Hello, mappers!
I think we can all agree that TrackMania's map editor is awesome. It's simple, yet powerful. I've used it for multiple years now, and learned much about mapping as well as the tools the editor gives. I might not be a mapping legend, nor would I say that I know everything about the tools, but I feel like I have enough experience to properly teach others its functions.
Over the past few months, I've been working on a mapmaking guide. It's primarily tool-based; I mostly talk about what the tools do, not so much how to use them effectively. It's a long and fairly comprehensive guide of TrackMania's map editor, and it's finally done.
While it's aimed at new users, it also touches on some advanced topics such as blockmixing and the mediatracker. Give it a read; you might learn something new. These are Steam guides as well; since TM2 is divided into separate games on Steam, there's a different version for each environment. While each is essentially the same, certain environment specific topics might not appear in all versions. Likewise, the pictures shown are of the guide's environment. Each links to the example map shown in the guide, if you want to try them out yourself.
