Blender 5.3 can import and render 3D Gaussian splats

Blender developers Mark van de Ruit and Sergey Sharybin announced on 30 October 2026 that Blender 5.3 adds initial native support for 3D Gaussian splats. Blender 5.3 Beta can import, edit and render this data. Support includes PLY and SPZ files, as well as loading splats from USD.

How Gaussian splats work in Blender 5.3

Gaussian splatting creates a three-dimensional scene representation from photographs. The resulting data is not a traditional mesh, but a radiance field made up of many small Gaussians. According to the Blender developers, this format can represent complex shapes, lighting information, transparency, hair-like features and fine details within a single object.

In Blender, splats are treated as a point cloud type. The Pointcloud Type node added to Geometry Nodes makes this structure visible. Splats contain position, three-axis scale, quaternion rotation and radiance data. Radiance is more than simple color information: it also includes coefficients that encode view-dependent lighting. To import a supported file, simply drag it into the viewport.

EEVEE and Cycles render differently

EEVEE and Workbench rasterize splats as surfaces facing the camera. Blender 5.3’s initial EEVEE implementation uses dithered transparency. The developers note that this approach can produce noisy results for now, so they recommend increasing the viewport or render sample count. For the expected result in Workbench, set Viewport Shading lighting to Flat.

Cycles uses a ray-tracing approach. It calculates intersections between each ray and the splats, then evaluates opacity at the intersection point using a stochastic method. This implementation works with Cycles features such as reflections and indirect lighting. However, because Cycles and EEVEE use different technical approaches, some splat scenes created specifically for EEVEE may not look the same in both engines.

Both engines have basic relighting support. The developers emphasize that this is still at an early stage. The current approach estimates splat normals for lighting calculations; they note that topics such as albedo extraction could be addressed in the future for better results.

Areas still under development

According to the Blender team, EEVEE often draws data that is hidden behind other splats. This creates additional overdraw and can affect performance, especially on low-powered devices. Improvements to GPU culling are planned for future releases. The team also says that existing editing tools for point clouds can feel cumbersome in splat workflows.

Impact on architecture and visualization workflows

This support gives architects, interior designers and visualization teams a new way to bring photo-captured scenes into Blender and use them alongside existing scenes. Support for PLY and SPZ files, as well as loading from USD, makes it possible to try data from different sources. However, Gaussian splats do not produce meshes, so they should not be treated as the same data type as traditional polygon models.

Choosing a render engine also matters in the workflow: test the impact of sample count and scene density in EEVEE, and the different rendering approach in Cycles. Performance limitations on low-powered devices should be considered in particular. Since the Blender team’s announcement does not specify hardware requirements or a separate licence for this feature, teams should test it with their existing setups and verify its behavior while it is still in beta.
