If you are at a stage where you are considering if animation is the right career for you then you are at a very crucial stage. Decisions you have to make at this point must be adequately informed. Many people have gotten themselves into these lucrative and expensive 3D animation courses only find out afterwards that all there is not what they wanted to do.
What you need to do pn the onset is research and establish what you really want to focus on as you are settling in 3d animation. It is great for you if indeed 3D animation is your passion. The success prospects in something that you have a passion for are high as you will always perform at your best in investing your energies and passion. IT will be wise to get to an understanding of what a particular course in animation will lead you to ultimately in the career line.

This may extend to rendering rather than developing characters. In the lighting department the job involves setting up lighting for particular scenes and in this job line you will be responsible for ensuring that the 3D piece looks the way it is supposed to look and get the right feel that it should get. In this case you will be functioning as a lighting artist.

If this is what your jobs revolves around then you are a 3D modeler. If you have invested more into painting tasks as well as creating textures that are going to function as encasement for characters then you are a texturing artist. It is important to get good basic knowledge about these design animation tasks and responsibilities. This will help you to know what exactly you want to do and what course you then need to pursue.
