UNREAL 4 - How to get a mesh rotation bounds to update BP? image attached

Hi, im making a particle effect, it depends on a camera & mesh location and scale as trigger… it Works perfect! BUT… no idea how to get and connect mesh rotation, so, if i rotate the mesh “square” in Z (0,0,90) at the viewport, particles don´t update this Z rotation, they still think the square is at rotation 0,0,0 (BP rotation), because i was only able to get actor location and scale.

Please help with BP images, here is my BP. Thanks
