RotatingMovement

I have an actor blueprint with three static meshes. Ive used Rotating Movement to move two of these meshes.

How can I stop the third moving?

P.S I dont want to put down separately and cant use actor component!

Rotating Movement has an internal value called UpdatedComponent, which is the component it rotates.
You can change the target component by calling SetUpdatedComponent().

If you want to prevent the root component to be used as UpdatedComponent for a short amount of time you should disable bAutoRegisterUpdatedComponent which is responsible for automatically grabbing the root component as UpdatedComponent on startup.

e.g. for blueprints
