HM, static mesh through BP’s has complex as simple, so now simulate physics not is not greyed out, but in play I get , Trying to simulate physics on ‘’/Game/Map/Esse_tall/UEDPIE_0_Esse_tall_X0_Y4.Esse_tall_X0_Y4:PersistentLevel.Rope_C_1.cable end’’ but it has ComplexAsSimple collision. , is that a bug or how can I fix if not ?

I found forum post, but it went nowhere

It is not a bug. Open the static mesh editor and set collision complexity to “use simple as complex” for physics simulated objects
Doesn’t work, I set it what you noted, but now Physics > Simulate Physics is again greyed out. Maybe the tutorial was too old, but I have rope working at least, just that error. SO close.
Does the mesh have a simple collision setup? Try to add one:
OK ty, that did it ;_) Now I just need to get it to stop flying away on play. Always something for us game dev’s to do ;))))
its collision is probably overlapping with something else the moment you spawn it, that is often the reason something launches into space 
Thx , solved that ty 
I think constraint was a bit off. Now onto rope climbing, if it matters this is what I’ve been watching, getting ideas.
