Of course. Be aware that this is all in some kind of beta state. The end 
product will show a very different street surface texture.

<grin> Most of this has been solved at this moment, except for the clean 
lines of the buildings. Some degrading has still to be done on them.

This has been solved. For the close-up views a separate street surface 
is generated, following the height_field but level cross-streetwise. 
This is not an automatic process but modelled separately. Not so 
difficult to do as I use a high-resolution mesh copy of the local 
height_field for modelling purposes.

Simply by making a union of the street surface object and the 
height_field before trace()

A new street view is being rendered.

Thank you indeed. I have not finished exploring the possibilities.
