I moved the bushes using the advance movement tool which can be toogled by pressing x.
Ya I know about that (should be the default moving behavior), but curving is still really hard to pull off imo.
And why not leave that segment of the track like it is?
This game looks great, but I just don't have the patience for it most of the time. I suppose I just lack the "vision" of what I want to make, so I just kinda meander ingame until I get bored.
It's actually a lot like Blockland; it can be tough at first so experiment with it by making crappy stuff until you've figured out how to make good stuff. Don't start with the sandbox, play through the career mode.
