VFX Sheet Baker - Godot 4 Particles and Shaders to Sprite Sheet

Bake 2D effects into sprite sheets with real alpha, inside the Godot 4 editor

VFX Sheet Baker turns a particle, shader or animation scene into a sprite sheet PNG, a SpriteFrames resource and JSON metadata, from a dock in the editor.

Making a 2D game in Godot? The Godot 2D Bundle has 7 of our Godot 4 packs (2 starter templates, Stylized 2D VFX, Sprite Juice Kit, Screen Transitions, Scanline Stack, VFX Sheet Baker) for $14.99 instead of $41.45 bought one by one, until November 9.

Try before you buy: download the free Lite version (up to 16 frames, PNG sheet).

What it does

• A dock in the Godot editor: pick a 2D effect scene, set frame size, frames, FPS, columns, warm-up, press Bake sheet.
• Works with GPUParticles2D, CPUParticles2D, AnimatedSprite2D, AnimationPlayer (autoplay) and shaders that use TIME.
• Real transparency: frames are read from a transparent viewport; straight alpha PNG by default, premultiplied as an option.
• Outputs: PNG sheet, SpriteFrames .tres ready for AnimatedSprite2D, JSON metadata (frame rects, fps) for other engines, optional single frame PNGs. Up to 512 frames.
• Repeatable: the bake runs with a fixed time step and fixed particle seeds, so the same settings give the same bytes (tested twice per demo effect on Godot 4.4.1).
• Pixel scale: nearest-neighbour downscale for a pixel-art look. Loop blend: cross-fades extra frames into the start for seamless loops.
• Clear messages: missing scene, nothing visible, effect cut off by the frame border, bake process failed.
• Command-line entry for build scripts (same code path as the dock).

What is inside

• The addon (addons/vfx_sheet_baker) with the dock, the bake runner and the command-line entry.
• A demo project with 3 effect scenes made by our own code: a GPUParticles2D fire burst with an AnimationPlayer flash, a shader portal ring using TIME, a CPUParticles2D sparkle.
• README.txt (settings, messages, use in Unity / GameMaker) and LICENSE.txt.

Requirements

• Godot 4.4 or newer, tested on Godot 4.4.1 (Windows 10, Forward+ and Compatibility). 2D effects only.
• A small bake window opens for a few seconds while the frames render.
