1 level causes other level to become unsaved

hi

have 2 levels
1 persistent other sub level (streaming, non persistent)
both levels have / require navmeshbounds volumes
when i switch to the persistent level, and its navigation starts to build, it causes the other level to become unsaved
i dont think it is altogether desireable
is there a way around this

thanks

im not sure but i think you can change the visibility of the sublevel on the levels tab.
but that will make the persistent level to be unsaved.
i also recall vaguely a setting that controls when a navmesh will be rebuilt. you could change it to manually perhaps, but will probably have side effects.

Make both levels “sub levels.”
The persistent one should only contain the NavMeshBoundsVolumes.
BTW. Building in a persistent map will build all the maps, but if those maps are locked, it won’t let you save them.

i need to think about what you said and how to go about it actually

must you keep all levels’ navmesh on the persistent level?
what happens when you dont

Unless they’ve done something in 5.5, which I doubt, the Nav Mesh doesn’t work.
My guess is that having multiple Nav Meshes (one per map) makes it go crazy.

lol
i have 8 or so
1 on a small map and a number on a larger map

seems ok so far

The persistent level should only contain logic.

I’m not sure what kind of game you’re thinking about, but maybe the new World Partition system would work better for you.

thanks let me have a look

how do you hide a level / streaming level in a blueprint
i currently use streaming levels to switch levels in blueprints, not level bounds if i have the name right

how would you tackle the navmesh for navigation on a large map
if i use 1 large navmesh it takes verly long to build
i need navmesh for ai pawn movement

I’ve never had issues with that. My maps aren’t that large, but I suppose it’s normal for bigger maps.

I have some transition maps and use a trigger that exposes the names of the maps, but I’ve never really thought about how it would work for open worlds. I guess I would use the new World Partition system.
This is very old; this is how it was done in the first Gears of War (2006).
