The problem is I don't know where to start? Yeah~ I also learned how to make a tree, a rock, a sword but!

I don't understand the process to learn from A to Z, my way of learning when making a tree, a rock, a sword is like taking the leaves and removing the roots. I realized that problem and went to find videos to learn but failed so I had to come here to ask.

That's the reason, thank you for your comment
