Through the years, software gets developed and enhanced along with their newer release. Some give changes in both features and price, some others are free. However, the free ones is no longer considered as tools to have fun. Blender for example. It is now considered one of the most powerful 3d modeling, animation, rendering and visual effects software on earth. It has evolved into something that can directly compete with other commercial software, offering many features, giving the answers and solution to many animators and graphics artists.
