I tried to edit an existing in-game activator (animated) object with Blender (
KvatchCastlePortcullis02.nif) in order to cut its height and make it more suitable for the shorter castle gate, however I couldn't figure out how to export it properly from Blender into a correct and functional animated object. It seems I could only apply one animation (forward or open) instead of the two animations like its original object. Since it couldn't be done with Nifskope, I am stuck at the moment.
Thanks!
