When not using custom blueprint or C++ classes and just dragging a mesh into a scene, it creates an actor. There does not seem to be any way to control the tick of this actor. It’s just geometry that is controlled by custom components and no ticking is needed.
Does it tick? How can we be sure? Can it be disabled?
What about just placing an empty actor in the scene using the editor?
Static mesh actors don’t tick. Console command “dumpticks” will show objects registered to tick. BP actor added to level may be registered and tick if Can Ever Tick is enabled in class defaults. ‘Start with tick enabled’ is disabled if your actor may need to tick but won’t tick by default.
Depending on you UE version having an empty Tick event node in your BP event graph may cause an inadvertent tick to call. I think it’s fixed in 5.7
