3d models are structured in 2 file:
#.i3d that contains information about 3d models in xml language.
#.shape that contains 3d models structure
On dlc the .shape file are cripted, and giants editor crash when try to import a models with cript shape.
From my test i've discover thath:
Open i3d with normal shape file:
reading frist 4096 bytes,next 4096 bytes,next 4096.
finally it start reading shape from offeset 8192.
Open i3d with cripted shape file:
reading frist 4096 bytes,reading frist 4096 bytes,reading next 4096 bytes,
finally it start reading shape from offeset 4096.
This protected shape are parts of some DLC, and i've extracted dlc, fixed all encripted script then put into game like as normal mod. And it works until you try to buy element with shape cripted. this made game crashes.
I've figured this have different function for loading dlc and standar mod,then i've decripted base data from the game and i've find function thath load mod and dlc(it's lua script):
