did you use a config? do not use capital letters or spaces in your mod id possible: metalmaster metal_master

why?

1.12 is no longer supported on this forum. Please update to a modern version of Minecraft to receive support.

okay, that explains a lot, I was surprised that the log suddenly ends the error occurred in iceandfire mod, check if you use the latest version, if not update the mod if you use the latest version report the bug to the mod author

there are no errors in the log part you posted so the full log is required

is that the complete log?

./minecraft/logs/debug.log

1.10 is no longer supported on this forum. Please update to a modern version of Minecraft to receive support.

1.8 is no longer supported on this forum. Please update to a modern version of Minecraft to receive support.

after thinking about your problem, here are two possible ideas they you could help you you could create your own OverworldBiomeSource and register it with the Vanilla name or you could create your own OverworldBiomeSource and edit the overworld dimension file The first option is the simpler one, but I'm not sure whether it works the second option works but is complicated because you have to overwrite the dimension file for overworld and I don't know where the vanilla default file is

you also can take a look at Biomes O' Plenty, but I have no idea if they have very small biomes

the part of a dimension is json I have a mod in which I have a test dimension (I test the world generation there), you can take a look at this mod: ChunkGenerator & BiomeSource ChunkGenerator & BiomeSource Registry requires ResourceKeys Dimension Json Dimension Type Json you also will need one biome, you need to return them in BiomeSource#getNoiseBiome I hope this helps you

first post the full debug log

simpler: overwrite the method getAddEntityPacket in your entity class and return 'NetworkHooks.getEntitySpawningPacket(this)' and btw this is basic java

overwite getAddEntityPacket in your entity class and return NetworkHooks#getEntitySpawningPacket

okay, scale has nothing to do with the size of the biome the weight controls the size and the rarity of the biome

not possible without using coremods You can ask questions about coremodding on the forge discord server in the non-api-modding chanel

show how do you register the biome

this parameter indicates the biome size: p_48592_ ? 6 : 4

the mappings has changed forge now use moj mappings, you can use the forge bot on discord to convert from mcp to moj !moj -c mcp from moj to mcp !mcp -c moj from mcp to moj

ause -> PAUSE?

1.12+? What exactly do you mean by that? you should be modding with the latest version 1.16.5 or 1.17.1, 1.15.2 is at the moment also possible, but is EOL
