Im trying to increase my comp size without effecting my duik rigged puppet and animation but it keeps breaking my rig? Is there away to only effect the size of the comp and not the stuff in it?

None of the previous suggestions were working for me,tranformation/continually rasterize was messing up the 3D workspace, so here was my fix if anyone wants it:

1) Make sure tranformation/continually rasterize is turned off on the layer your puppet is on and pre-comp it.

2) Collapse tranformation/continually rasterize the puppet layer inside the pre-comp.

3) Resize the pre-comp and adjust accordingly in your main comp.

Hope that helps someone!

I found  a really easy fix for this problem.

step 1: open composition settings (ctrl+k), select the top left corner as anchor in the advanced tab and resize the comp to your needs

step 2: create a new adjustment layer and place on top of everything

step 3: add the "transform" effect to the adjustment layer. There you can change position, scale, etc and your rig stays intact.

Hope this helps someone. Cheers!!

you'll need to go to the Advanced tab in the comp settings

And check the upper left corner as the pivot for resizing

same problem. I use "file/ scripts/ scale composition.jsx". my comp size increase, but my rigged puppet remain at the corner, not middle...

Try simply collapsing transformations in your nested comp. Changing the comp size is going to foul up a bunch of stuff unless you use a script. Collapsing transformations is the right way to solve your problem.
