Sun and Sky Only...Anyway around this?

Am I correct that photometric lights can not be used when in sun and sky mode only in Iray? I find myself loving the sun and sky, but still needing to add key, fill, and rim lights. Am I missing something? What can I do? Daz Studio 4.10

    I'm a ways away from my console to test it, but I'm pretty sure if you change it from Sun and Sky to Dome and Scene, then click the image map on Environment Map and set it to none, you should get the sun and sky settings back while allowing scene lighting to work.

    Yes.

    Thank you, after playing a round little I accidentally stumbled onto this as well. This actually explains a lot. My default always has the DTHRI_ruins in the map channel, now I know to go empty it out.

    I think I did try that only this week but the photometric lights still didn't work but I don't remember so I'll try it again.

     

    ----- so i tried it & that was the problem why the photometric lights weren't working in my scene. Could of swore I tried that the other day too but I must of got confused and what i was seeing in the render. My 'night sky' at 1 AM on *Summer Solstice though is still disturbingly too yellow-grey like a dirty Manhattan sky polluted with light but I  don't know how to change that outside using a background image of a night sky.

    You could play with the Iray Sun-Sky "SS UTC Offset (hrs)" setting until you get the effect you want.

    Or, if its important to use the correct actual "Real-World" Date + Time + UTC Offset, then try changing your computer's Timezone to 0 (UTC=0) before launching DAZ Studio.

    I did not know this. 'Bout tore my hair out a few months ago looking for a solution. Very good information, thanks.

    The Sun can be set to Camera mode, so you can position it wherever you want without the complexity of the time settings. Use iray preview Interactive to easily learn the amazing range of the environment controls.

    Oh, I did. I used the coordinates of a point on Loch Ness and set to UTC to be 0 like it should be. Then I set the time to 1 AM at summer solstice (Jun 21 2018). Maybe Loch Ness is to close to the Artic Circle for proper darkness at 1 AM on summer solstice.

    It is probably getting light at 1am on June 1st. You will get a dark sky if you set it to December 21st. I have sat out all night in July on the Moray Firth and the sky never got completely dark unless it was cloudy. You can also change the SS Night Colour to black.

    This image was taken from my tent door in May around 2am although slightly farther North than Inverness.

    Thanks, I was in Iceland in June and it stayed sort of dusk all evening and morning but I've never been to Scotland except in spring.

    ..what happened to the custom setting (sun chain) that used to be in the Render Presets folder? I found having to mess with the day, month, time, and location coordinates to be more of a bother than needed.

    It is still there. Quite useful.

    ..ah there it is.  Was distracted by the 3DU folder in there that had environment lighting for Amber.

    Indeed so much easier than dealing with all those calculations. Why they even bothered with that I don't know as we have very few "real life" location sets and HDRs have their own "sun".

    If I use one of my own photographs as a background I use the Exif data to set up the Environment and camera so that the light, and therefore the shadows, roughly match the ones in the picture.
