Other than the nuclear option of replacing OSG with hand-written rendering I don't have any ideas for that so I'm exploring something what could be done. Billboards aren't a silver bullet but nothing is, and at least this could allow replacer artists to do the work of tuning some distant features to look right instead of hoping for an algorithm to do it reliably. But even so, it's still not a solution for the vanilla game so pushing it beyond 1.0 is pretty much a given, if it ever even is supported.
Everything about development and the OpenMW source code.
Never attribute to bad code, that which can be adequately explained with clever hacks
We've got a pretty good design for a system that should 'just work'. It doesn't require abandoning OSG or even using it in ways it wasn't designed to be used. It's just that no one's implemented it yet.
