Platform

Houdini plugin for Houdini 20.5 through 22.0. Precompiled binaries are not available for Linux

GPU

None published. GSOPs runs inside SideFX Houdini 20.5 through 22.0 and draws through the Houdini viewport and renderers, so Houdini's own GPU requirements apply. GSOPs does not train splats

Pricing

Free download. Custom studio licences with support, source code, commercial usage and Linux builds from CG Nomads

License

AGPL-3.0 from GSOPs 2.0 onward, with GSOPs 1.0 under MIT. Custom studio licences available from CG Nomads

Gaussian Splatting in Houdini

Updated

July 2026

GSOPs is a toolkit from CG Nomads, the studio of David Rhodes and Ruben Diaz, that integrates Gaussian splatting into SideFX Houdini for artists, researchers and developers working in novel view synthesis, synthetic data generation and 3D content creation. GSOPs 3.0.0, released August 14 2026, supports Houdini 20.5 through 22.0 and adds mip-splatting support, import of splats from Apple's ml-sharp, a Bake node that converts splats to points, meshes and density volumes, and a NanoGS inspired Reduce node developed with Eyeline. GSOPs is open source under AGPL-3.0 from version 2.0 onward, after GSOPs 1.0 shipped under MIT, and CG Nomads sells custom studio licences covering support, commercial usage and Linux builds. Framestore's FX team used GSOPs to write splats natively out of Houdini on Superman, according to CG supervisor Kevin Sears, and Rodeo FX used it on Dune: Prophecy.

Platform Highlights:

  • Early Access Availability: GSOPs 2.0 launched as an early access release in November 2024. CG Nomads now gives supporters early access to new nodes ahead of general release.

  • WYSIWYG Editing: Users can view their updates in real time.

  • Open-Source and Community-Focused: GSOPs invites hobbyists, researchers, and professionals to engage, contribute, and experiment within an open-source ecosystem. Support is available through GitHub and a dedicated Discord community.

  • Radiance Field Applications: Known for supporting Radiance Field techniques like Gaussian Splatting, GSOPs is ideal for those interested in isolating objects, removing artifacts, relighting scenes, and enhancing visual realism in 3D models.

Core Features:

  • Synthetic Data and Model Training: Generate synthetic data with enhanced PNG support for alpha-masking, compatible with Postshot and NerfStudio.

  • Houdini Integration: Offers seamless import/export, rendering, and editing directly within Houdini 20.5 through 22.0, with compatibility for Houdini’s SOPs context.

  • Advanced Functionality: Includes nodes for image-based lighting, color correction via look-up tables, scene relighting, and splat transformations, providing extensive customization options.

Ideal For: GSOPs 2.0 is best suited for users in VFX, digital art, and research environments who need high-fidelity visual effects and flexibility for iterative workflows. It supports rapid prototyping and offers an extensive array of tools designed to leverage Houdini’s procedural capabilities.

Notable Update:

  • New and Updated SOP Nodes: Nodes like gaussian_splats_generate_training_data, gaussian_splats_transform, and GSplat Source add flexibility for color adjustments, object manipulation, and data generation, enhancing the early access platform’s functionality for users in need of a dynamic, customizable solution.

Getting Started with GSOPs 2.0

Available as a free download on GitHub, GSOPs is easy to install and integrate within Houdini’s environment. With comprehensive help cards, example scenes, and community support, GSOPs is accessible for both experienced users and those looking to explore 3D Gaussian Splatting.

Explore GSOPs 2.0 Early Access if you’re seeking a versatile, community-driven toolset designed for today’s cutting-edge 3D needs. For those looking to refine and contribute to the platform, your feedback is welcomed as GSOPs develops into its full release.

Frequently Asked Questions

Is GSOPs free?

GSOPs is a free download on GitHub under the AGPL-3.0 licence, which has applied since GSOPs 2.0, while GSOPs 1.0 was MIT licensed. Since GSOPs 2.0 it can run under the Houdini Commercial license for production use, and you can learn it for free with Houdini Apprentice.

What does GSOPs add to Houdini?

GSOPs adds import and export, WYSIWYG splat editing, cropping, deformation, relighting, color correction, and synthetic training-data generation. Version 2.6 added Solaris and Karma rendering support, 2.9 added Houdini 21 interoperability with native splat attribute layouts, and 3.0 added Houdini 22 support, mip-splatting, baking splats to meshes and volumes, and the Reduce decimation node.

Is the TouchDesigner GSOPs the same tool?

No. The TouchDesigner operator family also called GSOPs is an unrelated product from a different developer. The Houdini GSOPs is developed by CG Nomads (David Rhodes and Ruben Diaz).
