Texture Override

Untested.

SDTextureOverride.json

This JSON is used for mapping HD textures to the SD (original) textures.
It consists out of an "Mappings" array which holds entries with the source texture path and the destination texture path.

Texture modifiers

When an texture gets used it can have different modifiers.
When adding modifiers to an texture path string the '?' symbol is used.
To give the modifier a value the '=' symbol is used following the value.
When adding multiple modifiers each modifier is seperated by the '&' symbol.

Example: gacrmegg_1.png?usage=0&alphamode=0

Name	Values	Description
usage	0	Unknown (Shader sampler selection?)
alphamode	0 - 2	Texture alpha mode?
font	0 - 6	Used for loading fonts (fontdef)
image	0 - 6	Used for loading fonts (fontdef)

Headerless Textures

Some textures with the PNG extension are headerless DDS files. Why they did that is a mystery.
