Hello,
World composition has always been “complicated” to use, plus a lot of issues can happen (
oops, some information was lost, lets restart !) and it’s buggy (to say the least) with the great but sadly useless Water plugin. 
Will we be able to, at least, convert a project using it for UE5 or should we start creating maps with a big (not tiled) landscape ? Does anyone have an answer ?
Thanks
