INFO: Using direct3D to Export Objects with Hierarchies
Last reviewed: July 30, 1997

The information in this article applies to:


 * Softimage 3D for IRIX, version 3.7
 * Softimage 3D for Windows NT, version 3.7

SUMMARY
The direct 3D exporter does support hierarchies, therefore allowing you to export a model that has separate objects that are parented. Before you export a model with hierarchies, you should consider the following information:


 * Use classical scaling, or freeze the scaling of every model if you are not using scaling animation, otherwise you will probably get some weird transformations.
 * If the parented elements are not animated you are better off merging them with the parent object; you will get fewer elements in your hierarchies, therefore giving you better performance because there are no useless computation done on these elements.
 * The direct3D exporter only supports one hierarchy at a time so if you want to export several, you should first parent them to a NULL.
