how to change the scale of elements in landscape auto material tool

how can I change the scale of those elements such as grass and rocks, cos I find those elements are way bigger than my character which is the normal size~thanx

Same problem hereā€¦ any solution?

yes, they are much too big and the only way would be to export each and re-import smaller. thats not really practically and each user would have to do that. so best solution would be to complain to the creator and bring it up in the marketsplace discussion to the pack.
