Hi. I have a tiled map I built in World Machine. I create a new project in UE, enable World Composition and rebasing (tried it without rebasing as well), go to “Import tiled build”, select my tiles, **add some landscape material (this is key)**, and hit import. In 4.25, the Engine starts importing my tiles, and sometime later, everything’s imported and works as expected. When I do it in 4.26, the editor just hangs. It just imports the first tile (I can see it in the tiles folder in the engine), and pretty much stops. I waited for an hour just to be sure, and yeah it just hangs there. It only happens in 4.26, and only if I do my import with a landscape. I tried different landscape materials, and the same result. If I just import the heightmap without selecting a landscape material, it works as expected. Anybody experiences this? ---

Same here. I tried importing with splatmaps and landscape material - doesn’t work. Importing just tiled heightmap works, but without splatmaps it’s pointless. Any solution to this? ---

Actually it appears to be working after creating very basic landscape material with 4 layers and just base color constant applied to it. At least it appears to successfully import my 37\*37 tiled world composition with 4 splatmaps. - I confirmed it’s working after loading a bunch of random tiles on the map. There’s a bunch of bugs that would take to long to describe in a comment, but after a bunch of engine restarts it works! ---

But I presume it doesn’t really “fix” it, right? Just for that small material? ---

I’m also getting hit with this. Specifically it seems to struggle with reading the weightmaps. If you add a texture with no weightmaps its fine. ---

Same issue here. Any fixes?
