This is great, thank you very much. I gotta say, I'm a big fan of the attention you put into making a mess. I spent some time awhile back sorting out how to get moss growing between cobblestones and piling up debris along the edges of streets so that the locations look used. I was also struggling with how to make walls look crumbly and it looks like you've got a system that works really well. Now I just need someone to post a challenge to build a really messy battle-map to get me working again.

And the leaf scatter, top notch wdmartin!

cheers,
