List of Shaders:

1. Rusted Metal
2. Antique Metal
3. Cast Metal
4. Milky Metal
5. Galvanized Metal
6. Hammered Metal
7. Brushed Metal
8. Cloudy Ceramic
9. Condensation Glass
10. Speckled Ceramic
11. Spotted Ceramic
12. Gradient Ceramic
13. Leather
14. Marble
15. Cracked Ceramic
16. Granite Shards
17. Splotched Granite
18. Paint Blend
19. Wood
20. Mystery

All but two are EEVEE compatible. (Leather and Splotched Granite)

Each shader has many features. All of them have smudges, dirt, and scratches that can be turned on and off via slider. You can also turn on "random" to receive a random vector for each object. That way you never get the same texture. Or, you can turn it off if you need it to be the same, which I recommend for a few, like the brushed metal.
