modo has long been the application of choice for animation studios like Pixar Studios and Industrial Light and Magic. The latest update to modo improves upon an already amazingly powerful 3D animation tool.
One of the biggest complaints about the previous version, modo 501, was that character animation was noticeably absent. Luxology has addressed this complaint and have included character animations in modo 601. You can make static 3D models and flatten them for images or you can give life to your creations with the new character animation feature.
The features that made modo great are still here. The rendering engine is faster than ever, physics controls and fluid dynamics make your animations realistic, and the amazing Pixar subdivision surface modeling is still here, making your models much more efficient by reducing polygon count. If you are modeling people or animals, there is a new skin and hair shading and texture tool to make your characters photo-realistic.
modo also has a great community behind it that continue to develop kits for modo to expand its functionality and ease of use. Luxology also has a section on their site that allows uses to preview and purchase new kits.
Overall, its easy to see why modo 601 is the de facto 3D modeling application for professionals. Its ease of use and powerful feature set make it one of the best tools for artist and animators.
