![]() To create a Null object in the centre of the scene, switch to Schematic view (Ctrl+w) and drag a Null object from the Asset Browser in to the Viewer close to the objects you are going to parent to it. Parenting the environment objects under a Null will allow you to easily position and scale them in the scene If the environment geometry wasn’t parented under a locator before it was exported, this can be done inside MotionBuilder. To remove any animation from the file, right-click in the Animation column and select Discard All Animation from the menu or individual takes can be omitted by left-clicking the tick in the Import column next to the take. Any elements you don’t want to include can be discarded by left-clicking in the Element column next to the item you want to discard until a red circle with a line through appears. ![]() Using the Open/Merge Options window allows you to specify which scene elements and animation data will be loaded. To open the file as a new scene use File>Open… or to merge the geometry into an existing scene use File>Merge… The Open/Merge Option window (described below) allows you to specify exactly what is included in the file. The exported environment geometry can be opened as a new scene or merged into an existing MotionBuilder scene. ![]() Begin by opening a new session of MotionBuilder or start a new scene using File>New. Next we’ll look at how to get the geometry you’ve exported into MotionBuilder and set it up in a way that makes it easier to work with and manage. To use this option, turn on File Type Specific Options>Include>Embed Media>Embed Media in the FBX exporter window. This option should only be necessary if the exported FBX file will NOT be used on your local machine, requiring the paths to the textured to change. This will “embed” all the textures in the scene into a fbm folder with the same name and export path as the exported Geometry. If you are only exporting geometry it may help to turn off Animation, Cameras and Lights in the File Type Specific Options>Include drop downs. In most instances the standard export presets “Autodesk Media & Entertainment” and “Autodesk MotionBuilder” will work for exporting files to MotionBuilder. Using the fbx plugin exporter, export the entire scene to MotionBuilder using File>Export All… or select and export specific objects using File>Export Selection… Rename the locator to something more appropriate so its easily identifiable in the scene. Parent any individual environment objects under a single locator so they can be easily positioned and rescaled inside MotionBuilder. Be careful not to combine any geometry you may want to reposition once inside MotionBuilder. Before exporting your environment geometry to MotionBuilder, combine the individual geometry objects into a single mesh to help improve the performance of the scene in MotionBuilder. Combine the geometry into a single mesh.This may mean you’ll need to do a little digging around to find the correct menu or object name in your 3D program. I’ve tried to make the following steps as non-software specific as possible so they apply to any 3D package. There’s also a video tutorial showing “How to Use MotionBuilder Story Tool to Create a Cut Scene”. The Story Tool allows you to create complex animated sequences using multiple characters and motion capture clips and then reposition, edit and blend them, in a similar way to video editing software. This tutorial will explain how to use the MotionBuilder Story Tool to create an animated cut-scenes or pre-vis sequences. I will guide you through every step of the process from importing your characters and environment into MotionBuilder and animating them using the Story Tool to plotting and saving the finished animation. ![]()
