Sky Model

Any plans for an updated Physical Sky model?

@Stephen.Blair Any comment?

What kind of updates are you looking for?

Well, Vray uses the PRG-Clear sky model and Redshift will be implementing their version of PRG-Clear Sky in the next update. It just offers better look especially at sunrise and sunset.

Here's a link to the Redshift forum post - Saul from Maxon shows a sunset comparison.

The PRG model seems to have a much larger and more intense sun at the lower angles which in turn gives a nice look on interiors. I've tried but I can't replicate this at all in Arnold.

@Stephen.Blair I spaced on that the forum needs a sign in, sorry about that.

I've attached the comparisons by Saul.

Would be great to have something like this in Arnold.

@Stephen.Blair any comment here on the sky model Steve?

Ehy! 🙂 if you're interested in sky models, join Arnold discord server (max-rombotools channel) to see our latest sky dev, upcoming with v1.5, we're implementing multiple models (PRG is already there) as each has its own strenghts.

@maxtarpini this is great news.

+1 for some upgrades to the native Arnold Physical Sky Shader

Just to link the V-Ray docs, the option for cloud shadows is amazing:
https://docs.chaos.com/display/VRAYHOUDINI/V-Ray+Sun+Light

(while this wouldn't likely be used visually being replaced by a matte painting- saves having to always create light blockers / gobo)

In combination with this, what would also be incredible:

1) Being able to see the resulting sky shader in the viewport.

2) Viewport controls to move the sun position while the sun haze still corresponds correctly etc.

All the best.
