Gravity Select this check box to give a viewer some weight in walk mode. This option works in conjunction with Collision. Auto Crouch Select this check box to enable a viewer crouch under objects that are too low to pass under in walk mode. This option works in conjunction with Collision. Viewer Radius Specifies the radius of the collision volume. Height Specifies the height of the collision volume. Eye Offset Specifies the distance below the top of the collision volume, where the camera will focus upon if Auto Zoom check box is selected. Third Person Enable Select this check box to use third person view. In third person view, an avatar is shown in the Scene View to represent the viewer. Selecting this check box changes rendering prioritization so that objects around the avatar are displayed with much higher detail than normal. The size of the region of high detail is based on collision volume radius, speed of movement, and the distance of the camera behind the avatar. Auto Zoom Select this check box to automatically switch from third person view to first person view whenever the line of vision becomes obscured by an item. Avatar Specifies the avatar that is used in third person view. Angle Specifies the angle at which the camera looks at the avatar. For example, zero degrees positions the camera directly behind the avatar; 15 degrees makes the camera look down on the avatar at a 15 degree angle. Distance Specifies the distance between the camera and the avatar.
