[SOLVED] Loss of emissivity and scene light intensities
MeatRoots
Posts: 22
Since the 9th for Vol 1 and the 15th for Vol 2, I cannot for the life of me get the lights to function. Nothing will emit from ANY of the set lights. Only things working are the enviroments. I even followed the directions on the PDF file. Something's up and I cannot figure this out.
I also tested my usual emitted primitives, and they worked fine. Clothing, hair, eyes... all emit light. But the lights supplied in these two sets... nada.
Is there something I should be checking on with the item itself? I'm pulling my hair out here. For days I have rebooted, rechecked, defaulted, sank into catatonia... nothing from the sets will emit light.
Any help would be HUGELY appreciated.
DS 4.9 (latest)

I have both and just tested them. They seem to work fine for me. Some of the lights rigs have to be selected before some of the settings will be applied to them. Also make sure that in your Render Settings >> Environment that it's set to "Dome and Scene" and not just "Scene".
Render Settings.... check.
Now, I know I have selected the rigs correctly (at first, no... after a few attempts, I finally did) because when I look at the settings... for example, when I apply a number of LED on a ring... the thumbnails do show a ring with the LED dots in the materials.
*edit*
Wanted to add... thank you, @divamakeup, for responding.
You're welcome. :)
Are the lights still not working?
No, still not. I changed characters or used props, but nothing. Settings for surfaces/etc/etc appear like they SHOULD be viewable.
That is REALLY strange. :(
So other lights are emitting light? If so that sounds really weird and sounds like it's probably an issue with the product - perhaps not downloaded correctly or something? Perhaps uninstall the product and reinstall it?
Why are your clothes, hair, and eyes emitting light?
From testing. I allowed them to emit light to see if they would... to isolate issues. So, now, it's just the rigs for both volumes.
Oh I see. Yeah, it does sound like an issue with the products then. That's very strange. I'd try to uninstall and reinstall the product and see if that fixes the issue.
Ok. So, I uninstalled all Ultra Genesis Studio products.
After reboot, I only installed Volume 1 (Box Lights). THIS TIME, from within DS instead of DIM.
Still... nothing. Absolutely no signs of light being emitted.I even moved the emitter down the tube, up'd the intensity, moved it closer to the primitive cube... nothing.
***I test something else before I hit "post comment" and come across this***
Uhhh... something's wrong. I went to add emmissive values to the primitive and the render is still black. Things within iRay aren't the same. Something's sketchy. It doesn't appear that my iRay is realtime updating. So, I just now defaulted my iRay settings and get a wash-out. Tweaked shutter speed to "normalize" (800). The glow of the cube is faint. Very faint. I up emissive values 100x, and the glow is unaffected... dull shade of gray. The Box Light from Volume 1, absolutely nothing. No signs of life.
I add a spotlight. The cube's emissive glow disappears. The spotlight is very very very dim. I have to up the lumens 10000x and cut shutter speed to 200 to be able to view a dull shade of gray light on the cube.
This is messed-up.
What in the world could have happend? I do not recall getting any update of DS (if so, I'm never aware of it since I never see one in DIM). Currently I have 4.9.2.70 (WIN-64bit). Do I have to reinstall DS for the first time in nearly 5 years of not having issues?
Whoa! That is VERY weird! It really sounds like you have some off settings in Iray. If you can see the emissive but only if you put the values up WAY high it definitely sounds like something is wrong with the Iray settings.
Ok, before we think about uninstalling (which would create a BIG mess with having to reinstall ALL of your content -assuming you have it all, and likely losing a lot of the freebies you might have). The settings might be the issue. So let's try something. I'm going to share with you my Iray settings - match those settings and see if that fixes the issue. If not we can consider something else, but for now let's eliminate a settings issue.
Here are my settings (which gives me good results and no emission issues):
Try those settings and see if it helps. :)
I left my pixel size alone.
Kept Auto Headlamp-never
Changed Rendering Converged Ratio to match yours (mine was 95%)
Changed Tonemapping settings to match yours (primarily, only the typical camera settings, like apeture, ISO, shutter, since I always have my way of setting-up this)
Changed Eviro Insensity to 2 from 1
I always have map ready (but for sake of the light testing, I remove it to be able to view the rigs)
Leaving my Dome Rotation to 0
Besides that, my settings match yours.
