Sorry, I am no native English speaker and neither am I a programmer - thus I am not able to express myself as clearly as I want to. Btw, I did everything in Blueprints. I will simply add three screenshots.
The first one shows the procedural terrain in an early state. As you can see near to the camera, the whole terrain is made of Hexa-tiles, but they fit together since they all use the same material and perlin noise.
The second one shows the procedurally generated landscapes correctly wrapped around the sphere.
The last one finally is the procedurally generated grid, I used for positioning the tiles, but also for the water-surface.
At the end, even with the LOD-System working, the performance was very bad. But I was very impressed with what is possible within blueprints with some basic logic and maths.
