 Le tutoriel ci-dessous est basé sur le recours à un logiciel privateur car il s'agit du seul outil actuellement capable de réaliser toutes les opérations, grâce à un plugin dédié compilé spécialement pour lui. Nous espérons qu'un jour un outil libre pourra le remplacer dans la chaîne.

+Ryzom Forge (Ulukyn) ont réussis à ajouter une nouvelle zone, il semble. (Je n'ai pas tout à fait compris si c'est en partie basé sur des zones Nevrax ou complètement nouveau, en tout cas c'est plus que jusqu'à maintenant!) Alors si quelqu'un veut étudier les zones, faudrait essayer d'en discuter avec Ulukyn (et Kaetemi + sfb/esseffbee qui sont réapparus sur le canal #ryzom récemment)
