How to make IRAY look more like 3Delight?

in Technical Help (nuts n bolts)

 

The image on the left was rendered in 3Delight. While the image on the right is a mirrored version of the same image rendered in IRAY. Is there anything that can be done in IRAY to show more of the veins and definition so that it looks closer to the 3Delight version?

I was told that changing the surface settings would help accomplish the desired results but I'm not sure of which ones and I tried trial & error but there is just too many of them to find the correct combination.

Any help that can be offered will be greatly appreciated. Thanks in advance.

    Were the veins in the 3Delight version created with displacement? If so, you need to be aware that Iray does not handle displacement the same way the 3Delight does. In Iray, you need dense geometry to get crisp definition from displacement. You can try increasing the character's Render SubD Level in the Parameters pane. Note that you first need the Mesh Resolution to be High Resolution. If it is only Base Resolution, first use Edit/Geometry/Convert to SubD in the Parameters pane context menu. Or you can use SubD Displacement Level in the Surfaces pane. Note that in order to even see this surface control you will need to use an Iray shader on the character's skin surfaces, load the displacement map and set a displacement strength. Don't immediately set either SubD level too high. Start with 2 or 3 and work your way up to what your computer can handle. It becomes untenable quickly. Also be aware that there seems to be a feature/bug in Iray that limits the surface SubD Displacement Level to 2 in some cases, so that method may not work well.

    Funny, I would have guessed that the iRay was 3DL and the 3DL was iRay

    Thank you for that but that is completely beyond my technical abilities. Thanks anyway though. Greatly appreciate it.

    I do like the 3Delight version better but there are other aspects of the scenes which work better with IRAY. For that reason, I want to stick with IRAY but I would like to get the IRAY skin tones to look more like the 3Delight version but it appears that in order to do that is way over my head.

    But you should try the advice to increase the SubD Level in parameter tab. As soon as I have read your discussion above I tried it (set it to 2)

    It was the first time ever, I saw the crows feet I usually apply

    Most HD morphs require SubD 2 or 3 to show up. Some are even modeled at SubD 4 I believe. I don't know how to tell how much SubD to apply for any given morph that is sold as HD. I usually try 3 if my computer can handle it for a given model and scene. To see the HD morphs in the viewport you have to set the View SubD Level. That can make your viewport sluggish, though. If you don't need to preview them, but only want them in the render, just leave the View SubD Level low and increase the Render SubD Level.
