Hasta La Motion!

I’ve recently been in a situation were several artist are working on the same shot. One person on keying, one on roto, one on comp and so on.

I would like the person that comps the elements together to start working with temp keys, and temp rotos, and then be able to switch them out as the project goes along. I don’t want to render out the elements, I want the compositor to import the key comp so he can have some flexibility if he needs it.

Is there a way to “replace comp”, almost like the replace footage button, without having to import the project again and manually switch out the comp and delete the old stuff and so.

Dynamic link between AE and AE?
