A few days ago Ockham posted a thread asking about a silk hosiery hosiery texture. A couple other people showed interest, particularly Acadia. Since Acadia is always so helpful, I decided to do a massive freebie. Here it is.

Attached is a Poser material file, stockings.mt5. I had to add ".txt" to be able to post it here. Save the attachment as stockings.mt5 (or any name you choose) somewhere in your materials runtime.

The purpose of this shader is to simulate the appearance of various styles of hosiery directly on your figure's legs. Of course you can use a clothing prop, but those often have all kinds of complications with poke through. Plus, you can't even find any for some figures.

So here's a solution using your figure's legs alone. Of course it works best if we can't see the figure's toes. The reason is this shader will be applied to the leg geometry, instead of a "sock"

over the foot. The toes will look like they're in a glove instead of a sock. Also, this isn't going to work too well if you're looking for stocking tops on the thighs. But if your character is wearing shoes and a skirt or dress, this is a great solution.

There is a long of math in this shader. You don't need to worry about that. I've tried to make it as simple as possible to use.

There are only 4 parameters you need to deal with. Each of these is in a clearly marked node in the top left corner of the shader.

I'll be posting quite a few replies to this thread with plenty of instructions and hundreds of demonstration renders, so please hold questions or comments until I say I'm done.

Ready?

Here's something else you'll want to download. I chose twenty nice colors to help you get started with great looking legs. This image shows them. We're going to use this in the shader as a handy color picker. I'll show you that shortly. Save this image to your computer. Make sure you remember where you put it. You'll need to load it into your shader.

Some figures, such as P6 Jessi, have one giant material zone for the body, arms, and legs. This is unfortunate. If you're working with such a figure, I suggest you'll want to create a new material zone for the stockings.

Load your figure. Bring up the Group Editor as I've done here. Select one of her leg parts.

With the part highlighted, click on the "Assign Material" button. In the dialog, type in Stockings. Hit OK.

Keep doing this for all the parts you want to be covered by stockings. For the remaining parts, you don't have to type in the material name. Just pick it from the pulldown list.

Once you've done this for all the parts, you can then choose my material for the "Stockings" zone.

I suggest you save this modified character back to your runtime so you won't have to do this again.

For figures, such as V3 and V4, that already have leg zones, you won't need to do this. However, you might want to anyway, so you only have one leg zone to deal with. Just choose each part and assign them to the same material zone.

For V4, the upper thighs and buttocks use a different color map than the legs. You cannot use a single material for both areas. You'll have to do any material loading and editing on two zones for V4. You may also have to choose individual polygons to keep the stockings from covering the entire torso.

Once she's set up, do experiments only with the legs. Once you have all the adjustments finished, copy the settings to the other zone for the upper thighs and buttocks.

OK so load my shader. Again, there are a lot of nodes here - don't worry about them. Just pay attention to the ones I've left open.

See the Image_Map on the upper right, called Color_Sample? Load the 20 sample colors you saved earlier into that node. You can then use the node display widgets to hide the parameters and show the colors.

See the second Image_Map under that called Skin_Color? You need to load the correct color map for your figure into there.

This is what it should look like after you load your skin color and your color sampler.

So let's talk about the parameters.

Stocking_Color: This should be obvious - what color are the stockings?

Denier: Real life stockings talk about Denier which is a measure of how dense the material is. I've tried to make this parameter work close to real life.

A rough rule of thumb for Denier is:

Sheer fashion hosiery: 5 to 15 (most real ones come as 7, 10, or 15)
Panyhose: 20 to 40
Tights: 40 to 80

Sheerness: I've rolled up a bunch of physical characteristics into this one parameter. It captures the difference between opaque materials like cotton, versus in-between like silk, to highly translucent and shiny materials like nylon. So sheerness will take all this into account. A rough rule of thumb for Sheerness is:

Matte = 20
Soft = 40
Sheer = 60
Super Sheer = 80
Ultra Sheer = 100

Of course you can use any numbers in between for these two parameters. I'm just giving you a few key values to keep in mind.

Finally there is Glitter. This will make little sparkly highlights. This also follows a 100 point scale, but you can turn it even higher. Note that for the best glitter, use a Render setting Min Shading Rate = .2. Values of .5 are faster but not as fine. If you're not using glitter, Shading Rate = 1 is fine, as long as the rest of your scene is ok with that, too.

The color sampler is really convenient. To pick one, click on the stocking color node where the arrow is. This brings up the Poser color picker. Then just click on the sampler. I show an arrow where I'm picking the Pink color.

This is after choosing the pink - it's now copied into the stocking color. Note that you can use the color picker on anything on your screen. For example, you could open a picture of some real stockings and just click on them. Be sure to click on the welt (the dark part around the thigh) not the translucent leg part. You're trying to pick the true color of the cloth only.

So now I've explained the parameters and how to set them. Now I'll show you a huge bunch of renders. You can use these as reference charts to be able to figure out what values you want to use.

Here are the first ten colors, reading left to right, top to bottom, on my color picker.

Black, White, Gray, Charcoal, Cream
Bone, Khaki, Taupe, Nude, Cafe au Lait

These were rendered with Denier=20 and Sheerness=40.

Remember! These are just samples - you can use any colors you like. You can also design your own color picker and load that into the Image_Map node instead of mine.

Ok now we'll do some more charts. A bunch of them. In each of these charts, the Denier will be the same. There are ten renders, using Sheerness

10, 20, 30, 40, 50,
60, 70, 80, 90, 100

Here's the first, Denier=10.

Now some charts where the Sheerness stays the same, and Denier changes. There are 8 pictures in each, with Denier

10, 15, 20, 30
40, 50, 60, 80

Ok I'm done. You're welcome to add questions or comments.

I did all those Denier, Sheerness, and Glitter charts in black. If you'd like to see a chart in some other color, just ask.

I can make them in minutes, now, because I found a cool way to automate the process.
