MotionBuilder supports models with Point caching, however, the support is view-only: you can see Point caches created in other packages, but cannot create or edit them in MotionBuilder.

A model’s Point cache files are stored in the Scene browser’s Deformers folder.

To deactivate a Point cache deformation:

1. In the Navigator window, expand the Deformers folder.
2. Double-click the Point Cache deformation.
3. In the Properties window, disable the Point Cache deformation’s Active option.

You cannot see FCurve information about vertices on the model, as the Point cache information streams directly from the .mc file.

Because Point caching overwrites the object’s other deformers, you are unable to modify an object’s skin in the Skins window.

If you are exporting from Maya or 3ds Max and activate the Split mesh for per-vertex normals option in the FBX Exporter window, this may create problems with Point caching.
