Fixed a bug that caused incomplete hidden property validation, which may mean you see some new “Illegal property override” warnings. If these warnings are on properties you need, then please report these to us so that we can consider exposing them to UEFN. These warnings will become errors in a future version of UEFN.

Step-by-Step Migration Process
- Prepare your projects: Ensure both your Unreal Engine and UEFN projects are open or easily accessible.
- Select assets: In Unreal Engine, navigate to the Content Browser and locate the static meshes, materials, or textures you wish to transfer. [1]
- Migrate: Right-click the selected files, hover over Asset Actions, and select Migrate. []
- Confirm dependencies: An Asset Report will pop up showing all connected files (like materials mapped to a mesh). Click OK. [1]
- Set destination: Browse your computer to locate the root directory of your UEFN project . Select the folder path ending in
...\Plugins\MyProjectContentand click Select Folder. [1, 2]
