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:

G     

Reduce the opacity of the layer. By default, the opacity is set to 100%, making the layer 

fully opaque. Move the opacity slider to the left to make the active layer more transparent.

G     

Change the merge mode of the layer. By default, the merge mode is set to Normal. The 

other merge modes create special effects that allow lower layers to be partially visible even if 

the opacity of the layer is set to 100%. See 

Merge modes

.

G     

Make only parts of the layer transparent. The previous two options affect the entire layer. 

You can, however, also change the opacity of only certain areas in the layer. See 

Transparent layers

.

G     

Add a mask to the layer. The mask allows even more control over which areas of the layer 

will be transparent. 

See Masks

.

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%.
