Update - 4 Dec 2020
I'm working on a new, more dynamic Graff style. I hope you enjoy.
Also, I'm not really happy with how the moss looks so I tried Substance Alchemist and found it really useful...Now I have to try them on the kombi.
Little update, I tried to give an oldest rubber aspect to the tyres.
Not really useful in this case because you can't see it, just a try to find a way to break the reflection .. Done with different gradients on the height channels, and I think it works pretty well ;-) it's a viewport screenshot.
Here is my last entry. It was really interesting to do. I hope you will like it.
