nice
Model information :
Cryengine,unreal, and unity texture in texture.rar are packed texture for reducing memories in game engine ( see allegorithmic documentation for how to use it), if you confuse how to use them, just use the pbr base (metal) texture in texture.rar file/folder
you can ask me for product support if you have issue with model, some texture change, question, or anything
TIP :
The model may appear more shiny in some render engine, tweak the roughness map for fix it. For best result (like in the image) set roughness to noncolourdata /uncheck Srgb in your render engine or increase the roughness by multiply it by 1,5 to 2
