Summary

Using the MF_FortniteGameplay Material Function on a custom material causes the material to invalidate. When using this function within an instance of the FortniteBase_Parent material however, the material validates just fine. This also affects custom materials using the node when used with a TextureData asset.

Steps to Reproduce

Create a custom material with Use Material Attributes enabled, and plug the FortniteGameplay into the final node.

Expected Result

The material should validate correctly and be able to be used ingame.

Observed Result

The material does not properly validate and prevents the project from updating.
