well anyway, i remade the evacuate button which was not that good anyway (aah me and design
here is mine with a corresponding ButtonImage and a specific sound (not tested though ) :
CommandButton Command_TransportEvacuateHobbit Command = EVACUATE TextLabel = CONTROLBAR:TransportExit ButtonImage = HSTheodenMountDismount ButtonBorderType = SYSTEM; Identifier for the User as to what kind of button this is DescriptLabel = CONTROLBAR:ToolTipTransportExit InPalantir = Yes UnitSpecificSound = TheodenVoiceDismountHobbit End
dont forget to replace it in commandset !
