Godot 4.0 Release: Major 3D, 2D, and Rendering Overhauls Unveiled

3D and General Rendering Changes

Vulkan and New Renderer

Godot 4 introduces two new Vulkan back‑ends (cluster and mobile) and integrates an OpenGL compatibility renderer for legacy and low‑end devices. Direct3D 12 support is in development, and AMD FidelityFX Super Resolution 1.0 is available for high‑quality rendering at lower resolutions.

Highly Improved Lighting and Shadows

Godot’s global illumination system has been rebuilt from scratch. The new Signed Distance Field Global Illumination (SDFGI) brings real‑time GI to large open worlds. VoxelGI replaces GIProbe for midsize environments, while lightmaps now render on the GPU for faster performance.

Shadow rendering has been overhauled to provide higher quality and finer control.

New Rendering Optimizations

Automatic occlusion culling removes hidden geometry at runtime, improving CPU and GPU performance. In open environments, automatic mesh LOD or manual HLOD can be used to control visible ranges.

Enhanced Post‑Processing

Screen‑Space Indirect Lighting (SSIL) and a powerful SSAO implementation allow fine‑tuned ambient occlusion and indirect lighting. Physical light units enable realistic camera settings such as aperture, shutter speed, and ISO.

2D Improvements

Powerful New 2D Tilemap Editor

The redesigned tilemap editor unifies tileset and tilemap workflows, adds layers, terrain auto‑tiling, random placement tools, and selection tools for reuse. Tileset textures auto‑expand to prevent gaps, and new scene placement lets you add characters, boxes, and other interactive scenes directly on the grid.

New 2D Rendering Options

The 2D canvas renderer now supports complex blending of overlapping CanvasItems, Clip Children masking, and Multi‑Sample Anti‑Aliasing (MSAA) for smoother edges.

Improved 2D Lighting and Shadows

2D directional lights and shadows have been enhanced, with signed distance field shaders enabling long shadows, halos, and crisp outlines.

Shaders and Visual Effects

New Atmospheric Effects

Volumetric fog with temporal reprojection, configurable FogVolume nodes, and a sky shader for dynamic skies with reflections are introduced.

Texture and Material Projection

Decals allow materials to be projected onto surfaces, and new noise textures have been back‑ported from Godot 3.5.

Enhanced Shader Editor

GPU‑based particles now support attraction, collision, trails, sub‑emitters, and manual emission. Global shader parameters can be shared across materials for effects like wind or humidity.

Extended Shader Language

Support for uniform arrays, fragment‑to‑light variations, structures, preprocessor macros, and shader includes has been added.

Compute Shaders

Godot now supports compute shaders to accelerate GPU‑based algorithms.
