Unfortunately, it’s not possible to make it compatible with Unreal Engine 5.4. All .uasset files were created in 5.5, and assets created in a newer version of Unreal Engine are not backward compatible. You can only upgrade assets to a higher version, not downgrade them.
As a possible workaround, you could try obtaining the plugin for 5.5 and then copying it into your project. The C++ code should work fine, but you’ll need to manually recreate the Blueprint assets and copy the logic from the 5.5 version. However, I can’t guarantee that it will work correctly.
