https://planetside.co.uk/forums/index.php?msg=272466As a reply on something Matt said about using a plane for terrain, but then lacking the curve of the planet, I thought of a way to have the cake and eat it too.
Solution:
A round simple shape with a gradient displacement under a plane.
I tried it with several smaller planes next to each other.
You can place your planes wherever you want above it, and they'll have matching curvatures.
But then I thought and tested some more:
A simple shape with the same size as the plane, with displacement edge set to 1, it looks like sliced blocks of clay.
