How to apply material to all actors on play

Hi all,

I am just wondering if it is possible to choose a material (I.E. from player menu) and apply it to all meshes in game?

To expand upon this, I want the user to be able to go into an options screen, choose red, blue, green (whatever) from the menu (done this), and then when they press “play game” their chosen color is assigned to each instance of static meshes / actorsin the game world?

Yes you can via material instance and material parameters too:

You can also set one instance to multiple meshes and control material paremeters in all of them as result

Thank you, problem solved.
