Question: 3D files??

[GuillermoZS]

Hi, I want to start modding some 3D objects in the game (ships, subs, interiors,...) I have experience with maya and 3ds, so that´s not the problem. I have some questions related to the game structure:

1. Where are the 3D object files? Are them compressed in the .dat/.dsd/.sim files I´ve found in the directories? If so what apps do I need to decompress/recompress them?

2. What are the .dat/.dsd/.sim files for (I know .dds are textures but .dsd?)

3. Is there any plug-in needed to import/export the 3D files for the game?

Any info is much appreciated :D

Thanks a million!

Ok, now I know 3D models are in the .dat files and I´ve found pack3d tool to extract this files but I´m using Vista64 and this app doesn´t want to work properly in this os... It doesnt open the dat files: when I try to open one it just hangs....

Do you know any other app for extracting/recompresing .dat files?

Thanks!
