Finally trying Iray for DAZStudio 4.9

Finally trying Iray for DAZStudio 4.9

Hi folks,

Yep, still busily working on novel. But I find that without my forays into art I feel empty. Yes, I need both writing and visual art.

So I figured that I would play a little in DAZ Studio. This was frustrated for a week when my PostgreSQL database (the thing that manages all my content in DAZ) decided suddenly not to work. Stupid message about not being able to connect user. I Googles this, found it to be a common problem, tried all the proposed solutions and found that they appeared useless, and then did a complete delete of everything even vaguely DAZ related on my machine with a complete reinstallation and voila!

So after all that I figured that I would try the Iray renderer that NVidia now supply.

Now let’s be clear – I did actually fiddle with Iray for about an hour when it first became part of DAZ. At the time I decided that I loathed it because I could not get it to do what I wanted it to do. BLAH!

Well, this time I decided to actually read an online tutorial instead of just experimenting.  Because I love to focus on lighting in my renders, I ended up using at a tutorial at entitled “The Biggest DAZ Studio Iray Secret To Fabulous Lighting (Yours To Copy Now)”.

It really made a difference.

Anyway, because I was only intending to muck around to learn Iray I did not put much effort in designing the scene. Just a Genesis female, hair, cape and skirt (yes, I know, there’s no top and I am a dirty old man). Put one of my slightly modified textures on her face (more freckles = more realism). Posed her alluringly. Reduced the glossiness of her hair and changed reflective colour to a deep gold. Threw a random architectural object behind her.


Took around 15 minutes to set up as described.

So this is the scene from the camera before rendering.


By the way, I am using two spotlights. I wanted her far side illuminated and a partial illumination of her face. Film Noir meets Caravaggio.

Once I got the render I realised that I needed to do very little post-processing. Indeed, all I did was add an incredibly subtle (practically invisible) cloud of brown dust between the model and the light source (and my signature) in Photoshop.

So here it is:



This was well beyond my expectations. I think I love Iray.

Greg signing off and thanks for reading :)




  1. Nice work Greg. I’ve tried iRay a few times now but keep coming back to Reality and LuxRender.


    1. I think each renderer has different qualities that meet different things I am trying to achieve. Still love Luxrender though and still keeping it up to date :)


  2. Looks great =)

    BTW here’s a thread that you may have seen… or not; either way, it covers one of those essential aspects IMO:

    And this is a companion article which is only available as a googletranslate from Russian unfortunately…

    The gist of it is that you get the most realistic results when your colours are tuned down to more real-world-like albedo values (setting the colour swatch next to the texture to use something like RGB192 does the trick).

    Oh, and I also happen to have a sort of “magic skin preset” that isn’t really well-tested enough to be released, but in my limited runs it’s been pretty consistent over a range of textures and figures. If you are interested, I could shoot you an email.


    1. Hi :) Sorry for taking a while to respond to this. I actually did not see it for a while. I have been using my phone to check things and not my PC because the big monitor was hurting my eyes after the operation. For some strange reason my android app does not tell me when there are comments, only when there are likes.

      That first link is great. I already knew some stuff there, but other was new to me. Really good :)

      The second link is good too. The translator seems to work fine (albeit I have only skimmed through the article so far because I am still not pushing my eyes)

      I am intrigued by your magic skin preset. Would love an email. :) Thanks muchly
