Hello there, this is my first post on the Unity forums so pardon my noob question. 
I am having trouble getting the toon shader, that comes with the Unity standard assets package, to work as desired. I am only posting this, as I have tried everywhere to find a working solution on the Unity forums for this to no avail.
When I add a toon shader to a scene object other than the standard objects (such as a cube, sphere etc…) the shader does not diffuse correctly and creates a bunch of polygons. What is the proper way to add a toon shader to an existing model and texture?
For example when I add a toon shader to this bush, it goes from this:
To this:
I need it to look like the first image but cell shaded. Any ideas? Thanks in advance
