stuck with world composition

hi all,

i am trying out some of my wm landscapes in unreal and it works great.
single maps are easy and for the tiled maps i have followed the wiki worfklow of enabling the world composition-

and that is where i got stuck.
imported a 16 tile landscape and tweaked the scene some. i would like to proceed with the scene but:

  • i cannot move any of the tiles.
  • imported a single landscape actor into the scene and now it too cannot be moved.

apparently the tiles are locked. some refer to editing them in world browser but i cannot find the feature in 4.10 or 9.

also:
each time the project is opened all of the levels are unloaded which i have to do manually. can i preload the levels on start? is it an .ini thing?

attached are some screencaps:
basically i´d like to start expanding on the horizont with a couple of more instanced landscape actors, placed so they obscure the obvious cutoff.

presumably my issue has something to do with the way levels are handled, but i actually dont need them as such. if there is a workaround where i can import tiled maps into a single level, that would probably be best.

btw, i had to downscale the screencaps in order to upload them.
anyone knows what the upper res limit/size is?

cheers frank,

im a dolt, was looking all over the place and missed the icon.
the world composition opens, but icant seem to zoom in or out. i will figure it out though.

so if i am to bring another landscape actor in, should i do it via level or just by regular means?
if i just import a single map landscape into the scene, i cannot move that either.

what i am wondering how these levels relate to the active scene i am in. done some reading, its still a bit convoluted.

best,

frank you are a prince. this helps alot.

i am trying your tips out and will probably have more questions.
working on a wacom here without a mouse, so i have to figure out how to zoom around:/

thank you!
