I've been using CC3 to create some poses and I would like to be able to use/see/reference/(reuse on other characters?) those poses in UE4. Is there a way to do this? Can they either be exported as separate fbx "movements" that could be applied to a character? Or is it possible to assign different poses different timeline places (so that as you use time 0 as the reference pose for binding, you could access time1 for one pose, time 2 for another, &c.)?

works both :

1.  So , you have to export your Character "Mesh and Motion" , in "Include Motion" menu tick "custom" , add your poses , now , thats important , the first pose in the list has to be "_OpenA_UE4" , you can find it under "Documents/Reallusion/Template/Character Creator 3 Template/Motion"....import to UE4 , tick " Use T0 As Ref Pose" -" Import Morph Targets" (when you have facial poses) , tick import Animations "exported time". You will get all your poses inside the folder with the Character with textures .. worx fine here .

Amazing, thanks! Seems that if you pick the UE default skeleton when importing those poses can be applied to any model with the same skeleton to boot.
