Texture Layer

The Texture Layer is a special map layer that adds an image as a flat map to the scene.

Creating a Texture Layer

A texture layer can be created in the following ways:

  1. A Texture is imported with File → Import... → Texture Import
  2. A new Texture layer is created with Layer → New Map Layer... → Texture

These actions trigger the Texture Dialog

 

Texture Dialog


 

Texture File: Choose an image from your workspace which will be used to texture the heightmap mesh. Normally this is a greyscale image. When a georeferenced image is selected, bounds are set automatically.

Bounds SIze: The Width and Height of the resulting texture in meters. When a georeferenced image is selected, this value is set automatically.

Bounds Offset: The location of the resulting texture in meters. When a georeferenced image is selected, this value is set automatically.
Note that the button left of X-Offset can be used to change the reference point for the texture's position.

 

Texture Layer in CityEngine scene

The new texture is added as a new layer in the scene editor. If the texture is not visible in the 3D viewport, right-click on the texture layer and choose Frame Layer.

Texture layers (like all map layers) can not be selected in the 3D viewport directly, but only via the scene editor.
