This should work on a basic system. But, it introduces jittering and inconsistent pinch effect afterwards. To fix this, you need to store the initial and end location for each Touch index. Jitter can be reduced by using FInterpTo function accordingly.

Thanks I will look at that.
I have been looking at “gestures”
Under inputs in the project settings I created two gesture axis’ pinch and flick.
I do have a setup for using mouse wheel to move camera in and out and in Windows it works great.
So I was wondering if the setup below would work ???
Or do you still have to code it all out what comes after the gesture input nodes?
