When I say "for a few frames" I really mean for a few frames, not the entire shot.

I was going to suggest embedding the action and deleting that tower out....then put it into the chor separately but there may be changes made to the action before the movie's done.
I'm thinking I may have to make a copy of the action, delete the one tower action object and then switch between the original action and the altered copy during the shot and hope that no one changes the original action later without me noticing it.

Sooo....what about putting a transparency pose on that tower?
AFAIK It's not possible to apply a pose to one of several instances of an action object in an action. I haven't succeeded in getting a pose to affect an action object.

Or just copy and sub the model. Copy the model file to <model file name>-special-001.mdl then delete whatever towers you want. Then, in a copy of the project file, sub in this modified model
Copying and altering the set model won't work because the towers are not in the model available for altering, as noted above. Altering the tower model would change all of its instances not just one

You can access the action objects, in the bones folder of the model the assembly action is applied to, in the chor (show more than drivers). There you can set the object inactive.
That sounds like it ought to work, but can you show an example of actually animating the "Active" of an action object on and off in one shot? I haven't succeeded in getting that to stick.
