Issue 12290
Bug: Utilities/CR_FaceExpRig
Hello,

I also encountered the same problem described here: https://discussions.reallusion.com/t/ue-auto-setup-1-41-is-released-now/15328/10

The game won't pack in Unreal Engine 5.5 and 5.6. There are no problems in the editor itself, but the game won't pack, reporting an error: Game/CC_Shaders/Utilities/CR_FaceExpRig.RigVMMemory_Work:RigVMModel___DISPATCH_RigVMDispatch_ArrayIterator_Element'. FallbackStruct structure.

Through trial and error, I discovered that the error occurs if the model is exported from CC4 or CC5 with a UE4 skeleton. There are no problems with a UE5 skeleton.

Here's what I did:

Created a new project in UE 5.5 - Third Person
Copied the Auto Setup plugin
Imported the model from CC4 with the UE4 skeleton
Placed the model into the game scene
After this, the project won't pack and will return an error
OS: Windows 11

I’m having the same exact issue and my project has been halted because of it. I even did the same and created a third person and used the UE5 and same issue. This is easy to replicate because it happens no matter how you import. please help us find the fix for game won't pack, reporting an error: Game/CC_Shaders/Utilities/CR_FaceExpRig.RigVMMemory_Work:RigVMModel___DISPATCH_RigVMDispatch_ArrayIterator_Element'. FallbackStruct structure.
