So you’re beginning your search for a tutorial. Starting with Youtube of course, because watching video tutorials is much easier than going through a lot of text in written tutorials. Finally, you found a tutorial that seems to be about the exact thing you want to do. So click that play button!
Imagine yourself having a really cool idea for a CGI scene, which you probably had a lot of already. You think: Wow! This is gonna be awesome! So you open your favorite software (hopefully Blender) and start thinking about how you're going to make this new thing a reality. Speaking of reality: That's what's sinking in right about now. You realize that if you want to do this, it's going to take a long, very long time to make. Are you going to abandon this idea now, or are you going to try your darndest for many months and then finally give up? Because deep down you know you're gonna fail. Why? Because of every CG artist’s biggest enemy: Time. Yes, really. Think about it.
