I ve actually got an issue with my level streaming system, It’s an small open world with actually 3 areas built and an inventory system.
When I m in for example area 1 and pick up an object, the whole world disappear even if I place this interactable in the persistent level or the area1 level,
My pickUp system doesn’t have trigger, it’s just a line trace system to actor.
This is the first time I use level streaming, I’ve simply use trigger boxes around the level I want to stream and call it from the persistent level Blueprint.
My interactrable have a BP interface, I call it from the Main character BP, then Cast to my main character and then tell what the interactable should do or where in should go.
I can’t figure out what i ve done wrong but it does it with every interactable.
Going to assume you are not changing the visibility of the world or the camera and you’re not destroying any of them as well. Perhaps memory or graphic issues are to blame? Without any real sense of your blueprints and/or a video showcasing the problem, it would be rather hard to determine what could possibly cause the whole world to vanish while you are playing with an object. Unless something in that part of the object’s blueprint is doing something to the effect of the first line of this post.
I don’t think it s a memory problem, I’ve tried with a map of 4 props, it’s similar.
It happens since I m using level streaming, it’s the first time I use it tho and I ve proceed like shown in the UE Doc: Trigger sublevels from the mainlevel BP, nothing more, I m using sublevels inside sublevels too like i ve got an hospital interior level inside the “area1” sublevel.
And I ve got a new problem, before, I was able to move after picking up an object and if I went out the trigger box and back, the level was called again but now, without changing anything, It’s like it disable all inputs right after I pickup the object…
Here’s a video of the problem and pics of the line trace system/Inventory (can’t be more classic) and levelBP, my subs levels BPs are empty as well as my master interactable BP.
