[Dev News] Blender 5.3 Released

[xSicKxBot]

Blender 5.3 is here and its jam packed with exciting new features an improvements. Highlight features of Blender 5.3 include:

Gaussian Splats: Blender 5.3 introduces native support for importing and rendering 3D Gaussian Splats (from PLY, SPZ, and glTF files) in Cycles, EEVEE, and Workbench. They can also be manipulated using Geometry Nodes, though exporting them is not yet supported.

3 New Loop Tools: Three essential operators from the Loop Tools add-on have been integrated directly into Blender’s Edit Mode. These include Relax Edge Loops, Curve Edge Loops Between Selected, and Fit Edge Loops To Annotation.

DLSS Support: Cycles now utilizes NVIDIA DLSS 4.5 Ray Reconstruction as a powerful viewport denoiser. This upscales and reuses samples from previous frames for faster look development, requiring NVIDIA driver 620 or newer.

GLTF/USD Improvements: USD workflows now feature Collection Importers, which conveniently store import settings with collections for easy one-click re-imports. The glTF format has also been upgraded to support Gaussian Splat imports, KTX2 textures, and animation pointers.

Assets in Extensions: Asset libraries can now be packaged and distributed seamlessly as extensions. This integration allows users to pull public-domain CC0 libraries, such as those from Poly Haven, directly from the Blender Extensions platform.

New Project System: An optional project system utilizes a

root directory to keep complex production pipelines organized. Files within the project can share variables, path templates, dedicated asset libraries, and color-management configurations.

Vulkan by Default: Vulkan 1.1 is now the default graphics backend on Linux and non-ARM Windows systems. This architectural shift away from OpenGL is designed to deliver better baseline viewport performance.

Dispersion in Cycles: The Principled BSDF’s Transmission panel now supports dispersion, which realistically splits white light into rainbow fringes. This creates highly photorealistic results for product renders involving glass, diamonds, and perfume bottles.

VSE Ripple Editing: The Video Sequencer received a massive update with a complete ripple editing framework, including Ripple Trim, Ripple Delete, and a rewritten Blade 2.0 tool. It also features initial OpenTimelineIO import and export support for migrating edits to other video software.

Compositor Effects Stack: The compositor has been fundamentally restructured around a new effects stack with interactive playback caching. GPU playback performance has been doubled, making the processing of EXR sequences substantially faster.

EEVEE Panoramic Cameras: The EEVEE engine now natively renders seven panoramic projections, including equirectangular and fisheye lens models. This addition allows artists to generate 360-degree virtual tours and backgrounds directly from the real-time engine.

Grease Pencil Updates: 2D artists get new lasso and box selection tools in Draw Mode, alongside a Carver tool that cuts shapes out of strokes. Grease Pencil also gains dedicated input nodes to enable more complex, procedural 2D workflows.
