Can you use coroutines like this?

    My coroutine looks like this:

     public IEnumerator heavyTask()
    Texture2D tex1=generateTexture(parameters...);
    yield return null;
    Texture2D tex2=generateTexture(parameters...);
    yield return null;

    The problem is, generateTexure is a very heavy task that can take minutes, and I need it to yield during the steps it takes.

    How do I add yields inside that generateTexture method, as if I unrolled the method into the calling coroutine and used yield there?

    You'd have to do exactly that:
    add yields inside that generateTexture method
    , in other words, turn that method itself into a coroutine, then you could yield for it in this coroutine like this:
    Code (CSharp):
    1. yield return generateTexture(parameters...);
    Of course you'd have to pass in a ref variable or something to get results out of it.
