FIELDWORK — Procedural Lab

54 native Shader Editor node groups, 20 material examples, and a studio showcase. Built for Blender 5.0+. No image textures, drivers, OSL, or runtime dependencies. All graphs are editable.

Download the complete pack · Download the add-on

Start here

Install dist/FIELDWORK-addon.zip through Edit → Preferences → Add-ons → Install from Disk, then enable FIELDWORK. In a material's Shader Editor choose Add → FIELDWORK. Nodes follow the mouse; generators arrive connected to Generated coordinates. Saved materials continue working without the add-on.

For the Asset Browser, add the dist/FIELDWORK folder under Preferences → File Paths → Asset Libraries. Drag a node group into the Shader Editor. Connect Texture Coordinate → Generated, Object, or UV to its Vector input. Asset Browser groups do not automatically insert coordinates. Keep the showcase elsewhere if you want to avoid duplicate assets; the installer folder includes the library only.

Install and enable the add-on to retain the menu after restarting Blender.

The checker tile is a reference for coordinate changes. Twist uses a tilted coordinate domain to reveal its Z-dependent rotation on a flat swatch. Spherical, cylindrical, polar, and mirror examples use centered coordinates. Tile Repeat uses a spherical gradient; the final four tiles demonstrate mask blending, contrast remapping, a palette, and surface shading. These are example settings, not the full range of each node.

Organic fields: Clouds, Flecks, Contours, Cells, Cell Edges, Pebbles, Marble, Woodgrain, Scratches, Lava.

Mapping: Coordinates, Transform, Domain Warp, Polar, Tile Repeat, Twist, Bend, Spherical Mapping, Cylindrical Mapping, Mirror, Vector Mix.

Mixing: Mask Mixer, Remap, Palette, Surface.

Patch recipes

1. Warped Voronoi: Texture Coordinate / Generated → Transform → Domain Warp → Voronoi Edges. Factor → Palette → Principled Base Color. Factor → Bump Height → Principled Normal.
2. Magic interference: Generated → Twist → Magic. Native Color → Principled Base Color. Gabor Phase → Roughness through Remap.
3. Fractured metal: Voronoi Edges Factor + Scratches Factor → Mask Mixer Union → Surface Height. Palette Color → Surface Color. Metallic 1, Roughness 0.3.
4. Truchet enamel: Generated → Truchet Arcs. Color → Surface Color; Factor → Height. Bump Distance 0.015, Roughness 0.22.

Use the Surface group's Shader output with Material Output → Surface. It wraps Principled BSDF with bump and emission controls. You can also use any ordinary Blender shader.

Controls and coordinate conventions

• Scale multiplies the input coordinates. Keep subsequent mapping scales at 1 to avoid multiplying scales unintentionally.
• Pattern groups use XY; use UV for wrapping on meshes. Generated coordinates are convenient but may stretch with object proportions.
• Transform rotations are radians. Twist rotates around Z according to Z; Bend rotates around Y according to X. These alter the texture domain, not geometry.
• Spherical/Cylindrical Mapping expect coordinates centered at the origin. Use Object coordinates, or subtract (0.5, 0.5, 0.5) from Generated first. Their seam is unavoidable; angular U occupies 0–1.
• Factor is clamped to 0–1; Raw preserves native generator values. Native Color preserves random Voronoi / Noise / Magic colors. Color is the exposed Color A/B palette.
• White Noise is discontinuous. Floor coordinates or use Tile Repeat with care when you want stable cell colors.
• Magic depth is fixed at 5 inside the group because Blender does not expose it as a linkable socket. Tab into the group to change it. Fractal fBM and Noise 4D share the same native noise algorithm; one is an explicitly named fractal entry point.
• Softness is in pattern coordinate units. Avoid extremely thin lines at distant viewing scales. Remap White Point should exceed Black Point; Flecks Upper Edge should exceed Threshold.
• The primitive Voronoi groups are 3D. Stylized Cells/Edges/Pebbles and Truchet patterns are planar. Tab into any group to change native settings such as distance metric or wave direction.
