Adding Sprites, Models, and Sounds

[Jerezereh]

I need to add custom sprites, models, and sounds for my mod. I tried modifying the GUI/GauntletUI/spriteData.xml to add custom sprites (the default one, I also need to find a way to override it with my own mod file), but even with all the files in place I have only been able to get as far as a null Texture object which displays a bright pink box instead of nothing. I've been trying to find where Texture objects are initialized, but so far have been unsuccessful.

I have not looked far into adding 3D models or sound files. I noticed the native files are compressed into tpac and bank files, does anyone know how to view or edit these? Or is there another way I can load custom resources?

Thanks
