I really need to get my latest render off my iriver, it uses dynamic hair, and it looks extremely realistic. Fingers crossed I can find somewhere that sells the iriver cable (why do they insist on using a proprietary cable!?!)

Someone needs to make you an easily accessible bagginsbill FAQ that you can link to in such cases. The trouble with these threads is that it's very hard to find a particular bit of information.

Or, you know, more LOLcats. LOLcats make everything better.

 I'd be willing to contribute to a user manual. After understanding the baic math and how to setup VSS, I've started to understand not just vss, but good 3d lighting, how to mathematically predict and plan out shaders, how lighting affects those shaders, and how to combine all those into doing a composition without postwork.


odf ( ) posted Thu, 16 April 2009 at 10:02 PM

There's the VSS manual by DigitalDreamer, which is very helpful. I'm sure if someone took it upon themselves to keep it updated, many a Poserite would be extremely grateful.

this is true. sometimes BB already answered my question. i forgot it so i am afraid to ask again because i really can not find it in this thread. its waaaay to many pages. i already have 10 links bookmarked from BB. i can not have them all.
there are a lot of good sites that give you free information and knowledge. in the corner you have a donation link where you can give them money to support their sites and their work. i think something like this could BB have. we would support him.

should we make an official bagginsbill thread where we can talk to him about everything? from hair,skin,reflection. not VSS because we already have a thread for this. should we? 


bagginsbill ( ) posted Fri, 17 April 2009 at 5:51 AM

We have a forum for that. It's called the Node Cult at RDNA.

Really, that's why the forum was made. What you guys are saying right now, I could show you the same conversation at RDNA Poser forum.

Somehow it isn't recognized for its purpose by people here. You want to know about shaders? That entire forum is a book about shaders. Nothing else. Not one topic. And I'm talking in almost every one.

The only problem was it had a bad search engine, but I imagine that is fixed now with the new RDNA site.

i must say the forum looks now better and more normal .

*The only problem was it had a bad search engine, but I imagine that is fixed now with the new RDNA site.

*It isn't (yet, I hope) As soon as RDNA was back on air, I tried to find about Oliver's hair shader, but it didn't find anything.

Considering dynamic hair, I really love it, but only with a dark shader like brown or black hair, but blond hair really sucks. I think the problem is that most blond hair shaders use the translucent  setting of the Poser-surface shader. But translucency doesn't work with ray tracing (as BB has showed us many threads ago), so you get light hair, where it's supposed to be dark (in shadows) I've did some experients with layered hair and giving the more inside layers lesser translucency than the outer layers, which gave some more or less satisfying results, but this is just a trick to mimic what it is supposed to be.

What sort of lighting did you use for that render? It looks like HDRI IBL, but I haven't seen many Poser renders that mimicked outdoor lighting as well as you achieved there, even with HDRI IBL.

LOL, it took 2 hours to render, at that resolution. Half the reason default hair takes so long to render is due to the material placed on it by default. the FIRST thing I do is remove that hair node and build up my own hair shader. that thing is a CPU killer

as to the question about lighting, I used GI for this scene.

the GI sphere (read hi res sphere) was blue-grey on the bottom (road) and pale blue on the top (using a color ramp and the v variable), with a single point light giving off an extremely pale blue/almost white light at 80%

I love this skin shader

that single node is kinda like having 2 color ramps, translucence, anistropic lighting and some kindof calculation that makes it opaque in shadows. its the last part that makes it really slow, even if you dont tick the option.

plus it look terrible

 Hey BB, just wondering about some settings. I just used VSS on some tattoo skin and it fades out the vibrance of the texture. Im not really sure where to adjust it so the 'strength' of the texture is full ?



LaurieA ( ) posted Tue, 21 April 2009 at 4:27 PM

I've got an LCD screen and that skin looks AWESOME from here. Is that a Poser or DS render???? If it is, I'm amazed. But I don't have Poser 7 yet, so maybe I WILL be amazed?

