Generating Ores on already generated world

Hey guys, I was wondering if there was a way to randomly generate ores on already generated terrain. Right now I have it randomly generating, but I have no idea how to make the veins look natural.

I was hoping there would be some chunk / world method to already do this.

Thanks!

 

you mean block populator or something?

 

Sure. I have a world with just stone on it, and I want to populate it with ores.

 

Really old bump. Any ideas?

 

Use ChunkLoad event (this is called when chunks are refreshed also) and select a few random locations below a certain level. Then check if they are next to a stone block. If so, change the block to ore.

 

I ended up just writing a custom BlockPopulator and running it over the world! Thanks!

 

Oh okay cool.
