Best SketchUp to V-Ray Rendering Tips

Rendering uses a program to simulate materials, lights, and shadows in a 3D model. The output image looks more like a photo than a 3D computer model. Rendered images are can more accurately represent the final build than the 3D model alone. SketchUp offers the ability to generate renders within the program in one step. It also offers real-time rendering, allowing you to move through a 3D model and view it as though it were completely rendered in real-time.

Creating a model for rendering does have its own set of rules. To get you up and rendering as quickly as possible, here are 5 tips for prepping your SketchUp model for V-Ray rendering.

1. Properly Orient Faces

SketchUp faces have a front and a backside (default material shows the front as white and the back as gray). Some renderers will render back faces invisible. Therefore, it is important to make sure that all faces have the correct orientation before you attempt to render. The Monochrome view type in SketchUp is a great way to see your entire model color-coded for proper orientation. 

2. Leverage the Rendering Engine’s Materials

While SketchUp materials will render OK in most rendering engines, you will get the best result by using the materials that the rendering package includes. Materials for rendering include attributes that SketchUp is not concerned with, like reflection, bump maps and luminescence. There’s no need to spend hours customizing a material in another program because the photoreal details are already baked-in into the render-ready materials. Simply plug-and-play with the V-Ray Rendering material library.

3. Pay attention to Lights and Camera

In SketchUp, there is one camera and one light. A rendering engine can handle any number of different lights and camera locations for a single model. Depending on the level of integration, you may be able to place these items into a SketchUp model while you are modeling, making it much quicker to generate final renders.

4. Clean It Up

Rendering a model is like having a photoshoot. You need to spend time prepping your model before the final output. It may be fine to have extra components or stray lines around your file while you are actively modeling, but only show what needs to be in the final image when it is time to render.

5. Pull-in Render-Ready Assets

Many renderers offer a slew of render-ready assets that you can drop into the model to make your render more realistic — from cars and trees, people and animals, to water and grass. These are things that can seriously weigh down a SketchUp model. But, render-ready assets can be added as low-poly proxies in SketchUp and then rendered as highly detailed assets in the rendering engine. With SketchUp, it is easy to choose your manner and type of rendering and has integrations with over two dozen different rendering engines. SketchUp also offers full access to V-Ray 5 with a SketchUp Studio Subscription. 

6. Faster rendering with GPU in Vray & Sketchup

As we all know, V-Ray offers two rendering engines including V-Ray and V-Ray GPU. GPU rendering allows V-Ray to perform the ray-tracing calculations on the GPU cards installed in the system, rather than the CPU. Since GPUs are specifically designed for massively parallel calculations, they can speed up the rendering process significantly by an order of magnitude. V-Ray GPU uses NVidia CUDA or RTX device(s) to perform the ray-tracing calculations. 

Not only rendering with single GPU card, V-Ray scales very well across multiple video cards.  It will not be a perfect “4 GPUs is 4x faster”, but you can expect significant performance improvements with every card you add.

iRender - Leverage the power of multi RTX 3090 to boost render performance

iRender is one of the render farms highly recommended for Vray rendering. We provide dedicated servers for almost all requirements of designers .
