There’s an oilflow with hot oil running through all rectangles in my 3D object.
I want to show that in the first rectangle, from left to right, the oil goes from hot to a little less hot (from red to orange.)
Then, in the next rectangle, from right to left, the oil does the same, from red to orange.
And so on, untill the oil has reached the last rectangle.
What I should see on the 3D object is the following, per rectangle:
Red Red Red Orange = rectangle 1
Orange Red Red Red = rectangle 2
Red Red Red Orange = rectangle 3
Orange Red Red Red = rectangle 4
and so on…
