UE 5.8 Can't package with Metahuman and/or Take Recorder

General Issues and Bug Reporting (Unreal Engine)
, ,

Summary

Through the chain of plugin references, Metahumancharacter requires the Landmass plugin and Take Recorder uses the Virtualcamera plugin. Landmass and Virtualcamera both have references to assets marked as NeverCook that are causing cooking errors that prevent packaging in UE 5.8.1. This did not occur in UE 5.7.4.

Disabling the SkipEditorContent (“Project-Packaging” Exclude editor content when cooking = FALSE) doesn’t appear to help.

This occurs when packaging through both the new and old packaging UI in editor.

Steps to Reproduce

  1. Create a new C++ project or open a previous project in UE 5.8 (enable MetaHuman Core data)
  2. Open the Plugins and enable the MetaHuman Creator plugin and Take Recorder plugins (restart the editor)
  3. Create a Metahuman from a preset (I used Aera), assemble it, and place it in the level
  4. Add a VCam from the “Place Actors” menu (set enabled to false on the VCam in the details menu to escape the view)
  5. Save the level as something easy to remember
  6. Set projects default level saved level in step 5
  7. Package the project (tested in Windows 10 and 11)

Expected Result

Project should package without errors.

Observed Result

Numerous errors regarding references to assets marked Nevercook in plugins being included in the cook process. Cannot package the project.
