Beta River Highway 1.7.2b

• Runway/airport overhaul
• Doubled the resolution of the terrain from 4K to 8K (grid size now 1m). Additionally remapped the world terrain vertical elevation for twice the apparent vertical resolution. Many roads are now smoother because of this but the rest still require additional touch-ups to maximise it.
• Converted terrain materials to PBR.
• Updated some road materials to PBR.
• Removed highway rest area spawn point, default spawn is now closer to the town at a fuel station.
• Improved ocean visuals.
• Improved quarry terrain.
• Cleanup of many roads (grass edge precision, road smoothness).
• Replaced river bridge near spawn with a new arch bridge.
• Added more fences.
• Scaled grass groundcover so it is smaller.
• Updated thumbnails
• Renamed many assets and reordered files.
• Deleted some old materials and textures.
