AutoDesk MotionBuilder: Using the Real-Time 3D Engine
For those of you who are not familiar, AutoDesk MotionBuilder is a very popular software program that is used for creating animated effects. It has a user friendly interface, making it is easy to use. When deciding to use the AutoDesk MotionBuilder software, you need to know a few things about the Real-Time 3D Engine.
AutoDesk MotionBuilder: Using Windows
The first thing that needs to be done is to install your AutoDesk MotionBuilder software on your PC, Mac or notebook. Then, launch the program and open a new project or the project you want to work on. You will notice there are a lot of windows opened inside your program, and that is because each window is another application or effect you can use.
Resize them and make them bigger or smaller to suit your needs. You can save them in your Layout by simply going to the top menu, select Layout and click Create (New) Layout. This will help you whenever you need to add effects to your project.
Character Animation: Skeletons
Character Animation is another feature of AutoDesk MotionBuilder software. You can animate characters by manually setting the key frames. But first, import a mesh (a model) and define his bone system and skeleton features. After doing so, right-click the skeleton region and select the Isolate Section, then Select by Name on your main tool menu. In your Select by Scene box choose Display -> Children, then Display -> Expand all. This helps you by naming each bone of the skeleton and then later characterizing them by just one simple click. If you wish to use more skeletons, then repeat these steps.
