Looking for a smart way to boost realism in your renders? Learn how to import, adjust, and use Gaussian Splats in V-Ray for SketchUp.
Gaussian Splatting offers a powerful way to create realistic environments in V-Ray 7 for SketchUp using point cloud data. This tutorial will guide you through the process of importing, adjusting, and integrating Gaussian Splats into your scene.
1. Create a Gaussian Splat
Go outside and capture a 360-degree scan of an environment using drone footage. For this tutorial, we chose the bustling architectural landscape of Hanoi, a Vietnamese city rich in history and design. After that, use a photogrammetry tool like Postshot to process the footage and generate a point cloud dataset.
2. Import the Gaussian Splat into SketchUp
Use the Import Proxy button to bring the Gaussian Splat into your scene. To get an accurate photoreal look, adjust the scale factor and axis orientation to closely match its real-world dimensions.
3. Enhance the look and feel
Increase the preview percentage for better visual detail. Then, adjust the color tint to match that of the surrounding environment, and use the intensity parameter to correct exposure and brightness.
4. Integrate objects into the scene
Browse through the Chaos Cosmos library and place an object or two into the environment to add a greater life and energy to the scene. You will notice the lack of contact shadows due to the nature of Gaussian Splats.
5. Add contact shadows with a shadow catcher
Create a simple shadow catcher model using the point cloud preview. After that, apply a Wrapper Material to the shadow catcher. Enable, Alpha Contribution, Matte, and Shadows. This ensures realistic shadow interaction without affecting reflections or textures.
6. Apply the finishing touches
Rotate your scene around to establish the best angles, and make any final tweaks to the positioning and lighting.
Achieve photoreal renders with Gaussian Splatting
Using Gaussian Splats is a great way to blend objects into realistic environments without heavy geometry. Experiment with different settings to achieve the best results! This is just one of many new features in V-Ray 7 for SketchUp. Stay tuned for more tutorials!
