Hello Mr. Song. Don’t worry about a specific context when approaching the learning, you’ll learn Blender basics and then tailor the tool to create anything you need. Much like a chef, he wont learn specifically how to make chicken, he will learn the ingredients, temperature control, cooking times, which seasoning goes with which and after the overall feel he’ll be able to tackle any dish he wishes. Blender is the same way, here on CG Cookie you’ll learn all the tools, the modeling, texturing, the artistry and composition, etc, and slowly you’ll be able to apply it to all and beyond your creativity. So go ahead and start the learning, the community here is fun and awesome. 🤘🏼
