description	Generate textures for ZX 3D meshes using Python + NumPy + FastNoiseLite. Triggers: "generate texture", "procedural texture", "noise pattern", "MRE texture", "albedo", "matcap", "seamless texture". Before generating: Check `.studio/visual-style.md` for project style specs.

version	2.3.0

Procedural Texture Generation

Generate game-ready textures using Python with Pillow, NumPy, and FastNoiseLite.

pip install pillow numpy pyfastnoiselite

Output Requirements

Format: PNG (RGBA or RGB)
Resolution: Power of 2 (64, 128, 256, 512 max)
Aesthetic: Low Poly / N64 / PS1 / PS2 era

Render Mode Quick Reference

Mode	Maps	Use Case
0	Albedo	UI, sprites, flat-shaded
1	Albedo + Matcaps	Stylized toon
2	Albedo + MRE	Modern PBR
3	Albedo + SSE + Specular	Retro PS1/N64

See references/render-modes.md for complete mode documentation.

Quick Start

Create a texture spec under .studio/specs/textures/ and run the unified generator.

Noise Algorithms

Algorithm	Best For
Perlin	Smooth organic patterns
Simplex	Faster Perlin, fewer artifacts
Cellular	Cells, cracks, scales
Value	Hard-edged noise
Fractal FBM	Complex organic detail

See references/noise-algorithms.md for complete reference.

Multi-Layer Composition

1. BASE: Solid color + subtle noise
2. DETAIL: Perlin/Simplex overlay
3. FEATURES: Scratches, cracks, grain
4. WEATHERING: Rust, stains, dust
5. FINAL: Contrast, color grading

See references/layer-system.md for layer system details.

Spec-Based Workflow

Create .spec.py files for deterministic generation:

TEXTURE = {
    "texture": {
        "name": "wood_plank",
        "size": [256, 256],
        "layers": [
            {"type": "solid", "color": 0.5},
            {"type": "wood_grain", "ring_count": 12, "blend": "multiply"},
            {"type": "noise", "noise_type": "perlin", "scale": 0.15, "opacity": 0.3}
        ],
        "color_ramp": ["#4A3728", "#6B4423", "#8B4513"]
    }
}

Run: python .studio/generate.py --only textures

Layer types: solid, noise, gradient, wood_grain, brick, checkerboard, stripes Blend modes: normal, multiply, add, screen, overlay, soft_light

Console Constraints

Constraint	Limit
Max resolution	512 x 512
Sizes	Power of 2
VRAM budget	4MB total
