Package contains one handpainted wooden log which is saved in two formats. First one is standard FBX file, second is Unity package so you can simply import it into game engine.
Note that there is no metalic or roughness map so just set these parameters to 0 and 1 respectively.Textures folder contains normal map and color but also ambient occlusion so you can easly set up your material in game engine. Texture size is 1024x1024. Feel free to scale these down.
