Granular control over LOD settings through mapping to distance/screen size

[deanvaessen]

As per the discussion on LOD volumes (though maybe this could also influence the global LOD settings), it might help to have more granular control over the LODing.

If I set up a LOD volume to force LOD5, but I'm a very large distance away, I will still pay for the cost. It's very black and white, whereas having more control would allow us to have detail rendered only when it's necessary.

I imagine this would be similar to the way you set up a mesh LODs in Unreal that are mapped to certain distances/screen sizes.
