Now that Microvellum is working on applying Render Materials to Database Materials, I would like the face-up side of the material to show on the Nesting Optimization Report to help the machine operator ensure that the material is placed on the CNC with the correct side up. If the material is grained, the snapshot of the face-up Material/Texture Mapping should be oriented in the direction indicated in the material's information as to whether the grain runs the length or width of the sheet. These improvements would reduce re-work and material costs. 

If you are using Formula Driven Materials, the Rendered Material face would be based on the face of the laminate/veneer in the database.
