How Do I Change the Shadow in VRAY SketchUp?

Are you looking to enhance the visual appeal of your VRAY SketchUp renders by changing the shadow settings? In this tutorial, we will walk you through the step-by-step process of modifying the shadow parameters in VRAY SketchUp to achieve the desired effect. Let’s dive in!

Step 1: Accessing the Shadow Settings

To begin, open your SketchUp project and navigate to the VRAY toolbar. Click on the “Options Editor” icon to access the VRAY settings.

Once inside the Options Editor, locate and expand the “V-Ray for SketchUp” category. Within this category, scroll down and select “Shadows”. This will open up a panel with various shadow-related parameters that can be modified.

Step 2: Adjusting Shadow Intensity

One of the essential elements of a realistic render is getting the shadow intensity right. To modify this setting, find the “Shadow Intensity” parameter under the Shadows panel.

You can simply type in a value or use the slider provided to adjust it. Higher values will result in darker shadows, while lower values will lighten them.

Note: It’s crucial to strike a balance between achieving realistic shadows and maintaining visibility of your model’s details.

Step 3: Tweaking Shadow Color

If you want to give your shadows a unique touch, you can alter their color. To do this, look for the “Shadow Color” parameter within the Shadows panel. You have two options here:

  • Pick From Scene: Selecting this option allows you to sample a color from your scene by clicking on any surface with an appropriate color.
  • Select Color: Choosing this option opens a color picker dialog box, allowing you to manually set the desired shadow color.

Experiment with different shadow colors to find the perfect combination that enhances your render’s visual impact.

Step 4: Modifying Shadow Softness

The softness of shadows can greatly affect the overall rendering quality. To adjust the shadow softness, locate the “Shadow Subdivision” parameter in the Shadows panel. This parameter controls how many subdivisions are used to calculate the shadow’s edges.

Increasing the value will result in smoother and softer shadows, while decreasing it will produce sharper and more defined shadows.

Step 5: Changing Shadow Bias

The Shadow Bias parameter determines how close an object needs to be to cast a shadow on another surface. This parameter is useful when dealing with issues such as gaps or flickering shadows.

To modify the Shadow Bias, find its corresponding parameter within the Shadows panel. Adjusting this value will alter how shadows interact with objects in your scene. Experiment with different values until you achieve the desired result.


In this tutorial, we explored the process of changing shadow settings in VRAY SketchUp. By adjusting parameters such as intensity, color, softness, and bias, you can create visually stunning renders that enhance your architectural designs or 3D models.

Remember to strike a balance between realism and artistic expression when customizing your shadow settings. Happy rendering!
