Freelance 3D artists create small-scale 3D models and environments for architecture, design, or event planning firms, or they may work for graphic design, animation, or video game firms to develop images and animation for programs. They use specialized software, such as Vray, 3DS Max, After Effects, Photoshop, Unity engine, or Cinema 4D, to produce three-dimensional backgrounds or digital content for software or websites. Companies hire freelance 3D artists on a short- or long-term contract basis; many independent contractors work from home, while others may travel to the office or a dedicated company studio that has the equipment, tools, and software needed for the job.
