Changing Static Mesh Actor Blueprint Materials using UMG

Hi,

What I’m trying to achieve is the ability to change the paint colours on a car blueprint using UMG buttons.

I have built the car using a static mesh actor blueprint and added a couple of buttons into a UMG blueprint.

I’ve tried adding some Set Material nodes to the Static Mesh actor blue print but it’s not working because something is either wrong or incomplete.

My main questions is how should this be properly setup? Should this all be done in the UMG blueprint or do both the UMG and Static Mesh Actor Blueprint for the car need to be setup?

I’ll include some images of my current progress.

Thanks a lot
