DEFINITIONS
###################################################
Terms Used through out this Readme you should know:

PS2.0 or PS1.0:
PS stands for Pixel Shaders. Most modern video cards support at least
2.0. Some cards may only support PS 1.x. If your video cards does not
support pixel shaders 2.x then some of the features of this mod will
have to use the default Maxis items (Like Pool Water etc)

Diffusive Lighting:
In the game diffusive lighting is light that affects walls and floors Only.

Practical Lighting:
In the game practical lighting is light that affects Sims and Objects Only.

All lights SHOULD have both diffusive and practical lighting. A lot of Maxis lights did not.
Most do now (See Bugs Below)

Portals:

Portals are basically little boxes. A room with no doors or windows is a portal.
A joining room with a door is another portal.
A Window is a portal.
A archway is a portal.
An opening in a wall is not a portal.
Light can ONLY travel through 1 portal length.
If you have 3 rooms in a row with archways, the light from room 1 will only travel to room 2
and not into room 3 UNLESS Room 3 is connected directly to room 1.
Light from Room 2 would travel to both Rooms 1 and 3 because both rooms are directly
connected to Room 2,

BUGS:
#######################################################################################

These are bugs not caused by the mod but rather are limitations either in hard code (game exe)
or limitations of the 3D engine itself. If a bug is listed here it means that this item could
not be fixed or worked around. Just because you did not notice a bug before doesn't mean it wasn't there.
The default maxis lighting was very bright so a lot of these problems were not as noticable.


FIRE EFFECTS -
#############################################################################
Fire effects are hard coded to a degree.
While I can change the color of the light thrown by fire I can not force diffusive light
on floors or walls. So only Objects and Sims will get lit by fireplaces, not walls and floors.
The bonfire object is supposed to be a 2 stage object. Unlit it doesn;t emit light,
when lit it does. However, the problem is the second stage never turns the diffuse lighting
on, only the practical lighting.
So to some it up, Fireplaces, the Bon Fire and the Firejet do not emit diffusive light, only practical light.

FOUNDATIONS/DECKS -
###################################################################################
In the game light must follow the portal rule (see Definitions about Portals Above)
Unfortunatly a Foundation is considered a portal.
This means that light affecting the foundation will not affect on the wall above it.
This also means light affect the walls will not affect the foundation below it.
The only way to force this is to make a very powerful light that seeps into the
other portal but this is undesirable.


BROKEN LIGHTS:
#####################################################################################
Computers and Aquariums - The light for the computers/aquariums leaks through walls.
I have disabled lighting on the computers/aquariums. 
The only way to fix this would be to make new computers/aquariums which
reference lighting that does not "leak"
Lunatech "Lighten Up" Lighting Fixture- (Second from the Left Top Row of Overhead Lights for $75)
Ok, this light is broke. For some reason when Maxis coded this light they made it a spotlight
rather than a pointlight. Even making a new package file with the light as a pointlight
will not fix this light because it's name has Spotlight in it which overrides the "pointlight" features.
As a result I have made this light work like a recessed light embedded in the ceiling would work.
(Imagine lights you see in a hotel lobby that are upside the ceiling)
Light will shine directly down and illuminate things below it but it will not "light up" a room
unless the room is very small. Also note that objects high up on the walls will not be lit at all
with this light (Like smoke detectors, etc)
This means you will WANT to go into any lot/neighborhood/downtown and either
replace this light with another, or readjust the lighting for these lots.
Sugar Bowling Alley in NL Downtown is a perfect example.

CORRUPT LOOKING GRAPHICS IN NEIGHBORHOOD VIEW (Not the Red Flashing):
######################################################################################
This is not a result of the mod. I found that under the following tests I could reproduce the problem.
If you own an NVIDIA grahpics card the bug will manifest itself under the following conditions:
1) Anti-Aliasing in NVIDIA control panels is forcing AA.
2) You have an SLI Rig (2 graphics cards running as one) and have SLI enabled for the game.
Fixes:
1) Turning of Smoothing in the game AND disabling AA through NVIDIA controls for the game
2) If you have SLI, disable SLI for The Sims 2 Profiles.

OUTDOOR LIGHTS ON A POLE
#########################################################################################
Due to the new way lighting works, for an outdoor light on a pole, example, a streetlight,
they MUST be placed at least 2 tiles (in build mode) away from a building WITH A FOUNDATION or they will not light properly.
You CAN place say a streetlight next to the wall of house, but it must be rotated to face away from the structure.
