So how generated offline means handcrafted?
I didn't say it did. I suggested you replace that layman's term (which other people are using for simplicity) with "terrain shapes generated offline", ie. Dr. Ross's words.
It just means that this procgen is too complex for real time calculations, so they calculated it offline on powerful network of pcs. Its like pre rendering (blender, maya, 3ds max, etc) vs realtime rendering (games).
So you know what FDev are doing? Do you work there?
When Dr. Ross said that terrain in Odyssey is, "now generated offline into terrain shapes that we know are formed," it could mean a lot of things. Eg.
1. Using empirical data of actual planetary geology with post processing for variety.
2. Simulation of geological processes over appropriate epochs (eg. rivers and canyon formation).
3. Procgen using algorithms approximating known planetary geology.
4. Hand crafting.
5. <add an unknown number of other possibilities>
6. Any combination of the above.
