This render is a combination of four different materials. In the shader editor section, you will be able to explore, experiment and modify the parameters to obtain unique results and better understand how the nodes work. Through your experimentation, you will have the opportunity to learn advanced techniques that you can reuse in other projects, facilitating the reuse and adaptation of entire blocks of nodes. You will also discover how abstract animations of this type are structured, allowing you to acquire new methodologies. Instead of following long courses and hoping to obtain the desired result, you will have direct access to the Blender file. This file represents an opportunity and a starting point for your personal experiments, improving your skills in creating abstract and procedural renders. In this way, you will be able to best represent your visions in Blender, increasing your knowledge and skills. If you have any questions you can easily write to me.
