I was wondering if it was possible colour a paint effects brush,
based on the colour mapping from the paintable surface.


for example:

I want to have a field of grass whos colour varies across the field.

So I have got a nurbs plane onto which I have painted some grass.

It would be great to be able to paint up the grass colour texture on the nurbs plane and have it govern the colour of the grass.


Any Ideas would be greatfully recieved
