Hi, my name is Michael,
i finished my first project a couple of days ago and i ran into a little problem that i cant get my head around it. Maybe some of you can help me out and point me to a better solution for my problem.
i have build a scene where you can switch the roofing of the terrace at runtime. i did this by using levelstream. Each Roofing is saved in a separate Level.
on press of a button you can load up the next roofing
the blueprint behind this looks like this
So basicly by the press of a button the blueprint load “Roofing A” and unload “Roofing B” and “Roofing C”
this works for 3 Objects, but when i have to change 50 Objects i am a little bit afraid that i am loosing my mind doing it that way…
so is there a smarter way of doing this?
i am a totaly beginner in unreal, so please dont laugh to much about my solution at the moment 
Thank you very much for your help and kind regards from Vienna Austria
Michael
