🏠LOD0
The specifications below detail the file guidelines for creating 3D content for Upland's Super-App.
The LODs meshes are a simplified version of the NFT original one. We suggest to retopology your original design and project all the intricate details into the new mesh. We also recommend completing at first your LOD 0 before building any of 1 and 2 since you just can downgrade it to make it match the other LOD versions.
