I just discovered that instances in Unreal are white dots, instead of the small house.
And if you select more than one of those dots at the same time in the World Outliner, you don’t see the mesh assignment nor the materials assignment.
But worse, even if click just a single instance, and update the original static mesh, with a Datasmith import you don’t see any change until you click the little yellow icon next to the material for each and every instance.
Have I misunderstood something here? I have about 100 of these lights, how do I make all instances respect the updated source mesh in one click?
