Look with mouse.

Just started playing again, and I'm having an issue with look controls. I can't use my mouse to look at all, nor can I map the binds to my mouse (I select a look axis and move my mouse to bind it, but nothing happens).

I'm using a Maxxstick analog stick for movement on my keyboard, and it works fine for other games, but for No Man's Sky, it refuses to register my mouse as a control surface. The look controls are bound to RS, but because I'm only using the stick for movement, there is no RS.
