Tutorial Steps

Open the Example Scene

Begin by launching SketchUp.  Open the project file SU_quickstart_01_Doomo_Modny_II.skp, which can be downloaded from the Tutorial Assets section above.


Using the V-Ray Toolbar and Asset Editor

V-Ray provides a set of three toolbars that make up the V-Ray Toolbar. They are floating toolbars by default, but they can be docked as needed in the SketchUp interface.


V-Ray Toolbar in floating mode (default)



These toolbars provide easy access to V-Ray features:

  • V-Ray for SketchUp Toolbar – The main toolbar which includes buttons for the Asset Editor, Rendering, and the V-Ray Frame Buffer (VFB) which displays renders.
  • V-Ray Lights – The lighting toolbar which allows you to create and place a variety of V-Ray lights in the scene.
  • V-Ray Objects – The geometry toolbar which creates objects specific to V-Ray such as an Infinite Ground Plane, Proxies, and V-Ray Fur.


Click on the Asset Editor button on the toolbar to open the V-Ray Asset Editor.




The Asset Editor has four sections for managing V-Ray settings and scene objects which can be accessed by the tabs at the top of the editor:

  • Materials editor – Allows you to preview and edit materials. The Material List tab displays all materials in the scene. The Quick Settings tab allows you to edit the currently selected material.
  • Lights editor – Manages the lights in the scene. A V-Ray Sunlight is provided by default.
  • Geometry editor – List any V-Ray specific geometry in the scene, such as V-Ray Fur.
  • Settings section – Provides a multitude of settings for rendering the scene.

Additionally, the Asset Editor provides a Render button and VFB button, similar to the V-Ray Toolbar.



Working with Interactive Rendering

Interactive Rendering allows you to view a rendered version of your scene, and it will automatically update as adjustments to the scene are made. To start an Interactive Render, navigate to the Settings section of the V-Ray Asset Editor and enable the Interactive option. Next, click the Render with V-Ray Interactive button.



The VFB will launch and start to render. The render will become clearer over time.




Any changes made to the scene will automatically update in the interactive render. To test this out, enable SketchUp’s Shadows Toolbar, and then turn on Show/Hide Shadows. This will allow you to see shadows within SketchUp. Set the Time of day to around Noon.




Both the scene view in SketchUp and the Interactive Render in the VFB will update. You will see that the shadows are consistent between both views.

Interactive Render




To reduce calculation times, disable Show/Hide Shadows in SketchUp's Shadows Toolbar. Go ahead and change the Date and Time of day to evening to see how the sunlight changes in both direction and color. Feel free to experiment for yourself.




When you are ready to proceed, set the Time to around late morning and set the Date to August. The rendered scene should look like the following:



Replacing and Editing Materials

Next, we will replace existing materials in the scene with materials from V-Ray's Preset Material Library. Open the Asset Editor and go to the Materials section. To select a material to edit, select SketchUp's Paint Bucket tool.




Holding down the Alt key and clicking with the Paint Bucket tool will allow you to select a material. Let's select the stucco material on the surface of the house.




Both SketchUp's UI and the V-Ray Asset Editor will display the material information. Let's replace the stucco with one of V-Ray's material presets. Click the left facing arrow to expand the Asset Editor to reveal the material library.




V-Ray's Material Library contains a variety of ready-to-use materials that are optimized for V-Ray. Go to the WallPaint & Wallpaper category, and scroll down to find Stucco_F01_50cm. Simply drag and drop the icon from the Library into the right panel to add it to your Material List.




To replace the existing material, right click on the Stucco_F01_50cm material, and select Copy. Using the Paint Bucket tool + Alt key, select the existing stucco material on the house to select it again. Then right click on Stucco_1 and choose Paste. This will take all the parameters from the copied material and lay it on top of the assigned material.



Copying the new Stucco parameters.

Pasting the new parameters into the old Stucco material.




It's important to note that the stucco material that copied has a real-world size associated with it: 50cm. To change the material size, go to the SketchUp Materials panel and navigate to the Edit tab. Set the size accordingly. In this case, 50 cm is about 20” or 1'8", so enter this number in the horizontal value and the vertical value will update automatically.




With the new stucco material, the interactive render should look like this:




Using the same method, let's replace the grass material as well. Select the grass material using the same method as before with the Paint Bucket + Alt key. The Grass_2 material should be selected. Select the Ground category in the Material Library, and you’ll find several grass materials available. Drag Grass C over to the right to bring it into the scene.





