Using the the Segmentation Processor patch group

First, create a project using hair, person or skin segmentation. For support, see our article on segmentation effects.

We have made a simple effect that uses person segmentation to seperate the user from a pink background:

To add the Segmentation Processor patch group:

1. In the Assets panel, select the segmentation texture.
2. In the Inspector, underneath Render Pipeline, click Create.

This will add two new patches to your patch graph:

The Segmentation Processor patch contains two values that we can edit to change our effect:

• Edge Softness - Increasing this value makes the outer edge of your segmentation mask less crisp, which can sometimes help you to achieve a more natural look.
• Dilation Kernal Width - Increasing this value will grow the size of your segmentation mask texture, making it larger than the part of the body which has been segmented.

However, to have these values applied in our effect, we must first change the segmentation mask texture that is being used to one that has been created by our new patch group:

1. Find where your segmentation mask texture is being applied. Typically, it will be used as the Alpha texture of a material. You can click on the texture in the Asset panel to see a usage list.
2. In the Inspector, replace the texture with the new one created by the segmentation smoothing patch group. It will be called Segmentation Mask Texture.

You'll now see that adjusting the values in the Segmentation Processor patch changes how your effect looks.
