Basically the only difference between the cmx names and the bmp
names is the lack of skin color information in the cmx file since it can be
shared among all three skin tones.
There has always been a skin record for assigning Normal,
Formal, and Swimsuits.
In Hot Date this record was moved and the ability to assign
skins by body name was disabled for most items.
Starting with Hot Date Formal hands also no longer work by
assigning them in the skin records. (In fact I have not found a way to make them
work since the game now just ignores the changes)
HD - Names are standard names for Hot Date skins. Users of
SimEnhancer will need to use Hot Date names for Formals and Swimsuits if they do
not have Hot Date or Vacation Expansions if they are changing skins.
VI - Names are standard names for Vacation skins. Users of
SimEnhancer will need to use Hot Date names for Formals and Swimsuits if they do
not have Hot Date or Vacation Expansions to use it for changing skins.
Lingerie was not added as part of the character skin data
until Hot Date. To change the Pajamas you will need to assign names that match
the body to work if you do not have Hot Date or Vacation.
Winter was added in Vacation and is not available on any other
version.
Hands and Nude Skins use a slightly different naming
convention than the normal one above.
