Zooming too much makes object disappear in scene view

Unity 5.1.2f1, Yosemite

Just using the scroll wheel causes this :/

 

Have a look at your Main Camera's Near Clipping Plane value. You may need to make this value smaller.

You shouldn't really do this unless you have some specific need to do so though

Refer to the clip plane section of the camera manual:
http://docs.unity3d.com/Manual/class-Camera.html

edit: actually, you were referring to the Scene camera. The main camera's near clipping plane is only for the game camera.

Perhaps refer to this Unity Answers question

 

Crap, didn't know that!

It's a weird behavior for an editing view though, I thought it was a bug.

Thanks!
