following this tutorial: https://www.youtube.com/watch?v=QrGhnCEO5Wk&t=8s
i can get a kind of undefined volume fog - but no godrays.
Also the values for distance in the volumetric material I played with to get any kind of volume fog are completely differnt to the tutorial.
I started to day with the 1.5.1 hotfix download a trial period.
I will attach my scene and a reference render.
Would be great if someone could point me to a solution.
Not a useful post but personally interested in learning more about this, I also had problems getting ‘god rays’ in my scenes. I found having the sun within shot makes a massive difference, not sure if that helps you at all!
Absorption distance - this can be sometimes confusing, so some experimenting was required
After lowering absorption distance the whole background became black - it was fixed by changing environment distance in Render Setup > Performance > Development/Experimental stuff.
The godrays are not clearly visible in this scene, but they do appear if you move camera/sun.
The devel/debug parameters are hidden by default - to expose them, go to System tab, click the System Settings button to open the dialog for system-wide settings (new in 1.5), and the checkbox for devel/debug is there. Check that, close the dialog, and head to the Performance tab and you will see those settings.
