I'm hoping there is an easy fix to get this working... like a BP setup that I can create or reassigning drivers for the morphs to drive the wrinkles? So far, I can't figure it out.
The wrinkle system is not importing correctly into Unreal Engine 5. I'm in Version: 5.3.2-29314046+++UE5+Release-5.3 and Character Creator Version 4.4.2509.1 using the Unreal Auto Setup version 1.33 for 5.3.
When I look at the Std_Skin_Head_HQ_Inst material, it looks to have all the relevant wrinkle information but no morphs are driving any wrinkles and importing animation files from CC4 also does not drive any wrinkles on the character. They seem to be working fine in CC4 and I've exported to Blender using CC4 Blender Pipeline Plugin 2.0.2 which works fine (the wrinkles in Blender are driven by morph/shape keys as expected). I've tried with multiple characters including the default male that I see in other people's tests. Let me know if you need any other info.
This is an image of the shader with all the wrinkle maps.. everything looks fine there as far as I can tell...
