Render trouble

Ted Berlin

I recently purchased Liv hair and the results on my G8F character was terrible! This is actually happenning on other hair renders a well and wondering if i have something messed up with my settings? The renders are in Iray using the default setting. Please advise, thanks

 

Texture preview is first then the rendered iray image

Are you sure the hair is Fit To the figure? Right click on the hair and select "Fit Liv Hair to.." and then select the figure, if it isn't already. The character head morphs appear to be poking through.

 

Also, did you apply Dforce to the dress? Is there also Dforce on the hair?

Ted Berlin

No to both, no dforce on dress or hair. I have autofit to G8F, manually adjusted the fit, scaled the hair big, small, everything in between....still looks the same. I am wondering if my surfaces are messed up? You can clearly see in texture mode the hair looks right, then rendered it looks terrible

Kitsumo

I see Liv Hair fits G3 and G8. Did you load the right version for G8? Not trying to insult your intelligence.

When you say it's happing on other hair renders, are you talking about this same product, or different hair products?

Ted Berlin

Different hair products, they have the same issue as described, looks great in texture mode then renders horrible

Ted Berlin

Is there a way to reset any materials or surfaces that could be causing this? I am just a novice and do not understand why this is happening

Your image for the "rendered iray image" is an iray preview.  Is it possible that you have the Draw Settings for the iray preview set low?  That can sometimes cause problems as it misses some things at low settings.  Try rendering the scene (CTRL+R) and see if it makes a difference, rather than the iray preview.

I tried that, Full render does not change, looks like the preview. I also tried it on the base G8F figure, same results This is very frustrating!

Looks like the image file that handles the hair strands transparancy is not correctly applied or loaded, or rendered.

Try :

1) re-installing the hair (to see if the file was accidently corrupted)
2) Start a completely new scene and apply hair with default G8F (select character, double click hair product)
3) Render scene (to new window) , so not to viewport.

Alternatively 2B) Check if you applied the correct materials : 3Delight if you are rendering with 3Delight, IRAY if you are rendering with IRAY. Your example looks a lot like 3Delight.

Those are my hunches...

No, This is a Iray render with all default settings. I have 4 hair products that act up like this so its not just this one. I strongly feel I have something messed up somewhere and I cant figure out where??? I have tried everything I know to do

Do I need to open a tech support ticket?

So how do I fix that? I tried your suggestions...reinstalled, new scene with G8F, rendered in new window.....

A lot of the OutOfTouch hairs have a preset that needs to be applied first, before selecting the colour. Have you made sure you are doing that?

Ted Berlin

I loaded the hair, then loaded the mat file that stated do this first...then choose the hair color...everything works great until I render it. As I said earlier, this is not the only hair product I am using that does this on render, I feel maybe its a surfaces or materials setting I have screwed up?? Did you notice in the pic how dark the lips become when I loaded the hair...

Ted Berlin

The only thing I havent done is uninstall it and try it again, guess thats what I will try next. Any other suggestions will be appreciated

Ted Berlin

I did a reinstall still the same!

I tried all the things above but nothing has helped. Is the image file you speak of the problem??

Is the hair using Iray materials? Click on the hair, go to the surface tab and look at the top. If it doesn't say Iray then it will need converting to work properly.

Yes, "high quality advanced shader settings for DAZ Studio Iray"  So the hair surfaces settings are not the problem? 

Ted Berlin

I wish I could get to tbe bottom of this..everytime I mention "surfaces" no one can give me a direct answer to my original question, ""could the surfaces settings in this hair be the problem?? If so how do I adjust it? If its a hair transparency issue how do you go about correcting it, thanks

dzDefault the hair surfaces. There should be a shader in your shader presets called dzDefault. Then render and see what happens. If it fixes the transparancy issue. reapply the iray materials for the wig. If it is acting badly again Then its a texturing problem. If when you dzDefault the hair and the same issue is happening, then its something within your render settings, or the geomety of the scene.the reason why your not getting a clear cut answer if its a surface issue or not is because nobody can really know, until we know we know. which means you need to do a little more surface experimentation. We cant do that to your scene on our end. only you can. from the looks of it. It looks like a transparancy issue. Check the opacity maps and make sure everything is as it should be.

I was able to reproduce the effect; so I know what's going on.

For my test, I loaded Genesis 8 Female and gave her purple silk skin to avoid any nudity issues and to highlight any poke through problems. Initially I didn't add any lights to the scene, relying on Studio's default lighting. Then I loaded OOT's Liv Hair. It autofit and parented to GF8 as expected. The Texture Shaded view looked fine as shown below.

So, I switched my main viewport to Iray and the preview render came out looking pretty good as we'd expect.

Then I had a thought. The "Interactive" mode for Iray is designed to be faster, but to do so it sacrifices a lot of the volume functions like translucency and also can have some weird results with layered transparencies. So I went to my Draw Style settings and switched it from "Photoreal" to "Interactive" and ... voila!

So, to avoid this, you want to make sure that at least your render settings are set to Photoreal if you can deal with the weird look of Interactive mode for your Iray previews. If you want the preview to look more like your final image, you'll want to set the Draw Style settings to Photoreal as well.

Ted Berlin

Thank you JonnyRay!!! A simple setting...WOW, I appreciate you taking the time to figure out the problem. 

Thank you Angel_Wings for the dzDefault hair surfaces tip, did not know that

Not a problem. Glad we got it sorted out. Nothing more buggery then spending 24.99 on something and then it dont work right. :D

 

About Interactive mode. There is actually a better way to use the veiwport rendering. If you set the max samples real low it will stop rendering in veiwport. Rather then having it try to render the full image. This reduces the veiwport lag, and prevents a lot of crashes, and prolongs the life of your GPU. If your GPU is already 140 degree's before it even starts the render... All your doing is insuring that you will be buying a new card within a few short years. It's unessesary wear and tear for a "preview"

Great advice, I will try that! My GPU doesn't start hot but during a render its hovering around 150..and the fans have not come on so far
