extra_1 issues

[Izick]

Hi all, would anyone know why this is happening when I toggle extra_1 in the hierarchy?

Here is the hierarchy

The emissive part of the bar toggling on and off is correct, but the parts of the car toggling with it is not. Any ideas on what could be causing this?

I reinstalled ZModeler and that seemed to fix it. Odd, but I guess that's a fix?

probably other parts got the same identification number as the extra_1. avoid using your own part names, prefer using original part names only. if you need more geometry objects to be combined on one part, use "Group" button on Structure panel.
