The Cosine Mix texture node is used for mixing two textures together with a cosine wave. It is similar to the Mix texture, though the difference between the Cosine mix texture and the Mix texture is more apparent when the amount slider is shifted towards 0 or 1. 



How to Use

Open the Node Editor and prepare the setup as seen in the image below. Here, two separate procedural textures are defined (marble and checks) and both are linked to the "Cosine Mix" node. An image texture is used for the amount slot. You can define any procedural, alpha, or image texture for the amount channel. If you define Alpha image, only alpha of your image will be mixed. This applies to all mix processes in Octane.
