Can I make a Material, or its containing folder, 'Read-Only'.

Hi,

I would like to know if there is a way to ‘lock’ Materials from being changed in the editor. I would like to be able to create and edit Material Instances from them, but I don’t want anyone to be able to go into the actual Material Blueprint to change anything.

Is there a way to make the material ‘Read-only’ or lock the folder they are in?

And yes… I know I should be able to just ask people not to mess around in the Blueprints. But they won’t listen.

Thanks in advance for any suggestions!
