In this Citizen tutorial we?re going to look at some of the techniques that went into the rendering of this Goldfish image. The main focus of the tutorial is how to set up the materials and lighting. We will also be doing some modeling, texture painting, using various methods to mix material shaders with the node editor, and finally setting up an HDR image to create some very realistic reflections.This is a great chance to learn more advanced tricks for getting what you want with Cycles. Including how to make use of the Ray Visibility options to control what is visible to the camera and in reflections, and other techniques. Check out the images below to see the original image, the final result of the tutorial. You will also find a free fish scales texture Josh created that is free to use in your own Blender scenes.
