Not able to reproduce the error now. I am doing the length check.
My code links and unlinks objects from the scene on a frame by frame basis. Perhaps there is some problem with an object after it has become unlinked, then relinked to a scene.
Do you remember what the error was? I’m not familiar with the code, so without that I can’t really help, sorry.
The other thing is if you get the error again/recall it then please post your code. Without being able to trace the execution flow it’ll be impossible to tell what the issue is for anyone that hasn’t seen it before.
