Problem with movement in dollhouse-like camera 2.5D when changing cameras dynamically at runtime

Hey folks, recently I’ve switched engine from Unity and decided to give Unreal a go, having a blast so far.
Problem I can’t seem to figure out at the moment is related how camera angle works in my game.

So my game uses 2.5D camera style similar to Little Nightmares, but I’m also changing angles during runtime with a USCS plugin, but my movement doesnt adjust to that accordingly. So in the example below, this is what im trying to achieve but no luck so far.


So no matter which angle my camera is, movement should always be relative to the camera and not fixed. If anyone can help with a BP snippet with a explaination, that would be great! Cheers.
