As a part of a more complex scene including my amp cabinet, amp head and guitar, here is a test of shaders using Substance Painter for the Metalzone pedal.
The other pieces are all modelled and with basic shaders. I just need a good idea for the composition so comments are wellcome!!!
In the mean while I have been playing with Substance Painter and this is the result. Hope you like it!
