Only if you're working for yourself or a small studio.
You don't HAVE to be creative and expecting / wanting creative input may even be discouraged. A dude from Pixar talking at an Autodesk thing said the single best thing you can do to get a job is to take someone else's concept art and make a character from that.
He talked about how in these large studios your technical skill and experience is what matters much more than your artistic skill; a team of creative people are going to iterate over a design repeatedly, and in the case of the Pixar guy you're going to have the Creative Director or whoever standing over your shoulder saying "Change this, change that, make this bigger, make that smaller, rounder, longer, etc" as they iterative over the initial character designs.
TL;DR if you're not creative, find someone else's creative concept art and turn it into 3D
