Basically if you were to create a building, you could drop a DMM helper onto the object with a lattice of where the floors would be, then when that building is damaged DMM would generate the floors and walls inside, instead of having to model floors and walls creating assets that may or may not be used. The floors and walls would have texture references from the model or the material library. The user would be able to set floor height and wall distances or room sizes. It would save alot of time for the modelers, especially for an in-game asset.