***saves his default scene and runs tests***
***sets Enviro Map to 'none' and SS Time to 11:00PM***
***adds UG Box Light Base, scene is black. adds UGS Emitter Default, still black. adds UGS Emitter Temp 9000, still black. adds UGS Intensity +3, still black. adds Iray Uber Base to his primitive cube, faint light on side of box from 11PM sky setting, nothing on top. deletes UG rig***
***adds emissive values to cube... color white, Iray preview is now showing its typical rendering update but box is dark gray. changes his Luminance Units to watts (his typical unit of measure) and default turns the dark gray to black.changes Efficacy to 10K (turns to very very faint gray) and Luminance to 15K (dark gray). he realizes this should be an extreme washout any other time he applies such a setting. notices no reflection on ground plane. removes emissive value by changing color to black***
***adds Enviro Map. looks good. ground plane looks like rings of Saturn. not typical***
***screen captures this as 'capture01'***
***opens old concept project from April of this year. notices his lights DO NOT look the same. in fact, horrible. there is no emissive qualities like there used to be from headlights and flashlight, in which all lights shown on the werewolf***
***screen captures this as 'capture02'***
***attaches original render from April of how 'capture02' should have appeared, titled 'previz.werewolf'***
So nothing changed or improved with the settings change? That's VERY odd! :(
Anyone else have any ideas for MeatRoots on what might be causing the issue? I don't know what the issue might be - but then maybe I haven't been doing 3D art long enough to know.
I'd put in a support ticket about it to the tech group and see if they can help out. It might even be a known issue that they know how to fix. I'd send them the link to this thread so they would know what your issue is and what you've tried to try and fix it.
I find it super odd that my old project isn't showing the emissives correctly as shown in the above pix.
Thanks a bunch, diva. For now, I can't do any previz till this is figured out. I'll hold out on support ticket till this thread because deadlocked.
I changed (and noted in the starting post) the Discussion Title, since this has come to be an Iray/Daz issue, not a marketplace item compatibility issue.
I also want to note that I had repeatedly done what Tobor mentions in this comment, but to no avail has it solved my issue.
This started as just an issue with only Ultra Genesis Studio Vol 1-2, but in the past couple days it has affected all lighting, including older projects.
There have been no updates to DS nor graphics driver for the month of December, besides installs of newly purchased items.
I will be receiving GTX 1070 on Monday, but there is no way for me to upgrade to the Beta version because it is not made available to me via DIM (all proper settings checked for such). I'm caught in a bit of dilemma now since I'm now on day 3 of not producing any previz work.
I apologize now for my abruptness within this thread, but I'm pretty desperate because of the urgency of getting a project started/completed by Tuesday evening. Like I had stated, it was at first just an issue with UGS, but soon after in the past couple days, it has affected all lighting EXCEPT Enviroment Mapping (besides the weird Saturn rings in the screengrab in an earlier post I made, which is more than likely the Plane being below "the ground" at Default).
If the Dome is contributing to the lighting it may simply be swamping the other lights.
!UPDATE!
Here's the change I have been complaining about... all this time it was the IRAY PREVIEW.
I grabbed my old werewolf project and done a Spot Render. *poof* There it appeared like it should have. So, I created a new project, done like have been with testing (primitives, UGS default rigs) and voila!... Spot Render shows light.
Ok... now... I don't want to necessarily close this thread as being Solved. Reason being... with the Iray Preview, it has always been a WYSIWYG for me. I would use Spot Render for something quick. For the most part, I use the Iray Preview. So... why all of the sudden does the lighting look horrible or nonexistent in Preview? Is there a setting I should be looking at that may have mysteriously altered/defaulted for the Preview?
You're all awesome for putting up with me, especially you, @divamakeup. :D
No. Scene Only or Dome-Scene with no Enviro Map with 11pm settings doesn't help the Iray Preview.
Thanks for repsonding, Richard. :)
!SOLVED!
Ok. I hate when old threads don't include a follow-up, so I'm a stickler when it comes to updates. Here's what I had done to fix my issue.
**I am currently using layout City Limits Lite, modified for two screen viewing, but the routing should still be helpful**
Window >> Panes (Tabs) >> Draw Settings [this opens a window] >> [beside DrawStyle, select from dropdown] NVIDIA Iray
Somehow, my Draw Mode was set to Interactive. I switched it back to Photoreal.
My Iray Preview has now become WYSIWYG. ;)
AHHHHHH This is awesome news! I was stressed about this and REALLY worried that you'd have to uninstall and reinstall Daz Studio - which I know would have been a huge headache!
I'm so glad you found the issue and was able to fix this! That's great news, @MeatRoots ! :)
