01 DCC (3D content-creation apps)
3DGS isn't limited to game engines anymore — it's become workable directly inside the 3D content-creation apps used in everyday VFX pipelines. Here's how each app supports it, and where to get it.
| Software | Rating | Details | Where to get it | License |
|---|---|---|---|---|
| Maya + Arnold (Autodesk) | ◎ Top pick for relighting | Native support arrived with the latest Arnold. You can output the color captured at scan time as-is, or let scene lights relight the splat — useful for shots where you need it to sit alongside CG elements. Because Arnold's integrated plugins all support it, any DCC with Arnold handles splats the same way. GPU rendering is limited to NVIDIA GPUs on Windows and Linux | arnoldrenderer.com → | Commercial ($55/mo or $430/yr, subscription only) |
| OctaneRender (OTOY) | ◎ Top pick for path tracing | A GPU renderer available standalone and through its many DCC integration plugins (C4D, Maya, Blender, 3ds Max, Houdini, and more). Octane handles gaussian splats natively and renders them fully path traced rather than rasterized, so 3DGS participates directly in CG-side reflections, GI, and depth of field. The current release is stable enough for production work and reads SPZ as well. The same splat features work from whichever DCC you render in | home.otoy.com → | Commercial (subscription) |
| Houdini 22 | ◎ Top pick for power users | Native support. Splats can be transformed and animated with node-based workflows just like any other point cloud, and rendered directly in Karma. You can also render them through Arnold. Licensing cost and the learning curve are steep, though, so it's overkill if all you want is to look at a splat. Case study: the Houdini 22 × ComfyUI hybrid workflow | sidefx.com → | Commercial (free Indie/Apprentice tiers available) |
| Blender | ◎ Best value | Handled via the "3DGS Render" add-on from KIRI Engine. The current release renders in both Cycles and Eevee, and supports editing and optimization alongside splat animation. Rigging and light baking are starting to appear as experimental features. It's free to install, but being dependent on a third-party add-on, it can get heavy on large datasets | GitHub → | Open source, free |
| 3ds Max 2027 | ◎ Top pick for editing | Native support landed in the core app with the latest release. It can load PLY/SPZ/LCC directly, and the new Point object plus its dedicated modifiers let you select and manipulate splats. Because ordinary modifiers like Bend and Twist just work, this is currently the only tool that treats a splat as an editable scene element rather than a fixed asset — its one real edge over the rest. Rendering goes through Arnold, and V-Ray's (Chaos) native support, with relighting, is still an option too | autodesk.com → | Commercial ($255/mo or $2,010/yr; Indie $330/yr) |
| Cinema 4D | ○ Good fit for motion graphics | Handled via a plugin from Octane (OTOY). It can load PLY files from Luma, Polycam, and NeRDF Studio, and pairs well with motion graphics work. Octane's splat support is now stable enough for production work (see the OctaneRender row above). Arnold also handles splats here. Case study: generating "aerial shots" from 3DGS (a C4D → Octane workflow) | home.otoy.com → | Commercial (subscription) |
| Nuke 17 (Foundry) | ◎ Top pick for compositing | Native support in the core app since the latest release. On the overhauled USD-based 3D system, splats can be loaded, viewed, manipulated, rendered, and exported entirely inside Nuke, which means you can bring 3DGS directly into a live-action composite. For VFX compositing against a scanned background, this is currently the most direct route | foundry.com → | Commercial (subscription) |
| After Effects | ○ Good fit for motion graphics and compositing | Handled by a third-party "Gaussian Splatting" plugin (aescripts). It displays .ply files in real time on the GPU and supports cropping, color adjustment, and depth-pass export. This depends on a paid plugin rather than native app functionality | aescripts.com → | Commercial (paid plugin) |
02 Viewers & editors
These are the tools you reach for when you need to check a deliverable, or do cropping and color adjustments entirely in the browser. The list spans everything from fully browser-based tools to developer-facing rendering libraries and mobile apps.
| Software | Rating | Details | Where to get it | License |
|---|---|---|---|---|
| Locahun 3D Viewer (our own product) | — Not rated (our own product) | An offline, browser-only viewer we built in-house on top of Spark, designed for handling massive 3DGS datasets. Try a sample scene right now — no download or sign-up required | Try a sample → | In-house product (free demo) |
| SuperSplat (PlayCanvas) | ◎ Top pick | A fully browser-based 3DGS editor with cropping and color editing. A lightweight viewer meant purely for exported output is distributed as a separate repository | Editor → Viewer → | MIT, free |
| LichtFeld Studio (MrNeRF) | ◎ Top pick end-to-end from training | An open-source native app that covers everything from training on captured data (COLMAP), through brush/lasso/polygon-selection editing, to exporting PLY/SPZ/SOG and a standalone single-file HTML viewer. Training runs faster than the reference implementation, and recent releases also support LOD workflows. It can be extended with Python plugins too. CUDA is required, so it won't run on machines without an NVIDIA GPU | GitHub → lichtfeld.io → | GPLv3, free |
| Brush (ArthurBrussee) | ○ No NVIDIA GPU required | An open-source training and display app. Because it doesn't depend on CUDA, it runs on AMD and Intel GPUs and Apple Silicon in addition to NVIDIA, across native Windows/macOS/Linux/Android and even in-browser training. Research-derived extensions are still thin on the ground, and the developers themselves describe it as experimental | GitHub → | Apache 2.0, free |

05 Industrial platforms (robotics / geospatial)
3DGS isn't just for film and video production. Platforms that put real-world scans to work as "training environments for robot AI" or "city-scale geospatial data" have matured rapidly of late. Knowing about these secondary uses for captured footage can change how you think about the value of your scan data.
| Platform | Rating | Details | Where to get it | License |
|---|---|---|---|---|
| NVIDIA Omniverse / Isaac Sim(NuRec) | ◎ Top pick for robotics | Isaac Sim integrates the NuRec family of libraries, which rebuild 3DGS environments from real-world scans, and Omniverse RTX renders 3DGS natively. You can run robots through the scanned real-world space and mass-produce synthetic training data — imagery, depth, and more. For autonomous-driving use cases, there's also a CARLA integration. Case study: bringing 3DGS into NVIDIA Isaac Sim | developer.nvidia.com → | Free (personal / evaluation); commercial use requires an NVIDIA license |
| Cesium(3D Tiles) | ◎ Top pick for city scale | 3DGS is now formally part of 3D Tiles, enabling tiered LOD streaming through CesiumJS, Cesium for Unreal, and Cesium ion. It can deliver everything from city-scale coverage to centimeter-level detail with geographic coordinates attached, built on the standard glTF extension plus SPZ compression. For digital-twin and GIS use cases, this is currently the mainstream route for 3DGS | cesium.com → | CesiumJS is Apache 2.0; ion is a commercial plan |
