Col-Erase style Pencil Brushes

[NicoToonZ]

I've been wanting to make a pencil brush that simulates the Col-Erase pencils, yet with little to no luck. How do I get the brushes to look like them if I don't have the proper knowledge of making a proper brush for TVPaint?

not the look perhaps... but the idea of how col-erase pencils work is nicely embodied in the sketchpanel. (a custompanel that is part of the default configuration)

Well is there a special script I can use/make that can do the job?
