I'm using this mod in 1.10.2 together with Realistic Terrain Generation and Biomes O Plenty. Latest versions of all.

I've been trying to put together a new world, so I've been flying around testing quite extensively, but I keep seeing just the same 10 or so biomes over and over - some are vanilla Minecraft, and some are BoP. I've attached the file i'm using to define the weights etc. Am I doing something wrong in the file, or is there some kind of issue with reading the weighting ?

RTG.zip

I'm not entirely sure, but it seems like BOP for 1.10 is ignoring most of BT's generation tweaks. I'll look into it.

I think it's just gotten better with the latest BoP update - was just testing it:
"BoP Build 1.10.2-5.0.0.2075: Adubbz: Fixed a problem with biome configs not working"

Still doesn't feel 100% right, but is definitely better.

has there been any discoveries?

I have been trying to get heavier weights for the past 3 days with BOP biomes on my worlds. No luck.

If the BOP configs aren't working for setting weights of BOP biomes, I can't really help you right now unfortunately. Don't have time to look into this right now.

Going to close this with the latest addittions. Commands have been added to allow tweaking in the BOP world type.
