I was in charge to do this Door for the Califa Palace, I created this variation of the initial door, the first step was to reajust the size, correct the UV problem, after that it was to modelize the ornements you can see on the top of the doorFrame and on the 3 parts of the door.
Applied textures (Mesh decals and Trimsheet), Do a second time vertex painting to add dusty details, do the weighted normals and redo the collision and the guidances.
