1. Decrypt BigFile_PS3.sdat (use google)

2. Use b2s_big_models.exe on the decrypted file to unpack the segments with model data (characters, maps, objects, weapons, machines, etc.) You can do the same with other BIG files, such as GAME_PATCH and SetupBigFile_PS3.

(If you can not decrypt BigFile_PS3.sdat - use beyond_segs_2d2d2d2d.bms, which will unpack ALL segments, not just the models, however, they can also be converted in the same way)

3. Use b2s_DC.exe on the received .segm files. It will extract models and textures. char_char.txt and char_segm.txt files are approximate (possibly incomplete) lists of characters and their clothes, sorted by name and by segment code. Some big files (usually maps) will give out errors. Nevertheless, the most of it can be exported even in this case.

Static models will be in the format .ASCII, skeletal models - in the .SMD format, the skeleton itself in a separate file. If there is a bonenames.txt file with bone list, these bones will have the correct names. You can add your names to this file.

4. Some textures will be in the .DDS format, the rest (without extensions) must be converted using b2s_imgdc.exe for example using .bat file

A small part of the textures can be in 4-byte RGBA, 1-byte formats, texture packs .rawpackage or .package - they are not yet supported.

========================================================================================
Update: 
- added weights to cloth meshes 
- helper bones reparented
- Heavy Rain tool for .segm files

Heavy Rain tool (hr_DC.exe) is used in the same way, except that you do not need to convert textures with b2s_imgdc
