Full procedural shader
This shader will allow you to set almost anything you want. Using a simple interface, you can easily create a pattern that will enhance the quality of your model. Shader does not require a hi poly model, it can be applied to any low-poly object. The surface shaping is created using the bump effect. Everything is 100% procedural, the skin color is fully editable, as well as the color of the stitching. With the help of two color inputs, it is possible to create the color of old faded leather with dark stitching or even a beautiful new surface in one color. At the same time, the intensity of the bump effect can be set from zero to deep stitching.
