IES Profiles

Do people often use IES Profiles? Other than a few freebies online, I don't even know where I'd find IES Profiles. And I almost never think, "The lighting here is close. I'll experiment with IES to see if it helps."

In fact, before I knew they existed, I might diffuse harsh light with a large black plane with its opacity set as needed.

Of course, I ask because of today's JDA HDRI release: https://www.daz3d.com/iray-light-manager There a lot of dialog real estate taken up by IES Profiles. I hope the product does well. But I'm wondering how big an audience it has. (I'm also under the impression (delusion?) that most people own (and use) V3Digitimes' https://www.daz3d.com/iray-light-manager-pro It's 10 years old but already updated to DS6. (And it allows you to update IES Profiles).

Always room for more tools, I suppose. Can't wait to hear if I'm behind or ahead of the IES usage curve.

    There's also this one I picked up recently from the "other" site. https://www.renderosity.com/marketplace/products/172156/iray-light-manager-pro-for-daz-studio-42x they have a DS6 version too.

    I've never edited an IES profile as far as I am aware, I wouldn't have a clue how to. I adjust light source emissions and environment settings to suit my needs.

    Nice find. Only 4.24 but that can change. I like the grouping setup on that other product.

    I wasn't implying making IES profiles. I am sure that's some expensive add-on in something like Maya. (I really have no idea.) Just setting the field is not something, I suspect, most people don't do.

    IES profiles are not used that much in my experience, except for architectural visualization or situations where you want to reproduce the light distribution of real fixtures.

    Ten years ago, I included them in Iray Light Manager PRO (now DS4 + DS6 compatible) because I wanted the solution to be as complete as possible, covering photometric lights, emissive surfaces, and environment lighting.

    For everyday rendering, I suspect most users spend much more time adjusting light colors, intensity, geometry, beam properties, emissive surfaces, and the balance between scene and environment lighting than experimenting with IES profiles.

    By the way, IES profiles can often be downloaded for free directly from lighting manufacturers' websites.

    As for feature requests, suggestions such as more flexible grouping or easier identification of individual lights are definitely worth exploring. I'll look into what might be feasible for future updates.

    I sometimes use IES profiles to get a more specific light.

    You can find IES profiles here https://ieslibrary.com/

    Yeah, I have those. I've poked them into a scene or two. But they never seemed very useful.

    I like much better LUTs (Look-Up Table) and I use them from time to time in Unity.
    They provide many different looks for renders/videos.
    I do not remember if there are some tools for using LUTs in Daz Studio.
    From a Google search:
    "A LUT (Look-Up Table) is a mathematical preset that transforms color and contrast values
    in digital video or images to create a specific visual style
    or convert flat, raw footage into a standard color space."

    Just found it and wonder, if it still works in Daz Studio.

    IES Profiles are built into Daz Studio. That and the product released today are why I brought them up.

    They are not filling the same role as IES Profiles though.

    Have you checked out Emission Profile Master here in the store? The Readme page a link to the user guide. DS4 only, no update to DS6 (yet?)

  • jmucchiellojmucchiello Posts: 2,768

    I own it. The important part of my question is "Who uses them ever?" I know they exist. I've used them. They take up a LOT of real estate in the new script product released today. That's why I was curious.

    If you're referring to the 'osity one I linked to, the PA does have a separate DS6 one.

    Yes. Kinda don't need it any more. Other than tracking down weirdness in a purchased asset, for which the one I own is good enough, my lighting work is usually clean enough to just edit the handful of light objects without needing a whole GUI.

    Yes, I know, but LUTs give some nice visual effect, 
    and I was also thinking, if I need this new Iray Light Manager
