This tool allows you to extract (most) data from CGFX files. Everything that is extract is placed in a folder named after the original file (without the extension).

This tool wouldn't be possible without the work of many people who have stumbled into this mess before me. In no way would I have been able to make this tool without the information they provided via Wikis or source code. I am in no way trying to take credit for their hard labour, I merely want to make a tool that can be easily used in scripts. A full list of acknowledgments / credits is available below.

• ⭕ General Metadata
• 🚧 Vertex Data
• 🕓 Material Params
• ⭕ Textures
• 🕓 Camera Infos
• ❌ Look-up Tables
• ❌ Shaders
• 🕓 Lights
• ❌ Fogs
• 🕓 Scenes
• 🕓 Skeletal Animations
• ❌ Texture Animations
• ❌ Visibility Animations
• 🕓 Camera Animations
• ❌ Light Animations
• ❌ Emitter Data

⭕ implemented , 🚧 work in progress , 🕓 on the todo list , ❌ maybe in the future

All you need to do to build the tool is run cmake and then make. Personally, I recommend doing this is in a build directory to keep things organised, but that is optional.

$ mkdir build && cd build
$ cmake .. -DCMAKE_BUILD_TYPE=Release
$ make

So, for example, the file some_model.bin could be extracted like this:

$ ./cgfx2gltf -v some_model.bin
