You know the one, it's looks like a big wheel with a portcullis in it. Anyway, I'm trying to set one in my dungeon and believed that this door would act like any other activator door and just need a linked parent switch to open it. It seem that's not the case however, so what's the trick to getting these doors to work.?

I think they work off animations, so you may need to state an anim start for the door, I suggest taking a look at one of the vanilla ones, if you can't remember where those doors are used check Halldir tomb.

Thank you. They need a script adding to the switch that can be found in the list of pre-existing scripts.
