I created some landscapes and when they are done they are material less and complete invisible. If I push play I can see the landscape and what I painted. I made multiple landscapes all remain invisible no default grey look.
EDIT : when I load up the world partion map it says warning Actor Landscape has empty bounds. I looked up code where that is pushed. But I got no clue.
I think that you have to load World Partition cells, the only way I could see to do this however is right click in World Outliner on a LandscapeStreamingProxy and select “Load Cell” or whatever the menu item is. Sorry not actually sure of the menu wording now but only had 3 or 4 choices … so cant really miss it.
I went back to 4.26 but then I got stubborn , I grabbed the ue5-early-access branch , then I compiled ue5-early-access-1. So in the tag release the landscape is grey and visible. Its bug with current branch. As well tiled landscape seems to be bugged.
For whatever reason hitting G (hiding the grid) worked for me.
Thanks for this comment! It saved me from a lot of frustration. This is still a bug in October.
thanks a lot!
This is still happening for me in UE5.0 release. That is so weird. I have to press G to edit the landscape. Then back to grid mode. Makes no sense. Has anyone found an alternate solution to this. Also, I can see it when doing Lumen Overview.
I also got that problem and I got a solution! Just go to Show tab in viewport and click “Landscape” or click Alt+L
. Thats all!
@Kokoszek2 Worked for me thx!
You don’t know how dumb i feel right now… I absolutely lost my mind for 2 Days now, course i cant see Landscpes in the engine. I event dumped my Maps re try do get it running gain… wow
