Actually just by downloading the map you have it. You dont even have to install it, all you have to do is copy the map into your saves folder and when loading the map in game custom textures will automatically be used. Whats great about it is that it only uses them when playing the map so youre back to vanilla on your other saves :)

Well if it makes you feel better, this wasnt a 10 mins build, i think i spent about 2 hours total to get her perfect <3 The custom textures do alot of the job too ;)
