Scripted 3Delight - Outline/Outline Compositor: How to use Fadeout?

FirePro9

When choosing the Scripted 3Delight renderer and either the Outline or Outline Compositor scripts, you get under Outlines a set of 4 controls for Fadeout that are applicable to Color ID, Normal & Depth. The 4 controls include: Fadeout Enable, Fadeout Near, Fadeout Far, and Fadeout Minwidth.  Does anyone know how exactly these 4 controls work?  I've played with them but still can't quite understand how to consistently use them.  Thanks.

You need to have big value in line width to see the fade in fx . You might be also checking your render size because line render value have different results depending on render size

Thanks for the tip Juvesatirani.  

I am thinking that the Fadeout Near and Fadeout Far are measured in cm from the camera focal point, allowing near objects to have a heavy outline and far objects have a thin outline.

Indeed . Depth outline is the perfect case if you want to see those Fadeout Near -Far FX. 

DAZ script outline really awesome for getting quick result.  Of course there are transparency problem but that easy to fix in Postwork

Correction, looks like Fadeout Near and Fadeout Far are measured in mm.  I created a scene with 5 cubes each 1-meter per side, focused the camera on the front surface of the middle cube.  Here are a couple of test renders showing the control settings:

Fadeout Minwidth seems to be some kind of multiplier.

Interesting that increasing the Depth Line Width with Depth Fadeout Enabled set to On, causes the number of "fadeout bands" to increase by the number set to line width.  For example, in first picture you see that with Depth Line Width set to 1 you have a gradient with black edge at front and black edge at back.  Change Depth Line Width to 3 and now in addition to front and back edges black you get 3 additional gradients in between.
