Hello.
I have a workflow of Daz3d Genesis 3 and 9 characters to Maya 2025/2026 then export morph animations to Unreal. Morph animations, morph targets and bone animations import correctly in Unreal 5.4.4, but only the bone animation and morph targets import in in 5.6 or higher.
Import morph targets is checked and so is import animation. I tried it as import animation only and as a full character. In Maya I used the standard exporter, game exporter and in Maya 2025, send to unreal with no success in 5.6 or 5.73. Also tried FBX versions 2008 to 2020
