Imported a CAD model from GrabCAD, then in Fusion 360, I applied materials to facilitate UV mapping and texturing.
After the export from Fusion 360 I imported the model into blender and used the UV seams from the exported CAD model with some manual adjustments where needed.
I made materials in Substance Painter and a leather material in Substance Designer which I made tileable in Substance Painter.
I made the lens material in Substance Painter and that's also where I added the text and decals.
