Flipbook for a sequence of 3d objects

Hi all,
I am new to Unreal Engine. I have a sequence of obj objects

walkAnim.0001.obj
walkAnim.0002.obj
walkAnim.0003.obj

Imported them into Unreal Engine and hoping to flip through them by animating their visibility one at a frame time.

How this can be done using Blueprint scripting, what would be the nodes needed for a task like this?

thanks for the help
