I want to do paths and roads and I find with a standard brush they will always come out messy. It would be really nice to have nice curves and such but pure spine based brushing.
You just maybe paint your shape and it would show maybe an overlay and not actually pain it what it would sort of look like when applied.
Thanks 
There are several spline tools on the asset store. I have one I’ve written that I plan on releasing for free on the asset store at some point.
Its just a tool for building a spline with different nodes, branches, etc. Each node can have different widths and stuff, but you have to do the “work” yourself after the spline is built. That’s done by traversing the node tree and doing whatever it is that you want to do.
I use MegaShapes for my tracks, it is the most advanced lofter I have found, and has some handy features such as matching a terrain to the loft, conforming the loft to the ground and carving out terrains.
