Detailed Description

Level of detail strategy based on distance from camera to an object's bounding sphere.

The purpose of the reference view is to ensure a consistent experience for all users. Monitors of different resolutions and aspect ratios will each have different results for the distance queries.

: It depends on gameplay testing. If all testers had 16:9 monitors and 110° FOV, then that's the value you should enter (to ensure as much as possible the experience stays consistent for all other users who don't have a 16:9 monitor and/or use a different FOV).

: If all your testers had 4:3 monitors, then enter a 4:3 resolution.

: If all your testers had varying resolutions or you just didn't care, then this feature is useless for you and should be disabled (default: disabled).
