Six is right. Everything that is linked to the animation dummy will not tilefade. You can check in-game if something is linked to the animation node by typing ##DebugMode=1 and ##renderaabb 1 in the
'chat window' (whatever that thingy is called
'>). This will render the walkmeshes instead of the models, but everything linked to the animation dummy will still be rendered.
You can reparent those nodes to the aurorabase with a texteditor, but you got to make sure that you also change the parent of those in all the animation information if there are animations for that tile.
