This is an improvised tutorial. I am learning Godot and I am trying to "translate" some project from another gameengine to godot. Being able to create my own mesh objects in this new language was a big step. On one hand I wanted to share this experience, in case other viewers have the same issues, on the other hand I did not want to invest much time into a tutorial. So I decided to improvise one, if someone is interested.
I also realized AFTERWARDS that this microfone will never be used again.
If this video should get many viewers and feedback, I can imagen to create another real tutorial on the basics of creating meshes.
I know this approach of creating traintracks may not be ideal, but it is the method I came up with. This principle is also used to create vector arrows and pipes in my project.
