3D model path relative to project

Is there a way to set the path to the 3D model of the footprint relative to project location?

How can I append a path to an environmental variable used by kicad?

use “KIPRJMOD” as environment variable…
This var is pointing to project folder path
Here you can find a project fully portable with 3D models placed in a relative path folder

In Preferences->Configure Paths you can add and define whatever environment vars you want.

I tried that before and it didn’t work, but tried again and now works. It seems that I was expanding the environmental variable in a wrong way (using () instead of {}).

Thanks!.
