Blender 5.3: Gaussian splats, DLSS and the new compositor

Blender 5.3 lands on November 10, 2026, and this time the headline is not a UI tweak: Gaussian Splatting is built in, Cycles gets dispersion and DLSS, and the compositor stops being a single node tree.

What Blender 5.3 brings (and when it lands)

The official date is November 10, 2026, and the release is still in Release Candidate: details can move. It is the third stable build of 2026 and it is not LTS, so anyone who needs two years of stability stays on 5.2 LTS, with 5.2.3 from October 22 as the latest maintenance build.

Gaussian Splatting: the headline feature

A splat is not a mesh: it is a cloud of semi-transparent blobs that rebuilds geometry and shading from photos or video. It imports from PLY and SPZ as a point cloud type of its own, Points / 3D Gaussian Splats, and you work it with Geometry Nodes. Workbench, EEVEE and Cycles all render it with an emissive shader, and relighting is basic: swap the emission for a diffuse BSDF. There is no export, it cannot be rigged and Apply Transform misbehaves with the new attributes; for photos to mesh there is photogrammetry in Blender.

Cycles in Blender 5.3: dispersion and DLSS

Dispersion arrives in the Principled BSDF, inside the Transmission panel: it splits white light into rainbow colours. It brings Dispersion Scale and Abbe Number, and a lower Abbe number with a higher IOR means more dispersion. Cycles-only, sampling wavelengths at random, so it adds colour noise when you are short on samples.

The DLSS denoiser works in the viewport on NVIDIA GPUs: it reuses samples from previous frames and can upscale. It needs driver 620 or newer and the GPU enabled in Preferences; the Automatic mode does not pick it for you. Roughness anisotropy also reaches the Glass BSDF.

EEVEE and Vulkan: light nodes, panoramic cameras and a scene-breaking change

Material lighting nodes land (Light Accumulation, Light Info, Light Evaluation, Shadow Raycast) and open up toon shading and iridescence, while EEVEE finally gets panoramic cameras with seven projections. The serious warning: Sky Texture with a sun disc now actually lights the scene, so older files will look different until you turn Sun Disc off.

Vulkan becomes the default backend on Windows and Linux, with 1.1 as the new minimum, and Workbench picks up hardware-traced shadows. If you are still choosing an engine, EEVEE vs Cycles still holds up.

Compositor: an effects stack and Bloom is back

The compositor is no longer a single node tree but an effects stack, where each effect feeds the next one. Bloom returns as a bundled asset and goes in with one click. Playback cache gets up to 2x faster on GPU and Kuwahara improves 25 percent on CPU. To practise, try Start COMPOSITING in Blender.

Modeling, sculpting and weight painting

The Quad-Sphere primitive arrives and Loop Tools stops being a half-finished addon: three operators move into the program. Multires now shows textures and colour attributes while sculpting, and automasking reaches Vertex Paint and Weight Paint.

In Weight Paint the base brush becomes Add Weight, Paint is now Set Weight and spacing drops to 5 percent. This weight painting trick saves hours.

Animation and the Video Sequencer

You can now copy and paste animation in world space across several objects or bones, though it still fails when pasting onto objects with constraints. There is an operator to convert rotation modes (Ctrl+R in Pose Mode). The Video Sequencer gets full ripple editing, Blade 2.0 with cut preview and early OpenTimelineIO support.

Compatibility: what to check before you update

In Grease Pencil the Frame Duration feature is disabled and end frames become regular frames with an empty drawing. In Python, GPUBatch.draw_instanced prefers gpu_InstanceIndex. Open the project with a backup, review addons and follow the walkthrough on updating Blender without breaking projects.

Conclusion

Blender 5.3 is not more of the same: Gaussian Splatting and the effects stack change the workflow, and DLSS changes how the viewport feels with NVIDIA hardware. This is written while the release is still in Release Candidate, and it gets updated on launch day with the final list.
