Outline Component

The Outline component adds an animated, customizable outline effect to any GameObject with a Mesh.

Features

• Outline color supports HDR (glow with Bloom)
• Optional animated gradient color via AnimationCurve
• Option to pre-bake smooth normals for performance
• Multiple outline modes including silhouette-only and visible-only
• Automatically adds necessary materials at runtime

🛠 Usage

Basic Setup

Add the Outline component to a GameObject. It will automatically:

• Detect child renderers
• Add outline materials at runtime
• Apply default outline color and width

Outline Modes

Control how the outline is rendered:

Mode	Description
OutlineAll	Always visible, even through walls
OutlineVisible	Only visible when the object is visible
OutlineHidden	Only visible when the object is behind something
OutlineAndSilhouette	Visible and includes silhouette outline
SilhouetteOnly	Only renders silhouette, not full outline

Animated Gradient

1. Set Color Type to Gradient
2. Assign a Gradient
3. Define an AnimationCurve (typically goes from 0 to 1)
4. Set the end node of the AnimationCurve to loop or ping pong to run indefinetily
5. Adjust Animation Speed

Bloom Post-processing is recommended for glowing outlines with HDR colors.

Smooth Normals Baking (Optional)

For improved performance:

• Enable Precompute Outline in the Inspector
• Smooth normals will be baked in the editor

If disabled, smooth normals are calculated at runtime on Awake() (may cause lag on large meshes).
