Modify existing Unreal 5 Blueprint Virtual Camera

I am using Vive controllers to track a camera in Unreal. Even though Unreal now comes with great virtual production tools, we created ours before UE had a solution, and have been improving it and upgrading it as new Unreal versions are released. The current version needs to have 2 issues solved. One of the issues has to do with using the vive trackers not just for position, but also to control zoom and focus. This is already working but the issue is that when attaching the 3 trackers onto a rig, tilting the rig affects the focus and zoom, so the position of the focus and zoom vive trackers needs to be subtracted from the main tracker that is used for position of the camera. The other issue has to do with smoothing the noise of the position tracker. Right now it is very sensitive and if I zoom, the noise is multiplied. A solid understanding of blueprinting is required. Thank you for your interest.
