Illustrator Vectorfiles in AE 3D Space - Blurry??

Hello,

I always run into this problem and up to now slitherer around it with cheating but that can't be it... I hope!

I got a multilayer Illustrator File to animate... lets say a compass. I place my layers in one composition, animate them and throw it in a new PAL composition for 3D Animation and rendering it. Now when I turn the composition into 3D and want to animate a camera move on it to turn up real close the composition gets blurry. The usual hint is turning "continuously rasterize" on, but I did this. I did it in my source layers in the basic animation comp and I do it on my layer in the final 3D composition. But if I turn on "continously rasterize" I can't use the layer in 3D space.

Please someone tell me you don't have to prepare a 5000by5000 Pixel composition to animate the basics and then throw this in an new comp for 3D Animation like a large photoshop file. Thats the way I always cheated but its damn slow and pretty ridiculous when working with vector images. Someone please lead me to the magic button I never found! :)

Thanks in advance,

Karim
