APVPainter is a high-performance procedural vertex color generation plugin for Unreal Engine, designed to create natural variation, weathering effects, and ambient occlusion directly in vertex colors — without requiring external textures or manual painting.

It focuses on noise-based procedural generation with triplanar projection and ray-traced ambient occlusion — delivering fast, automatic vertex color painting with independent per-channel control for complex material setups. Perfect for environment art, prop creation, procedural workflows, or any project requiring automated vertex color generation—where surface variation should feel natural, consistent, and data-driven.

Core APVPainter features:

PROCEDURAL NOISE GENERATION:

• Five noise algorithms — Perlin, Simplex, Worley (Cellular), Voronoi, and White Noise

• Fractal layering with octaves (1-8) — combine noise layers for rich, detailed patterns

• Lacunarity & Persistence control — fine-tune frequency and amplitude per octave

• Scale & World Scale parameters — match real-world dimensions and pattern density

• Intensity & Offset per channel — precise output control for each color component

INDEPENDENT CHANNEL CONTROL (R, G, B, A):

• Per-channel noise configuration — different noise type, scale, and settings for each channel

• Multi-purpose material data — store roughness, metallic, AO, and detail masks in separate channels

• Enable/disable channels individually — paint only the channels you need

• Custom output mapping — intensity and offset for precise value ranges

TRIPLANAR PROJECTION:

• UV-free painting — works on any mesh, even without proper UV unwrapping

• Three-axis projection — eliminates stretching on complex geometry

• Blend sharpness control (1-32) — adjust transition smoothness between projection planes

• World/Local space modes — consistent patterns across meshes or unique per-mesh variation

AMBIENT OCCLUSION:

• Ray-traced contact shadows — hemisphere sampling for accurate vertex-based AO

• Configurable sample count (4-64) — balance quality vs processing time

• Distance control (0.1-1000) — adjust occlusion radius to match mesh scale

• Intensity multiplier (0-2) — fine-tune shadow strength

• Invert option — reverse occlusion values for special effects

Flexible Workflow:

• Editor Window — visual interface with real-time mesh selection

• One-click application — instant vertex color generation

• Clear & Refresh buttons — reset colors or reload mesh

• Undo/Redo support — iterative painting workflow

• Per-mesh configuration — customize settings for each asset

Performance & Optimization:

• Fast processing — optimized C++ implementation with multi-threading

• Scalable quality — adjust octaves and AO samples for performance

• Editor-only tool — baked vertex colors at edit time, zero runtime cost

• Memory efficient — processes LOD0 only, minimal memory overhead
