I've read through the best practices guide, but I don't recall seeing anything regarding handling when someone looks TOO closely at something. This seems like it'll be an even bigger issue with positional tracking.
The only things I've thought of are:
-Allow the head to enter the object, so the player can see inside stuff. Seems like it would break immersion pretty bad.
-Stop the camera from moving too far. This seems like it would work better, but breaks the rule of "head movement always matches camera movement"
-Fade/cut vision to black so nothing can be seen til the player's head leaves the object. This seems like the best answer, but not particularly easy to implement (at least for a newbie like me)
What have you done to handle this problem?
(FYI I don't have a rift. Trying to develop without til CV1, so I don't have experience with demos to see how they've handled this)
