I have a blueprint made up of several meshes that I’m trying to add textures to & I can’t figure out how to do it without without jumping through a mess of material override hoops. I need to make subtle tweaks to the materials in scene, so no, I don’t want to do it in my 3D program. Quick and easy material application & modification seem as basic a requirement inside an actor blueprint as being able to move and rotate the meshes inside the blueprint…no?
Are you talking about replacing or actually adding? If it’s replacing or setting. In your blueprint just get a reference to your mesh (for example Right click->Get Mesh), then drag off a wire and choose “Set Material” and fill in the index of the material in the mesh and the material to replace it with.
It was pretty simple actually…I’m new to game engines & this is probably so obvious to a lot of you that you wouldn’t even think to suggest it:). This was the root of ALL MY PROBLEMS & the reason I wasn’t using blueprints in my matinee sequence for my meshes. I was dragging materials onto my mesh in the the editor, then wondering why when I added it to the blueprint, the materials didn’t follow. All I had to do was double click on my mesh, drag the materials into the appropriate slots and save/compile. Now everything works great, I can use the blueprints just as I thought they were intended to be used (for actor blueprints)…
They’re meant to be used for a boat-load more then just actor blueprints 
I meant to say WHEN used for actor blueprints…
