Octane for Houdini

The Composite Texture node is used in conjunction with the Texture Layer nodes to combine textures in complex ways for various effects. In figure 1, a Checks and Color Squares node are blended together using the Blend Texture and Composite Texture nodes. An Adjust Hue node is connected to the Layer 2 pin on the Composite Texture node to adjust the hue of the Color Squares node.

Figure 1: A Texture Layer node structure example

The Composite Texture node can accept Blend Texture nodes on its Layer input pins. The connected textures through the use of the Blend Texture node, are layered from bottom up (1,2,3,etc.). The Opacity and Blend Mode on the Blend Texture node are used to reveal or blend the multiple texture layers together.
