Use strings model for interpolation

Select this checkbox if you want height interpolation to make use of road strings (when Generate type is set to Strings) and terrain strings (if there are child strings). Heights at these places will be interpolated from the strings model rather than the specified surface.

This option is disabled if there are no visible road strings or terrain strings to use.

On click
