I am trying to have a custom upgrade for the Terran command center where by it upgrades to a biodome command center. Currently I can get the upgrade to work, but the model for the command center does not change after upgrading(It would be similar to upgrading a command center to an orbital command), I have searched through the previous posts and can't figure out how to go about editing the actors(if that is what needs to be done?)Any input on this problem would be greatly appreciated!
