Unity3d - Exported Genesis 3 animations do not have working arms

Have created a number of Genesis 3 characters/animations that I want to Export and use in unity. Characters seem to export cleanly as FBX (then set to Humanoid rig), but the animations seem to be a hit or miss terms of whether the arms animation correctly or just stay in the t-pose position. I am able to retarget animations that I brought over from Mixamo to the characters and their arms work, although the face animations are terrible. Is there some trick to exporting out of Daz3D studio that I am missing for animations or something that I need to do in terms of rerigging in Unity3d, or is there some other program that might be better for animations than DAZ3d (I tried adobe Fuse but couldn't get the trial to start).
