Nowadays, a lot of cheap tools exist to get the job done. For instance, you can buy an older version of Poser for less than $100 on Amazon and sometimes less than $50, and of course, Poser isn't the only program out there. Anyhow, a big block to 3D animation is the time. Who has time to do it? As with any hobby, time must be set aside and it helps if it becomes a habit as people are creatures of habit.
