Rendering Leo 7 in Iray makes DAZ Studio crash

I guess I haven't used Leo since I switched from using 3Delight. I've uninstalled and reinstalled. I've tried with and without the Legacy shader. Instant crash every time. Does anybody know a workaround? Or is Leo for 3Delight renders only? Thanks for your help.

I don't have Leo 7 otherwise I'd give it a shot. But his product page does list Iray material settings.
I've tried both the Iray shaders and the 3Delight shaders and he crashes Iray renders with both. He works OK with 3Delight, though, so I guess I'll use him with older stuff.
Leo 7 appears to have several mpas in .tif format - the current version of Iray does crash with some .tif files.
/Runtime/Textures/DAZ/Characters/Genesis3/Leo7/Leo7_Arms_NM_1004.tif
/Runtime/Textures/DAZ/Characters/Genesis3/Leo7/Leo7_Face_NM_1001.tif
/Runtime/Textures/DAZ/Characters/Genesis3/Leo7/Leo7_Legs_NM_1003.tif
/Runtime/Textures/DAZ/Characters/Genesis3/Leo7/Leo7_Torso_NM_1002.tif
Please report this to suport, but in the meantime you can fix the issue by saving those images in another format (PNG, perhaps) and then using the Surfaces pane to apply them in place of the tiffs (they are all normal maps, for the arms, legs, body, and face groups.
...interesting, I just did a render test in 4.10 and no issue (2 min 15 sec). Used just the base character (no additional morphs) with hair, clothes, lighter skin texture (Beautiful Skins Iray) and a HDR set (Fast Production Lights).
Also ran a test in 4.12 (1 min 41 sec) and no crash either.
Leo also does have Iray materials.
Are you using 4.15.0.30? As I understand some maps from older content have been causing it to crash.
You don't even need to do a render. DAZ Studio 4.15.0.30 will crash if you load Leo 7 with an Iray viewport.
Well this is becoming a challenge. I switched .tiff to .png. Those crashed. I switched .tiff to .jpg. Those crashed. I decided to clear the normal channels and got Error in Rendering. So DAZ didn't crash, it just hung up and I had to close it. I wonder if I still have a 4.12 installer kicking around. Off to talk to support. Thanks, everybody.
Hey! Guess What! The world's least observant person (that's me) just noticed Leo HD next to Leo, and that doesn't crash. Still going off to talk to support, though.
I would think any figure would crash DS if loaded with the iray drawstyle veiwpoint on since that takes quite a few resources. I wouldn't recommend anyone using that drawstyle as the default
No problem Out of here rendered in one minute.
This worked for me. Thank you, Richard.
Ooo. How'd you do it? I tried it but it didn't work. I converted on Gimp, but I wasn't sure what to do when it started to talk to me about extra channels, so I left it on the default.
I saved them in Photoshop as png. Then I just applied them to the normals channel in surfaces.

I did a larger render in 4.14 (Nvidia Iray Preview) much faster 36 seconds but it did crash 4.15
One difference between Photshop and Gimp, I guess.
...the HD version doesn't crash? I would think it would be the other way around.
Yeah, definitely going to stay clear of 4.15. They need to get in touch with Nvidia to solve these issues before 4.16 as these incidents apparently impact both workflow and the frustration level. People shouldn't have to be converting Iray shaders to work Iray.
Did you change all of the references? The HD would not cuase the crash because it doesn't use the normal maps, which is what the tiffs are.
I took all the .tiffs to Gimp and exported them as .pngs. Then I opened Leo in the surfaces and changed all the normals to the new .pngs. Then I rendered it and it crashed. So I took all the .tiffs to Gimp and exported them as .jpgs. Then I opened Leo in the surfaces and changed all the normals to the new .jpgs. Then I rendered it and it crashed. So I gave up. Then I noticed that oh my, I have Leo HD. Where I got confused was when Gimp came up with this:
I wasn't sure what do do about the extra channel, whatever it may be, so I left the radio button where Gimp put it. I'm guessing that's why your good advice didn't work for me.
You image doesn't show in the post, only in the edit box. Please attach it to the post.
Tiffs often have an alpha channel, embedding that in the PNG gives it transparency which is not an issue. The crashing seems to be with a particular type of tiff, so I suspect you had missed one of the normal maps in making the changes.
i installed and tried it. Hit render and the program crashed just vanished. poof. DS gone.
I converted the tif files into png and applied via surfaces . Instead of crash I get "error during rendering" box. I hit OK and it tries to render but nothing happens it just sits with spinning circle. I have to close the program to stop it. It appears its looking for something and not finding it. I don;t know how the mat files are made up/loaded. I assume the mat file, or another process, is searching for something its not finding using the png file.
Also tried to just eliminate the normal map and this did not avoid a crash either. Changed maps to none in surface editor. then tried to change the setting from 1 to 0. neither worked to stop a crash.
AHA ..just turned the normal maps off within the figure/material folder in smart content. IT RENDERED
I also tried. It DID work on a Mac, but instantly crashed on Win10. Same rig, just one time started with macOS and one time with Win10. CPU rendering in both cases.
OMG, Richard I could kiss you! I have been having this problem since April and been back and forth with support to try and figure it out. Finally you have the answer that fixed it! Thank you, thank you, thank you! Now I just have to decide whether I want to go back to using Leo's textures for the character or continue using Scott 6.
Ooops. I'm still learning about forums. What confused me is now attached. Which of those buttons should I have hit?
They don't really matter - I doubt it would make any difference to the result (especially if you saved to jpg).
In that case, maybe I did miss switching out one of the four channels. Looks like other people got it to work. I'll try it again.
What version of Daz? I have 4.15.0.2 and just did a quick 3000 x 3000 render of Ophelia 7, who has the same type of .tif normal maps as Leo 7 and she rendered fine. The .tif files used with G3 characters are compressed differently than the ones that come with newer characters and are ginormous (~50MB each) so could it be an issue with that?
I tried to render him with the .tiff files in 4.15.0.30 and it crashed. I changed them all to .png (Affinity Photo). It's rendering.

Well I shant be updating to that version...sticking with 4.15.0.2
DAZ will have to update all the products with tiff files then
sitting under my umbrella in case a pig poops in my coffee as it flys past

this seems to a problem localized to a very small subset of products...
