Making Caveins (debri)

[Elven]

No. Sadly cavein is static item meaning that you cannot make it invisible and then visible. I had same problem in my own Ray of Hope custom story.

There are 2 solutions what you can do.
A) Use entities rocks, maybe scale them and have shit load of time and not guaranteed work.
B) (what I used) Go into custom model editor, edit the cavein into entity and then you can use as Selyp says, first set it invisible and then via that upper function set it visible. Worked perfectly for me .
