I was just wondering if anybody knows how to simulate the fabric of Wolfords or other shiny hosiery.  I've purchased some good textures, but they tend to look like they are painted on and don't reflect the light. 
The hosiery objects that I've purchased tend to be too bulky.

Thank you.

Xan

You could probably get that result with shaders in the material room.

Make a post about it at RDNA in their Node Cult forum.

I'm working on it - not quite right yet.

This is kind of tricky. Do you want to use a clothing prop for the tights or mix this right into the skin shader. There are pros and cons.

Mixing with the skin shader avoids poke through, but is a bit more work on the shader. A much simpler shader can be used with a clothing prop, but they often don't track the leg deformations when posed.

I'm using the mixed skin/tights shader approach here.

Unfortunately I'm not going to be doing Poser at all this weekend, so the finished shader will have to wait until Monday. Sorry.

Thanks Acadia.  I will check out that other forum as well.

bagginsbill,

That looks like what I've been wanting to do.  I haven't figured out how to manage the poke-thru of the objects, so I've been trying to figure out the right way to apply the correct texture from the hips down.  Let me know on Monday how your shader works out.

I suggested the Node Cult Forum at RDNA because that's Bagginsbill's hangout for shaders. He's not only our resident node guru, but also RDNA's.

But you still should check out that forum. Lots and lots of great information there for all kinds of shaders.

Hi Acadia,

I did check out the other forum and it looks like I've got a lot of learning to do :) 
Between this one and that one, I'm going to have some late nights.

Thanks again,

Xan

And this one!

Some of the links were changed when the forums were updated to php. So scroll down for fixed links and also scattered updates.

Here are a couple of different ways that I use to get that type of effect. 

Chris Cox



  chriscox    ( ) ( posted at 11:36AM Sun, 09 September 2007  · @3068328


This is the material use for Vicky 3.   The material for Vicky is fairly simple because she has multiple material zones allowing the legs to have a different material than the rest of the body.

Here is the material used on Miki 2.  Miki is more complicated because she only has one material zone for much of her body.  I had to use a Blender node and a mask to allow diffent effects to applied to just her legs.

Hi all. I'm still working on it - Poser has some problems with fine-grained bump maps I'm trying to find a workaround for.

In the meantime, read this:

http://www.neilblevins.com/cg_education/aniso_ref/aniso_ref.htm

It describes the phenomenon called anisotropic reflection. Stockings do this big time. Rather than me explain all the details - that article covers it very well. We'll be using the Poser Anisotropic specular node to do that effect. Chris's shaders above are very good, but missing this key effect. Chris also didn't do anything about the sparkly/glittery effect. I'll be back.

The image is one of my latest test renders.

Using black tights instead of beige, the importance of the specular glitter+anisotropy is even more evident.

And here is a test render showing the problem with the weave node as a bump map (or any fine-detailed bump map for that matter).

I have an open bug with e-frontier on this issue. It has stopped me from posting many interesting materials because it really messes things up. A general solution still eludes me, but I'm working on one that should help with tights.

Be sure to click these renders to see them full size.

Thanks Chris.  I've messed around a bit with the settings that you provided and got some interesting results.  I'm not sure if I'm doing it quite right yet, but I'm practicing.

Thanks for your help as well Bill.  What settings are you using to achieve your results?  I like what you've done!

I can't seem to get the fine detail.  When I've tried using the noise nodes as described in the "sparkly velvet dress" lesson, the white dots end up being too big.  I'm sure I'm missing a small setting.

On this A3 render, the legs look more like stone than stockings.

Thanks again!

Xan

Okay, I tweeked a few settings to get this result.  It's not exactly where I want it, but I'm getting there!!

xanaman,

Oh ho! I did not know you were a node wizard. Here I've been slaving away trying to work out every detail for a neophyte, and you go and do it with just a few clues. I see from your last render that you worked out how to use the anisotropic node correctly. That looks great!

OK then I'll speak to you wizard to wizard.

The Noise node is a peculiar thing. I find that to get fine litte glittery points instead of big white splotches, you need to use aggressive render settings - which costs time by the way. Change your min shading rate to .2. Here are a few more tips on glitter:

  1. Experiment with lowering the Noise node scale.
  2. Set the Noise node min = -2, max = 1. This produces far more sparse speckles. You then need to throw away the negative values - plug the noise into a math-Clamp node. Now you're only pulling out values from 0 to 1, but much more sparse. Run that into your specular value for glitter.
  3. Insert a math:Gain in front of the clamp+noise. Try gain of .8. This will emphasize the glitter and make it even more sparse.
  4. Try the Blinn node as well as the Specular node to produce the glitter. Pros and cons here. The specular is easier to control/understand, but the Blinn will give much more reflection when doing rim lighting.

For the anisotropic node, I used U_Scale = .07 or .08, V_Scale = 1. The strength was between 1 and 2.

I'll be posting more.

Oh forgot to mention, the Weave node isn't strictly necessary, but it does add a lot of detail as you get closer to the surface. For smaller renders or full body, it probably doesn't matter a lot. Still, I like it when a shader works well over all viewing distances, so I'm still trying to figure out how to use it for stockings.

Bump produces artifacts. I'm looking into just using the weave as a multiplier on the color blend (skin to cloth blend) and the speculars.

Thanks Bagginsbill!

I wouldn't say that I'm a wizard, but I pick things up quickly.  A wizard in training, perhaps :)
I haven't really messed around with nodes before.  I guess I was always worried that I would mess something up, so I appreciate any suggestions that you have to offer.

To get the effect on my last post, I used a combination of both Chris' suggestions and the ones on the runtimedna "sparkly dress" posting.  I'll post an image of the settings tonight.  I'd like to see if there is a way to combine techniques to have the shiny effect with glitter.

Thanks again!

Xan

Here are the settings I used for the effect above.

  xanaman    ( ) ( posted at 11:56PM Wed, 12 September 2007  · @3070756


This one is with the anisotropic node.


  xanaman    ( ) ( posted at 11:58PM Wed, 12 September 2007  · @3070757


This one is with the specular node.

Wow! That looks awesome!  I may just borrow that effect, hehe  Actually, I definitely will! :)

Hehe...
Thanks Acadia.  Anything I can do to help 3D models have sexy legs :)

My next adventure is to figure out how to get the same effect with outfits that go higher up on the hip.  I know there's a way to mask off the texture so that it doesn't go beyond a certain point on the torso, but I haven't had a chance to read up on it yet.  Any quick suggestions will be much appreciated.  I will try the settings Chris posted for the Miki model.

Thanks everybody!!

Xan
