    Such great images :)

    The images are nice. :-)

    Someone mentioned use of HDRIs.  These lights -- the ones I've tried -- do work with any HDRI.  "Scene Only" setting just needs to be changed to Dome and Scene.

    This product is amazing and amazingly easy!  Used multi-light fx preset, head & shoulder camera, iray high render preset.

     

     

    I tried out the multi slight fx preset.... one issue was that it overwrote my current scene, so I learned with those to right click and merge into the scene.  Luckily I had just saved my previous scene so nothing was lost.  Next issue that came up the render settings were set way to low so I was ending up with a very grainy render.  It was fast, like under a minute, if that.  Once I set up the render settings back to default I got a much longer render but all the graininess was gone.  No image I'll post but it's feedback to the Colm in case he's reading these posts.

    Hey, Wolfie -- did you find the different render settings for Render Studio/IRay?  They're...next to last main heading, I think.  There's draft, for quickies, then variations all the way to ultra high. :-)

    OH.  Didn't see those.  Still foraging around the folders.  So much to try!  lol  Thanks Jan! 

  • RAMWolffRAMWolff Posts: 10,343

    Hmmm, now I'm getting a huge blowout of the background.  Not sure where to look for that on how to turn down the intensity of the lights.  I checked to see if the headlamp was on but it's set to off, not auto.  So not sure why the lights are blowing out the cove backdrop so much.  indecision

    You're welcome, it is one big light set. :-)

    About the cove light -- if there's a background light in the scene, it might be the one that's glaring on the cove.  The first light set under "Lights" is the background light set.  In the materials folder, there are different profiles for the backdrop light.  You can select the background light (not the controller), then change the profile.  Or just turn down the luminance and luminance efficacy -- think that's what it said in the tut.  Luminance/luminance efficacy. 

    I hope this helps. :-)  Several people helped me, when I was strugglin' w/the catchlight in the eye, so I hope I can pass it on.

    Hi Jan,

    Thanks for the adice.  Hmmm, the Background lighting is not helping too much.  I just started a render and here is the first results.  There are NO OTHER lights in the scene besides the background light.  It's weird right!

    Beautiful. Which skin texture is this? I like how the skin appears to have layers.

    Are you sure you have no other lights or mesh lights in the scene as when I render just using a back light & the cove the figure is not lit at all (as attached)  This is on scene only

    That is intense.  I got an effect like that with one of the "hard" bkg light material profiles, but it went away when I changed to one of the "diffuse" mats.

    From what I've seen, the background light shines downward, between the figure and the cove.  You may be rendering the direct effect of the bkg light on the floor.

    The "shadow" scene has a sitting prop.  Maybe you could load that up and see what sort of bkg lighting is in that scene, if any, since your model is low to the ground.

    Edit:  There's no bkg light in the "shadow" scene.  Maybe you could change out the backdrop on the cove and use that scene?  Just a thought -- good luck. :-)

    Tried just about everything to get a good render.  Ended up turning off the backdrop (thanks for the suggestion hon) and then just repositioning the background light to shine on her fully and loaded in a specular eye light, moved that to a position more to her ground position.  At one point I tried using one of the cameras that were included for a ground shot.  Every render turned out black until I removed that camera.  I looked all over in the Camera tab to see what was up but I just don't know enough about that to know what I should have been looking for to correct that.  I'm good at making stuff but horrible at all the presentation end me thinks!  lmao! 

    Here is one render I just did that I'm sort of happy with.  The skin looks a bit dull though...

    That is weird, Wolfie.  Especially the camera thing.  I don't think I've tried the ground cameras, though, so can't testify for them.

    Some of the lights will lighten skin.  I end up using the fill, at lot of times, because it's soft.  I usually turn the key lights down a notch, if they're in the scene.

    And for final renders, I use the "high" setting, at least.

    I'm sorry you're having a frustration.   

    Edit:  OK, I just tried the ground cameras, and they all render the sitting prop in the shadow scene without a hitch.  I can't figure what happened w/your scene, unless a big light crept in front of the camera somehow.

    I gotta say "thank you," though. :-)  I just found out why I couldn't get my gobo effect to render the way I wanted it, a couple of nights ago.  I had put the gobo on one of the lights, instead of the Projector. blush​  I was testing out the scene with lots of colors, saw the Projector, and the light dawned -- so to speak. ;-)

    Back to your scene -- I've not talked to Colm J much -- just once at DNA, maybe.  But he was very nice.  Maybe you could pm or message him on FB, and he could help you out?  I know you're smart -- and I know this light set is very good.  So I can't think why things aren't working for you.

