When opening a blueprint graph, such as the event graph or a function that contains a lot of nodes, the view automatically zooms out to show the entire node graph. If you then try and zoom in straight away (as soon as you open the graph) you can’t. The zoom keeps trying to go back out to show the whole node graph.
I think the problem is that when you first open a large event graph or function graph, the editor plays a bit of an animation to zoom out smoothly. This animation seems to take a second or so to complete. So if you try zooming within the second (which I do a lot as I work pretty fast), then you are not letting the animation complete so it keeps trying to finish the zoom out animation and keeps snapping your zoom back out. It will do this for as long as you keep spinning the mouse scroll wheel to zoom in. I’ve been able to keep it stuck in this zooming loop for some 10 seconds just by continually spinning the mouse wheel.
The only thing you can do is then wait for it to finish its silly zoom out animation before you can zoom in and get to work. The animation only takes a couple of seconds to complete, but it is so frustrating when you think it is finished, so you start zooming only to realise it isn’t… the zoom animation resets… you wait another couple of seconds and try again… and oh no its not finished again… reset… wait a few seconds this time… ok now we can get to work. Very annoying when you are jumping around between multiple blueprint graphs trying to work quickly.
The solution: Remove the zoom animation. Just make it snap straight to whatever zoom level it wants to open at rather than smoothly animating to that zoom. Alternatively, cancel out of the animation if the user starts to zoom with their scroll wheel so the user can take over. Please fix this ASAP. It is driving me crazy!
