Textures and UV mapping info:

High resolution textures made for physically based rendering (PBR) shader system exported out of Substance Painter(7.1.1) as such required texture maps as:

• Albedo,NormalMap(OpenGL and DirectX),Roughness,Metalness,Ambient Occlusion,Opacity(for alpha reticle in scope) .png/8bit (normal - 16bit)
• Unreal Engine(BaseColor, OcclusionRougnessMetall, Normal) .png/8bit
• Unity(AlbedoTransparency, MetallicSmoothness, Normal) .png/8bit

Model unwrapping made on only 2 texture atlases.For better use of UV space, some inconspicuous parts that are on the other side, repeated small details have been unwrapped by overlapping.Also Scale of inner unnoticeable parts decreased in UV space.That does not affect the quality of the textures and the general appearance of the model.

• M4A1_1 - 4096x4096
• M4A1_2 - 4096x4096
• Lense_Reticle - 256x256

After importing the model and the textures into the target engine you have to follow the official engine documentation on how to set the material up!
