My mod has some working curtains. There's 2 objects, both of which are activators: the closed curtain and the open curtain. Activating whichever one is enabled runs a simple script which toggles an XMarker which is the Enable parent for both curtains. Both of them are set to "pop-in" under the Enable Parent tab. But they only ever do fade in/out. It seems that activators do not pop-in no matter what I do. I did a little test, and static objects will pop-in if set to do so.

Is there any way around this or am I going to have to replace my activators with statics and go about this another way?

Okay. I tried my own suggestion of using the static curtains that are already in the game (NVTOPSCurtain03 and NVTOPSCurtain04 respectively) and just sticking a plain old ElectricalSwitch behind the wall, but the same thing happens! The curtains refuse to pop-in!

I tried other static objects and they seem to work fine. Is it possible that this is something to do with the curtain model that prevents it from popping in?

I made a simple esp to demonstrate the problem: https://www.dropbox.com/s/al8pwibx8ow3qsv/CurtainPopInTest.esp?dl=0

Load it into your game and type "coc CurtainTest" in the console. You'll also need to use "TCL" to fly into the room. After which, the switch will enable/disable the curtains.
