The background in the above screenshot is rendered with a few plasma layers. The template used is from BixPack 27.
With the plasma layer you can create colourful animated backgrounds.
Choose LAYER > Add layer > Add plasma layer... to add a new plasma layer.
Choose LAYER > Attach layer > Attach plasma to active layer... to attach a new plasma layer to the active layer.
The new plasma layer can be selected from the layers dropdown to make it the active layer.
The installer comes with shows demonstrating the possibilities of the plasma layer. Choose FILE > Open show... and select a show from the BluffTitler/Media/Shows/Plasma folder.
To quickly switch between your own shows and the ones that come with the installer, click on the Personal and App buttons in the upper right corner of the file dialog.
With the 1st layer style dropdown you can set the plasma style.
This example uses the Blobs style.
With the Density property you can set the amount of plasma elements.
The Radiation property controls the size of the elements.
Plasma layers are rendered with additive blending. This means that plasma layers are mixed.
This example uses 2 plasma layers.
In this example, the Effects/Filters/Circles effect is applied to the plasma layer.
Click on the Attach plasma to active layer... button. The 1st texture is now replaced by the plasma layer.
There are 2 ways to use a plasma layer as a displacementmap:
1) Attach a plasma layer to a picture layer that is using the Displacementmap effect.
2) Render the plasma layer as a child of a colourmap layer and use this colourmap layer as the displacementmap in a picture or landscape layer that is using a displacementmap effect.
For the best quality, select the HDR displacementmap style in the 2nd dropdown of the plasma layer. Make sure to use the HDR style in the colourmap layer as well.
You can make the plasma layer seamlessly looping by adapting the show duration to the plasma speed. For example when using a show duration of 10 seconds and a plasma speed of 0.1 it loops seamlessly. The formula is:
Show Duration * Plasma Speed = 1
Duration is the duration of the show in seconds that you can set with the FILE > Set show duration... menu item. Speed is the Speed property of the plasma layer. Here are some examples:
Make sure to unmark the Include last frame checkbox in the FILE > Export as video... dialog.
With the first layer style dropdown you can set the plasma style. The current version features the following styles:
The plasma layer generates an LDR texture (24 bpp RGB).
The plasma layer generates an HDR texture (16 bpp R). This can be necessary to prevent the terracing effect when the plasma layer is used as a displacementmap.
The position of the plasma layer
This sets the colour gradients. Not all styles use all 4 colours. Press <F3> for the standard colour dialog.
This controls the shape of the colour gradients
The number of plasma elements.
This sets the area in which the plasma elements move. A value of 1 makes them use the whole screen. 0 makes them stand still.
The speed of the plasma elements.
This sets the simulation time in seconds at the start of the show. This can be used to immediately jump to a nice effect without having to create a long show.
The radiation of the plasma elements. The 1st slider controls the minimum and the 2nd the maximum radiation.
The wave length of the radiation.
The size of the border.
The plasma elements are positioned randomly. You can use this property to use other random positions.
