Package contains game-ready wooden barn which is saved in three formats. First one is standard FBX file, second OBJ and third is Unity package, so you can simply import it into game engine. Preview images were rendered in setup imitating game engine, so results are quite similar to those which you may achieve in game.
Key features:
Textures folder contains color, normal, roughness and occlusion texture, so you can easly set up your material in game engine (use 0 for metallic parameter of your material). Texture size is 2048x2048. Feel free to scale these down.
Most of preview images were rendered using higher quality mesh with smoothed edges. Comparison of both meshes is shown on last two images.
