Iray Tutorials?

Are there any tutorials for Daz 4.8 Iray…aside from the ones for sale by Dreamlight (which are really just a guy talking off the cuff)? Seems odd they'd release a version with no visible means of support.

    Umm...it's NOT released yet. It's still a beta. Yeah, the most recent public beta is a release candidate...but still not a real release.

    So? It's been put out into the world, you'd think they'd offer some instructions. The fact that it's beta is irrelevant. If they built it, they must have some idea how it operates and perhaps could share that with those of us trying to kick the tires.

    Is there any documentation?

    Yes, there is. And we’re actively working on more.

    Check out the User Guide and QuickStart Guide that we’ve posted in the DAZ Studio 4.x Documentation section.

    The Reference Guide is also in the process of being populated/updated; updates will be posted over the course of the beta.

    - Render Settings Pane : Editor Page : NVIDIA Iray
    - Surfaces Pane : Editor Page : Iray Uber Shader


    From the first post on the first page of the Beta thread- http://www.daz3d.com/forums/discussion/55716/

    I've done some on my YouTube channel, including the one linked in my signature.

    I also have several on my deviantart blog, including some text versions of the video tutorials.

    How do you know it's just a guy talking off the cuff? Have you purchased the Dreamlight tutorials on Iray? I did... and I learned a great deal about lighting in DS Iray. If you're not finding the info you need free on-line.... and there's plenty of it if you search for it... then you might want to go with a paid Tutorial. I will say, however, that I'm surprised that Dreamlight is selling tutorials for "Beta" software where some things are bound to change, instead of waiting for the final Public Release.

    Anyway, taught me what I needed to know!

    I have bought Dreamlight tuts before and the information is there, but the manner in which it is presented disappoints me…Val scribbling in ineligible writing, and then just talking extemporaneously as he goes through some practices. I'd love him to up his video production quality and use some typed text, some graphics, and maybe a well thought out script. I did get his quicker video on indoor outdoor Iray lighting and do find it helpful.

    Big props to Sickle, her free vids are light years beyond Val's. They are well thought out, organized, and she has a great speaking voice.

    What I can't seem to find is an overall explanation of the fundamentals. For example, Sickle's lighting tut explains how to select all the elements in a scene and apply the iray uber shader. Great, but I'm a relative newb and wonder what the ef a shader even is and why I need to apply it. The models already have a texture mapped surface. Why add something more? What is a photometric light and how is it different from the lights I've been using? Basic stuff, presented like I'm two. That's what I need.

    Great, but I’m a relative newb and wonder what the ef a shader even is and why I need to apply it.

    A shader is the information that the computer program needs to understand how the surfaces should behave. Different shaders have different capabilities. And different programs have different shader languages. In the case of Studio and Iray a fair bit of ground work has been done by DAZ already and many things will convert on the fly. Others may give better results if you apply the Iray uber shader to give it those capabilities.


    The models already have a texture mapped surface. Why add something more?

    But the settings are not optimized. Sometimes you will get good results, sometimes great results and sometimes ugly results depending on the original settings and so on. It has also been suggested (but not sure there is proof) that uber Iray settings render faster.

    What is a photometric light and how is it different from the lights I’ve been using?

    While the photometric lights are very different they are also easier in some ways. Photometric lights are based in real world equivalents. You load the light and then you can leave it a spotlight or change it to a shape. You can adjust the shape to different sizes. Bigger the size and the lighter the shadows it will cast. They also have fall off so the further away a light is the less light you will get on your subject. There are also emmisive lights which are shader based and you just put them on a surface that you want to cast light. It will take a bit to get use to but the good news is much of it you will be able to guess pretty well once you have the basics down. After all everyone knows what a room light by a 70 watt bulb looks like and so on.
