Broken subsurface since UE5.3+

Hi,

using Unreal Engine autosetup has broken subsurface since UE5.3 (tested both on UE5.3 and 5.4).

Reproduction case:
1. Create UE5.3 project or newer
2. Install latest auto setup plugin for UE
3. Import character from CC with high quality
4a. Open model in preview panel/tab and observe the broken sss
4b. Put model in level, enable transmission on directional light and observe the broken sss

Happening across all characters, both UE5.3 and 5.4. Same characters but in UE5.0-5.2 doesn't have this problem

OS: Windows 11

Issue still exist, Directional Lights in ue5  with 'Transmission' enabled causes cc4 characters to glow from the inside out like a glowstick. 

Changing SSS settings in Unreal doesn't lessen the amount of Glow but only restricts where the glow happens, but it still looks extremely bad. 

PLEASE FIX

Hello, with the latest release of CC4.5 and Unreal Auto Setup 1.37, this issue does not occur when transferring characters to Unreal 5.3 and 5.4 in our environment.
Please check if the issue persists after updating to the latest versions, and if it does, kindly let us know.

Thank you.
Tina.
