Minecraft Forums

I just started playing minecraft a few months back, and have pretty much no experience with mods so please bear with me. I am simply just looking to find a witch hut and either slab the entire world or make it all air blocks so I don't have to put in the enormous amount of effort to do this just for testing spawn rates. My understanding is that worldedit was the best way to go about this, but it currently doesn't work too well for 1.8.1. I see plenty of videos on youtube of people doing it in 1.8.1, but not sure what they are using. Any help would be appreciated! Thanks in advanced.
