Resolume ISF Shaders

Custom ISF (Interactive Shader Format) shaders compiled as FFGL plugins for Resolume Arena.

Each effect lives in its own folder with the .fs source and compiled .bundle.

Effects

Shader	Description
AquarelaMask	Watercolor paint effect with Kuwahara smoothing and gradient mask
BlurMask	Gaussian blur with gradient mask control
EdgeGrow	Organic lichen-like growth extending from edges of source shapes
EnergyPulse	Expanding pulse that illuminates shapes as it sweeps through
GhostTrail	Ethereal ghost copies drifting from source shapes
GradientAlpha	Gradient-based alpha control
InstaCrop	Centered pixel crop with black letterbox — set visible area in pixels (e.g. 1080×1440)
PulseRings	Concentric rings rippling outward from shape edges
ShapeGen	Graphic score generator with 3 tracks of organic shapes
SlitScreen	Repeats boundary pixels outward from a gradient mask edge
SmartVignette	Vignette with round/square modes, movable center, optional image mask
SmokeDissipation	Content wisps away like rising smoke with curl noise turbulence
WarpFBM	Domain-warped FBM that organically warps source content with animated noise

Most effects share a common gradient mask system: maskPos, maskWidth, fadeWidth, angle, radial, invert.

Compiling ISF to FFGL

Shaders must be compiled into .bundle FFGL plugins for Resolume to load them. This uses ffgl-rs.

Prerequisites

• Rust: curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
• Xcode CLI tools: xcode-select --install
• ffgl-rs repo: cloned at ~/Documents/GitHub/ffgl-rs

Compile a single shader

cd ~/Documents/GitHub/ffgl-rs
bash ffgl-isf/deploy_isf.sh /path/to/ShaderName/ShaderName.fs

This compiles the ISF shader and deploys the .bundle to:

• ~/Documents/Resolume Arena/Extra Effects/
• ~/Library/Graphics/FreeFrame Plug-Ins/

Compile all shaders

cd ~/Documents/GitHub/ffgl-rs
for f in ~/Documents/GitHub/resolume-ffgl/*/*.fs; do
  bash ffgl-isf/deploy_isf.sh "$f"
done

After compiling

Restart Resolume Arena to pick up new/updated effects.
