Thanks for your reply,
Enabling camera lag doesnt solve the main issue of the purple sphere slighty moving up and down.
The purple sphere (CameraLookTarget) is at a fixed offset (Z value) aboive the ground and only follows the character on X and Y.
The SpringArm of the camera is attached to a camera anchor (CameraAnchor) which follows CameraLookTarget. This means the springarm movement is not dependent on the purple sphere but on CameraAnchor.
Enabling lag will only make this effect lag a bit but the slight movement of the purple sphere stays even tho the Z value is fixed.
I tried debugging the engine code and even their it keeps the same Z value when passing it into “Set World Location”
