Keep Default Dimensions When Overriding 3D Model Settings

When overriding a game’s default 3D model settings, there should be an option to keep the platform’s default case dimensions.

Right now, if I only want to change something small, like the spine or cover background color, LaunchBox stops using the default case dimensions and resizes the model based on the image unless I manually enter custom dimensions. For platforms like Sega Genesis, that means extra guesswork just to preserve the correct case shape.

A “Keep default dimensions” option would make it much easier to customize small visual details without having to manually recreate the platform’s default measurements.
