After MVP is released, we will improve and make digital collectibles and accessories built as 3D models in UNITY to deliver quality-focused and high-end avatars. Their mesh and rig are stored off-chain to ensure scalability and low gas fees. Lower quality rendered images of the avatars/accessories are stored on IPFS to optimize storage costs.
The digital collectibles' metadata are stored on-chain. The 3D NFTs can be used in the game which is developed in UNITY.
