I’m not as knowledgeable on UE, this is a personal project I’m working on to learn so I’m not spending money on it.
But I’d think, based on what I do know, that asking the camera to rotate in respect to the pawn instead of the world wouldn’t be a huge ask? Or is the camera motion ‘baked’ into the stock 3P character controller? The one I’m working with is largely custom, I used the 3P as a template but deleted all the logic from it in the BP and started from scratch, so not relying on anything UE starts you with in that respect.
