OK so here is the thing. I have a second skin lingerie for a character I am making and it is silk/satin. In the picture you can see it :) 

I want to make JUST the lingerie part look shiny, is there a way of isolating that part with nodes so that ONLY it looks shiny and not her legs or neck or any body part for that matter?

You need a mask and blender(s).

A mask is like a transparency map, but you don't use it for transparency. You use it to identify areas of a prop or figure that belong to one of two different materials. You use black for one area, white for the other. 

Once you have a mask, you look at the two materials and compare them, in preparation for combining them. Where they are the same, the combination is trivial - use the value or node that is common to both. Where they are different, you place a Blender node, and set or connect the two values in Value_1 and Value_2. The mask goes into the Blender's Blending input, and set it to 1.

So - if you have two different color maps, blend them. The mask will decide where to use each.

If you have two different specular nodes, blend them. The mask will decide where to use each.

If you have two different bump maps, blend them. The mask will decide where to use each.

If you have the same node but a different number in a particular parameter, blend them - use two math nodes to hold each value and plug those into the blender.

OK, I know this is going to sound irritating, but is there anyway I can get a screen shot of what you are talking about?

Here it is.

The way I set it up allows you to use any character skin with the Vampirella suit.  You can do the same by following the example given in the file.

You might also want to use your Mask as a Displacement Map so that your silk/satin will look slightly raised from the skin.

I am about to give up on this totally. I followed the instructions and it doesn't look like anything. Thanks for trying guys and thanks for the information. This is what I ended up with. Looks more like velvet than silk :S

There should be some kind of shiny nodes in your node setup, if it is to look shiny (like silk). Currently there are only masks and textures (and the specular value is 0). How did you manage to get the large letters into the node-titles?

That is my problem, where does the shiny node go so that only the silk part looks like silk and not the whole body??

Oh the large letters is just photoshop :)

If you don't know how to make either shader, then you won't know how to make a shader that does both.

You don't have a reasonable skin shader and you don't have a reasonable silk shader. Specular effects are prominent on both although they are very different.

In your original post you asked how to put the shine only in some places not others. I didn't know you should first have asked how to put shine on anything at all. 

Now where to begin and how far to go? Hmmm.

Well - first I'd use a Blinn specular node, white, .35, .4, .4 on the values, for the skin. That would go in the Alternate_Specular channel, with the channel value set to white.

For the silky part, I might use the Anisotropic specular node. But that isn't really going to look  very real unless you do a lot of work. First, the cloth is not all silk - some is lace which is even less shiny than skin. Second, it needs to be 3-dimensional. Otherwise it will look like body paint.

Then to combine, you run a Blender into Alternate_Specular to choose which specular to use.

A line from the movie Untouchables comes to mind - What are you prepared to do?

I like that word - prepared. It applies to you here. It is about what you're willing to do, as well as what you're able to do. You have to learn a lot more than how to use a Blender.

A texture like this, allways needs a very good displacement map to give it its thickness; to get "life" in the cloth. Without a displacement map, it WILL allways look like bad bodypaint.

The mask BB is talking about is to get that silk shine ONLY on the silk cloth.

The skin looks "dull" also, and a blin nodo can help with that too.

Read BB's post very carefully.

Or send the origional cloth texture, and I"ll see what I can do tonight.

Content Advisory! Language advisory.

Never give up on a good idea,

From time to time, BB can be "hard" in his answers. 8-(

That is just his way to push us all into a better understanding of the material room, and produce a finer quality output.

He rightfully kicked my "ass" in the right direction, more then once :-) :-) :-)

Nothing to do with him being hard or not. I really should just learn what stuff does before I attempt to use it.

Serpentine, don't give up. We all started somewhere, nobody here was born knowing. What I suggest to you, though, is that you put this project aside for just a bit, and experiment with the shader options.

The material room is something AMAZING, I adore it with a passion, and that because I'm a terrible mathmatician (knowing good math helps a lot in making good shaders). Were I any good with numbers, I'd probably be shrieking in happiness all the time when working with materials ;) there's so much you can do, such detail.

Let's focus on the shine. Your Specular Value is set to zero and that would be fine if you had something plugged into Alternate Specular... As it's both Value zero and nothing in alternate, there's no way to have something shine in your shader. The purpose of putting a mask in Specular is to separate what should be the specular/shine in each part, but also if you don't want your skin to shine at all (skin does shine, but softly; I'd rather have no specular in skin than bad specular, and as you're starting in material room...), then black specular = no specular. You can use your mask to define that there's no specular in the skin part, and plug any "shine node" to the part of the Blender node that defines your white.

 

In that shader setting image you sent... Change Specular Value to 1, Unplug the texture from Input_2 (white) in your Blender_2 node (the one that's plugged to Specular_Color). Plug an Anisotropic node to your Input_2 in Blender_2. Render. Let's see. (You might want to change the Specular_Color to white without removing the node connected to it)

A big chunk of the problem is that you have to train yourself to think your way through Poser's labyrinthine node structure. You have to work methodically and patiently or you will get completely lost.

Every time I have to go into the material room I scream inside because I know I'm going to have to construct a bewildering jumble of nodes to do something quite simple. And if I want to do something complicated.... aaarrggh!

My dearest wish for the next version of Poser is that they've done something wonderful with this so that you could, for instance, package up a group of nodes that perform some useful function, hide all the spaghetti inside and just leave inputs and outputs 'open' ready to have textures, other nodes etc. plugged into them. If there were specific parameters inside that you were likely to change, it would be nice to be able to wire them up to controls - which you could label - on the outside of the box. It would be great to be able to save these and drag them into place from a library or call them up from a custom menu.

I can dream...

Ok, so here is what I learnt.. just to show I am actually interested in learning this stuff. OK so a blender node is used to blend two textures together and a transparency map is used to hide bits of one texture that you don't want to see. 

So as I understand it, with the transparency map I am hiding the skin parts of the texture so that what I do only effects the silk bit? 

Now I have seen how to make lips shiny but that effects the whole area. I just took the advice and I changed the node from the blender node and added a anistropic one, but again this has changed the color of the torso if you notice in the picture.

Or maybe a node for screaming in frustration LOL This material room that everyone is speaking so highly of, right now I hate it LMAO Going to take a quick step back before I get a migrane
