Decal Component: Projected Surface Effects with Random Variety

The s&box Decal component draws decals in the game world. It supports multiple DecalDefinitions for random variety without extra code.

Setup

Add a Decal component to a GameObject. Define one or more DecalDefinition assets — when multiple are defined, one is chosen at random on spawn.

Randomizing Properties

Certain properties support range-based randomization. For example, set rotation to a range of 0-360 and each spawned decal picks a random angle. This creates variety and avoids visible patterns without requiring code.

Usage

Decals project onto surfaces within their volume. They're commonly used for:

• Bullet holes and impact marks
• Blood splatters
• Graffiti and environmental storytelling
• Damage indicators on surfaces

The component works well as a prefab — create a decal prefab with multiple definitions and randomized properties for reusable, varied environmental effects across your scenes.
