Chisel allows conversion between any cobblestones of mod "geologica" and also between std chisel's list of cobblestone. I mean that granite cobblestone with resistance 9 (hardness 3) cant be converted in diorite cobblestone with resistance 12 (hardness 4). Blastresistance of meterials is very important for building on hardcore-tech servers and diorite is more difficult to mine material as granite. Only blocks with same hardness/resistance can be chiseled i think. Disabling cobblestone feature in Chisel2 conf isnt "real" fix of this issue.

Geologica cobblestones must be in oredict than you can use (but not convert!!!) any cobblestones for crafting. There you can use normal or more costly material to get same thing. When you convert something you create one block from other, and there you can get more costly material from normal. Thats not right.
Can you add a user configurable blacklist so the user can decide whether or not some stone types are convertible?

ModT not working with chise2! I try this:
mods.chisel.Groups.removeVariation(<PFAAGeologica:strongCobble:3>);
no changes.
And /mt chiselVariations wont give me full list)))) WTF? I waste too many time for all that bugs, thanks for that adventure.

@Drullkus Please, visit lawremi/PerFabricaAdAstra#58 for more detailed explanations about.

reopen pls.

All iteams listed under an oredict entry are to be considered 100% equal. That is literally the point of it. Chisel chooses to separate planks because it makes more sense to then end user. It also isn't possible to convert woods in Vanilla.

If you must separate the cobbles, use Mine/Mod Tweaker.

Ok, pls tell me wich code can i separate cobblestone for chisel in MT script?

Look on their wiki?

wiki ModT (http://minetweaker3.powerofbytes.com/wiki/ModTweaker:Chisel_2_Support):
mods.chisel.Groups.addVariation("hardenedclay", minecraft:stained_hardened_clay:*);
Guess i need some that:
mods.chisel.Groups.removeVariation("hardenedclay", minecraft:stained_hardened_clay:*);
But for removeVariation there on WIKI only this without groups: mods.chisel.Groups.removeVariation(chisel:hexPlating);
So, removeVariation for group is work?
