âšī¸The Runtime Data Asset
As of Unreal Engine 5, morph target data is no longer kept in the cooked build. Thus for Morph Tools to work in a packaged game, it requires a MorphToolsRuntimeDataAsset asset for all your meshes. these are easy to create, just right click your skeletal mesh -> Morph Tools Actions -> Generate Runtime Data Asset. This asset is a required parameter for many runtime functions. The asset is really just a container for morph target data that can be included in your cooked build so you can do morph target operations at runtime.
