Sun and Sky sun intensity

[brainspoon]

Hi,

Could you please point me to an equation to how you actually calculate the sun intensity for the Sun and Sky system? I am thinking about adjusting my hdri toward this values to make it easier to switch between both.

Right now when doing a rendering of the default sky sun I can see that you are generating a value of [3124712,3105122,26396..] (can't read the last values from the color inspector).
But those values are way off the lux that I found for the sun when searching through the internet. Those most times where around 100k. Maybe you are using a different unit?

Any pointer would be appreciated.

Thanks
Andreas

You can probably find equations in the papers we've used to implement the sun/sky system.
The list of references could be found here: http://docs.chaosgroup.com/display/V...nks&References

I already looked through some of them. Right now I just did find information about the sky. Not the actual sun.
