How layers are merged

Within a multi-layered fractal, Ultra Fractal merges the different layers to create the resulting image. This image appears in the fractal window. The layers are merged by superimposing them.

Ultra Fractal starts with the bottom layer and places the second layer on top of it. The third layer (if any) is in turn placed on top of the result, and so on. If a layer is completely opaque, the layers below it will be hidden. If a layer is completely transparent, it will not be visible.

Most layers will be more or less transparent, so they are visible while still allowing the lower layers to shine through. There are four ways to make layers transparent:

Of course, you can freely mix these options. It is common, for example, to use a merge mode like Hard Light and set the opacity to less than 100%.
