Quick question. What is the internal mod name for red rock? I'm using xreliquary and I want to add red rock to the "mundane materials" list for the destruction catalyst. It deals with names however instead of numbers (Using the latest version for MC 1.7.10) I tried "extrabiomesxl:redrock", "extrabiomesxl:red_rock", "extrabiomes:redrock", and "extrabiomes:red_rock" with no luck. And I have no idea how to pull the block's name from inside Minecraft itself (Sorry if that's noobish of me ^^;)
If you're using NEI (usually a safe assumption), open your inventory and click the Options button in the lower left-hand corner. From there Tools > Data Dumps. From there, you can get the IDs for items, blocks, potions, enchantments, and biomes. It'll drop them in [your minecraft folder]/dumps as .csvs, which can generally be read by any spreadsheet program.
