This parameter controls the layer visibility (it is more like an alpha value).

Example :

  • 0 means the layer is invisible,

  • 1 means the layer is visible.

How to show or hide a layer, or fade the effect of a blur?

In the Parameters Panel, look for an option labeled Opacity - this controls how much of the blended result of the layer is composited with the blend of the layers beneath it.

In other words, for a typical layer, this will ‘fade it out’. For a Blur Layer set to “Blend Method: Straight”, this will fade between the blurred version and the unblurred version of the canvas. If you want it to become less blurry, adjust the Blur Layer: Size.

If you want to affect multiple layers at the same time, you have several options:

  • You can Group Layer your layers and use the group’s Opacity Parameter,

  • Export one of the layers Opacity Parameter and Linking others layer’s Opacity Parameter,

  • Linking all layer’s Opacity Parameter. Select the layers you want to affect in the Layers Panel, right click to Opacity Parameter in the Parameters Panel and choose Link.
