Real Sun position, strenght, color - based on location
Hi awesome community. I think that it would be nice to have real sun setting in Blender.
It could be implemented as check box for "real sun" (or similar name) in the sun lamp properties. Then after expanding this panel there should be location (based on lattitude/longitude), date in the year, time odf day and north offset. Also some presets for this purpose would be great.
This setting could then overwrite Lamp position as well as its color, strenght based on location/date/time of day and could be animated for quick sun studies.
Would be very usefull for Archviz workflow.
Regards Martin

this addons already exist. blenderartists.org/t/very-realistic-sun-studies-for-architects/532395/143 work fine on today blender 2.80 beta daily build
I think I've seen that as an addon a few months ago... Can't remember which one though... I googled "blender addon real sun" and found that addon .
this sounds like an add on or something else
* @momotron2000 * Yeah, this sounds like something that could be done via an add-on. Probably not on the sun lamp, but on an HDRI though
Ohh !! fantastic ! thank you really
Real sun: (even with analema) arts.brighton.ac.uk/projects/vi-suite Not available for 2.8 yet
Thank You guys for info. I will try proposed addon. Greetings
* @MDa * If it works maybe consider changing this request from open to done or so
I think this sounds like something that should be an add-on. With Blenders current features it would be quite easy to setup up a "real sun" with python and a bit of math to manipulate the existing sun light and even add some gradient and noise to the background using nodes for some sky effect.
in 2.79 there is also "geographical sun", without fancy ui, but also crash free
To compute this it's needed a very undefined thing: where is the north. Blender do not have cardinal directions by default, so a realistic sun should adopt one axis to point north. However, choose x or y to point north is just a convention, personal choice.
