As you can see in the video, I was simply trying to find an elegant way to connect the branching path to the main path.
However, since I had connected a path before but deleted it, there was a break in the curb left, which I thought I'd just touch up later, which I think is fair to expect to be able to do.
As it appears to be, it doesn't seem to let me just re-place that section of the main path to fill up the curb, it just stays there until it's used.
Though, really, you'd think it would just close up automatically when there's nothing attached, but it doesn't.
The only way I could get rid of that break is by connecting the branching path next to where the break was so it wouldn't connect at the open spot, then place a small piece to the curb-opening and delete it again so that the curb would become whole again. - However, when this happened during the recording of the video, that was totally by accident and I couldn't recreate that afterwards, which still left me without a workaround.
What's more is that, even if I connect it to that existing curb-break, as you can see in the video, I couldn't alter the path-width either.
Well, the part after the curb would change, but the curb-opening itself wouldn't be altered along with it.
Why isn't it just so that it changes along dynamically when placing new path so that it creates a smooth form to the connected paths?
I'm quite certain details like these could be improved. - That said, for now, am I missing the way to do it or is it really that finicky and stubborn?
(On a different note: Why does the tree-bark have a shiny surface? - Could be turned more matte/flat, perhaps it would even save a little on performance-cost. - It should look dry and it could even be darkened when raining. That would be a cool detail.)
