Just looking at how this modifier can be used to showcase 3 different levels of subdivide, made me think about the graphics settings in video games on PC, and how they have various levels of graphical quality for a variety of PC specs, low to high....
...anyway, it got me thinking, could the Multiresolution Modifier be used, or is it used, to make copies of the meshes we create for the purpose i outlined above?
Technically yes you could produce LOD objects, but I feel like they still would need some geometry optimization. So maybe for creating the base LODs.
For those who don't know, LOD is level of detail which is an index number used in game engines to choose/switch which texture and/or mesh to use based on a parameter such as graphic detail setting or distance from camera.
