  • One-Click Precision Streamlined, one-click operations for fast decal placement on any geometry.

  • 4K Decal Pack (240+) Includes a high-quality library of tileable, seamless edge decals optimized for performance and next-gen visuals.

  • Intuitive UI & Shortcuts Designed with artists and level designers in mind. Decals snap and align with minimal input, maximizing workflow efficiency.

  • Optimized for Performance Lightweight decals and efficient blueprint systems ensure minimal performance overhead in real-time projects.

Please note that the orientation of the decal is based on the normal of the surface you are clicking on.

This plugin requires the "ScriptableToolsFramework", "ScriptableToolsEditorMode" & "GeometryScripting" plugins to be on, but no worries, they are included and active with your Unreal Engine by default!

Please note that this tool uses the collision geometry as a placeholder to find all the vertex and edges of the assets, if there is no collission geometry, please, change the "collision complexity" from your target geometry to "Use Complex Collision As Simple".

How to use Edge Decal Studio

To use Edge Decal Studio, there are a few things to keep in mind regarding required plugins and activation steps. The good news? Everything is automatic and built into Unreal Engine.

Edge Decal Studio depends on the following Unreal Engine plugins:

  • Scriptable Tools Framework

  • Scriptable Tools Editor Mode

  • Geometry Scripting

These plugins are included by default in Unreal Engine and are automatically enabled when you install EDS via Fab. No manual setup is required.

To launch and use the tool inside Unreal Engine:

  1. Change the Selection Mode to Scriptable Tools.

    • You can do this from the top toolbar by clicking the Selection Mode dropdown and choosing Scriptable Tools.

    • Or use the shortcut: Shift + 9.

  2. Once you're in Scriptable Tools Mode, you’ll see the Edge Decal Studio interface appear in the editor.

  3. From there, you can start placing decals directly along mesh edges using snapping, shortest path detection, and other built-in alignment tools.
