Please post questions about Rewired on the Rewired support thread or use the support form on the webiste. I do not scour the Unity forums for questions about Rewired. I was made aware of this message by a user of Rewired.
The answer to your question is, map the same UI vertical and UI horizontal Actions that you specified in the Rewired Standalone Input Module to the D-Pad buttons. That’s it.
