Render3DItem.java

// Credit goes to iChun and Zorn_Taov (iChun because Zorn got it from him)
// IMPORTANT, make sure when you register your item, it has the .setFull3D() on it, so:
// myItem = new Item3DItem(myItemID).setUnlocalizedName("My3DItem").setFull3D()
//
// in your CLIENT PROXY, you need the line 
// MinecraftForgeClient.registerItemRenderer(myItem.itemID, new Render3DItem());
