Advanced Water Parameters - Refraction

In optics, refraction occurs when light waves travel from the water with a given refractive index into the air with another. iClone simulates this phenomena on the water surface.

Before we start this section, it is important to adjust the Above Water Clarity which specifies the purity of the water.

The Above Water Clarity

1. Go to the Set/Water/Modify page. Scroll to the Advanced Water Parameters section.

2. Drag the Above Water Clarity slider. The higher the value is, the clearer the refraction becomes.

Above Water Clarity = 30

Above Water Clarity = 100

Refraction above the Water Surface

This parameter specifies how intense the refraction effect will be rendered when the camera is above water.

1. Go to the Set/Water/Modify page.

2. In the Display section, check the Refraction box.

3. Scroll up to the Refraction parameters.

4. If you intend to modify the refraction strength above the water surface, drag the Above Surface Strength slider.
   The higher the value is, the stronger the refraction shows when the camera is above the water.

5. Increase the Blur value so the refraction turns to be more vague.

Refraction = 0

Refraction = 100

Blur = 1

Refraction under the Water Surface

You may follow the same steps as above to adjust the refraction under the water surface. This time use the Under Water Strength slider.
