Easy Way of Remastering Decals

Description

Can't find good picture that you could use as texture? This is case with loads of old trucks I'm modeling. If truck still exists, decals have deteriorated beyond usable. Old many times copied photos are also too blurry to so any good. I can't use any vector software, so I do all this in Blender. Set rendering engine to Workbench, style as flat textured or flat material. Trace with single verticles over blurry pic and use subdivision surface modifier. Topology does not matter, whatever that gives results is good. Render out with ortographic camera at 1:1 aspect ratio. You have Substance Painter compatible decal there.
