You’ve created a material dynamic instance, but you have not set this newly created instance as a material for your mesh.

That is my problem. I want to change material of an actor in level, and I want to do it from HUD blueprint. I tried interface blueprint, didn’t work, than I created a blueprint with this actor as component and in HUD blueprint tried to get a reference to blueprint and component and change material directly. Did not work. My previous post Changing material of component in another blueprint - Blueprint - Epic Developer Community Forums

If you have any ideas please help. Thank you
