> What is the point of importing a dataset of this complexity if you can't also work with the data inside the DCC? My understanding is, that you need to reproduce the rendering bug which crashes blender to be able to fix it. And being able to reproduce it, needs to be fast. Even if you have a smaller scene which would trigger this bug, without the optimisations it would take a lot of important time in the feedback loop. Now you have a workflow which crashes the rendering in less than 2 minutes.

    See the explanations in my other replies on this topic. It is impossible to hold a typical VFX scene in RAM to start with. Even freelancers doing sim/FX work now have at least 128GB RAM and this is often just enough for proxy work that still gets expanded at render time. I.e. consider the possibility that your worst estimate of how complex this data could be is off by 1-3 orders of magnitude. And for your example: the person who signs this off is the VFX supervisor. They don't sign off anything but final frames.

  I really don't understand your point at all. You might be right, the use case doesn't exist yet, maybe never. But this never was the point of the blog post. Making the application wait extremely long or even crash by importing _something_ is a bug in my understanding. Why shouldn't it be fixed? Why shouldn't developers improve performance and blog about it, so other devs learn from it? It's not about the Moana scene, that's just the test case, so OP has a valid benchmark with human comprehensible durations. The scene could be anything that is smaller and it will be imported faster now.