    That's what happens for me, too. :-)  The background light only lights the background -- not the figure -- when loaded at the default positions.  

  • Hi Ramwolf.

    Sorry to read that you are having so many issues. Have you read the PDF that comes with the product? It covers many of the issues you have mentioned such as how to turn down the intensity of the lights and render settings. There is actually a whole set of different quality render settings included with the product. The one you used in the image is the 'Draft' one which the one the pre-set scenes are using. The draft setting is only meant for test renders when you are setting up your scene. You should use one of the higher quality ones for a final render.

    The issue with the blowout on the lights is more difficult to help you with. It looks like you are using the Infinity cove. The background lights are actually meant for the 'Background and Floor' prop and not the cove. Although there is nothing stoping you using the background wall light with a little adjustment on the cove.

    Here is my suggestion. Can you send me the scene file? It must not contain anything only the Render Studio Iray files that you are using. So I would need a scene with all the lights loaded and the background you are using only. It should zip up quite small so you may be able to send it in email. If not can you sed me a dropbox link?

    Please send it to [email protected]. Please don't PM me here with the info as I don't check these forums often enough. Bea has to tell me what's going on lol.

    I will do what I can to help but I may not get to it until Monday as I won't be back at home until then.

    Colm.:-)

    Hi Colm.  Can you please tell me where that PDF is located?  Is it in Documentation or in ReadMe's?  Allot of merchants will set up a little icon that will open up the PDF in the main product folder to keep things findable.  Thank you!

    I'm not Colm, but -- I had to get to the pdf by opening the zip file, Wolfie. It's in ReadMe's. :-)

    I don't know where it'd be if you installed using Connect, if this installs thru Connect.

    *Bea, CJ says he doesn't come to the forums much and you tell him what's going on -- can you ask what the Infinity Cove is intended to be used for?  Is it just for a backdrop, or does it generate some sort of lighting?  Thanks!

    Hi Jan, the infinity cove is so far as I know just a backdrop

    I'm back from the gym, errands and lunch.  

    If Colm releases more and more stuff, he might consider doing a ReadMe>Colm sub folder so his ReadMes and PDF's can be easily found.  Ghahhhhhhhhhh

    I manually downloaded the zip and fetched out the PDF and renamed it "Colm's Render Studio iRay User Guide.pdf" for easy finding....

    This is a fantastic product.  Colm always makes quality products and his customer service is great.

    How does the tutorial setup work so that you can access them inside Daz Studio?  Us Poser folk are trying to learn DS.  I'd love to know, thanks.

    I was just going to say...if installing thru Connect will let me pull that tutorial up inside DS, I'm going to re-install. :-)

    I am constantly overlooking things, and a quick reference would be handy.

    Jan, I could be wrong but I don't think you can. But let me know

  • mrposermrposer Posts: 1,134

    I just have the Poser version of RenderStudio 2014 but the Infinity Cove is shaped like the Paper Roll Prop for those familiar with those InaneGlory's Photo Studio products only much bigger in scale. I think its more to add a mood... dark, light, or neutral materials for the Render..and leave alot of room in front of it for positioning lights... whereas the paper roll is more of a portrait backdrop with usually many material options offered.

    I remember Photo Studio.  :-)  That's a good tip, using the cove to set a mood.  That is exctly what it's used for in the RS/IRay shadow scene, looks like. :-)

    I'll take your word for it, Bea. :-)  I've got the pdf on my desktop anyway, for quick reference.  That works.

    You can always manually install files to a readme or whatever folder you want, as long as the folder is in the content manager path.

    I debated over the recent "Scenes" add on, then decided to go for it.  Glad I did. smiley​  It's real convenient to set up a scene, then import a RS scene subset for lights.

    Also, maybe I can learn something from the placement of lights in these subsets.  Haven't test rendered all of them, but I liked the way the Skin FX test turned out, even at Med Quality Render settings.

    I was also playing around with some old MFD textures that I found thru Connect, to see if they'd work w/the MFD for G3.  And they do.  I added the IRay ubershader to the dress and hair.

    Big plus -- the catchlight in the eye appeared. :-)
