Let’s say I’m making a blueprint object that has a bunch of static mesh components. If I was doing this in editor, I’d drag a material onto the mesh and it’d change the material. I can’t seem to find a way to do that in the blueprint editor though.
I dont know if that is what you are looking for, but try the SetMaterial node…
You cant drag and drop it onto the mesh, but under the rendering tab you can change/add a material 
KVogler’s option would be incredibly tedious since I’m designing entire areas composed out of about 50 meshes. I was looking for something like the rendering tab. I guess it must be hidden by default so I couldnt find it heh.
What is tedious about having a variable for materials and using the construction script?
But as mentioned, there is always the details section of the editor…
