Camera Look At Object in Sequencer

Hello. For my work I need a cinematic lookat camera to track a moving object in sequencer. Instead of using the rotation settings in Sequencer, the camera will translate along the path but always looks at a key object while both the lookat object and camera are both moving. This is intended to recreate a smooth stabilizing method for camera movement. I was able to make this work in an older version of UE4, but it broke and I can’t figure out how to fix it. BTW, this issue has nothing to do with spawnable/posessable objects. I tried with both spawnable and both possessable in 4.15.1 and neither method worked. Please help!

Did you try with the look at settings in the cinematic camera?
