I have a curved glass wall made from simple panes of glass in RailClone. When I render in VRay, the reflections are faceted. I have tried many things to resolve this. Making very high poly versions of the base geometry, increasing the interpolation on the base spline. I've tried different materials, a vertex weld modifier, a smooth modifier, a normal modifier. None of it works. If I manually create the wall without RailClone then its fine. Is there a setting I'm missing somewhere?
