Adding an Import color map node
The Import color map node imports a color map in the form of an image file that you can apply to a terrain generation node, a transformation node, or a composition node via the Apply color map node. The output terrain is the same terrain as the input terrain, but with a color map applied to it. The color map is preserved throughout the graph unless a new color map is applied.
To add a node, right-click in the Graph Editor and select Create Node > Import > Import color map.
Double click on the node to open its parameters:
Importing a color map
To import a color map:
Either:- Drag and drop the file into the File name field, click on the folder button and browse to the file you want to import, or type the directory of the file to import.
- Drag and drop the image directly into the Graph editor. A
pop-up dialog appears. Click whether you want to import the image
file as a terrain, mask, or color map.
If you have already saved your project, type just a file name or sub-directory and file name to import it from the same directory as your project. There is no need to type the file directory.
File names with Unicode characters are supported.

The minimum size supported is 16 x 16. The maximum size supported is 8K for the Instant Terra edition, and no limit for the Instant Terra Unlimited and Instant Terra Pro edition. An error message appears if your file is smaller or larger than the minimum and maximum sizes.
Linking an Import color map node
The Import color map links to an Apply color map node to apply the color map to a terrain generator..
In the example below, we import a .tif texture to apply it as a color map to a Perlin noise terrain generator.
For more information on color management see the Color management workflow.
