Blender 5.3 adds native support for 3D Gaussian Splats, allowing users to import PLY, SPZ and glTF files as point clouds, process them with Geometry Nodes, and render them in EEVEE, Cycles and Workbench solid mode. The release also adds rendering, shading and compositor features; Blender says Gaussian Splat performance is still being optimized.
Blender 5.3 has been released with native support for 3D Gaussian Splats, a representation used to reconstruct scenes from photographs or video. Users can import splats from PLY, SPZ and glTF files, process them as point clouds with Geometry Nodes, and render them in EEVEE, Cycles or Workbench solid mode, according to Blender’s release notes.
Blender stores Gaussian Splats as a distinct type of point cloud, with attributes for each splat’s scale, rotation, opacity and radiance. That structure allows artists to work with the data in Geometry Nodes rather than treating a splat scene only as a finished image. Blender says the feature supports import, viewport preview and rendering within the application.
By default, splats use an emissive shader. The radiance attribute provides the resolved radiance at the current shading point. Blender describes relighting with a hard-surface shader, such as Diffuse BSDF, as rudimentary. The release notes also warn that rendering can show inaccuracies because many authoring tools use sRGB color while Blender works in linear color, particularly in areas with low opacity and high radiance.
The release includes changes beyond splats. Cycles adds dispersion to the Principled BSDF and anisotropy support for the Glass BSDF and Principled transmission. Blender also lists DLSS 4.5 Ray Reconstruction as a Cycles denoiser, requiring NVIDIA driver 620 or newer. EEVEE gains panoramic camera support and material lighting nodes; the compositor adds stackable scene effects, including Bloom, chromatic aberration, film grain and vignette.
A New Route for Scene Reconstruction
Native splat support gives Blender users a way to bring a scene representation commonly produced from photo or video reconstruction into a familiar 3D workflow. They can inspect and manipulate it alongside other Blender content, use Geometry Nodes to process it, and render it with the application’s listed renderers. This may reduce the need to rely on a separate viewer for basic splat work, although the release notes do not claim that Blender replaces dedicated reconstruction or editing tools.
The feature’s limits matter for production use. Blender says performance remains under optimization and flags possible color inaccuracies, while describing relighting as rudimentary. Artists evaluating the release for final output will need to test their own scenes and workflows rather than assume every imported asset will match its appearance in its original authoring tool.
The other changes broaden the update’s relevance: Cycles users gain additional shading and denoising options, while EEVEE and compositor users get new camera, lighting and effects tools. The release presents Blender 5.3 as a set of workflow additions across several parts of the application, not solely a splat import update.

How Splats Fit Blender’s Data Model
Gaussian Splats are made from many small, soft, transparent elements that combine to represent a scene’s appearance. Blender’s release notes describe them as commonly used to reconstruct 3D scenes from photographs or video. The 5.3 implementation represents them as point clouds, while adding splat-specific attributes such as scale, quaternion rotation and radiance data, including spherical-harmonic coefficients.
That representation is the basis for Blender’s new workflow: import supported files, work with the point-cloud data, preview it and render it. The release notes identify PLY, SPZ and glTF as supported import formats. They also list several limitations and implementation details, including the default emissive shading and the lack of optimized performance, rather than presenting the feature as a finished solution for every use case.
“Performance is still being optimized.”
— Blender 5.3 release notes
Performance and Color Limits
The release notes do not give benchmark figures for importing or rendering Gaussian Splats, so the speed users can expect on particular hardware is unclear. Blender says optimization is ongoing but does not specify a schedule or a target performance level.
It is also unclear how broadly the color-space mismatch affects different files and scenes; Blender identifies conditions where inaccuracies may be more apparent but does not quantify their scale. The notes characterize relighting as rudimentary, without detailing how reliably it works across assets. The source material does not provide a release date, so one is not stated here.
Testing the New Splat Workflow
Users can try the new workflow by importing a supported PLY, SPZ or glTF splat file into Blender 5.3, then previewing, processing or rendering it. For Cycles users considering the new DLSS denoiser, Blender lists NVIDIA driver version 620 or newer as a requirement.
Blender says splat performance is still being optimized, but the release material does not give a date for follow-up changes. For now, the main practical next step is testing imported assets in the intended renderer and checking appearance, color and performance against the original files.
Key Questions
What is new for Gaussian Splats in Blender 5.3?
Blender can import PLY, SPZ and glTF splat files, represent them as point clouds, process them with Geometry Nodes, preview them in Workbench solid mode and render them in EEVEE or Cycles.
Can Blender 5.3 relight Gaussian Splats?
Blender describes relighting support as rudimentary. Splats use an emissive shader by default, and the release notes say users can try replacing the Emission node with a hard-surface shader such as Diffuse BSDF.
Are there known limits to splat rendering?
Yes. Blender says performance is still being optimized and warns of possible inaccuracies from differences between sRGB color in many authoring tools and Blender’s linear color space. It singles out areas with low opacity and high radiance.
What else does Blender 5.3 add?
The release also adds Cycles shading and denoising features, panoramic cameras and material lighting nodes in EEVEE, and stackable compositor effects such as Bloom, film grain and vignette.
