    LightWave Physical Sun / Sky settings and other render engines

    LW 2018 / 2019 have the new physical sun / sky model based on Hosek-Wilkie.

    As I mentioned in another thread I'm not convinced by its quality and easy of use but that's maybe because I'm not familiar with it.

    Based on Prometheus request to provide screenshots of sun / sky settings in other render engines I created this thread.

    For example I was not able to create soft shadows with the LW Sun. Also in 2019.1 it's not possible to modify the horizon blur. Note that other engines also provide additional Sun / Sky models like CIE or Preetham. If it's of interest I can render those too.

    It would be great to see some good LW sun / sky settings and rendered results.

    In this scene I added a couple of parametric objects and default RedShift Sun / Sky - Render time a bit more than a minute. I would probably increase the sun intensity and lighten the shadows a bit in those.

    Please don't judge textures, I just used default rock object and material without any bump/normal/displacement/roughness and no post processing.
