>>500314>im currently in university and i'm wondering if i can freelance on the side some game assets for various companies, like a contract thing.
Sorry but no. You're not going to earn a contract like that without already having years of experience and great art skills. At best, you'll be able to learn enough 3D on the side to get some shitty jobs on Freelancer.com
where you have to compete with third-world people who can afford to accept $4 an hour pay. All while Freelancer takes a %10 cut.
Learning to do Archviz would be a much more realistic proposition. You can pirate model packs with thousands of objects to use and start taking jobs on freelancer for some side dosh, maybe earn an employer to work with off-site. But again, you still need to be very good, so it will come down to your natural talent for learning this kind of stuff quickly and having a good eye for design.
