The ScriptFile is a special type of text file used to declare several information, you can think of this format as the JSON of Metin2.
The format is a simple Dictionary with the ability to contain Group and Lists.
Each key and value is divided by a TAB (/t), do note that the "4 spaces" does not work in replacement of a tab.
Comments are done with either * or //
Example:
ScriptType Test Usage:
Key(TAB)Value1(TAB or SPACE)Value2(TAB or SPACE)  
Commas
commas are used to let the client parse multiple values into one.
Example:
TestKey(TAB)TestNode TestNode2 In this case TestNode and TestNode2 would be readed as two different values.
TestKey(TAB)"TestNode TestNode2" In this case TestNode and TestNode2 would be part of the same value.
 
Groups
Usage:
Group (name) {} The groups are containers of keyvalue and are divided by the {} the key group MUST EXIST or the group is not considered valid
Example:
Group Foo { Test "1" Group2 33 }  
List
Usage:
List (name) {} Example:
List Foo { 32, 55, 49, "bar" }

The Property files are a special type of Script file that defines informations about the objects that are contained inside a Map.
A property file MUST start with YPRT (and next line), this is the magic check that a property file does.
The next line of the property MUST BE the CRC32 of the object file name (which will be used to build a CRC32 map that will get loaded by AreaData files.
The remaining lines are parsed as a Script file, there are different lines.
Between all the Property files that metin2 can load, there are two options (apart from the magic and the crc32) that are always present in any property file.
Common options Name Description Possible values PropertyName Defines the name of this property A string PropertyType Defines the type of this property A string that must contain a valid property type The property type also affects the extension that the file MUST have, each property supports extra options (except for None property).
Here is a list of all supported properties:
Supported properties Name Extension Description None .pr This seems to be an empty property without anything extra. Tree .ptr A tree object that will be rendered with SpeedTree. Building .prb An object found in maps. Effect .pte ? Ambience .pra ? DungeonBlock .prd Blocks used to rapresent the area of a dungeon.  
Building
building options Name Description Possible values buildingfile Defines the GR2 of the model that will be loaded for the building. A string shadowflag We suppose that this flag was intended to be used for disabling shadows in objects, and despite the game contains reference of it, it doesn't seem to affect the building in any way. A boolean (1 = true, 0 or undefined = false)  
Dungeon block
dungeon block options Name Description Possible values dungenblockfile Defines the GR2 of the model that will be loaded as a block. A string
