I want to present you the model of Old Pirate Chest. Textures are ready to use in Unity 5 Standard Shader. Max file includes HP and LP model, others files includes only LP model. I overdid with polygons on HP model (1kk polygons) :D So be careful to open max file :) Hp model haven't been Unwrapped. Render images are from Substance Painter render engine. There are 3 zip files with same textures but different file format of model.
