Locking transparency

Jump to Mobile or Windows 10

What does Lock Transparency do and why use it? Lock Transparency creates a mask that locks out the transparent portion of the layer. This means that when applying paint, it only covers areas containing pixels (paint).

Picture a car with no background image. Use to make the background see-through, instead of white and opaque. This makes it easier to combine layers and blend pixels with various levels of opacity.

In the example below, I only wanted to paint on the car. With Lock Transparency on, I could paint the car without having to worry about painting white areas, like the windows, as well.