Looks fantastic.

if we use the eye white shader then we get this little SSS on the edges. but when the eye is in the shadow where there no specular is then the eye looks to red.

can we somehow make the shader that when specular is strong in the middle there is blue and on the edge red. but when the specular gets lower the eye gets more blue? 

less specular more blue? 


ice-boy ( ) posted Thu, 23 April 2009 at 2:55 PM · edited Thu, 23 April 2009 at 3:07 PM

i was thinking maybe using your SSS from the skin shader and combine it with theGC reflection shader that you showed ? 


kobaltkween ( ) posted Thu, 23 April 2009 at 3:54 PM

why is the SSS on your eye red?  i'd think it would at least be (off) white, or even the same as the diffuse map.



ice-boy ( ) posted Thu, 23 April 2009 at 4:38 PM

the red on the diffuse image is from the veins.

is the eye in the shadows not red?

eyes are absorbing the light inside. they have subsurface scattering.


kobaltkween ( ) posted Thu, 23 April 2009 at 4:45 PM

first, no, the eyes in the shadows are not red.

yes, they have SSS.  so does milk.  neither have red SSS.  you could probably get away with red SSS where the veins are, because red SSS comes from blood.  but in the eye white,  there's whitish SSS.



ice-boy ( ) posted Thu, 23 April 2009 at 4:46 PM

how would you do it?


kobaltkween ( ) posted Thu, 23 April 2009 at 4:56 PM · edited Thu, 23 April 2009 at 4:56 PM

assuming no color correction? i'd pull my SSS color from the color map.  i doubt it would be accurate, but it would be much more accurate than a flat or random color. that way i'd get red where the eye was red, and off-white where it was off-white.  if i were bagginsbill, i'd probably have different SSS workings for the different areas, because i'm betting the sclera has very different SSS values than the sort of fleshy stuff around it and connected to it.  i've seen maps for eyes where the back and edge area were obviously supposed to be very fleshy, and i'm guessing those should have a different treatment.

and just as  by the way, skin doesn't have red SSS either.  it has  a combination of yellow, waxy dermal SSS and red subdermal SSS.  since we don't have layers in Poser, the best way to deal with this is use orange.  i personally do something kind of crazy and complex to drive the hue with the original diffuse map with the SSS burned in.  it works pretty well for me, most of the time.



kfox ( ) posted Thu, 23 April 2009 at 10:55 PM

Hi - all of a sudden VSS is not applying on top of the texture, but replacing it. Any suggestion on where to start looking? Seems to work fine on M4, but not V3/M3. I'm using Poser 7 on a PC.


hborre ( ) posted Thu, 23 April 2009 at 11:06 PM

Works fine with every model I render.  Are you applying a third party texture first?

...there's a pretty good coverage of the GC topic as well (see link).  There are example images  in there that look like tons of images you can find in the Poser galleries (various problems related to non-GC, resulting in either too dark or attempts to 'fix' that by simply increasing the lighting levels, etc) - but more to the point is.. a good explanation of 'why' GC is needed.

Another interesting thing from nVIDIA is that their recent drivers (185.xx series) under Vista now offer realtime AO to any app/game that wants to use it:

Realtime AO

Right now it adds a large performance hit, but looks pretty neat and is still much faster then anything we can render in our various 3d apps. IMO they really should consider supporting it in the next Poser versions.

A bit OT, but I also find it interesting that Direct3D 11 is adding the capability to basically do the same type of Polygon Smoothing that the FireFly engine (Reyes renderer) does - but directly in hardware by the gfx card (ie. breaking triangles up into mini-bezier patches).

(read down to where they start talking about PN Triangles - this is effectively what Poser does)

I have a problem with the Pr3 skinshaderprop:

I want to make a suntan shader for the chest, nipple and hip area.
I made a new materialzone: Template suntan, and attached the torso, the chest, the nipples and the hip rule to this new template in the shader rules. After I synchronised and rendered only the torso and the nipples had the new shader, but the hip-zone didn't.
I noticed that in the shaderrules there's a Asterisk missing after hip, so I made a new rule named hip but it still doesn't work. What am I doing wrong?

best regards,

Bopper.

bagginsbill ( ) posted Fri, 01 May 2009 at 8:25 PM

When more than one wild-card (asterisk) rule matches, VSS uses the one that has more letters in it.

The V4 hip zone is actually not called hip, it is called 2_SkinHip.  Two rules match this: skin and hip.

The rule hip was generic and not specifically for V4 - it picks up other figures that do not use the word "skin" in all the skin zones. Because the V4 figure uses the word "skin" in every skin zone, you need to use a longer, more specific rule.

Try skinhip
