Bonnet Dummy Rotation 3DS Max

[Horwath]

Hello! I stopped modeling about 2 years ago, and now I’ve started again, but I’ve encountered a small problem.

I remember that back then it was possible to set the opening position of the hood, for example, in the following way: bonnet -> bonnet_dummy -> bonnet_ok. However, I can’t remember how to modify it to make it work. Thank you in advance for your help.

Example for The Hood opening state:
