Landscape layer

The island in the above screenshot is rendered with the landscape layer.

What can I do with the landscape layer?

With the landscape layer you can render landscapes.

How do I create a landscape layer?

Choose LAYER > Add layer > Add landscape layer... to create a new landscape layer.

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

Examples

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

Displacementmaps

The landscape renders displacementmaps (heightmaps) generated by apps like:

16 bits displacementmaps

Make sure to export the displacementmaps as 16 bits.

8 bits displacementmaps

With 8 bits displacementmaps the surface is not smooth. The limited height resolution creates terracing.

Effects

The landscape layer needs a displacementmap effect. The following effects can be used:

  • Effects/Displacementmap
  • Effects/AdvancedMaterials/ColourmapDisplacementmapCubemap
  • Effects/AdvancedMaterials/ColourmapDisplacementmapReflectionmap

Hardware tessellation

BluffTitler uses DirectX 11 hardware tessellation. This makes low details visible. You can control the amount of tessellation with the FX Displacement detail (tessellation) property. A low value looks like this.


Multitexturing

The best results are achieved by combining displacementmapping with colourmapping. Without a colourmap, the landscape looks like this.

Standing in the landscape

Choose LAYER > Stand in landscape to make your layer stand in the landscape. The vertical position is now relative to the landscape surface.


Landscape layer properties

Position

The position of the landscape.


Size

The size of the landscape.


Colour

The colour of the landscape.


Specular colour

The specular colour of the landscape.


Specularity

The size of the specular highlights.


Transparency

The transparency of the landscape.


Texture repeat

The number of times the texture is repeated.


Depth bias

This property can be used to solve sorting problems. When the water and landscape layers are placed at the exact same position, you can force the transparent water to be rendered on top of the landscape by setting the Depth bias property of the landscape to 1.


Tripod size

A higher value makes the rotation of layers standing in the landscape (using the LAYER > Stand in landscape menu item) less sensitive to small details.
