Okay so first off I know what I'am trying to do is WRONG you don't have to remind me.
One of my mods I'am trying to port from 1.6.4 I had it get the vanilla ores from the block list and set them to null "Block.blocksList[block.oreIron.blockID] = null;" like that, then I re added my own version of the ore with a custom texture etc.. and added it to the forge oreDict. Everything worked out fine no crashes, all the ores I changed worked with every mod etc..
I can't seem to figure out how to do the same in [1.7.2].
Since ID's are "gone" now I realize that other mods might not like how I did that before, now. So if I can somehow change the vanilla ore's texture without having to give out a resource pack with my mod, that could work for now if its possable.
But I still wouldn't mind figuring out how to do what I did before, now.
P.S. Sorry if I explained this weird.
