Pourquoi, on a un monde vide dans terragen ?
On pourrait pas avoir un monde pour creuser la terre plus facilement ?
Et, de l'eau créer automatiquement dans des zones creux de la terre ou dans les montagnes ?
Therefore, it was an empty world in terragen?
We could not have a world to dig more easily?
And water automatically create in hollow areas of the ground or in the montains ?
Excuse me, I may not fully understand the question you are asking. But it sounds like you want to do a flat, empty world and have your water/atmo erode it?
I'm not sure this is exactly possible. You may need to create this world via World Machine or something and export it to Terragen, and then play around with the keying on the displacement multipliers?
I'm still new myself, just from what I understand that is the advice I would give.
