Not Meant to be 100% accurate seeing as there are only like 2 somewhat decent images I have found. Traveler's Shield from upcoming Legend of Zelda Breath of the Wild, my first time using zbrush and gimp, Make sure you view in HD, textures 4k
Workflow: Blender->Zbrush->Gimp->Substance Painter 2
EDIT (5/30/17): Went back and retextured the wood, now downloadable but this was made with a trial version of zbrush and a student version of Substance Painter so keep that in mind if you try to use this
