The mipmap level to load.
Normally, the mipmap streaming system will select which mipmap to load based on the position of all cameras. Setting this field forces a specific mipmap to be loaded and overrides the mipmap streaming system. The mipmap level can still be modified by budgeting memory. The streamingMipmapsPriority property can be used to increase the chance of a particular texture mipmap level being selected by the mipmap streaming system.
