Description

Returns the name of the AssetBundle Variant that a given asset belongs to.

If the asset has been explicitly assigned to an AssetBundle Variant, then that value is returned. If the asset doesn't belong to an AssetBundle Variant, its parent folders are traversed until one that belongs to an AssetBundle Variant is found. If a folder that matches this condition is found, its AssetBundle Variant name is returned. If none is found, an empty string is returned.
