⛄LOD1
The specifications below detail the file guidelines for creating 3D content for Upland's Super-App.
As mentioned before, LOD 1 holds the same structure as LOD 0. The only substantial difference would be the triangle limit per mesh,tags and the UV map texture size.

UV Maps
Do not leave unused areas
Avoid stretched images
If the model is symmetrical or has any repeated mesh or shape, these should be overlapped
Include a 10px bleed for the UV islands
Any UV island with flat colors/textures should be overlapped
Keep UV island size relatively scale according to the actual size of the area
Avoid any stretched or curved sections for cylindrical shapes UV map
