Hello there.
I have a problem while opening different scenes within my project by accident. As I did save my project prior this problem, it did not return to its normal size as before
I’ll provide the picture on what I meaning.
Please let me know anything that I can do to fix this
(The little black dot is my project, can’t zoom at all)
Try selecting an object in the hierarchy, then move your mouse cursor over the scene view and press the “f” key. The sceneview should then zoom in on that object and set the sceneview camera settings to reasonably view things on that object’s general scale.
Thank you so much, its that’s simple made me kinda laugh to myself
Yeah, the same thing has happened to me a few times before.
