Hi, I can't tell you if there is an obvious problem because I don't have enough information about how you've set things up. First, you will have to verify things are working with Rewired alone. I can't help you with Otii's Motion Controller as I don't have any experience with that. Please try one of the example scenes such as EightPlayers and see if the controller works. If it does, then you've either done something wrong in the basic setup, so restart at the Quick Start, or there may be an issue or setup required with Otii's integration (choose a source Player?). If nothing works in the EightPlayer demo, create a new scene, add the Rewired/DevTools/JoystickElementIdentifier to the scene and create an empty Rewired Input Manager. Press Play and see if anything joysticks show up in the left column. If you have multiple joysticks attached to the system, remove all but the DS4 because this could be the problem.
