Render multiple versions of one comp with Different settings?

[CK Dexterhaven] “Yes you can (and presently, must) create separate comps to do this but if you have 10 different comps with shared backgrounds or elements, then the client changes the background, you have to edit 10 different comps instead of one. ”

Or set the shared background up as a pre-comp and change it once (;

You’re right Darby, pre-comp is the way to go with a shared background. Bad example there…

As was mentioned earlier though, being able to set in/out points, turn layers/effects etc. on/off and create renderable layer comps a la Photoshop from one comp would be very productive and helpful.

This may seem like a really tedious idea to some, but couldn’t you create a new project for each version, and start at the project level, so anything parented to anything else, or backgrounds etc. would all remain?

I know this an 8 year old thread, too, so maybe there is some explanation for this now.
The render queue shouldn’t need the project to be open to run the render, right? Maybe this is the same as precomping and making separate comps, but I find a project file for each revision to be of good habit anyways, so you can always go back to where you were, or if you have multiples to edit, like lower thirds.

I am ending up renaming 15 or so project files, each with a different name and title. But I do wish there was an easier way. if I duplicate the comp, everything in that comp is linked to it, so when I change it, it changes every other one. So I end up using projects as comps…This seems silly to me. Am I just doing it all wrong?

Thanks
