I added a file to reference in the BiomeTweaker.cfg file called testing,cfg
I updated that code to read- "include":[testing.cfg]

The testing.cfg file has example code pasted into it. The code to turn every biome into mostly desert. I can post it if necessary.

I want to use the biomeTweaker features but I can not even make the example work for me. When I create a new world (in any world type, Default or BOP) the world spawns in normally with no changes.

I am running Minecraft Launcher 1.6.13 and release version 1.7.10,with Mods BiomesTweaker-1.7.10-1.1 and BiomesOPlenty-1.7.10-2.1.0.1387-universal, through forge-1.7.10-10.13.2.1291-installer

Any suggestions are appreciated!

Your config should read

"include":["testing.cfg"]

Please add the quotes and get back to me.

I was unable to reproduce this issue on my side with the setup you have described. Both normal and BOP world types generated the appropriate terrain (there is a BOP Oasis to my left):

Something else is wrong. I'm going to guess your config is formatted incorrectly somewhere, or it's simply not being read.

Great catch! However, it seemed to make no change in the world generation...

This is the entire testing.cfg file

#Specify ids
desert = forBiomes(2)
hills = forBiomes(17)
river = forBiomes(7)

#Add desert to all types so other stuff doesn't appear as often
desert.addToGeneration("WARM", 2000)
desert.addToGeneration("COOL", 2000)
desert.addToGeneration("DESERT", 2000)
desert.addToGeneration("ICY", 2000)

#control spawns
desert.removeAllSpawns("CREATURE")
desert.addSpawn("net.minecraft.entity.passive.EntityPig", "CREATURE", 60, 1, 3)
desert.addSpawn("net.minecraft.entity.passive.EntityChicken", "CREATURE", 100, 2, 2)

#repeat for desertHills, not as often tho
hills.addToGeneration("WARM", 200)
hills.addToGeneration("COOL", 200)
hills.addToGeneration("DESERT", 200)
hills.addToGeneration("ICY", 200)

hills.removeAllSpawns("CREATURE")
hills.addSpawn("net.minecraft.entity.passive.EntityHorse", "CREATURE", 10, 1, 1)

#river spawns
river.removeAllSpawns("CREATURE")
river.addSpawn("net.minecraft.entity.passive.EntityCow", "CREATURE", 60, 1, 2)
river.addSpawn("net.minecraft.entity.passive.EntitySheep", "CREATURE", 40, 2, 2)

Tweaker.setStage("PRE_INIT")
desert.set("reedsPerChunk", 20)
desert.set("clayPerChunk", 10)
hills.set("clayPerChunk", 10)
Tweaker.setStage("FINISHED_LOAD")

#Remove other biomes
all = forAllBiomes()
all.set("genWeight", 11)
all.set("isSpawnBiome", false)

#remove all water (keeps lakes tho)
all.registerGenBlockRep("minecraft:water", "minecraft:air")

#final weighting - hills about 1/10 the time
desert.set("isSpawnBiome", true)
desert.set("genWeight", 50000)
hills.set("isSpawnBiome", true)
hills.set("genWeight", 5000)

I'm going to require a full log then (on pastebin or similar). The file I need should be called "fml-client-latest" or something similar.

Thanks so much for your responses! The test is supposed to add desert (sand) to all biomes, but I am not seeing that. The world generates as if BiomeTweaker is not installed. I checked and it IS showing up as an installed mod.
Here is a link to that file - https://www.dropbox.com/s/mpuayvtu7kdnrqu/fml-client-latest.log?dl=0

I also added Natura mod but I don't think it made a difference

Umm, I just noticed what file you said you were running... Where the hell did you get it? The mod ID is "Biomes Tweaker" and the version number is missing the build... It's not even signed! I always sign BiomeTweaker jars I release.

You should only be downloading BiomeTweaker from here:

http://minecraft.curseforge.com/mc-mods/228895-biometweaker

Are you using this, and thinking it's BiomeTweaker...?

http://minecraft.curseforge.com/mc-mods/224502-biomes-tweaker

I don't even know.... crying face

Pretty sure I got it from the first link.

The jar you are using. It's not from me. It's not even BiomeTweaker. It's a completely different mod.

Download the latest version from here:

http://minecraft.curseforge.com/mc-mods/228895-biometweaker/files

Use that. Move your config to the correct folder. ???. Profit.

So listen up. In my mods folder I have a BiomeTweaker folder with configs inside that. Also in my mods folder I have a BiomesTweaker config file - WITH AN S. I deleted that file because its not from you. Then I started up minecraft and it came back, So I deleted every biometweaker mod from my mods folder and reopened minecraft AND IT CAME BACK!

Here is the file -
https://www.dropbox.com/s/5i9ea69qg4nq9ur/BiomesTweaker.cfg?dl=0

If your mods folder is truly empty, it won't come back. Then, download this and put it there instead of "BiomesTweaker-1.7.10-1.1".
