VFXWeaver API
by Artition
VFXWeaver API is a client-side Java library that gives other mods cinematic effects such as screen post-processing, camera shake and block or entity overlays.
What it does
The library covers camera effects with simplex-noise shake, a smooth envelope, a dutch-angle roll and a field-of-view modifier. World overlays add block tint, block outlines, world-space geometry, a light beam with a soft vertical column and a pulse ring. Entity effects cover entity tint, outlines and displacement, with per-vertex displaced echo.
Effects can also be defined in datapacks as plain JSON, and keyframe animation supports easing curves, world, camera and player bindings, math expressions and sounds. Animated parameters can read player state such as vitals, movement speed, the light around the player, the clock and position. A static entry point, dev.vfxweaver.api.VFXAPI, lets other mods call the library with a one-liner per call.
The library requires Fabric API on Fabric and is published for Fabric and NeoForge. Players need the mod on their client, while the server may skip it and still add extra features. The mod is released under the MIT License, and it is open source.
Key features
Camera effects
Simplex-noise shake, a smooth envelope, a dutch-angle roll and a field-of-view modifier shape the camera.
World and entity overlays
Block tint, block outlines, light beams, pulse rings and entity outlines and tints are drawn in world space.
Keyframe animation
Easing curves and math expressions bind to world, camera and player values, with a progress parameter from 0 to 1.
Datapacks and commands
Effects defined in plain JSON can be fired by a server command, and a public Java API lets other mods trigger them.

Use cases
Who it’s for: Mod developers who want to add effects without writing rendering code, and datapack or map authors who want effects triggered by player state or server commands.
How it compares
Camera Shakify is client-side only, uses Fabric alone and is licensed under All rights reserved, so it is not open source. Handycam is client-side only and is open source under the GNU Lesser General Public License v3.0 only, with files for 1.20.1 – 26.2. Lumiera covers Fabric, Forge and NeoForge for 1.20.1 – 26.1.2 under a custom license, and either side can run it, and neither needs it.
