I have a series of boxes setup in Houdini that I want to render, they were just polygons at first but when I rendered them, Mantra was smoothing the normals and it looked fairly bad (original.jpg). I then added a Vertex sop and turned on Cusp Normal, this gave me the look that I want to achieve (polygon_wCuspNormal.jpg).
Unfortunately I can not use polygons because I need to fracture these boxes and I need more subdivisions to do that. Switching to polygon mesh and increasing the subdivisions causes the normals to mess up again (polygonMesh_wCuspNormal.jpg). Does anyone have any ideas how to fix this?

Hi,
See attached for some options using the facet SOP. If you use the vertex sop and displacement in your shader you should look at this example. http://web.me.com/circusmonkey/circusmonkey/Shops.html [web.me.com]
