Ubisoft LyN Engine: Binarized Parameter Files

[LolHacksRule]

I'm currently datamining data in Rabbids Land, a game using the LyN Engine from Ubisoft, I wanted to see the values for the parameters after extraction, but unfortunately the majority of parameters read by the game are in some binary format, which makes it tough to diff them their true values from the day 1 patch. I attempted to document a portion of the format, I may be wrong on some information but I tried my best. If anyone else wants to contribute feel free to.

Code: Select all

UbiLyN Params:

In INS:
   16bytes: DEC0DEC003000100050000000000000000000000 (Sounds like a message to modders or game engine)
   4bytes: ?
   4bytes: Float of some sort
   
In MDL:
   4bytes: Float of some sort
   8bytes: DFC0DEC00000000
   1byte: Total param count (Int)
   7bytes: 00000002000000
   1byte: ?
   
   offset 40 is always the first param name (after ignoring beginning float bytes) and appears to go up by 40
   EOF: somewhere before 4D6F64656C466163746F7279 (ModelFactory) to a bunch of 00s
