For this homework, I chose to create a photo-realistic materials in Substance Designer. Following UIW 3D Animation and Game Design’s video (https://www.youtube.com/watch?v=sZhcQMwRNxY), I made a sci-fi panel and distressed it.
After learning, I found that it was very easy to make a NEW realistic material, but it was a very complicated process to make details and old material for a NEW material. Sometimes we can simply give it a texture, but more often we have to look at the details of the material in life to imitate the texture. In this way, we can give a texture from the real world to a model that does not exist in reality.
In the tutorial, the author starts with a simple graph and complicates it with basic Nodes such as Transformation, Symmetry and etc. Beyond the basics, he used Tile Sampler, Edge Detect and etc to give Grayscale’s graphics some random variations, and blend with some of the grayscale textures from Substance Designer’s texture library. Thats how the details come out. After obtaining a basic Grayscale image, he made three different layers based on this basic image, and then assigned different colors to each layers, so that each of them has its own hue.
These nodes look complicated, but actually I can understand how it is done. The tutorial explains clearly what to do in each step, which gives me a good understanding of how to use Substance Designer to create materials.
