Does not generate the textures automatically when the scene is loaded as it is set to "DoNothing". RebuildTextures() or RebuildTexturesImmediately() must be called to generate the textures. After the textures have been generrated for the first time, they are cached to disk/flash to speed up subsequent game/application startups. This setting will not load the cached textures automatically when the scene is loaded as it is still set to "DoNothing". RebuildTextures() or RebuildTexturesImmediately() must be called again to load the previously cached textures.
