All Platform Outline Pack


All platform outline pack is a material + blueprint pack to enable drawing outlines of static and skeletal meshes on all UE4-supported platform (mobile, desktop, VR, console, etc).

The implementation does not use post-processing but automatically duplicates and appropriately enlarges the given mesh to draw its outline. This is a traditional offset-based outline drawing, which unfortunately has several difficulties to be implemented in UE4. This pack solved those technical issues and provides a simple workflow to draw outlines of objects, which is just simply adding a provided actor component blueprint to a mesh. Truly, that is all that users need to know to draw outlines whatever their platform is. Our implementation also supports line width, color and opacity customization, which can be done by changing material in the actor component’s material slot.

Currently the outlines are only drawn in play mode. It remains our future work to see the outlines in the editor, which may require some new functionalities of blueprint actor components.

Key features of this pack includes:

  • all platform support (i.e., iOS, Android, Windows, Mac, Linux, HTML5, Consoles, and VR devices)
  • no need to generate normal-inverted meshes by yourself
  • no need to manually duplicate a mesh and handle it in the scene
  • two types of line-width control (screen-space and world-space)
  • support for both static and skeletal meshes
  • fully customizable line width, color, and opacity

Any new features/bug fixes for since 4.17?
For some meshes the outline does not look too good.

Hi Melnik,

Sorry for the delayed response.
We have finished the initial implementation to handle such meshes.
Here is the result.

We requested your model by private message. Once we check the implementation works with yours too, we will update the pack with this new feature.

Thank you for your great report and feedback.


Thank you for working on it!
