Procedural Plumbing (HVAC) Material

The three different materials are visible. This is the first time I have prepared a breakdown on how I created them. I would like to thank my friends who helped me create the materials and my mentor. I would also like to express my special thanks to Javier Perez and Fast Track Studios for their Marmoset Toolbag tutorials. Attached are the links to the ArtStation profiles of those who supported me.
