Godot 4.2 Adds AnimationMixer and 2D Navigation Baking

A polished follow-up

Godot 4.2 was released on November 30, 2023. Over the previous five months, 359 contributors submitted more than 1,800 improvements, mixing bug fixes with new features to make Godot 4 a more polished tool. It followed 4.1's cadence of a feature release roughly every four to five months.

AnimationMixer and onion skinning

The biggest change was an internal rework of AnimationPlayer and AnimationTree, unifying parts of their implementation under a new AnimationMixer intermediate node to bring the two to feature and behavior parity, along with a new deterministic blending option. Onion skinning also returned: originally built for Godot 3.0 and disabled in Godot 4, it lets animators preview preceding and upcoming frames as a red/green semi-transparent overlay.

Navigation and 2D features

Navigation maintainer smix8 added navigation mesh baking for 2D, bringing it to parity with 3D and handling physics bodies, mesh instances, plain polygons and tilemaps, while both 2D and 3D navigation servers gained multithreaded baking to remove stutters. For 2D games, 4.2 added forced integer scaling for a distortion-free pixel grid and a closed property for Line2D nodes.

Core, tilemaps and the editor

The core team focused on stability, fixing crashes and scene-file corruption around changing scenes and renaming or moving files to make 4.2 far more version-control friendly, and added runtime loading of OGG and SVG files from buffers. Tilemaps received major performance optimizations and a tool to flip and rotate tiles when placing them, and the code editor gained foldable, named code regions for GDScript.
