Blender has released version 5.3, adding native support for importing and rendering 3D Gaussian Splats. The release also brings changes to Cycles, EEVEE and the compositor, though Blender says some splat rendering limitations remain and performance is still being optimized.
Blender 5.3 has been released with native support for 3D Gaussian Splats, allowing artists to import splat data, work with it as point clouds and render it in EEVEE, Cycles or Workbench. The update also adds rendering, shading and compositing features, expanding Blender’s tools for artists using reconstructed 3D scenes and other visual effects workflows.
According to Blender’s release page, version 5.3 can import Gaussian Splat data from PLY, SPZ and glTF files. The splats are stored as a distinct type of point cloud and can be processed with Geometry Nodes. They can also be previewed in Workbench’s solid mode and rendered in EEVEE and Cycles.
Each splat includes attributes for its scale and rotation, along with radiance and opacity information. Blender says the default rendering approach uses an emissive shader, with radiance available at the shading point. The release describes rudimentary relighting support: users can replace the Emission node with a hard-surface shader such as Diffuse BSDF.
Other additions include dispersion in Cycles’ Principled BSDF, which can reproduce rainbow effects in glass and gemstones, and anisotropy support for the Glass BSDF and the Principled BSDF’s transmission component. Cycles also gains NVIDIA DLSS 4.5 Ray Reconstruction as a denoiser; Blender says it requires NVIDIA driver version 620 or newer.
Gaussian Splats Enter Blender Workflows
Gaussian Splats are used to reconstruct scenes from photographs or video. Native import and rendering in Blender can let artists bring those reconstructions into a familiar 3D application, inspect them, combine them with other scene elements and make changes through Geometry Nodes. That may reduce the need to treat splat data as an isolated asset or rely on a separate viewer for basic presentation.
The workflow is not limited to one rendering engine: Blender lists support in EEVEE, Cycles and Workbench. That gives users options for interactive previews and rendered output, while the ability to manipulate splats as point clouds opens them to procedural workflows. The release page does not provide performance benchmarks or quantify how much time the new support saves.
The wider set of changes also matters to production work. Cycles’ dispersion and denoising options affect rendered imagery, while EEVEE gains lighting-related shader nodes and panoramic camera support. In the compositor, users can stack effects such as Bloom, Chromatic Aberration, Film Grain and Vignette, then edit their underlying node groups.

How Blender Handles Splat Data
Gaussian Splats represent a scene with many small, soft, transparent blobs that combine to convey geometry and shading. Blender says its implementation represents them as a special kind of point cloud, with attributes that describe each splat’s size, orientation, radiance and opacity. Additional spherical-harmonics coefficients describe radiance beyond the base value.
Version 5.3 also changes other parts of Blender. EEVEE can render panoramic cameras, including equirectangular, cubemap, fisheye and mirror-ball projections. Its release notes list limitations: depth of field, ray tracing and volumetric temporal reprojection in the viewport are not supported by the current panoramic implementation.
The compositor adds a new Effects tab for stacking built-in effects and custom node groups. Blender also reports that 17 Geometry Nodes are now supported in the compositor, including bundle, math, logic and utility operations. These features are part of the same release, but Blender’s announcement does not provide a single performance or adoption measure for the update.
“Performance is still being optimized.”

Rendering Limits Still Remain
Blender’s release material does not give a detailed performance comparison for Gaussian Splat rendering, and it says optimization is ongoing. The extent of the color inaccuracies associated with differences between sRGB authoring tools and Blender’s linear color space is also not quantified.
Relighting is described as rudimentary, rather than as a complete lighting workflow. The release notes do not specify how relighting behaves across different assets or scenes, or whether further limitations apply beyond those described. Users may need to test their own files and compare the results with their source applications.
Blender’s announcement also does not state a specific release date in the supplied material. For EEVEE panoramic rendering, the listed gaps include depth of field, ray tracing and viewport volumetric temporal reprojection. The release information does not give dates for adding those capabilities.
Testing the New Rendering Tools
Artists can try the release by importing supported PLY, SPZ or glTF splat files and checking their appearance in Blender’s available display and render options. For Cycles DLSS denoising, users need an NVIDIA driver version 620 or newer, according to the release notes. Those testing splats should also watch for the color-space differences Blender describes and assess relighting against their own material and lighting needs.
Blender says splat performance is still being optimized, but the provided announcement does not set out a schedule for follow-up fixes or future support. Further details about performance improvements, the scope of relighting and the unsupported EEVEE panorama features remain to be confirmed in later release information.
Key Questions
What Gaussian Splat files can Blender 5.3 import?
Blender’s release page lists PLY, SPZ and glTF formats. Imported splats are represented as a distinct point-cloud type.
Which Blender renderers support Gaussian Splats?
The release lists rendering support in EEVEE and Cycles, as well as previewing in Workbench solid mode.
Can Gaussian Splats be edited in Blender?
They can be processed with Geometry Nodes. Blender also exposes attributes for splat scale, rotation, radiance and opacity.
Does Blender 5.3 support relighting Gaussian Splats?
Blender describes relighting as rudimentary. Its release page says users can replace the default Emission node with a hard-surface shader such as Diffuse BSDF.
What are the known limitations?
Blender says splat performance is still being optimized and warns of possible color inaccuracies tied to sRGB-to-linear color differences. For EEVEE panoramic rendering, the listed limitations include depth of field, ray tracing and viewport volumetric temporal reprojection.
