GETCUSTOM_NAME_ADDITION and return a dict with the expected string with the "res" key.

You need to register your object with c4d.OBJECT_CUSTOM_NAME_ADDITION to have the additional name displayed in the Object Manager.

Cheers,
