Grasshopper render animation with VrayToon

I am trying to render grasshopper animation with Toon materials.

What I want to do is to have all geometries with vray toon material as base material, while having different colors defined by GH definition.

Using RenderAnimation component from http://www.giuliopiacentino.com/grasshopper-tools/, I could do all of above except for the Toon material part.

I have found a post regarding same matter ( http://www.grasshopper3d.com/forum/topics/how-to-add-materials-to-m... ), but since I am not very familiar with scripts, this is what I think his definition does. Correct me if I am wrong.

Since Rhino Vray only supports Toon environment per material (unlike Max Vray has global override feature),

1. import toon material from Rhino material editor

2. add colors to the toon material and make new toon materials with color (as many as needed)

3. import that new materials back into grasshopper

4. match them with designated geometries and render. (RenderAnimation component by Giulio does this job)

Here is the final work he did : http://vimeo.com/34728433

I am using rhino 4 with vray 1.5.

I have uploaded my definition, simple definition that transforms box height along with color as frame advances. The definition works but toon effect is not there.
