Thank you for all the suggestions, I feel more confident about this now than I had. I'll post any noteworthy results I obtain.

That looks pretty good.
Only thing I know of would be the golden ratio. Not sure how well that would work for a banner, though.

Here's a close-up. The part could be a bit more defined, and (for close-ups like this, at least) more verts wouldn't hurt here and there. Even at highest settings, the hair proves difficult for anti-aliasing. I'm not sure what the dark bands are across some areas.

As it turns out, I don't have enough memory to even finish pre-calculating the light for 140,000 strands, let alone render it (for now, at least). So I toned it down to around 70,000-80,000 hairs, and rendered with global illumination enabled. I still couldn't get that one group of hair in the back to change color. You can still see the outline of the head through the hair; I'll have to check to see if there's transparency applied to the hairs, otherwise I'll either try adding more density to those areas or making the strands themselves thicker.

Here's a side-lit shot. Again, not very high settings, and with 100% intensity in the SSS channel, she looks a bit waxy. Also, eyebrows and make-up areas on the texture have been adversely affected, and the interior of the nostrils should be darker. Perhaps I will try excluding them from the SSS.

I spent part of the day trying new settings. Unfortunately, it isn't quite as simple as "make her bigger."

Most of my tests had translucency (inside the SSS controls) set to 50%, but taking it down to 2% actually gave me better lighting through the ears. I don't understand why.

All of my previous images with SSS have had intensity set to about 25-30 percent, but in order to get realistic results I believe this needs to be much higher, so it's at 100% in these images. Without changing SSS color, though, you end up with a character that looks like a giant fetus, so to equalize this I've used a considerably darker color than before (on the HLS Wheel it's H: 99.68%, L: 14.99%, S: 29.99%.)

Perhaps this is too high, maybe 70% - 80% would suffice. I still haven't been able to achieve a blood red color within the ear, and am running out of settings to change. If I make the SSS color redder to get red ears, the whole skin is affected. If I correct this, the ears are no longer red (I realize not every shot of a cg character is going to be realistic with red ears, but I'd prefer to know that if a light is in the right place and bright enough, my shading is going to be fairly accurate and will produce good results.)

Of course this is partly due to the fact that I'm trying to give less-than-paper-thin surfaces the appearance of mass and volume. Perhaps my only option is modeling an interior mass for the ears, and possibly the rest of the body, and assigning it a seperate shader.

I don't know for sure if the method will transfer over to my usual skin shader, but I have reasonable expectations. If I had to guess why it worked, I would say it has something to do with how Carrara calculates the light. Before I changed the figure's size, her head was only a few inches in diameter. You could imagine the light waves (or particles, depending on how you look at it), whose size you cannot manipulate, as being much too big for her to look realistic. It wasn't until I brought Vic up to human proportions that she was in scale with the light in the scene. Does that make sense?

I spent several hours trying many different variations inside the SSS channel, and couldn't get anything to look good. Then, before turning off the computer, I decided to scale V3 up 1,000 % (Making her a little over 10 feet tall). This made all the difference. The first image shows her with the default wax material applied to the face and scalp, and only approx. 13" tall. A small spotlight is directly behind the ear. The second is her resized, with the spotlight sized the same. She clearly appears much more organic, with thickness variation apparent within the ear, exactly as I wanted. Image three is the same, only I increased the size of the light to cover more of the head. Thank you Mark and bwtr for your input, it's much appreciated as always. It's funny how simple the answer can sometimes be.

Hair color changed and noise taken out of the shader altogether. I couldn't get the back hair group to be the same as the rest, even though I did change the color. Odd. Perhaps the number of verts per hair should be increased a bit, as it is noticeable in certain areas. I'm not sure if there's a way to edit the hair shader in Carrara. Currently, everything in the texture room is black. Next image, if memory holds out, 140,000 strands.

Trying out one of the V3 hairstyles by Adorana, default everything. The dark hair color makes it hard to make out details, but right away we can see that the hair needs to be much thicker. Right now she's only at about 14,000 strands, if I remember correctly.

Thanks guys. I do recall looking into the Anything Grows plug-in; very attractive, especially at the price. I may end up getting it, along with a few other things, later on. Next test, one of the stock dynamic hair presets for James. I increased the total number of hairs to about 80,000. I also applied a skull cap, but the texture on it doesn't match the hair color at all. Looking up numbers on the web, I found out blondes have an average of 140,000 hairs on the scalp, brunettes have around 110,000, and redheads have the least, only around 87,000. http://img.photobucket.com/albums/v141/TerraMatrix/4-1.jpg http://img.photobucket.com/albums/v141/TerraMatrix/5-1.jpg Having said that, I suppose his hair could be a little fuller, at least in the front. The shading also looks a bit odd, almost... I don't know, metallic? I know there's noise thrown into the shading automatically in Poser, I'll try messing around with that, maybe taking it out completely. The hair also intersects itself at certain points, running a dynamic simulation to let it settle into place first would solve this. One thing that concerns me is getting realistic shadows. At this point I see a lot of crappy shadow artifacts along the edges. How can I fix this without using unnecessarily high settings?

At this point, I thought back to Poser's hair room. I stopped using it long ago, as it was always such a witch to render with. But, knowing the speed and quality Carrara delivers, I decided to give importing a Poser file a try. I applied just over 110,000 hairs to a sphere, changed the number of verts per hair from 20 to 10, tweaked the root, tip, and highlight colors, and brought the file into C5. I actually used somewhat higher settings than I did with the previous test, and still the renders finished in under half an hour, (under 20 minutes for the second two shots here). There were not enough hairs to completely cover the sphere, but changing the ball's color from the default gray to a dark blue helped tremendously.

Here's the alpha (resized) that I used. With 19 strands, and 5,000 replications, this equates to around 95,000 blades, although you're obviously only looking at about half that.
