Hello,
I’m currently encountering an issue in Unreal Engine 5.1 while attempting to modify material properties, such as changing or adding a parent material, using Unreal Headless Mode.
In the process, I’ve successfully initiated Unreal Headless Mode and managed to load assets. However, I’m encountering difficulties when attempting to manipulate these assets and save the changes. Interestingly, this process works seamlessly in Unreal Engine 4.27, but in Unreal Engine 5.1, it appears that the file is locked by the main thread.
The specific error message I’m receiving is:
Error: Message dialog closed, result: Ok, title: Packages Failed To Save, text: The following assets failed to save correctly
I’d appreciate any insights or suggestions you may have regarding this issue. Thank you!
