Viking chest

Imagine how people did produce planks before they knew sawmills. Sawmills were well-known in the ancient world. In the Roman Empire there were even ones designed to cut huge blocks of stone. But to the barbaric world this technology was unknown. The earliest evidence of an existing sawmill in central or northern Europe dates back to 13th century on the terrain of Germany. During the viking age the carpenters had to split the wooden logs with hammers and wedges. Then the rough and jagged surface was smoothed with a chisel or an adze. This technique left crevices similar to those we can see on carved wood.
It took a bit of work to reconstruct a proper material in Blender that looks naturally. I had to model the high-poly mesh of carved wood, make it seamless, bake the bump and AO maps on a plane, then I could blend it with PBR wood textures.
The model of the chest is inspired by an accidental archaeological finding from Mastermyr. The hinges also refer to findings from 9 - 10th century.
