I use this project for look dev purposes, render tests, light and shader dev. Hope you'll find it useful for your job or hobby. Main asset is multi tile uv geometry with set of appropriate textures, including 2 versions of deffuse textures. All textures are tiled .exr and .tx formats.
Also I must make a note on the HDRI I've used. I took it from great site 'hdrihaven' where you can get various hdri's for free and contribute to the artist, if you like. HDRI is not included in the project.
