Colourmap layer

The monitor in the above video is a picture layer using a texture created by a colourmap layer. By pasting another show inside the colourmap layer (press <Ctrl> M), you can play a show inside a show. The template comes with BixPack 1.

What can I do with the colourmap layer?

With the colourmap layer you can generate colourmap textures for use in other layers.

How do I add a colourmap layer?

Choose LAYER > Add layer > Add colourmap layer... to add a new colourmap layer.

The new colourmap layer can be selected from the layers dropdown to make it the active layer.


The installer comes with shows demonstrating the possibilities of the colourmap layer. Choose FILE > Open show... and select a show from the BluffTitler/Media/Shows/Colourmap folder.

To quickly switch between your own shows and the ones that came with the installer, click on the Personal and App buttons in the upper right corner of the file dialog.

The colourmap layer creates a colourmap

The colourmap layer does not render anything. Instead, it creates a colourmap texture in memory that can be used by other layers.

Any effect that can use a colourmap, can also use the output of a colourmap layer. Examples are:

  • Effects/Lightened
  • Effects/NotLightened
  • All effects in the Effects/Filters folder

How do I make my layer use a colourmap layer?

Click on the Select colourmap layer button in the Change textures and effect dialog.

Show inside a show

A colourmap layer is like a show inside a show. The only difference is that the output is not rendered to screen, but to a texture.

Attaching a new layer to an existing colourmap layer

Make the colourmap layer the active layer before creating the new layer.

Attaching an existing layer to an existing colourmap layer

Choose LAYER > Attach layer > Attach active layer.

Import show

Make the colourmap layer the active layer and press <Ctrl> M to import a show inside the colourmap layer.

Export as show

Press <Ctrl> B to turn the active colourmap layer into a show. After that it can be saved with FILE > Save show as....

Clear colourmap layer

Make the colourmap layer the active layer and click on the Delete all active layers button to clear the colourmap layer.

Inspect colourmap

The generated colourmap is rendered in the top right of the screen when you choose SETTINGS > Render info.

Colourmap layer style 1


The colourmap layer generates an LDR texture (1 byte per colour component).


The colourmap layer generates an HDR texture (2 bytes per colour component). This can be necessary to prevent the terracing effect when the colourmap is used as a displacementmap.

Colourmap layer properties


The resolution of the texture that is generated. A higher resolution looks better, but requires more memory and is slower.
