I'm having difficulty finding any relevant material on this - generating the cave system as such is easy, as is the terrain. However, I'm having trouble coming up with a seamless way of merging the two. Not sure if there's anything else to my question as it's pretty straightforward in nature - any links/book suggestions/just suggestions/ideas to any relevant stuff and all such would be greatly appreciated!

Cheers - I'll have a look at that! Funny how there's absolutely nothing relevant readily available on the web - it's not like this should be an overly niche subject..
