teacher probably doesn’t know.
anyway…you can sculpt fur…just like anything else. But you need to remember, it’s a material that you’re sculpting on (stone, clay, etc). You don’t get small tiny strands of hair in a sculpture because the material isn’t strong enough to support tiny strands…the way hair actually is.
So then you have to ask yourself…do you want each strand to actually be there, or do you want to sculpt each strand. Each have their own benefits. Sculpting in fur/hair takes a lot of time and energy and will render very fast. While using a fur shader inside of a render engine will give you each strand, the ability to control it dynamically (if you need) as well as animate it…add physical forces to it…gravity, wind, etc. But fur takes a long time to render as you’ll be telling the render engine to give you hundreds of thousands of strands of hair.
Both are viable options and the decision is up to you…or your client (if that was the case). Weigh the pros and the cons and decide from there.
Just a tip…hair sucks…but you need to learn it at sometime…now seems as good as any to me…but then again…hair sucks in a render engine as well…and you’ll need to learn that at some point as well.
