4 things should do:
1. The physical sky looks outdated now, it should have a sexy and realistic sun, moon and atmosphere, even programmable volumetric clouds that can be adjusted.
2. Save time first, Arnold needs to build a huge material library, users can easily manage and add any materials they want, no more preset pls.
3.Vray's uv randomizer node is useful, add it.
4.They didn't even have angle & radius measurement tool, this must be a joke.
