Changing uv tiling/stretching via particle data.

[shadowkiller]

Update: If i use the tube mesh mode i can get close to the mapping i am going for. The problem is i would like to use an existing 2d mesh that already has some modifiers applied. Using a mesh also gives me more control over the amount of verts in the total ribbon. 

Is there a way to achieve this the result using the mesh option in the spline mesher instead of the tube option? The tube option is adjusting the mapping based on the distance between the knots but i didnt see any way to tie that in to the particle system.

Thanks!
