thanks for playing :3

For black highlights:

I had actually convert line art to curve and then to mesh.

or 

You can even duplicate the edges of the mesh and seperate as selection.

when you convert to curve, you can add depth to that curve to make the outlines look broader (increasing curve radius)

Then delete the outlines you wish to remove from the view

I take it back. It works now and I must have beeen hitting quit which breaks it in webgl
