[kfarr]

the hash striping is too dense and does not match the other roadway striping from north america / california

There could be space in stencils atlas on the right center side to include a repeatable chevron shape (like 2 or 3 "V" characters on top of each other). The application can use either the entire width with the "V" or just the left or right sides with repeating hashes oriented left or right as needed for the street segment.

#455

[kfarr]

this fix caused a regression on existing scenes, the divider segment appears as a white box with no texture

Also old scenes cannot be remixed and saved, there is an error.

I guess it's because of "hatched-base" and "hatched-normal" not available. So I have attempted to add those back to see if it fixes the bug. If not we'll have to revert back to pre dist

[kfarr]

resolved but caused regression, more info here: #457
