Re: [VMC] Conversion from Geant3 geometry.

Laurent,

Are you using the stand geant3 libs or a modified library?
Just before saving the rz file, could you print the list of volumes
print VOLU

It looks like the geant3 jvolum zebra structure is not sane.
I am afraid taht you will have to go deeper, compiling your application
+ geant3 in debug mode to see what happens.
