HOW TO RELIGHT AND RENDER GAUSSIAN SPLATS

Learn how to relight Gaussian Splats in Houdini 22 using SideFX Labs, Solaris, and Copernicus workflows. This tutorial covers preparing a Gaussian Splat for relighting, generating normals, extracting albedo, setting up USD lights, adjusting shadows, and bringing the relit result into COPs for rasterization and image-based refinement.

You’ll also explore practical techniques including shadow bias control, dome lighting, camera-based rasterization, color correction, sharpening, resolution adjustments, and near real-time lighting updates in Copernicus. This workflow is valuable for artists who want to relight and render Gaussian Splats in Houdini while maintaining interactive control over lighting, image quality, and final presentation.
