Thats also the only way I know how to do it. I think there will be no higher hight limited in the java edition but maybe they could do it for the bedrock edition. Nevertheless your cities and builds are allways 10/10! ^_^
Yeah you’re right xD. It’s about 360 blocks height. I was only able to build half of it in game. The other half was added through rendering process. Wish there was a higher height limit in MC.
