Face Mask
The Face Mask
effect maps a 2D texture to your face. The texture appears to be painted on your skin and contorts with facial movements. Great for full face masks but also can be used for realistic makeup.
Create the Face Mask
To create a Face Mask
object, first click the +
button in the Scene Hierarchy
panel. Then, select Face Mask
.
Adjust the Face Mask
If you haven't imported a texture into your project yet, select + -> Import Asset
from the Asset Browser
panel and select the texture you wish to import. Learn more in the Adding Content guide.
With the newly added Face Mask
object selected in the Scene Hierarchy
panel, you can modify its settings in the Inspector
panel. You can modify the texture used on the Face Mask
by opening the inline editor for the Main Material
field. Click on the Settings
button to the right of the field, then click on the Texture
field and assign it to your imported texture.
You can modify how the Face Mask
is applied by double-clicking on the object in the Scene Hierarchy
panel to open the Face Mask Editor
panel.
Adjust the anchor points in the Face Mask Editor
panel to map the texture to the face. These points anchor areas of the face to the inputted texture.
In the top left of the panel, you will find two button: Symmetrical Mode
and Reset Points
. Points are moved symmetrically by default. You can disable this by unchecking the Symmetrical Mode
button. Reset Points
will reset all the anchor points to the default positions.
At the top center of the panel, you will find two buttons which allows you to toggle which texture points you are modifying.
Texture
is how the Face Mask looks itself.Opacity
Texture expresses how the opacity of theTexture
changes. A white pixel value being opaque, and black being transparent.
To tune the Opacity Texture points, choose Opacity
from the two buttons at the top center of the panel. Align your anchor points to fit the Opacity Texture.
Every Face Mask
has a default Opacity Texture so you can ignore this step if you don't need a custom Opacity Texture.
Face Mask Helper Files
To help create your face mask, you can download the following files which contain PNGs and a PSD that can be used as a reference to draw your mask. Take a look at the Face Paint Template to learn more about how you can use the Face Mask, and this reference file.
Face Mask Settings
