Take it from someone who absolutely can't draw....it's not necessary..but it sure wouldn't have bothered me to have been able to draw when we were storyboarding in school (and it would have been nice to have DRAWN a better character that I wanted to use for my demo reel)...lol...but no one I've talked to has not been good at 3d animation because they couldn't draw....you just need to have a passion for 3d animation...good luck
