How to make it

• Create a new Editor Utility Blueprint in the content browser (In Editor Utilities)
• Pick the Asset Action Utility parent class
• Open the blueprint and in the Class Defaults add a new entry in the Supported Classes array and set it to the Static Mesh type.
• Add a new function, name it correctly as it will be displayed in the asset actions (you can also write a description in the function details, it will be showed on hover)
• Copy this code inside the function (here named BulkSetMaterial)
• The function input is named Materials and is of type Material Interface (Array) (We use Material Interface type so we can accept any type of material, such as Material Instance).
