I have figured it out! Your custom vehicle plug in parameters for interior BLOCK this plug in. You cannot set them both. I had to use the originnal vehicle slots instead of a custom vehicle. I turned off custom vehicle and the interior map worked right away. So the custom vehicle plug in actually interferes with this one. I will just use this one because I don't really need custom vehicles right now I need the interior map more. but thank you for your time.

I am glad you got it working 😁
However I am not quite sure I am following... did you set up a custom ship vehicle in [CGMZ] Custom Vehicles? Or were you trying to make a custom vehicle with the id "ship"? Custom vehicles should only be used for custom vehicles, not for the default vehicles, and you should stay away from the ids "boat" "ship" and "airship" for your custom vehicles. Likewise, this plugin should only be used to add interiors to the 3 default vehicles.
