I mainly do the precomp in this project for easier or= ganization of the project.
It is 5 small brochures each containin= g about 8 pages i have to flip through. Normally when i do this i do it wit= h all the pages in the main comp and link them to a null, but i just though= t i would give this workflow a try this time, and i just had a hope the exp= ression would work through the precomp if it was set to continous rasterize= . But, it didn't. not unmodified that is.
I will probably end up copy/paste the animation of the precomps to a n= ull, and set up all the page layers in the main comp as i normally do :-)

Maybe it is time to do a small feature request for = a checkbox on "flat" 3d layers to only render the front side, the= n you didn't have to use the expressin and it would work with the cont.= rasterized 3d precomp too.

It might help if you posted a pic of what you're doing. If you're u= sing continuosly rasterize, it doesn't really matter what the size of y= our precomps are, does it? Are you nesting your precomps for compositing, o= r for grouping/parenting/organizational purposes?

So i think an updated expression is the only way to go, or doing it ma= nually with keyframes.... my last resort :-)

perhaps linking precomp camera's attributes to the main comp's one.=

tell me if it works!
