I think this thread belongs in the "Ideas for Ryzom" section not in support.
Atys is a magical planet. Each area has its own special properties. Mobs and homins who lived in a given environment since ancient times acquire a small amount of differences that stay with them even when they migrate to other lands. After migrating mobs can pick up natural impurities from the land the live in, This makes the materials slightly different , tho not in an easily discernible way. The race crafting plans are designed with these impurities in mind and you can only succeed with these plans with the proper materials.
