The third person template has orbiting camera set up. Zooming: have the EI set target value for the springarm and and have Tick fInterp to it. There’s probably dozens examples here on the forum and more on YT.
Your current setup does not have the execution wires connected, not sure if this is just WIP screenshot or the reault. But you will want to hook it up to Triggerred.
Another thing is input handling. Is this a possessed Pawn? Is input enabled?
