Cinema 4D Character Animation

Ok i managed to get rid of the missing bones error by creating a root joint in cinema and adding it to joint list of the skin tag. Then clicked on create bind pose in the skin tag and imported the fbx of it to UE4 with T0 as reference. Now UE4 seems to take my joints but it still doesnt get the bind pose.
What is wrong?

funny thing i just discovered:
When i import an animation made with joints that were created by motion capturing i get the same errors but it works perfect nonetheless.
The animation i struggle with are generated by a plugin called easy walker, it drives the joints by xpresso i guess.
Might that be the problem?
