Skydome wont show up, and Lighting problems.

Midyin

I have it set in my render settings, but out my windows is just the grey and white checker pattern.. 

considering it takes 5 hours for my renders to even look half decent, i dont appreciate having my time wasted on a render i cant save/keep... 

 

i so miss the 3Dlight days... :(

Hello

Are you trying to use a 3Dlight skydome using Iray to render with? If this is the case then the skydome will not show up. Daz studio also has a 3Dlight render option as well as Iray so that 3Dlight content can also be used. Hope this helps.

When you say you set it in your render settings - do you mean that you set Draw Dome "On"?

No, i have the Draw Dome setting on.

Which version of Daz Studio are you running? Maybe you could post a screenshot of the Render Options "Environment" tab too?

Having Draw Dome ON doesn't mean anything if you don't have an HDRI map (with an image) loaded.

Draw Dome on gives a Sun and Sky background either with Dome Only or Dome and Scene, with Scene Only you get no light at all. The only way to get the checkered  background is with Draw Dome set to off.

This all just comes back to me HATEING IRay.. its such an overly complicated mess... 

even now, my scenes are too dark despite me cranking my Lumen on EVERY LIGHT up to 50k, but still no change from when they were set to 5000...

What kind of light? Have you tried adjusting the Tone mapping in Render Settings, rather than turning the lights up?

What kind of scene are you working on? If there's no change, the lights might not be affecting the scene properly. Did you turn off the default Environment light? If your scene is outdoors, that might be skewing the lights you put into the scene.

There's also a difference between light objects and mesh lights, they need different settings; depending on your scene, 50k lumens might be nowhere near high enough.

I'm not using any kind of scene lights its all just spotlights.

 

the first image has every light set to 500000 Lumen.

the second image is 50000 Lumen. 

and the third 5000 Lumen.

So i have 11 spotlights lighting my sceen because the environment i am using(https://www.daz3d.com/studio-type-room) didnt come with lighting of its own(or its hidden away someplace that i cant find), so i did some experimenting and found that some of my lights werent showing up for whatever reason, so i set thier render priority to above average. 

i clicked render, and my PC Blue Screaned... Seriously, [drat] IRay..

Seems to be an issue with this product.  There's another thread about the same issue here:

https://www.daz3d.com/forums/discussion/251696/

So the thing with this set is that it has lights built in.  You can see them lighting up the walls in your screenshots.   All the lights are emissives, though.  You can adjust them by increasing luminosity in the surfaces tab when you select the roof.

Another issue is that not all of the set is in Iray.  Some of the materials are 3DL.  Unless you want to fix the shaders yourself, I would request a refund.  This is kind of old from the really early days of Iray and one of this vendor's early efforts.  They have made much better rooms since this one.

@Midyin "This all just comes back to me HATEING IRay.. its such an overly complicated mess."

Iray isn't complicated. It simulates real light effects. Good photogrphic lighting is complicated if you don't understand. There are any number of photographic lightin tutorials available.

50K lumens may not be enough, but 500K is too much. If your lights are set to 500K, they are being blocked by some object. 

You can also see by a casual scan of the gallery and forums that Iray works for a lot of people. Attached with Painters Lights (classic 3 light setup).

Yet nothing was blocking my lights, so......

Easy way to double-check. Drop down the menu for Cameras/Views at the top of the Viewport, and select one of your spotlights from the bottom of the list. This lets you look through the light as if it's a camera. Note that wide-angled lights will look very distorted when you do this, and your scene might be tilted or actually upside down (ignore it if this happens, it doesn't matter because you won't be using this view as a camera for rendering). Any view that's completely black will be a light that's blocked by something or partially inside an object.

Just wanted to come back in here and give a big shoutout to Sevrin. Exposure was 100% the issue. This is the image with the Exposure tured down from 13 to 10.

 

Thank you all for your help. :)
