Field-of-view bug when resizing. It only decreases...

[keith_brown]

As can be seen in the gif it looks like I'm shrinking it which I'm not. I barely touches the mouse and it shrink no matter what. There's no way to increase the size again. It gets stuck and just resizes one way.

Any ideas? This happen at times. Super annoying 😞

What version of Max? Can you give a few more details like, what kind of viewport, what kind of mouse, any 3rd party plugins?

I've tried to reproduced the problem and can't find a pattern why this is happening.
- I'm using max 2024.

- Viewport no matter if it's the camera viewport or perspective.

- Dell basic mouse (never had a problem in any software before).

Third party Corona but nothing more than that.

What happens if you go to 'Customize/Preference Settings/Viewports/Display Drivers' and change the 'Choose Driver...' to 'Nitrous Software' or 'Legacy OpenGL?'  Restart and see if the anamoly continues. I don't mean leaving it on one of those permanently if it fixes it but it's more of a diagnostic.

Haven't encountered the problem again since I posted here. But when I stumble across this again I'll try your suggestions. Thanks!

Now I know! Happend again now.

When I adjusted Zoom Factor to whatever value it decided to bug out like my first gif show. Having it set to 1 works. Strange...

It's the Corona cam btw

So it sounds like a Corona integration bug not a flaw in Max per se. I'd go to the Corona forum and talk about it there. You'll likely have a better chance to solve it if the 'Zoom factor:' setting is still not working properly. 

Edit: FYI, it's always good to say in  the first post you make what version of Max and what major plugins you are using. If someone says, "Max won't work right, help" then there are 1000s of things that could cause that. But if someone says, "Max 2024 with Corona Camera is not Zooming properly" we know where to start looking for the culprit. I think this is a Chaos Group (Corona) issue. The developers over at Chaos are fantastic and I think you'll get the issue solved there if it still exists.
