Unity Game Optimization - Third Edition

Avoiding camera physics collisions

In VR and AR, the user can move the camera through objects, which can break their immersion. Although it may be tempting to add physics colliders to such surfaces to prevent the camera from moving through them, this will cause disorientation in VR since the camera will not move in unison with the user's movements. This could also break the positional-tracking calibration of an AR app. A better approach is to either allow the user to see into objects or to maintain a safe buffer zone between the camera and such surfaces. If we don't allow the player to teleport too close to them in the first place, then there's no risk of sticking their head through walls.

This will save on performance because of a reduced ...
