Just a thought. If you are going to quote an image heavy post could you trim it please. Not evreyone has a fast internet access and others have to pay for their downloads.
First of all - Thanks for all nice comments :).
Your educational renders post may hold the answer to that sheen :) I used metallicity/roughness but will do a test using specular/glossiness instead. I think the one I posted is render number ten or something like that, all with different top coat settings, still without getting the right sheen on her skin. The hand on the first one has been a headache. I've tried the opposite of blurring, to make it even more in focus. Never thought of blurring it...
Thanks a lot :) They are G2F, dialed morphs and a little zbrush, but mostly time, sweat and a lot of censored words... ;)
Thank you very much.. It really helps having friends in the industry
That would be really suckie and limit your internet experience and what you can upload and download.. even my smart phone give me unlimited data. thanks for the reminder
Yep I really like those too Ivy - great work
Thank you :)
The photo shoot part was supposed to be joke,,I'm just bad at telling them. :) The background is an HDRI called "parkinglot" . The scene has mostly white in it , so the glare was so bright it was covering up all the details in the bike and suit. so I had to google how to fix that.Oddly enough I was taken to a photography blog about taking wedding photos.
I started the render yesterday after noon.There was a lot of noise in it near the tires and chrome parts after about 5 hours.So I set the progressive render settings to 15k samples and 100% convergance and went to bed.When I checked it this morning, it had about 13k iterations complete and was 97% converged.I stopped it there because it looked to have all the noise gone.I don't have an Nvidia GPU.I went with an all AMD solution for this build.I doing all of this on CPU so it's a bit slower.
I was reading somewhere that it took over 700 people to create & animate the hair for Merida, I have tried recreating it a couple of times . but it never came out even close to too how diney does it
Thanks :) (Actually, it all began with the chair. I have one too, and it was the chair that gave me the idea)
And I like your biker girl. Impressive with all those details when almost everything is white.
Thank you, Later today I'll give it another whirl with some other Disney Characters , I'm gathering assets for them so I'll see what I can come up with :
Thanks for the tip.
I will look into it
This is the only solution I always use to deal with Iray noise problems, instead of oversampling and have to wait several hours for just a little noise I use this program, which haves a digital camera removal tool which comes very handy. And the best of all it´s now freeware. I´m a heavy postworker and I don´t need more than this to do what I want. http://www.oldversion.com/windows/download/paint-shop-pro-9-0
And, yes, It´s very difficult to find a nice hdri enviroment wich not floods your image with just a flat white colour. The hdris Im using are form the IRadiance Studio hdris, but it are just blabk-grey-white studio lights wich not gives you a nice enviroment if you turn on the draw dome option.
I hope in future updates Iray will let you choose one hdri for just lightning and another for visual enviroment as other softwares do.
Have you tried making your own HDRi's & IDL lights using free stock images, once you do learn how to make your own you have ab better understanding of rendering HDRi images . I'll admit it takes a little practice to learn it
heres a good resource for free HDRi images and tutorials that you can use to create your own. http://www.hdrlabs.com/sibl/archive.html
If you plug an image into the Environment Tab and use it as a backdrop you can plug a different lighting HDRI into the Environment Map under Render Settings
Thats the page I got my parking lot from :) Just scroll down it's called HDR 111.
Look in my sig...the HDR thread lists that and whole lot more ready to use HDRIs...just plug and go.
That is where i got that link from :)
Looks like a 3Delight render to me
My main problem with HDR/EXR is the scaling.I can't seem to get the HDRI to the same scale as my scene.So sometimes the characters are huge compared to the hdri,,sometimes they are extrermly tiny.
...the closest commercial solution I could come up with was using two instances of Bolina Hair one parented to the character the other to the first instance. Looks pretty good, but a pain to adjust and pose. I also had to start with the blonde material colour and adjust the layers manually to get the more "ginger" look. Did one test render of her in Iray using the Pixar Campus HDRI and the hair appeared to translate pretty well.
Looks more like a Firefly render to me...
Scaling shouldn't be an issue if you're only using the HDR for environment lighting. There are some quality generic HDRs that are plug-and-go (Pixar's, for example), but they are rare. In any case, even if the scene images fits to scale, I'd never use it for a render. That would be like loading V4 stock, and hitting the Render button. HDR image renders may look unique to you now, because the products are new. But guaranteed your renders will have a same-ol, same-ol appearance in just a few months.
It's much better to find a good plate (less used stock photo, or take it yourself) and use it in D|S Panes->Environment, or put it on a backdrop (shadows are not an issue if done correctly), or render with a transparency and add it in post. Really, other than for testing, I can't see the value of rendering a commonly-available HDR with the Dome draw on. What's the point of it if you art looks like everyone else's?

That isn't the HDRI that is doing that it is the Dome. If you use Infinite dome then the HDRI fits it but if you move the camera away the image stays the same but the objects get smaller. Using a Finite dome and sizing it to fit the figures is the way to keep both at the same scale.
If you switch to finite dome, you should be able to scale things...are you using the HDR for both light/backdrop?
you can change the scale of the HDRi under the render settings , change your Environment to Finite dome with ground instead of using Infinite dome and scale then once you change that setting you will see a bunch of new setting become available to you
I will usually go from 100% to like3% to start with and work my way from there
double post sorry
This explains what happens with Finite and Infinate Domes.

...same here as well as for character/prop placement In the Merida/Pixar test I had to mess around with scaling her to get the proper size relation to the brick plaza where I wanted her to be. When I first loaded the HDRI. she was standing on the steps leading to the grassy area.
Here are two images using one of my own pictures taken in the NW of Scotland.
The first is the original done in 3Delight the second was done in Iray.
