Good to know

About the packs

What is in a game asset pack?
A set of GLB models made as a group, sharing one scale, palette and level of detail, along with a starter scene that arranges them into something you can load immediately. Packs list their total file size and triangle count so you can judge the budget before downloading.
Can I use a pack in a commercial game?
Yes. Packs are CC0 1.0 Universal like everything else here, so commercial use, modification and redistribution are all allowed without attribution or a licence fee.
Do I have to download the whole pack?
No. Every member of a pack has its own permanent CDN URL, so you can take one prop or the entire set. The pack manifest at /api/v1/packs/{slug} lists each file with its URL and size.
Do the models in a pack fit together?
That is the point of a pack. Members are authored to one real-world scale with consistent pivots and a shared material style, so a building, a vehicle and a prop from the same pack sit correctly in one scene without rescaling.
