Hi,
this plugin officially only supports Windows and Android platforms, since they’re the only ones that I can test and verify that everything works. You can make it run on other platforms too (like Mac), but you have to compile the plugin yourself. I’ve heard from many users that it works just fine.
In order to compile the plugin, you need to download the source code from GitHub, and copy the plugin into your project. After that edit the “NiagaraUIRenderer.uplugin” file. Add your desired platforms into the “SupportedTargetPlatforms” and “PlatformAllowList” arrays, and recompile the project (for Mac / iOS from xcode).
If your project is blueprint only you need to do this compilation in a second C++ project.
(Optional if your project includes C++, required if it’s Blueprint only)
After you have the project running (on Mac), go into the plugins window, click “Package” under the Niagara UI Renderer plugin, and select a target empty folder. This will compile all the versions of the plugin, and will create a plugin folder that you can use in your project. This will eliminate the need for everyone to download the plugin separately and will work on all the platforms.
Hopefully this helps.
Cheers!
