Real-time procedural camouflage and texture generator with two implementations:
- Web App (
index.html) - Browser-based real-time generator with interactive controls - DaVinci Resolve Fusion Fuse (
MARPATCamo.fuse) - Native Fusion plugin for video production
Both generate MARPAT-style digital camouflage, MultiCam-style organic patterns, and a wide range of artistic texture presets using fractal Brownian motion (fBm) over simplex noise.

- Real-time rendering at 60-120fps using Canvas 2D with Uint32Array pixel writes
- 20+ presets spanning military camouflage, cinematic textures, and artistic palettes
- Two rendering modes:
- Digital (MARPAT) - Pixelated rectangular cells with hard color thresholds
- Organic (MultiCam) - 3-layer architecture with smooth gradient blending, organic blobs, and micro-texture
- Zoom & pan - Scroll to zoom (toward cursor), drag to pan. Wobble-free integer screen-space grid mapping
- Animation - Directional scrolling with speed/direction controls
- Seethe - Cyclical in-place pattern evolution via domain warping (no translation). Threshold shifting creates organic "breathing" motion
- Screen Pixels mode - Pixel size stays constant on screen regardless of zoom
- Effects - Static domain warp, contrast adjustment, color inversion
- Per-color controls - Individual color pickers and weight sliders for each palette color
- Export - Save current view as PNG or generate a 512x512 tile

- Zoom-adaptive coarsening - Grid cells merge when sub-pixel, maintaining consistent performance at any zoom level
- Coarse gradient grid - MultiCam background gradient computed at 1/8 resolution with bilinear interpolation
- Reduced octaves at zoom-out - Detail noise octaves decrease when zoomed out (invisible detail is not computed)
- Uint32Array pixel writes - 4x fewer array operations vs byte-by-byte writes
- Integer screen-space mapping - Eliminates floating-point wobble artifacts during animation
- Grid-cell noise caching - Noise computed once per grid cell, not per screen pixel
Copy the fuse file to the Fusion Fuses directory:
macOS:
cp MARPATCamo.fuse ~/Library/Application\ Support/Blackmagic\ Design/DaVinci\ Resolve/Fusion/Fuses/
Windows:
Copy MARPATCamo.fuse to: %AppData%\Blackmagic Design\DaVinci Resolve\Support\Fusion\Fuses\Linux:
cp MARPATCamo.fuse ~/.fusion/BlackmagicDesign/DaVinci\ Resolve/Fusion/Fuses/
Restart DaVinci Resolve
In the Fusion page, right-click the node editor and select Add Tool > Generator > MARPAT Camo
The Fusion Fuse uses Lua-based CPU rendering (per-pixel SetPixel loops). Performance is highly dependent on Pixel Size:
- Pixel Size 8+: Smooth interactive preview at 1080p
- Pixel Size 4-6: Usable for preview, slight lag
- Pixel Size 1-3: Slow for interactive work, best reserved for final render
- Organic (MultiCam) mode: More computationally intensive than Digital mode due to 3-layer blending and additional noise evaluations
For interactive editing, work at a higher pixel size and reduce it for the final render. Frame caching means static frames render only once.
The web app achieves significantly better performance because it uses optimized JavaScript with Uint32Array writes and runs in the browser's highly optimized Canvas pipeline.
- 21 presets: Woodland, Desert, Snow, Urban, Night, Noir, Smoke, Parchment, Moss, Concrete, Dusk, Cyberpunk, Autumn, Ocean, Lava, Pastel, Film Grain, MultiCam, MC Arid, MC Tropic, MLST, Custom
- Two rendering modes: Digital (MARPAT) and Organic (MultiCam)
- 6 color pickers with weights - All presets prefill the pickers; customize any color after selecting a preset
- All parameters keyframeable - Animate any parameter over time in the Fusion spline editor
- Seethe animation - Keyframe the Seethe control linearly for continuous in-place pattern evolution. The value acts as a rate: constant value = continuous evolution, 0 = frozen
- X/Y/Z Offsets - Translate the pattern (keyframe for scrolling animation). Z offset morphs through 3D noise space
- Zoom - Scale the pattern view
- Warp - Static fbm domain warping for organic flowing shapes
- Contrast - Sharpen or soften color transitions
- Invert - Flip the noise mapping
- Frame caching - Automatically skips re-rendering when no parameters have changed between frames
- Grid-cell caching - Noise computed per grid cell, not per pixel (significant speedup)
- Coarse gradient grid - Organic mode computes background at 1/16 resolution with bilinear interpolation

- Animating the pattern: Keyframe X/Y Offset for scrolling, or keyframe Seethe for in-place evolution
- Best performance: Use Pixel Size 4+ for interactive preview; reduce for final render
- Color matching: Colors are written in the project's working color space. If colors look different in Edit vs Fusion, ensure your project's Color Space settings are consistent
- Organic mode: More computationally intensive due to 3-layer blending. Use larger pixel sizes for interactive work
- Custom colors: Select any preset to load its palette into the color pickers, then modify individual colors
Both implementations use the same core algorithm:
- Simplex noise with seeded permutation tables for deterministic output
- Fractal Brownian motion (fBm) - Multiple octaves of noise summed with decreasing amplitude and increasing frequency
- Dual noise layers - Primary noise for large-scale structure, secondary noise at 2.7x frequency for additional detail
- Color quantization - Noise values mapped to discrete color bands via weighted cumulative thresholds
Based on research into Crye Precision's MultiCam design and the Dutch NFP fractal method:
- Background gradient (Layer 1) - Very low-frequency noise (0.15x scale) creates smooth regional color transitions. Two adjacent palette colors are interpolated based on noise value, creating the "color-shifting" effect that makes MultiCam appear to change hue regionally
- Mid-frequency organic blobs (Layer 2) - Standard fBm noise provides macro-scale disruption shapes. Composited onto the gradient with variable opacity: hard edges deep inside color bands, fading edges near thresholds
- High-frequency micro-texture (Layer 3) - Fine-grain detail from the secondary noise layer. Adds subtle per-channel RGB variation for close-range disruption
Unlike simple translation, seethe creates cyclical in-place evolution:
- Domain warping:
sin(position + phase)andcos(position + phase * 0.7)distort noise coordinates in a position-dependent way. Each cell gets a unique warp, so the pattern morphs organically without sliding - Threshold shifting: Sinusoidal modulation of color band boundaries causes colors to ebb and flow cyclically
- No scale modulation: Pattern scale remains constant (no zoom/breathing)
