Hello, I am having an issue with showing a class with an array in inspector. This class A is used as a property in a class B, the class B is used in an array of a class C, the class C is used in an array of a Monobehaviour.
The hierarchy is like this and this does not work, it crashes with different errors (see below):
- MonoBehaviour
- List
- List
- public A; (A contains an array of audio sources)
But this instead works completely fine:
- MonoBehaviour
- List
- public A; (A contains an array of audio sources)
Thank you so much for your help!
The stacktrace of the crashes for the first scenario:
