[Help][4.26] Water (Plugin) with tiled landscape?

Are you sure there were no other parameters? my map was imoprted with edit layers on, and I can’t get it to work.

I also tried to use it on the Boy and his kite example project, although I’m not sure if the map was imported with edit layers on, or enabled after (or even if I enabled it personally at some ppoint).

Can anyone else check it?
