Bake MultiPass materials during export

[ShreeRam.Nair]

It would be great to have the ability to bake materials for export to other DCC's. Especially multipass materials, for example:

In this case this is a MultiPass material containing two separate materials, after baking, the red "decal material" and green "base material" will be flattened into a single output for each channel respectively (Diffuse/Roughness/Normal etc). The baking process should also generate textures based on the current UV maps or have the option to automatically do a quick unwrap for the objects.
