Topic category: Troubleshooting, bugs, and solutions
Exactly what it sounds like. MCreator cannot tell one type of wool from another. The same problem exists with logs, stone, and hardened clay, to name just the ones I have personally tested.
The fix is simple enough: The application, for display purposes, can already tell one from another in the recipe creator, at least insofar as selecting goes. (When it comes to actually creating the recipes, it forgets that andesite is NOT regular stone, nor is it diorite, nor is it granite.) The only change that has to be made is to fix this problem is to actually implement that code everywhere else it check for item/blockIDs.
In the mean time, however, any crafting recipe that needs to differentiate between colored wool types, any custom procedure that is supposed to do different things based on the type of log you put in, et cetera, CANNOT FUNCTION.

Fair warning: having read through that thread, I feel I should inform you that it isn't limited to procedures. EVERY MCreator action that handles Metadata is broken in this way, most notable recipes.
In recipes, metadata indeed works, except for mob spawn eggs which have a different implementation. Which version do you use?
At the very least, in 1.8.1, I was unable to create recipes that have different outputs based on the type of wool used as input. I haven't tried in 1.8.2.
There are some stange bugs with recipes. We will move to JSON recipes in MCreator 1.8.3 and this should fix these bugs.
