The 'Hull Texture' Node Group comes ready installed into the set of sample .blend files that showcase the texture.
If you wish to re-use the Node Group in other projects, some detailed instructions are here but generally:
- Go to File->Append in Blender.
- In the dialog box that appears, navigate to the 'Hull Texture Node Group.blend' file that needs to be downloaded to a local folder on your machine.
- Double-click the filename and you will go to a set of directories nested in the file. Double-click the 'NodeTree' directory:
- The Hull Texture Node Group should available. double click this to add it to the open project:
- You can permanently make the Node Group part of your standard blender setup by following the instructions here.
The Hull Texture Node Group looks like this:
It has the following parameters:
- Vector: This is used to control the UV Mapping, in other words, how the texture gets mapped onto an object. You can also control the scale, rotation and position of the texture through the standard Mapping node. An example set up might look like this:
- Color1/2/3: This allows you to control 3 levels of color for the node to give different variations. Another useful trick is to place a ColorRamp node after the Node Group to control the effect further:
- Size: Control the overall size of the effect.
...and that's about it!
