1 year ago Well, I’m guessing there’s something going wrong with calculating the lowest overall elevation. From memory, I think I grit the elevation min() of all tiles and use that the bottom for all tiles. Does this all happen for say just 2 x 2 tiles?

Hey Chris,
I seem to be getting misaligned tiles when generating.
