Unity Cloth - Facet No Smoothing, possible?

We are using unity cloth and the look we want to achieve is to have no smoothing over the triangles to give the faceted look. Is this possible? I've tried the usaual technique i use for meshes, remove smoothing groups in max, and import normal and tangent data in model settings, and used that mesh as the cloth mesh but it still smooths it. Is there a shader I can use, or a setting i have missed? Any help much appreciated!
