\"\"<\/p>\n

Blender, the popular 3D computer creation software, released new 5.3 verison yesterday.<\/p>\n

The new version of this free open-source software introduces an optional project system. It makes Blender aware of a larger context<\/b>, rather than just the currently open blend file.<\/p>\n

Each project has a root directory, and all files under that directory are considered part of the project.<\/p>\n

<\/p>\n

\"\"<\/a><\/p>\n

Blender 5.3 adds a new operator in the Animation tab of the 3D Viewport, allowing to copy and past world-space animation, and, it supports multiple selected objects or bones.<\/p>\n

It also adds a new operator, anim.rotation_mode_convert<\/code>, as a replacement of the deprecated Rigify pose.convert_rotation<\/code>, to convert animation between rotation modes.<\/p>\n

The extension system now supports Asset Libraries<\/b>. User can now install asset libraries from an Extensions Repository, along with the Add-ons and Themes.<\/p>\n

Remote Asset Libraries supports access token authentication. And, assets in online\/remote libraries can now be ‘replaced’ with versions for newer Blender releases.<\/p>\n

Compositor now lets users apply multiple visual effects in a stack<\/b>, one after another, similar to how Geometry Nodes modifiers are organized. And, the interactive compositor now supports playback caching , with playback up to 2x faster on GPU.<\/p>\n

\"\"<\/p>\n

The Principled BSDF now supports Dispersion, which can be used to render glass or diamonds that split white light into rainbow colors.<\/p>\n

Roughness anisotropy is now supported by the Glass BSDF and the transmission component of the Principled BSDF, which works the same as the roughness anisotropy for the specular reflection.<\/p>\n

On NVIDIA GPUs with 620 ow newer driver, the viewport now features a new DLSS denoiser. It provides a cleaner image faster through upscaling and reusing samples from previous frames.<\/p>\n

Blender 5.3 also introduces new low level Construct Curves node for building curves with a custom topology, a few new volume grid nodes, and new input nodes for accessing built-in attributes for NURBS curves.<\/p>\n
