FXMaster+ is a premium expansion module for FXMaster, adding new particle and filter effects for Foundry VTT. FXMaster+ provides ready‑made ambience for your scenes — and tools for building your own.
Requires: FXMaster
Patreon subscribers get access to a monthly vote to determine new effects!
New Effect Highlights:
- Water — a brand new filter effect that renders procedural, animated water across the scene, from calm pools to flowing channels and swirling vortices.
- Motion layers: Flow, Waves, and/or Vortex, with independent speed and strength controls, directional flow/waves, and clockwise or counter‑clockwise vortex spin
- Fully tweakable surface look: tint, opacity, scale, turbulence, refraction, caustics, caustic strength, and caustics tint
- Still water controllable animation speed for calmer surfaces
- Region‑aware flow: optionally follow a Region path with adjustable path influence for rivers, streams, and channels
FXMaster+ currently includes a number of built‑in effects detailed below, along with the ability to create your own template‑based Particle Effects and manage scene/region sound effects tied to FXMaster effects.
Built‑in Effects:
- Particle Effects
- Sakura Bloom — Sakura petals blowing across the screen
- Sakura Blossom — Sakura petals drifting randomly across the screen
- Magic Crystals — shimmering magic crystals emanating from a centered position, with adjustable spin, glow, and bloom
- Fireflies — wandering fireflies with periodic glow
- Ghosts — spectral drift with adjustable sprites, blur, displacement, glow, and wobble
- Sandstorm — wind‑swept grains of sand
- Fish — Betta, Koi, and Manta Ray fish with numerous sub‑types
- Filter Effects
- Water — You know it, you love it, H2O!
- Lightning Bolts — procedural bolt streaks (horizontal and/or top‑down strikes) with optional synced flash
- Ice — thick ice sheet with reflection, sheen, underlayer water, and many other tweakable options
- Sunlight — warm beams of sunlight with subtle haze, parallel or radial emanation, and adjustable intensity/volume/length
- Duststorm — multi‑layered sheets of dust with many configuration options
- Glitch — distortion effect with an optional matrix‑style glyph sheet
Sound Effects Manager (Foundry V13+)

FXMaster+ includes a Sound Effects Manager tool that lets you tie sounds to FXMaster / FXMaster+ effects — perfect for adding thunder, wind, insects, etc.
- Rule‑based: create multiple sound rules and enable/disable them at will
- Pick effects: each rule can listen to one or more particle/filter effects
- Multiple sounds per rule:
- Parallel mode (layer sounds together)
- Sequential mode (cycle through sounds)
- Mix controls: per‑sound level, drag‑to‑reorder priority, and configurable fade time
- Optional: pause playlists while a rule is active
- Region audio options: when using effects via Regions, you can constrain/shape how the sound behaves (scene, region‑only, region padding, or point‑source style) with optional easing and wall interaction
Where to find it: Scene Controls → FXMaster Effects → Manage Sound Effects (speaker icon)
User Particle Effects Manager

Create your own custom particle templates using your own sprites, then use them like any other FXMaster particle effect!
- Template bases: build on a Directional Drift or Ambient Float style base
- Bring your own sprites: provide one or more texture paths (multiple textures are randomized)
- Organize cleanly: choose a group (Weather / Ambient / Animals) and set a custom icon
- Works with FXMaster workflows: activate globally from the Particle Effects UI, or apply via Regions (just like built‑ins)
Where to find it: Scene Controls → FXMaster Effects → Manage User Particle Effects (plus icon)
