I’m a freelance 3d designer.I use Maya in my work. Maya requires a 3 button mouse for panning(moving view of object). My old 3 button mouse which I used with Maya broke. When i tried to buy a new 3 button mouse, I found out that it is no longer widely available in stores. What is widely available is a scroll mouse, which I’m not sure if it works the same way in Maya
