The FXtree is huge. annoyingly, i never intended it to be complicated. You initially just have a diffuse, bgd,shadow and occlusion pass to comp, but then theres masking issues, transparency issues, reflective issues and it just grows into a monster that only the user understands... id rather not post it. The only thing i can say is that the more elements you have broken up - diffuse separate to reflection, interior separate to exterior - the easier it is to control it in post, this saves on re-rendering whole sections so instead you're just re-rendering an annoying little geometry crash in the windscreen and not the whole car...As far as the noise goes, it was a personal choice to put it there, it looks worse on the lower quality jpeg on this site than it does on the outsourced uncompressed jpeg links.
If you look at transformers2, each shot had roughly anything from 50-90 passes, it's so intense for the compositors but, that's because each frame took like 70 hours to render, so render tests and re -renders are out the window(i'm supposing?) breaking it up gives more control to fix issues...
Nothing's too difficult to achieve, it just takes longer...
