Subnautica does not account for this in the Mac build (and possibly also not in the Linux build). However, Unity's input manager uses different numerical axis/button mappings for Windows, Mac, and Linux. I have determined that this behaviour is specific to macOS and the cause of the problem is that Subnautica is configured to use Unity's Windows controller map on all platforms. I decided to test and research this issue myself in the hopes that it will accelerate a much-needed fix, both in the current Unity 2018.2 branch and the forthcoming Unity 2019 update. from external mice) does not fix the problem, nor does a full reinstallation. Unplugging all other USB devices and removing any interfering inputs (e.g. I personally tested this with a Nintendo Switch Pro Controller (as supported in Steam), but from extensive searching, the symptoms match bug reports from other Mac users using Xbox or Xinput gamepads.Īs reported by others, this issue occurs for me only in Subnautica and cannot be reproduced with the same controller configuration anywhere else in my Steam library. Many other button mappings are incorrect: for example, pressing RT on the controller inputs right on the D-pad. Right-stick X-axis produces an input of the triggers (left -> LT, right -> RT). Right-stick Y-axis (up/down) produces an input of the right-stick X-axis (right/left). This is an issue that has been repeatedly reported in this support forum and elsewhere since 2017 (examples here, here, here, here), and has still not been fixed as of the Big Little Update.
