We have been working on a plugin for UE4 allowing to export characters animated with Golaem in Maya to Unreal and to keep the link between them. Any update done in Maya will be reflected in Unreal.
The exchange is based on our procedural format, meaning that you do not need to export loads of geometry, but a small simulation cache.
We made a short video overview about it.
We would love to hear what you think about it.
