I’ve seen in some tutorial images, to get the mouse in Unreal (instead of having it take control for you like a first person shooter), you can use Event Begin Play > SET (check show mouse cursor).
I cannot find that node for the life of me, and I don’t know what to search for, as set returns too many things, and set cursor returns nothing.
Easiest way is when you rightclick to get the context menu in Blueprint graph editor, untick the Context checkbox in the upper right corner. Then the set show mouse cursor node should show up. Remember to tick it again when you’re done.
