Good morning

First, sorry for my English

When I import characters from CC3.2 I export with face expression (maybe). But they see normal expression.

I apply face expression and I export to FBX. I need chenge something?

Have a nice day

Sorry but I do not use Unity so I cannot answer this.

They should show up as blendshapes I believe. Something like this:
 

Dorothy posted something that seems to possible address this same issue for me where it looks like unless you bake everything you won't get the facial expression you thought was being exported out of CC3:

She shows that for pre-canned facial animations you choose in CC3, you can create a new custom morph slider for those and then I guess just bake that into the model before exporting. 

I also figured out how to get the facial morph animations correctly to Unity 3D as well, described here (Export MotionPlus via Collect Clip in Timeline):
