Please note that installation process for CLO LiveSync and MD LiveSync is identical. Only the folder names of zip folders are different (CLO LiveSync vs. MD LiveSync).
1. Install Substance 3D for Unreal Engine plugin to UE 5.4.
2. Unzip the downloaded zip folder (CLOLiveSync.zip or MDLiveSync.zip), then install LiveSync to UE 5.4 by putting CLOLiveSync folder in the following directory of your Unreal Engine installation. (default directory path: C:\Program Files\Epic Games\UE_5.4\Engine\Plugins\Marketplace) This folder is where Substance 3D for Unreal Engine plugin is located.
3. Create a new project, or open an existing project.
4. Make sure that LiveSync and Substance 3D for Unreal Engine plugin are enabled in Plugins settings.
5. In the top toolbar, go to Edit - Project Settings, then locate Platforms - Windows options to find Targeted RHIs to set its value to DirectX 11.
Please note that setting Targeted RHIs to DirectX 12 may cause unexpected graphics driver crashes in Unreal Engine 5 while using LiveSync. DirectX 11 and DirectX 12 can be used in following scenarios:
- DirectX 11: using Lumen and not using Path Tracer
-
DirectX 12: disabling Enable Order Independent Translucency (OIT), and using Path Tracer rather than Lumen
- Experimental UE5 features often require DirectX 12.
Please note that assets brought to Unreal Editor via LiveSync may not open if the setting bounces between DirectX 11 and DirectX 12.
6. In the top toolbar, go to Edit > Project Settings, and search ‘transparency’ to locate Enable Order Independent Translucency (OIT) option to enable the option.
7. Restart Unreal Editor.
8. To launch Live Sync Editor, go to Window > CLO/MD LiveSync Editor.
