Yes it is possible. Just use the "Normalized View Port Rect" setting of each camera, to set each camera to fill the portion of the screen that you want.

Simply create both cameras, and then - for example - a side-by-side view (split screen vertical) could be achieved by setting:

Left Camera - Normalized View Port Rect:

• X : 0
• Y : 0
• Width : 0.5
• Height : 1

Right Camera - Normalized View Port Rect:

• X : 0.5
• Y : 0
• Width 0.5
• Height 1

And a split screen horizontal view (one view on top of another) could be achieved with these settings:

Top Camera - Normalized View Port Rect:

• X : 0
• Y : 0.5
• Width : 1
• Height : 0.5

Bottom Camera - Normalized View Port Rect:

• X : 0
• Y : 0
• Width 1
• Height 0.5

as you see here : split camera , you need 2 cameras , and you modify values of the normalized view port

But why is the camera cannot be view when I start to play it? Only FPS camera view can be seen. The 2nd camera is not shown.

hi, you have a option to change the " depth " in the inspector, the higher the value will be drawn over the original view. eg, main cam depth = 1 , cam 2 depth = 2. Now both cameras should work.
