Replacing Textures to Change Landscape

The Height Map Terrain templates in iClone Terrain library are designed with different seasons and scenarios. However, you can change them by simply replacing the textures the terrains are given, while the landforms will remain unchanged.

Please note that the landscape of each embedded Height Map Terrain template is composed of 4 different materials, in which each material contains three texture channels: Diffuse, Detail and Bump.

The distribution for the four materials are defined by another mask image in PNG format (Please note that the illustration below shows partial areas of the entire mask image.

Please note that you can not open this mask image and edit in any image editor because the result will be unpredictable.

Changing Texture of Height Map Terrain

1. Load a Height Map Terrain template from the Content Manager >> Set tab >> Terrain library >> Height Map_Large library as a base.
   
2. In this case, the Volcanic Rock is applied.
   
3. Select the terrain in the Scene Manager, and switch the Modify panel to the Material tab.
   
4. Select one of the materials that contains the texture map you want to replace from the material list.
   
   You may also press down the Picker button and then click on the terrain to retrieve the target material.
   
5. The three textures in the material will be retrieved and display in the thumbnails in the Texture Settings section.
   
6. The areas affected by this material are defined in the mask image as shown below:
   
7. Double click on the Diffuse channel and load another image to replace the original one.
   
8. The lava area turns to water.
   
9. Repeat the same steps to the bank areas.
   
10. Replace the texture to create foam and sprays.
    
11. By adjusting the parameters in the Adjust Color section, you are able to re-define the texture color to change the season of the terrain. A volcano rocky land can turn into a meadow.

   Note:

   Each material template from the iClone Material Library includes Color Settings, Texture Channels, and pre-defined UV Tiling values. Please refer to the Loading and Saving Materials section for more information. Therefore, you may need to manually adjust the UV settings of the textures in the material to get the best result.
