it's not a shader it is just alpha maped mesh.

As the gras models of the waving grass shader are alpha mapped meshes!

I don't think, that it is JUST an alpha mapped mesh, it is too. But the huge number of them - as is not in NOLF - I guess (I don't remember where it has been used there) - is placed and animated with a shader.
I think, it is not a fur shader, I think it is more a shader like the waving grass shader. Placed at the model by a second skin with points for the hair's places and length and "verticalness". Instead of meshdeforming (as it is in the waving grass shader) it get's a sort of gravity computing the relationship of the poligons normal, the z axis and the movement/force of the poligon.

This is only an idea, I don't know at all wether this is true or not.

What do you think?

And has someone any idea how to programm this!
