Zelda BotW has realistic puddles that form and dissipate from weather cycle

But are the puddles randomly generated or in fixed locations?

Will puddle sizes be different every time? Otherwise to me, it's not a big achievement if it's something scripted based on weather cycles.

In any case this very impressive, I don't think anybody done something similar in any game until now.
