On mouse move: rotate when key is being held

hi everyone
*sorry if double-post as i submitted this question and it went missing

Can someone help me with the below

  • I am using a sample blueprint to rotate meshes when mouse move. At the moment, meshes are rotated horizontally around Y axis left<-> right on mouse move
  • What i’m after is a tweak to also give the ability to rotate meshes vertically / flip them around X axis when mouse move & a key being held (ALT key for example)

Would someone be able to help?
