Thanks Thomas and Alain for your advices.
I am aware of the scaling problems and unfortunately i used some pretty akward
scaling rules, so i think i will code a script to rescale all items.

Since the scale is very high (20 = 1m) and provided that it is a scene with an
animation in mind (point of view of the driving post in the locomotive) the
translation vectors are large, and it poses problem with the size of the sky
dome of LightSys.

It seems clear now that rescaling is mandatory, and maybe it will even increase
parsing performance...

For the desert floor, i think of a f_wrinkle based isosurface and some rock
generating macro, and will use sparse vegetation everywhere.

Thanks !
