When creating recipes for the Rock Crusher (Railcraft), it doesn't respect different recipes for different subitems. Example:

mod:GenericItem:1 -> minecraft:stick
mod:GenericItem:2 -> minecraft:cobble

Result: both items produce stick. Swapping them around in the script means both produce cobble.

(This may be a bug with the Rock Crusher, not ModTweaker, because the recipes show up correctly in NEI).

We need the script, Forge and Minetweaker log, not as embedded quote, but rather linkend via something like pastebin.
And are you aware that the Rockcrusher handler has a parameter to ignore Metadata?

Yes, the behaviour is identical irrelevant of that setting.

Here is the .zs file in question: http://sprunge.us/HKjV ; the problem lines are the ones which are currently commented out.

Will generate some clean logs on a reduced install.

matchDamage

Ah, I had stupidly set matchNBT to true, not matchDamage. Works as intended now, many thanks!

@Voidi why is Meta and NBT a boolean btw? :P Isn't this handled in IIngredient or is that not compatible with RC fully?

@Yulife Because the ZenScript method Reflect the Railcraft-Api, where there are these two additional parameter.
But i will simplyfie this like I made it for the Cokeoven.

You state that it doesn't work irrelevant of that setting but the script you have the matchDamage set to false in that script. So it is ignoring the meta data value. Would be best to provide the script that is expected to work. So use:
mods.railcraft.RockCrusher.addRecipe(<Railcraft:ore:7>, true, false, [<RotaryCraft:rotarycraft_item_extracts:25>, <minecraft:cobblestone>, <minecraft:gravel>], [0.2, 0.1, 1]); We use this extensively in our pack and it works as expected.
