Quote - You raise an interesting question, Anthanasius... gamma correction, as I understood it, applies to images (like ImageMap type images) only, right? You wouldn't gamma-correct a pure node-only shader, would you?

That's an interesting question I never considered. I wonder what the answer is too.

err unless x=0 then x-0 would be 0

x-0 is not 0 it's x agggg!

Quote - Would you like a VSS sRGB skin shader? I could set publish one pretty easily.

please!

oh and I'm quite sure someone said they needed the hair shader.

Thanks cobaltdream! I have enough math knowledge to get by, but I get overwhelmed by the material room. Your putting simply helps in the approach I should have taken from the start.

I have to agree with **RobynsVeil ** a wiki on nodes would be nice. Somewhere where each step is broken down to be simple. Example to add gamma correction do the following, then explain how each node is interacting.

Brilliant dogs, those border collies... we went to the Great Australian Outback Spectacular which for the most part was a bit over the top, but the horses were lovely, and the collie stole the show!

Nope, I am Canadian. I've seen many border collies in action, and they all seem pretty smart. Mine was no exception, she was sharp as a whip. Amazing to see she was never near a farm but instinctively would round things up, other dogs, children and even drunks. I would hazard a guess they would be popular where ever there are range animals. She was great with young kids, super patient, never snapped. She did shed constantly though.

Oh, one thing she never ever learned... To stop chasing skunks. But hey we all have our weaknesses right?

I got my new Nikon D90 SLR. Of course you can take great pictures with a pocket camera, but the odds of doing so in a given amount of time is smaller than with the big, fast SLR. In two days, I've shot over 400 pictures. This is the best one. My dog, Ricky, enjoying one of his Christmas presents.

I've cropped and reduced it for posting in this forum. Click for full size.

oh looks like a dog I used to have (miss her dearly). Is it a cattle collie and border collie mix by chance?

As for subtracting a mid gray, I think it's used when the bump or displacement map was made for a program where mid gray would be level. The subtract mid gray function is just to make the map poser friendly.

Though if you ever find the complete cheat sheet for nodes, I love to read it too.

I did expand on the handling of SSS in this version, as well as ordinary diffuse and specular and other effects. Everything here is based on the principles of layered interactions. I start with a certain percentage of incoming energy available for specular interactions. As the energy is consumed by those in some areas, there is less to reach deeper for diffuse reactions, or SSS reactions. So by building the material response in layers, instead of just adding a bunch of independent effects together, I get a lot more realism. This is to be expected, since it is what happens in real life.

And this bit of simple logic or otherwise put genius, is why I am now addicted to these shaders. I can't imagine not using this on any render now. Heck I even tend to add parts of  this to stuff that is not even human skin just because it looks so much more realistic. I wish I could follow your logic better, I'd have it on every surface wood, stone, water etc.

The scripts are there, they just look like broken images (due to a sloppy data transfer process when the forums were converted from EZ to PHP).
Right clicking and saving the file with a PY extension is all you need to do.

Thanks these will come in so handy.

Couple quick questions,

Can VSS work with props? I read the read me, the pdf, but I don't seem to understand how to get it to work on props with multiple material zones.

After using the default skin shaders and falling in love with them, I have one little problem, when using props and figures that are not people, I have to tone down the lighting to get the look for the skin, then everything becomes too dark. I have tried coping the shader tree from a figure to the props and changing texture and bump maps, but this isn't quite right obviously. Is there a simple way to figure out what to change for say rock or wood to get it too look as good as the skin, and still be correctly lit?

um, not to say VSS is a shader, or thats the only thing the skin shader does.. I think I better just go back into the shadows now.

Edit: first time posting, posted nothing at first

cherokee69, are you by chance using lights with AO on them? This was what I was doing at first, and I don't think you are supposed to use a light with AO, rather this is a work around to create AO with out AO lights. I could be wrong, if I am, I'm sure someone will correct me.
