🗿LOD2
The specifications below detail the file guidelines for creating 3D content for Upland's Super-App.
As mentioned before, LOD 2 holds the same structure as LOD 0. The only substantial difference would be the triangles limit per mesh,tags and the UV map texture size.

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
