Freelance rendering jobs involve creating 3D images of buildings, products, and other items using a computer program. As a freelancer, you work on an independent contract basis with different clients. Your duties vary depending on the applications that you use and the industry in which you work. You can design products for manufacturing, fashion, or merchandising with software like Maya, Keyshot, or Rhino. If your responsibilities focus on creating renderings for an architecture client, you may use 3D computer-aided design programs or building information modeling (BIM) software, such as Revit. Revit includes construction information as well as visual elements.
