Release Of Free 3D Modeling System Blender 5.3

The Blender Foundation has published the release of a free 3D modeling package Blender 5.3, suitable for solving various tasks related to 3D modeling, 3D graphics, computer game development, simulation, rendering, compositing, motion tracking, sculpting, animation creation and video editing. The code is distributed under the GPL license. Ready-made builds generated for Linux, Windows and macOS. Also continues to be supported LTS branches of Blender 5.2 and 4.5, updates for which will be generated until July 2027 and 2028, respectively.

Among added improvements:

• On Linux and Windows, the default backend is enabled using the Vulkan graphics API.
• Added built-in support for the 3D Gaussian Splats technique, allowing you to recreate 3D scenes based on photos and videos, and design them in the form of a point cloud instead of a polygonal mesh, which allows you to achieve photorealistic quality when rendering. Each point in the cloud is a miniature elongated 3D sphere with information about size, rotation and color. It supports importing point clouds from files in PLY, SPZ and glTF formats, processing through geometric nodes, previewing through a 3D viewport and rendering in the EEVEE and Cycles engines.
• The Cycles rendering engine supports dispersion in the “Principled BSDF” (Bidirectional) shader Scattering Distribution Function), which allows you to achieve realistic rendering of glass with tints or reflections like precious stones. When rendering glass, support for anisotropic roughness is also implemented, in which the blur of reflections is elongated in one direction, as on polished metal.
  
• Cycles has added support for NVIDIA’s DLSS 4.5 Ray Reconstruction noise reduction technology, which uses AI models to fill in missing details when scaling images low resolution. When previewing, using DLSS allows you to achieve quality close to the final render and remove inter-frame noise during animation. The mode is supported only with NVIDIA GPU and proprietary 620.x series drivers. Additionally, the Windows platform supports NVIDIA RTX Spark chips.
