2D TextureMask

Creating a mask

To create a 2D mask in order to mask some parts of a 2D Layer A single 2D Layer Read More , right click on this layer and select menu Masks :


Select Placement mask Solid mask that has a 2D Placement Read More for example.

• This mask has 2D Placement Define a placement in 2D space Read More that can be changed (green circle) to get more advanced shapes.
• It also got Feather parameters that are illustrated here. You can change the feather link in order to manage the feather of each side of the mask independently (red circle).
• The feather exponent allows you to change the mask feather curve. This will be particularly effective when a mask is applied over Distort Modifiers Change pixels coordinates Read More .
• You can also change its scale mode (blue rectangle) in order to give it a value relative to the medias on which it is applied (scale factor) or absolute (size):

Note that two different elements are created:


In this example, Mask TextureMask a part of your image Read More designates the 2D modifier and Placement mask Solid mask that has a 2D Placement Read More designates the mask that is applied to this modifier.
Masks can also be grouped with a 2D Group mask Blend multiple 2D masks together Read More .

Multiple masks on a modifier

A 2D Modifier Modify a 2D image Read More can have multiple masks. To add a mask to a modifier, right click on that modifier and select menu Masks . to duplicate masks. In this example, multiple masks are added to the same Placement mask Solid mask that has a 2D Placement Read More modifier:

Note that, to build the example above faster, it is also possible to use [CTRL] + [D] to duplicate masks.

Masks and Distort modifiers

For most modifiers, the effect of masks consists in interpolating between unmodified pixel colors and modified pixel colors. Since Distort modifiers act on geometry rather than on color , they follow a different rule: for each pixel, the mask controls the amount of the geometric distortion applied to the pixel (from "not distorted" to "fully distorted" ).
As an example, consider 2D Transform Change pixels position using translate, scale and rotate parameters with Frame Wrap Modes Read More . In itself, this effect is nice but rather bounded. In combination with masks, the number of possible geometric distortions becomes very large. Here is a small sample of the kind of things you can obtain:

Scale transform with radial mask	Position transform with placement mask	Checkerboard transformed with the Mona Lisa picture as a Mask
With noise mask	With Polygonal Mask	With quantized noise mask

% vs px units to make precise masks

Do not forget if you want a precise mask that you can put Smode in pixels units and use mask size (absolute size) instead of scale factor (relative to the layer on which it is applied):
