Having bought V-Ray Masterclass by Erasmus Brosdau at www.eat3d.com some adjustments were made to the rendering of this piece. The black fabric on the previous render made the whole images too dark and I finally mastered HRD lighting. Rendered in Vray, modelling in Solidworks and 3ds Max and post processed in Photoshop. Erasmus’ video tutorial is excellent and goes int much dept about mastering Vray. It wasn’t possible to cover everything about the program, but the areas which I was previously finding difficulty such as artifacts and render time are covered well.
