Tyndale, I was baffled at first too when I first found the Israh tutorial. Fear not, it is a simple problem.
On the Fractal Terrains section of the tutorial concerning the Incise Flow Process, the TUTORIAL has the ORDER of the 4 fields different from the current version of Fractal Terrains.
The tutorial lists the values in this order (from left to right since that is how they are listed in the tutorial): Blur/Amount/Flow Exponent/Effect Blend
Fractal Terrains 3 has those same values, but when the little window for the Incise Flow Process opens the fields are in THIS order: Amount/Flow Exponent/Effect Blend/Blur.
You don't have to change anything the tutorial says to do EXCEPT put the numbers in the right order.
For example, in the tutorial it reads: Incise Flow: Select all, 8 / 1 / 0.5 / 1
So, as far as the tutorial is concerned, 8 = Blur, 1 = Amount, 0.5 = Flow Exponent, and 1 = Effect Blend.
In FT3, you would enter those values (from TOP to BOTTOM) in THIS ORDER: 1/0.5/1/8.
Hope that helps!
