V-RAY is a computer-generated render plug-in for 3D computer graphics software (3Ds Max, Revit, Rhinoceros, SketchUp, & more). This application is used for video game production, industrial design, product design, architecture, and the interior design industry. Show
Chaos Group developed V-RAY in 1997. This rendering engine uses Global Illumination algorithms, including path tracing, photon mapping, irradiance maps, and directly computed global illumination. Watch these Quick Start Tutorials from ChaosTV. For additional resources, please refer to the V-Ray for SketchUp Courseware site. Rendering ExamplesV-RAY trial installation for one monthYou may be able to download and use the trial version for one month after you purchase the trial version via the Chaosgroup website.

Render setting for a REALTIME V-RAY RENDER – a preview modeHow do we prepare your SketchUp model for a V-RAY rendering? It depends on your process of work. For example, if you directly build all of the models in the SketchUp file and apply the materials while modeling, you can use the V-RAY at any time, even at the beginning of the modeling. Using a completed Revit model for better rendering results, you can use V-RAY after building all of the models and then applying materials and lighting through V-RAY. This tutorial will demonstrate how you create a rendering based on the Eames House 3D model from the Revit model. I only added SketchUp Glass on the model. In the previous lecture, I showed how to import the Revit model to the SketchUp model and apply the SketchUp material. Please refer to the previous lecture for the information.

(CO3) Understand Vray material settingsV-Ray provides many advanced settings for realistic and artistic renderings. There are at least three ways to apply V-Ray material. Tip 1. Material name properly. For example, 001-GL-EX-01, 001-CPT-RED-01, or 002-WD-DARK-FUR-01 For more information, refer to this Materials in V-Ray tutorial. [METHOD 1] Use a SketchUp material and update V-Ray material propertiesThis way is helpful if you know how to add/edit the material properties. Suppose your SketchUp model already has the SketchUp materials that you want to use for your project. In that case, you can update the material in Asset Editor by editing Reflection, Refraction, Bump, Displacement, and more.
[METHOD 2] Select an object with a SketchUp material and replace it with a V-Ray material from the libraryThis method is helpful if you don’t have any knowledge to edit the material properties. You can use this method if your SketchUp model has a material already applied and you want to reply with V-Ray material from the library.
[METHOD 3] Start from scratchIf your SketchUp model does not have SketchUp material to start, you can use this method. (CO4) Understand Vray lighting settingsSet sun and skyBefore we work on artificial lightings, understanding sun orientation and adjusting the sky is necessary. V-Ray recognizes SketchUp Sun orientation. To see the current building orientation and sun relation setting, open the [Shadow Setting] panel and check [Show/hide Shadow] to see the direction of the sun is suitable for your rendering. If you want to change the sun’s direction, you may change the building orientation, time zoon, time, and date. In Asset Editor, you can control the Sun settings. For example, you can change the Sky model, change the color of the sky, the intensity of the sun, the density of ozone, and more. Self-illuminated materials – Lighting sourceTo express self-illuminated material like a lighting source or lighting shade, you can add [Emissive] on a V-Ray material. Add V-Ray lighting source – Rectangular for windowsThis tip is a trick of V-Ray rendering. Adjusting the intensity of the Sun on V-Ray is not enough to illuminate the interior space. V-Ray users add Rectangular lighting sources on windows to make the space brighter and better render results. This may minimize the noise effects on the render results. Tip. You can use a [Plane light] for a rectangular shape lighting surface. You can use [Sphere light] for the round surface/spherical shape of an object. Add V-Ray lighting source – IES lightingV-Ray lights support a .ies file which contains the lighting profile/footprint for a light. If you use IES lighting in V-Ray, your rendering will look more realistic. (CO5) Understand the Final render and save the imageFinal render settingOnce your SketchUp model, materials, and lights are ready for a final render, you can turn off the [Interactive] render and turn on [Progressive] and click [Render with V-Ray]. It may differ from the Interactive render, so may need some adjustments to get things right. For example, often, you need to adjust the Exposure Value and Aerial Perspective. You will get a JPG, PNG, or TIFF file from this final render for your post-production, known as photoshopping. The final render will take a few minutes to a few hours depending on the size of the image and the complexity of the model (more points), material settings (reflectivity, bump, displacements), and number of lighting sources.

Press any of the directional arrow keys and then move the mouse cursor back on-screen with the missing window. (The arrow keys can also move the window up, down, right, or left if needed.) Can VRAY run without GPU?Intel 64, AMD64, or compatible processor with SSE4. 22 support. All sockets and cores are utilized when running CUDA x86 mode (with or without GPUs). No GPU is required in the system when running solely in CUDA x86 mode. How to check Vray render progress?When you have rendered your model, in the render window, in the bottom right hand side there is a sort of down 'chevron'. Click on this and you have some options, one of which is 'apply stamp' select this, and next to it there is a % symbol. How to save an image from a Vray frame buffer?Press and hold the icon to bring up the submenu:. Save current channel – Saves the current channel to an image file format;. Save all image channels to separate files – Saves all the render elements into separate files; Use to save the VFB color corrections to render elements.. |
