Blender 5.3 development builds add native 3D Gaussian splat import and rendering. You can bring PLY and SPZ captures into Workbench, EEVEE, and Cycles without a third-party add-on. The work is documented in the Blender 5.3 rendering release notes.
Blender 5.3 is still in development and is scheduled for November 10, 2026. The details below describe the current development build and may change before release.
Most real scenes still mix splats with ordinary mesh geometry. Floors, trim, and hero props usually need UV-based PBR materials. Our normal map vs height map in Blender and Node Wrangler texture setup guides cover that mesh side when a scan handles the environment.
What is Gaussian splatting?
3D Gaussian splatting reconstructs a scene from photographs or video. It uses many small, semi-transparent Gaussians instead of a polygon mesh. Each splat stores position, scale, rotation, opacity, and radiance. Together they can represent detailed captured rooms, objects, and outdoor sets.
In Blender 5.3 these captures live on point clouds. Blender adds a 3D Gaussian Splats point cloud type with splat-specific attributes. That is separate from a textured mesh workflow with UVs and Principled BSDF maps.
What's new in Blender 5.3?
The first native implementation includes:
- PLY and SPZ import. Blender detects Gaussian splats in supported PLY files and imports SPZ up to version 4.
- Point Cloud support. Scale, rotation, opacity, and radiance attributes ride on the new splat point cloud type.
- Geometry Nodes. Import SPZ and Set Point Cloud Type nodes work with splats. Import PLY can output a splat point cloud when the file carries splat data.
- USD import. Blender can import the
UsdVolParticleField3DGaussianSplatschema. - Rendering in Workbench, EEVEE, and Cycles. All three render engines can draw Gaussian splats.
Blender documents the work in its rendering notes and Pipeline and I/O notes.
How to import Gaussian splats in Blender 5.3
Use File → Import for PLY or SPZ, or wire the new Geometry Nodes import nodes. The PLY importer looks at geometry and attributes to detect splats. SPZ import converts coordinate systems to Blender conventions. Files from some capture tools may still need a manual rotation after import.
USD assets that use the Gaussian splat schema are supported on import as well.
Exporting splats is not available in this first release. The focus is bringing existing captures into Blender for layout, lighting tests, and rendering.
Can Cycles and EEVEE render Gaussian splats?
Yes. Workbench, EEVEE, and Cycles can render Gaussian splats in Blender 5.3.
By default Blender shades splats with emission driven by stored radiance. There is also basic experimental relighting. You can replace emission with a surface shader such as Diffuse BSDF so a splat picks up scene lights. That path is not a full relighting workflow yet.
Mesh materials next to splat captures
Splat renders rarely replace every surface in a shot. You might keep a scan for the room and build new mesh furniture, roads, or ceiling planes with standard PBR.
twirl materials ship as separate albedo, normal, roughness, metallic, and height maps. You can download public sets from the concrete materials or stone materials hubs, or generate a custom surface with the AI PBR material generator. twirl Connect for Blender can import a finished material when you want to skip manual node wiring.
That workflow is unchanged by splats. It is the usual way to add editable mesh surfaces around a capture. For broader context on generated vs scanned assets, see the state of AI 3D generation in 2026.
Current limitations
Blender lists several limits for this first implementation:
- Rendering performance is not yet optimized.
- Gaussian splat export is not available.
- Color and transparency can differ from the source capture, especially where opacity is low and radiance is high.
- Apply Transform does not correctly handle all splat attributes, including scale, rotation, and spherical harmonics.
Check these before you commit a splat-heavy scene to production. The official limitations section has the precise wording from the release notes.
Blender 5.3 release date
Blender 5.3 is expected on November 10, 2026. Native Gaussian splat import and rendering are already documented for that release. As of October 7, 2026 they remain development features in pre-release builds.
