GTA III - San Andreas

Format

ID, ModelName, TextureName, ObjectCount, DrawDist, [DrawDist2, ...], Flags

Identifier	Description
ID	unique object ID (integer)
ModelName	name of the .dff model file, without extension (string)
TextureName	name of the .txd texture dictionary, without extension (string)
ObjectCount	amount of sub objects, e.g. damaged parts, usually 1 (integer) - optional for SA, default 1
DrawDist	draw distance in units, one for each sub object (float)
Flags	object flags, defining special behavior, default 0 (integer)

Object Flags

Object Flags in SA are text formatted UInt32-Values (Like nearly all other Flags). To understand them better you have to calculate them to binary numbers. Then You will get the Bitsets of the Flags. 1 means Enabled, 0 disabled.

List of all known flags for San Andreas:

* If there's no Interior the Texture behind the object changes to black (=> IPL | Interior-value)
** Objects needs to be activated using Object.dat
(?) Not 100 % known
... All Flags in a special interval are unknown

To connect different flags you have to add the bit which belongs to the flag. Its the same as adding one value to another..

01 + 10 = 11
1  +  2 = 3

GTA IV

ModelName, TextureName, DrawDistance, Flag1, Flag2, (Bounds min)X,Y,Z, (Bounds max)X,Y,Z, (Bounds Sphere)X, Y, Z, Radius, WDD

Note that GTA IV does not use any unique object ID numbers
