Replace textures in real time in asset editor.

TextureReplacer_AssetEditor.cs

// Texture Replacer script by Ronyx69
// ASSET EDITOR, not ingame

// Replaces textures in asset editor in real time!
// Much thanks to SamsamTS for explaining Actions to me and being helpful.

// D, ACI, XYS textures for buildings, props, vehicles and D, XYCA for trees.

// Unfortunately CANNOT replace LOD textures.
// Technically I know how to replace LOD textures, 
// but ingame they are combined into one big texture atlas on level load.
// I would like to know how to rebuild this atlas ingame, 
// but I don't know how. Do you know?

// Tree LODs work since that's different. 
// Camera needs to be moved for tree LOD to update.

// SCROLL TO BOTTOM, IGNORE THIS (under the hood stuff)
