I realized LostCity with Real 3D and my Amiga 4000/ 040 with 16 MB Ram. 
The whole picture has been realized with Real 3D V3 and Freeform v 1.9.  
The wonderful sky has been generated by Real 3D starting from a tiny 5 bit 
greyscale brush, using the excellent tutorial by Matthew Bell (found in the CD 
Rom 3D Arena) for creating sunsets. (I could create it using the scope handler 
as well, but the time to render would have been at least 3 times slower!).
The rendering (full ray-tracing) required around 2 hours, with these options:
 AA=3, LightSampl=3.
