When the camera zooms in, it takes forever. is there any way that it could go faster?
And I’m new to unreal engine 4. I’m trying it out because I used unity before and still kind of am.
Can someone tell me about camera issue I have?
Go to Edit > Editor Preferences, and in the Editor Preferences window go to Level Editor > Viewports > Controls. You’ll see a Mouse Scroll Camera Speed, which you can change to something else. Otherwise instead if using the mouse wheel, you could also use the W/A/S/D keys + right mouse button. 
Hey when then the camera zooms in it’s extremely slow. How can i fix this?
Take a look at my post above
