Thanks for the info!
I have considered that but I believe that would make the ores generate floating in or on the surface of the pools, which isn't what I was planning.
It could, however, work if I changed the texture to something that doesn't look like stone, and I add a piece of lore saying it's an ore that forms floating in lava pools, when the lava slowly cools down.
This is brilliant, but just in case I need this for something else, don't you know a way to hook into the generation of specific features?
In any case, I'll start working into this and I'll add you to the credits!! Thanks!!!!
