File Formats

oct

Tupperware container files for model metadata and textures. Use offsetting oct decode via the offsetting tool suite to convert them into JSON or YAML, and offsetting oct encode to rebuild them. Append -t to the end of the command to extract or embed textures. You take a deeper dive into the .oct format here.

mer

Meridian tree structures, stored as Tupperware. Use offsetting to decode them into standard JSON or YAML.

vbuf

Stands for Vertex Buffer. Used to store raw vertex data in a format convenient for the rendering engine. Metadata from an .oct file is required to properly parse these files.

ibuf

Stands for Index Buffer. Used to store raw index data in a format convenient for the rendering engine. Metadata from an .oct file is required to properly parse these files.

dct

Localization dictionaries. Use offsetting dct unpack to decode them into standard JSONs.

zip

ZIP Archives, with extra metadata embedded inside used by the engine's filesystem. Use the zip or zip-c2 tool included in offsetting to re-pack archives in a game-friendly format.

dds

Microsoft DirectDraw Surface textures. Can be viewed and edited with most image manipulation tools such as GIMP, Paint.NET, and Adobe Photoshop.

tfx

Groups of compiled HLSL (High-Level Shader Language) shaders, stored inside Tupperware files. Use offsetting oct decode to decode them into standard JSON or YAML.

swf

Standard Shockwave Flash files. Used by the game's Autodesk Scaleform-backed UI system.

anno

Modified version of an Annosoft Lipsync Tool output file. Contains phonemes alongside timestamps that the game uses to lipsync characters mouths to audio.
