sorry brian, i know this is ur thread, but i have a question for all u car modeling experts... does it matter if the model stay seperate? or i have to connect them back into one piece after all the modeling is done? like...the wheels and some headlights, spoiler, exhuasts...etc, or is it ok to just let it be alone? or is it even ok to have it cross each other when they're not combine as one object?
