Outline & Highlight FX is a collection of 12 post process materials for Unreal Engine 5 that let you add enemy outlines, stealth vision overlays, focus mode highlights, and animated scan effects to any object in your game — using UE5’s Custom Depth pipeline, no C++ required.

Drop the material into your Post Process Volume, assign Custom Depth to your target actors, and the effect is live. Every material is fully parameterized: outline thickness, color, animation speed, and intensity are all exposed as scalar/vector parameters.

What’s included:

• Outline effects — standard and animated outline (Custom Depth edge detection)

• Overlay effects — multiplier, cell noise, Perlin 3D, curl noise, gradient noise, normal multiplier (static and animated), horizontal/vertical/HV animated stripes

• 12 materials total — each with up to 256 color variations via parameter, giving 3,072+ distinct effect states out of the box

Perfect for:

• Enemy tagging mechanics — see targets through walls (Splinter Cell / AC Origins style)

• Eagle vision / detective vision modes

• Stealth overlay and threat detection UI

• Focus mode ability effects

• Scan pulse and ping effects

• Any gameplay system that needs to visually distinguish objects at runtime

Getting started:

1. Add the asset to your project via the Fab Library

2. Enable Custom Depth on target actors (Details panel → Render → Custom Depth Stencil Pass)

3. Add a Post Process Volume to your level (or use an existing camera PPV)

4. Assign the desired M_PP_* material to the Post Process Volume’s material slot

5. Adjust Intensity, Color, and Thickness parameters to match your game’s visual style

Technical:

• 12 unique post process materials, all Blueprint-accessible via parameter collections

• Up to 256 color variations per material via Vector Parameter

• No C++ required — pure material-based implementation

• Compatible with UE5’s Lumen and traditional rendering paths

• Supported platforms: Windows, Mac, Linux
