so crazetex made a textured snow edit which can be found here http://forums.rpgmakerweb.com/index.php?/topic/50001-crazes-darker-skinned-npcs-and-textured-snow/ but you couldn't make textured snow for snow cliffs, but now you can with this rtp edit. here is a sample map, note in this map i didnt use craze's texture but a different snow texture thats already included in original tile sets you can repost my edit, idc if you give me credit or not, but do give credit to craze has he added in the snow texture for you this is free to use for any type of game as long as you own a license of rpg maker mv. make sure to use a region block plugin as the tile that allows you to make the cliffs is passable, and example shown here, where region 1 ID 1 is impassible. i am using Yanfly's region restrictions. its the same map so you can cross reference.
