Fracture Material UV tiling

So we’ve set up some destructible objects and I’ve applied a fracture material to them. The fracture material rollout has a UV Scale parameter. However, no matter what value I set these to, the material is displayed the same way on the fractured surfaces. By default it tiles too many times, so I’d like to get this sorted out but I haven’t found any hint of this issue in the documentation or forums or anything. Any advice would be appreciated.
