Do you have all your assets in a single .blend file for your game? Or do you have multiple .blend files, one per asset?
If you store all/most assets in a single .blend file, what blender features do you use to make sure you don’t accidentally alter an unrelated asset while making changes to one asset?
@Sibbo from what I can tell from observing the artists I work with it’s mostly a mixture of both, assets that somehow belong together tend to be in a .blend file together, separated by scene collections.
