On 6:35 why did he choose that exact edge to add a crease to? Like why didn’t he choose the edge prior to it? And why did he grow the selection to that edge? I’m sorry for all of these questions, but I’m just trying to learn
I know what you're thinking, like how did he know what to do? Feels like a math formula, it's not very intuitive, and that's exactly it. When it comes to modeling that soccer ball, it's one of those specific cases where it's like figuring out a puzzle, it's not your straight up usual modeling, it's almost like a math problem. What you see modeling that ball is not going to be the normal way of modeling something, it's just an example, so don't worry about it. Those steps you need to follow is almost like a hack, a procedural way people have found on how to go about the ball, but it's not like you are ever going to see an object and approach the modeling that way. So again, don't worry, it's there so just you know the possibility, this is not how you usually model.
It's a lot of trial and error over many projects that will give you intuition on these things!
I grew the selection to the center of the crease between sections because otherwise the black that we apply for the material would have a gap in it and wouldn't reach all the way to the crease. Similar to that, I wanted the sharp part to run all the way to the center of the intersection, and that one was right in the intersection. It could have been any of those three similar edges though that radiate out. When you have these questions I would recommend trying them out and seeing what happens! Sometimes there are many ways to accomplish the same thing and it doesn't really matter, but other times you'll see how things turn out differently and then will get a better intuition as to why we did it that way.
