Eyes and hair objects not animating with Body of character

Hey guys,

The eyes and hair are separate objects to the body of my model. In Cinema 4D I animated an Idle state with the head swaying back and forth. Everything looked great. Now when I import the model and animation into Unity, the head sways perfectly, but the eyes and hair stay static, not attached to the head.

I tried Unity’s c4d importer plugin and exporting from c4d as an fxb - same result each time. I also tried to manually make the eyes and hair the children of the animating Body, but that has no effect either.

Am I just being stupid?

Thanks

attach the hair ect to the head bone then it will follow the animtaion
i dont see how that could fail if it does then try write a script so it follows the bone
