Well i don't want to dissmiss you as a conspiracy theorist with out giving you a chance to prove your point. I posted a random screenshot earlier from that Odyssey Screenshot threat.Every landable planet uses repeating terrain tiles, what FDev call "terrain shapes generated offline". I've visited well over 100 landables so far and it only takes a few seconds on the way to the surface to see the repeating terrain, although many can be seen from high orbit. They range in size from a few hundred metres, to a few hundred kilometres.
I'd dearly love for someone to find a landable planet with no repeating terrain, but since this is FDev's new planet tech, I don't hold out hopes. It's not like they'd use the new tech for only some landables, but the old horizon tech for others.
Can you spot repeating terrain textures in here?