Similar to how we replaced the stucco, right click on Grass_C and Copy it. Select Grass_2, right click on it, and Paste the new grass. The material size needs to be edited as well, so navigate to Material panel's Edit tab. Although 200cm is about 6.5 feet, enter 10’ for this material. This produces a more realistic grass appearance.




Finally, let’s replace the glass material with something nicer. Go to the Glass category in the Material Library, and drag Glass Window Neutral into the Material List.




Right click and Copy it to the clipboard. Select the glass object in the scene select the Glass_3 material. Right click to paste the glass from the library. This material will not need to have its size adjusted. The Interactive Renderer in the VFB will update to show us a nicer glass appearance in the scene.




Adding V-Ray Lights

Now that the glass has been replaced, the darkness inside the house is more noticeable. Let's add some lights to the scene. In the Asset Editor, collapse the Material Library and switch to the Lights section. There is only the basic Sunlight so far.



Before proceeding, click the Lock Camera Orientation button on the V-Ray Toolbar. This allows us to move the camera in the SketchUp scene without changing the Interactive Rendering view. This way the camera can move inside the house to add lights while keeping the same framing for rendering.



Once inside the house, click the Plane Light icon in the V-Ray Toolbar. In the scene, you should be able to draw the plane light along the surface of the ceiling. Switch back to the move tool and move the newly created Plane Light a small distance away from the ceiling.




The light will be visible in the Interactive Render, especially when the Time is changed to night.




To edit the light properties, expand the right panel of the Asset Editor with the right arrow.




Let's set the Intensity parameter to 80 to brighten the light. Light intensity is measured in Scalar units by default, but you have the option of changing the Units for each light as you prefer.

SketchUp groups and components can be turned into lights as well. Navigate in your scene to find this piece of geometry set into the overhang here outside the window, and select it. Click on the Mesh Light icon in the toolbar, and V-Ray converts that geometry into a light.





The newly created mesh light will be added to the Asset Editor where you can fine tune its properties. Increase its Intensity to about 60.




Set the Time to late morning again. Reset the camera back to the Final Scene view by clicking on the corresponding scene tab.




Here is what we have so far. Let’s work on some nicer grass!




Creating Grass with V-Ray Fur

For efficiency, the grass should only be created on this section of geometry closest to the camera. This section of geometry has already been separately grouped for your convenience. Select it in the scene.




Next, click the V-Ray Fur icon in the V-Ray toolbar. This adds V-Ray Fur parameters to the selected object. Note that the fur will only be visible in the render, not in the SketchUp scene view.




In the Geometry section of the Asset Editor you will see the newly created V-Ray Fur object. For ease of use, V-Ray Fur mimics standard grass by default. There are various other applications for V-Ray, but they will be covered in a later video.




Let's get a better view of the grass. Turn off the Lock Camera Orientation button in the V-Ray Toolbar and move the camera down a bit, and settle into a view closer to the ground. You’ll notice that there are actual blades of grass being rendered now.




Using Depth of Field

Before setting up the final render, we will cover how to setup depth of field. Navigate to the Settings section in the Asset Editor, and click open the Camera section. Enable Depth of Field, and you should notice the effect when the VFB updates.




Increase the Defocus value and you will notice the blur quickly affect the house. You will also notice that, by default, the camera's focal point is set fairly close to the camera.




To fix this set the Focal Point. In the Camera Settings, click the Pick Focal Point button and select a point on the wall of the house.




Right away the house will come into sharp focus, and the rest of the scene will be blurred.




The Defocus amount here is a bit much, so set the value to about 0.45 to give us the hint of depth of field in the foreground and the background. 



Setting up the Final Render

Now that the scene and camera settings are ready, let’s get this going for a final render. Stop the Interactive Render by clicking the Stop icon in the VFB.




Click to expand the Render Output section in the Asset Editor and set the image size to 900 by 900. Of course, you can render any size and aspect ratio you wish by using the provided options.




At the top of the Settings section, navigate to the Renderer options and disable Interactive for the final render. With the Progressive option, which is enabled by default, the V-Ray renderer will render the entire image quickly in Low quality and continue to increase the quality of the whole image over time. You can set your desired quality level here with the Quality slider which automatically balances image quality and the amount of time spent rendering. In this example, the value is set to High.




Make sure to re-align your view by clicking the Final Scene tab and then click the Render with V-Ray button. V-Ray will go through its rendering steps progressively, and you will see it develop in the VFB over time. Eventually, the renderer finishes resolving the image once it reaches High Quality. Here is our final rendered house:
