I made an image with all ten digits on it, and used scaling and offset in the material room.

My image has ten digits, 0 through 9, left to right.

I make the image 10 times the area of the rectangle via Image_Map node U_Scale=10.

I move the digit I want into the rectangle via Image_Map node U_Offset = -x where x is the digit I want. For example, to show the digit 4, U_Offset = -4.

I think that is the easiest way to change the number via one dial.

Now can you think of how I changed all the numbers (all five digits) with ONE dial?
