Vsion
Basics
[edit]In classic EverQuest characters had three levels of vision: normal, Infravision, and Ultravision. Some races started with superior vision, and this was considered a meaningful racial feature by the games developers. There were numerous spells and items which granted characters of other races improved vision.
In addition, classic EverQuest also includes a large number of light source items. These items had 15 different degrees of illumination, which radiated from the character wearing /wielding them.
Project 1999 and the Titanium Client
[edit]The way lighting worked in EverQuest changed over time, and by the time the Titanium client came out the game was ... well a different game. The developers wanted everyone to be able to see well, and so vision levels/lighting had a much more muted impact in the Titanium Client.
Because of this, and because Project 1999 used the Titanium client, for a long time vision/lighting didn't matter much on Project 1999. However, in anticipation of Green, the hard-working P99 volunteers have started finding ways to work around the Titanium Client limitations, to make lighting matter in a more classic way.
As a result, Project 1999 players should expect ... as with many things ... a "close to, but not perfectly accurate" lighting/vision mechanics on both Blue and Green.
