Denseores seems to make the load time a bit longer to make images for the new ores, which for people like me, who already take a long time to load up the game, can be pretty nasty. It says you can bypass that, however, by throwing in some custom images. It seems that in the Direwolf20 1.7 pack, the vanilla ores don't have custom images. Can anybody provide me premade files for them? Even if it only shaves a minute off my loadtime, it will be worth it.
