So after a little headache I was able to get my DualShock4 controller to work with ESO (using Input Mapper). I am not using any other 3rd party programs, all IM does is make my DS4 controller look like a Xbox controller. Right now everything is working in game except I need the Y-Axis to be inverted. After a lot of searching I finally found the camera tab and the Invert Y axis setting however it is only applying to my mouse and not the controller.
So my mouse Y Axis is inverted but the controller isn't. Can anyone help me out here?!? Is there some setting in some config file that I can change to get my controller Y Axis to be inverted. I need it to be the Right joystick on my controller.
