Do some H&H updates only work with a new seed?

[Aku]

This is a question for the devs. I hear opinions on it, but I would like a definitive, "yes, this is what you will not see/do in your old world." I saw all the pop-ups for the many things I can craft now. If all the resources are out there in unexplored biomes then I will keep going in my current world to save a ton of time. If that is not the case, I will need to start a new seed.

so far ive found all the new stuff in my old world. so it looks like the answer is no. but i'll personally start a new world once im done playing around

No, there is a interview on their youtube site called Fireside Chat were they talk about that, new stuff in biodomes can only appear in "none already explored" biodome. if I understood it right.

i just checked guy! gotta be a new world since the tar pits doesnt seem to be showing on the plains biome!

In places that have already been generated, you will not see new resources that aren't already spawning. EXs:

You WILL get deer meat because deer spawn like normal.

You will NOT get tar, because tar spawns at tar pits and those didn't exist prior to the update.

If you want to get tar, for example, you will have to visit a completely unexplored part of the map with a plains biome. It will generate then. Completely unexplored means never generated. So if another player visited it, it counts as generated and won't spawn tar pits even if it's unexplored on your map.

EDIT: It goes without saying that a completely newly generated map will spawn all new resources as intended.

Sounds good to me. I have at least 85% of the landmass unexplored so there will be plenty of resources, thanks.

There was a dev interview the other day. You can use the old seed but you need to completely restart everything.

That doesn't make sense, restarting means a new seed. What does restarting your old seed even mean? From what I read above, a biome generates when you visit it for the first time, and if you visit a biome for the first time in your old world, it should generate with all the new stuff. I have a ton of unexplored biomes in my old world, most of my world is covered in a fog of war.

That is not what they said. During the fireside chat the devs said it just needs to be unexplored areas, and that explored goes further than what you see as revealed on the map, the explored is anywhere within 500 meters of where the player has been.
So as long as you have substantial areas you haven't been anywhere near the new stuff can still generate.
