Easy Paint 3D

Easy Paint 3D is an extensible runtime surface painting toolkit designed for Unity 2022 and later.

The package allows developers to paint directly onto supported 3D surfaces during gameplay. Each paintable object receives its own configurable runtime paint texture, allowing colors, trails, splashes, collision marks, dirt, damage, territory masks and similar effects to remain visible on the surface.

Easy Paint 3D uses a modular architecture built around PaintingSystem, PaintSurface, PainterBase and reusable PaintBrushPreset assets. Different painting components inherit from the same base system, making it easy to select the most suitable interaction method without replacing the core painting engine.

Included painting methods:

• Mouse-based surface painting

• Touch-based mobile painting with PC and Editor mouse fallback

• Object trail painting

• Collision and contact painting

• Ray-based painting

• Sphere-cast painting

• Standard Particle System paint spray effect

Brush presets provide configurable color, opacity, shape, diameter, hardness, spacing and blend mode settings. The package includes Replace, Alpha Blend, Additive, Multiply, Maximum, Minimum and Erase operations.

Each PaintSurface supports configurable texture resolution, initial color, filtering, coordinate mode, Undo, Redo, Clear and PNG export operations.

The package includes three example scenes:

• Mouse Painter

• Object Trail

• Physics

Four ready-to-use color presets, example materials, prefabs, 512 × 512 textures, a paint spray particle effect and a daylight skybox are also included.

Easy Paint 3D is suitable for painting games, cleaning games, graffiti systems, vehicle tracks, footprints, projectile impacts, paint guns, dirt and damage masks, territory mechanics, interactive demonstrations and stylized gameplay effects.

The included shaders contain dedicated implementations for the Built-in Render Pipeline, Universal Render Pipeline and High Definition Render Pipeline.
