That’s usually not the case. Most assets are entirely cosmetic. It’s why when things get messed up you tend to see purple floor, wireframes or checked test planes. As far as coffee is concerned art assets are usually just “what do I make this look like”. As far as physics and interactions goes it’ll do exactly what it was supposed to before. That’s not too say it’s not valuable, but whoever gets the code can by the pack, put in the right asset references in the right places in the code and be exactly where they were before.
