Not for the free pack. Sorry. The waterfall has a top and middle portion, each with left right and center. For the cliff section, there's a left, right, and center for the waterfall top as well.. Everything should be named appropriately.
it seems that my problem is because the waterfall parts (water) are 0.2 unit to hight
thank you for sharing the value :)
i have the same issue. (nothing "game"-breaking ;) )
