Blender 5.3 brings native handling of 3D Gaussian splats into the viewport via drag-and-drop support for `.PLY`, `.SPZ`, and USD files. Splats function as specialized point clouds with distinct scaling, rotation, and spherical harmonic attributes, starting with a default emissive material. All native renderers support these assets, with EEVEE and Workbench utilizing 2D quads while Cycles applies a stochastic ray-intersection method. Relighting support for these scene captures currently remains in an early stage of development.

In Blender 5.3, we are introducing initial support for 3D Gaussian splats! This enables importing, editing, and rendering of fast, high-quality scene captures.
A lot of groundwork has been done to integrate 3D Gaussian splats (gsplats) into Blender natively, and we’ll continue to refine our implementation in upcoming releases. In this post, we’ll outline how to use gsplats, how they’re implemented in Blender, and what the current limitations are.
What are Gaussian splats?
3D Gaussian splatting is a recent rendering technique in which sets of photos are turned into a specific 3D reconstruction. This doesn’t produce a mesh, but a radiance field made of many tiny Gaussian blobs. It’s similar to a point cloud, but able to represent more varied structures. Gsplats can describe complex scenes with materials, lighting, transparency, hair, and fine details, all in a single object.
Getting Started
Blender supports importing gsplats in the `.PLY` and `.SPZ` formats, and additionally can load them from USDs. Example gsplats files can be found online, created with professional capture tools, or even made with your phone. To showcase this, we…
Retail deals on Vizio's Mini LED Quantum sets provide an accessible option for buyers prioritizing privacy over integrated platforms. By skipping the initial setup prompts, consumers can prevent corporate telemetry while running dedicated streaming devices or consoles instead. This bypass feature addresses mounting user frustration regarding automated tracking across modern budget displays.
Ground teams have established communication with the newly launched Google Suncatcher prototype to test artificial intelligence operations directly in orbit. The mission is designed to evaluate how specialized hardware withstands radiation and extreme thermal environments for future distributed networks. Success could lead to larger satellite constellations capable of running off-planet machine learning workloads in the 2030s.
Following an unprecedented security breach, the world's largest digital asset exchange has partnered with the FBI to trace billions in missing capital while guaranteeing complete restitution for its 300 million users. Investigators discovered a sophisticated multi-pronged intrusion that utilized self-destruct mechanisms to actively erase forensic evidence. Blockchain analytics groups attribute the massive operation to state-sponsored actors seeking revenue streams to bypass severe international sanctions.
