@ciox If you want the dll for the Sixaxis controllers, you can get them from Steam. Open up your Steam client, then go to Library\Tools. Download the Sixense SDK for the Razer Hydra. It should contain sixense.dll, which you can bind to in an UnrealScript class. You can bind your PlayerInput for example to the dll, and then during your PlayerInput function, you can check input from sixense.dll.
Edit: Actually, looks like sixense.dll is available from the Sixense MIDI Controller tool. I used that file to make this: https://www.youtube.com/watch?v=cGmUnDTEf4w
Edit 2: Nevermind. You can get the necessary files in the SDK. It’s just in the bin folder. And you’ll want all the documentation, which is in the SDK download too.
