With character cache, we can export some render contents easily and freely. But before version 3.5, it usually need some script work by TD.
For making your work more faster and easier, we provided some companion exporters in this new version.
Please notice these all exporter need install counterpart software. For example, the exporter of Alembic, your Maya should above 2013 and load abc cache plugin. Or if we're going to use the exporter for shave, you need install shave and mtoa plugins.
