A virtual world controller receives an identifier of a detected interaction by a user within another world, separate from a particular virtual world environment accessible by the user, from a device that detects and reports user interactions within the other world. The virtual world controller identifies at least one particular trigger tag name assigned to the identifier of the detected interaction from among a plurality of separate detectable user interactions in a trigger tag database. The virtual world controller identifies at least one particular asset class from among a plurality of asset classes specified with the particular trigger tag name within a particular trigger asset coupling from among at least one trigger asset coupling in a trigger asset coupling database. The virtual world controller accesses at least one particular asset assigned to the at least one particular asset class in an asset class database. The virtual world controller renders the at least one particular asset within the particular virtual world environment in a virtual location within the particular virtual world triggered by the particular trigger asset coupling.
