Photo-sampled PBR textures. Import the FBX version for texture files. Download the Additional Files section for the SBSAR for use in Substance Painter and the Substance Plugins in whatever software you are using. VERY CONVENIENT using the Substance for Unreal Plugin

4k Textures Fully PBR (Metallic/Rough)
