The chasmledge crosser was for the "old forest"... (i dont think i still got the files but i know how to do it and tell you) and the caves. I´m sorry for the delay but i´m such a lazy robot when something doesnt fit in my "actual" mindset....
So what i did with the crosser was (if i recall) i just did "features" for the chasm/cliff sections. So you had to add the correct features to the chasm to create the trail and thats it. This way i didnt have to mess with the "rules" because i hate them and voila within 5 minutes you have a nice new terrain calles chasm ledge without messing around with "how does that crosser works between these 2 terrains and alligns correctly....".
Anyway, i will prepare that cave tomorow. TOday is football and germany is winning '>
