Is it possible to make a prop_dynamics animation start at a specific frame, or freeze at a specific frame ingame?

I think it's possible, though not easily. I'm not quite sure how, though. Maybe playback rates?
(I'm sure someone will jump in and give a way).

yep srs is right; if you time it properly you should be able to set the playbackrate of a model to 0 making it play only half the animatino.

well, i dont know if you can make it start at a specific frame, but if the model isn't visible from where the player is spawning you could make it play the animation with a logic_auto and set the playbackrate to 0 at the right moment to make it freeze there.
then when you want it to continue animating, set the playbackrate to 1 again.

what if i want it to start in the middle? that's not possible is it?

just make it play the animation while the player is in the elevator, then stop it halfway through. Then set the playback rate to 1 once you want it to play.

Oh i get it now. that's actually perfect. i can use two models where one is disabled and then i swap them out when needed .

thanks
