This is a re-generated model :
- I went back and captured the front a little more so now it's clean
- i cleaned the mesh using Blender
- I reduced the diffuse to 2K and roughness to 1k
- I removed normal and AO
- I changed metalness from 0 to 1
the result is a great AR-ready model that is about the same size as a picture : 4.9MB
