Adding a Sub-material node

The Sub-material node creates a sub-material from a list of predefined sub-materials provided by Instant Terra. This node must then be connected to a Material node or an Advanced material node to provide a sub-material to a layer of a material, which can then be applied to terrain with an Apply material node.

 A sub-material contains a set of textures that correspond to a single effect, for example, a rock sub-material or a grass sub-material.

Below is an example of different sub-materials.

To add a Simple material node, right-click in the Graph Editor and select Create Node > Materials > Sub-material or press the keyboard shortcut NSBA (Node SuB Material).

Initially, no sub-material is selected, and the node is invalid:

Downloading sub-materials

Sub-materials are not installed by default. You need to download them.

  • The symbol indicates that the sub-material has not yet been downloaded.
  • The symbol indicates that the sub-material has already been downloaded and is on the user's hard drive.

If a sub-material that has not yet been downloaded is selected, the following window appears:

  • The Download the selected sub-material button allows you to download only the selected sub-material.
  • The Select the sub-materials to download button opens the window displaying the list of sub-materials again to select the sub-materials to download. Click on a sub-material to select it. A red cross then appears at the bottom right. Click a sub-material again to deselect it.



    Once the sub-materials to download have been selected, click OK.
  • Clicking on Download all sub-materials button downloads all the sub-materials that have not yet been downloaded.

Whichever option you choose, the download starts and a window displays the progress:

  • Clicking Cancel cancels the download.

Sub-materials already downloaded remain downloaded.

Editing the Sub-material node

Once a sub-material is selected, its name and a preview image appear in the window::

  • To choose another sub-material, click on the image.
  • If the Sub-material node is linked to a Material node, itself linked to an Apply material node, click to display in the 3D view the terrain to which is applied the material.
  • Click to return to the display of the sub-material.
  • The Size parameter adjusts the size of the sub-material.
