Game ready model, low poly can used as a game object or props object 

In .blend file low poly mesh already triangulated with all texture set up for scene and high poly mesh 

All texture in 2048x2048 (normal, ao, basecolor. metalness, roughness, emissive map) For unity same texture sets 2048x2048 (normal, ao, basecolor. metalness with roughness from alpha, emissive) 

Perfect working with Unreal and unity
