Adding a sky background in VRay SketchUp is a simple yet effective way to enhance the realism of your 3D scenes. It allows you to create stunning outdoor environments with realistic lighting and atmospheric effects. In this tutorial, we will explore the step-by-step process of adding a sky background in VRay SketchUp.
Step 1: Setting up the Scene
Before we can add a sky background, it is important to set up our scene properly. Start by opening your SketchUp model and navigating to the “Window” tab in the main menu. From there, select “Model Info” and then choose “Background” from the sidebar.
Step 1.1:
In the “Background” settings, make sure that the “Sky” option is selected under the “Use Background” section. This will enable us to add a sky background to our scene.
Step 2: Accessing VRay’s Asset Editor
In order to add a sky background, we need to access VRay’s Asset Editor. To do this, navigate to the top menu and select “Extensions.”
From there, choose “V-Ray” and click on “Asset Editor. “
Step 3: Adding a Sky Background
Once you have opened VRay’s Asset Editor, locate the “Environment” tab at the top of the window. Click on it to reveal various environment settings.
Step 3.1:
Within the Environment settings, you will find an option called “GI (skylight).” Toggle this option on by clicking on its corresponding checkbox.2:
Beneath the GI (skylight) option, you will find a small icon with three dots. Click on this icon to open the Sky Parameters window.3:
Within the Sky Parameters window, you can customize your sky background by adjusting various settings. These include:
- Sky Model: Choose between “Preetham Physical Sky” and “Hosek-Wilkie Physical Sky” to determine the appearance of your sky.
- Turbidity: This setting controls the amount of haze in the atmosphere. Higher values create a hazier sky.
- Horizon Height: Adjust this setting to change the height at which the horizon line is positioned within your scene.
- Sun Disk Intensity: Modify this value to control the brightness of the sun in your sky background.
Step 4: Fine-tuning and Additional Options
If you want to further enhance your sky background, VRay offers additional options for customization.
Step 4.1:
In the Sky Parameters window, you will find an option called “Advanced.” Click on it to reveal more settings.2:
The advanced settings allow you to adjust parameters such as “Ground Albedo,” “Sun Intensity Multiplier,” and “Sun Size Multiplier.” These settings can greatly influence the overall appearance of your sky background.
