Based of the 2D concept piece "Mushroom Potion" by Ivan Kunakh (artstation.com/artwork/YarQYq), I modelled and shaded this using Maya and rendered using Arnold. This was my first time using Arnold's new toon shader and I'm really happy with what I've come up with. All texturing was done procedurally using the Hypershade editor in Maya with the exception of a mask defining the spots on top of the mushroom lid. The reason I did it this way was that I wanted to be able to change and control all parameters on the fly without having to jump into another program.
