3D Studio Max
Let us now look at the parts of armor. Here we will use 2 materials, a material for metal and another for the gilded metal parts as on the design.
Here we don't make a base texture, we will do it at the end once we have all the textured parts of armor.
Here we separate the UVs, avoid having to worry about the texture in Photoshop, take care not to paint between the various materials and colors.
