Geometry – scenes with lots of objects and/or triangle counts require more memory to render.The following are recommendations from Chaos the developers of Vray, for reducing excessive memory usage in Vray for Rhino and Sketchup
Try at least rendering a lower resolution, and if you must then work your way higher. Often you can solve problems with render times and crashing jobs by being less pushy with your final images sizes. Troubleshooting Rendering / Memory Crashes
Override materials (see below): Global Switches. (Start low and work up if the image quality is not adequate) General – Preview / Very Low / Low / Medium etc Lower the quality of the final render there are some presets that can be loaded from the top of the Vray Options window:. Quick Render Speedup / Memory troubleshoot tips Consider adding people / foliage / rain / etc in Photoshopįor render sizes the following is a list of image resolutions that will fill A3/A2/A1 sizes: 
Similarly, thousands of trees with dense branches,etc are going to kill a render as each twig needs shadow calculations etc. Think about what you are rendering – turn off layers / objects that you won’t see there’s no point having complex hinges included in a distant perspective for example. While it is important to have good quality, sharp final images simply dragging all the sliders up to maximum quality is likely to have little visible difference but will significantly increase the time taken – and also the likelihood of the machine crashing altogether. Rendering, like printing, is one of those tasks that always takes far longer than you expect.

V-Ray for Grasshopper (included in V-Ray for Rhino) allows direct rendering of your parametric and generative designs as part of the Rhino scene - without needing to bake geometry. Tutorial 1: Getting started with V-Ray for Grasshopper Plus, to help you optimize your V-Ray for Rhino workflow, you’ll find another 5 videos to guide you through some of the best new features in the latest release.īe sure to follow along with a free 30-day trial of V-Ray Next for Rhino. We’ve compiled 5 tutorials from the Chaos Group experts to get you started with V-Ray for Grasshopper. V-Ray for Grasshopper comes with V-Ray for Rhino, which makes it quick and easy to animate and render your parametric designs. It also allows designers to deliver professional-quality renders every step of the way. V-Ray is a trusted 3D renderer that gives Rhino users the power to render everything, from quick concepts to finished designs. It’s an exciting way to explore parametric and generative designs in architecture - and the ability to create and render those concepts and animations to present to clients is considerably even more impressive.
