 Description   

 AFFECTS 1.17.40.

Intended generation: cold taiga M generates with a layer of snow coating the biome

Instead generates as: random chunks on the biome's edge have no snow generated in cold taiga M, being a pest when you're in the snow biomes.

Whenever I fly in a cold ice biome, part of the cold taiga generates with no snow. If I use an external program to view biomes, it is entirely the cold taiga M. Some chunk generation generates strange snow boundaries as well as hills in the biome. It does snow correctly though.

I generated it in version 1.2, used MCPE viz, read only, to view biomes. Regenerated it in 1.2 and is still not generating correctly.

Without an F3 menu screen, hard to reproduce bug since I can't view the biome I am in in the base game. You have to use an external program.

I regenerated the seed in 1.2 went out, back in, found the biome, still bugged. No mods, nothing, only the base game.

Seed 306959825, coords X-1000 Z800

Steps to reproduce

1. Generate a seed with a cold taiga M, you can use seed above
2. TP to coords shown above, or find a cold Taiga M
3. Use dev tool or external program to view biomes (generate and save terrain!)

Resolved as Cannot Reproduce because

  • this report hasn't been updated since October 2021, and
  • it was after that date that the Caves & Cliffs update introduced new logic for blending the edges of biomes together, so whatever bug might have existed in the old logic might not exist any more.

this is a duplicate of MCPE-150476

 reproducing this every 2 weeks on the latest build, no one has fixed it

Is this report still valid? Can anyone reproduce this still?

Just uploaded a new picture (Ice Spike_Extreme Hills.png) of an Ice Spike Biome bordering an Extreme Hills M Biome with not all the chunks being properly decorated with snow in the Extreme Hills Biome. The seed and coordinates are in the picture itself.

 

From what I can tell, it appears that it is the Ice Spike Biome that is causing the chunks in the bordering biome to not be covered in snow blocks the correct way. Thus it is affecting Cold Taigas and Extreme Hills (and possibly other biomes as well) that are bordering an Ice Spike biome. Hopefully this helps finding the root cause of this bug easier.

 

(also affects 1.5.2)

All bedrock seeds can be recreated in Java Editions with the Cold, Warm, and Mushroom biomes being in the exact same coordinates. Only neutral biomes will be in a completely different location such as Roofed Forests or Swamps.

For all positive number Bedrock seeds, you can use them exactly as is in Java edition to get the same biome layout. For all negative number Bedrock seeds, add 4294967296 to that negative number and use the new number in Java. This means because the seed used for by Delvin4519 is a positive number seed in Bedrock, he is able to use that same seed in Biome viewing programs for Java edition to find how the cold biomes generated in Bedrock.

As an example, the seed 1221723105 generates a godly rare Mesa Bryce/Ice Spike/Mushroom combo at -1111, 64, -600. Since it is a positive number, we can use the seed straight into in Java edition and can find that exact combo at the same location.

Another example is -1785205033 which generates a Mesa Bryce/Jungle combo at 730, 73, 580 in Bedrock Edition. Because that seed is negative in Bedrock, add 4294967296 to the seed to get 2509762263 and use that new seed in Java Edition to get the same Mesa Bryce/Jungle combo in the exact same coordinate.

Due to this, we can check the biome layout for any Bedrock seed on any Java biome finder program except for neutral temperature biomes. Hope this helps!

I don't think that seeds are the same from Java to Bedrock. They are similar but I have seen many examples of biomes that are different in the seed maps and the Bedrock game.

I started the same seed multiple times and ended up with the same thing so it's not that Bedrock is broken it's just that it's not exactly the same as seed viewers that use Java in order to create the seed.

I added a picture called Seed_Cudbullsec.png that shows this bug. There are many chunks without snow on the edge of the Cold Taiga biome which makes it look very weird. Again, to test my example in person, use the seed Cudbullsec (number form is 1415793676) and go to the coordinate of 500, 80, 940. This occurs both on my Windows 10 laptop and on my iPhone SE.

After looking at the Ice Spike seeds that I shared online in the past, this bug seems to be happen whenever an Ice Spike biome touches the Cold Taiga Biome. I'll have to check other biome combos to see if this occurs elsewhere too.
