Hi

I mainly do the precom= p in this project for easier organization of the project.
It is 5= small brochures each containing about 8 pages i have to flip through. Norm= ally when i do this i do it with all the pages in the main comp and link th= em to a null, but i just thought i would give this workflow a try this time= , and i just had a hope the expression 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!
