If you have exported from Mixer to the standalone version of Bridge by using the Export To Library function, once your Mix is within the standalone version of Bridge, export to Unreal Engine 4. Doing so will result in the material setup being created for you. Once in Unreal Engine 4, you can migrate your material to Unreal Engine 5:
1) Create an asset in Mixer, then in the Export Tab, select Library as the Export Target (as shown below):
2) When you open the standalone version of Bridge, you'll see that the asset is now in the Mixer tab in your Local Library.
3) Create a new project in Unreal Engine 4 and export your Mix from the standalone version of Bridge.
4) Once the asset appears in your UE4 project, navigate to the asset from your Content Browser as shown below:
5) Right-click on the asset and navigate to Asset Actions > Migrate.
6) In the window that pops up, ensure all the textures you need are selected and select OK.
7) Select the location of the UE5 project where you'd like to send this asset. Make sure you've pointed this migration into the Content folder of your UE5 project.
8) Once you hit Select Folder, the asset will be migrated to the UE5 Project.
9) Open up the UE5 project, and the asset will now be within your Content folder.
