Hair renders with octane

I've not seen thread started with this so I decided to ask.
As we all know poser is not great for hair renders I'm just wondering if there is any way that we could make within octane hair look more realistic and lifelike.

I'm really not sure where to start with this and what you can recommend.

Maybe some sort of sss but for hair?

The best plug-in I've ever seen for hair is a program called hair farm but unfortunately it's about $700 to buy. And is only available 3-D studio Max

Mesh is fine, the material does not need SSS,it'll just require some glossy material that is all :)
The tricky part & where the hair looks "life-like" or not is mostly the specular/roughness/index part.
Play with it till you get that nice shine on it! because it looks flat at the moment.

Yes, her eyes are great.

Hair is probably the area I've least experimented with. But the shader I'm using at the moment is attached. I'm sure it can be vastly improved on.

Well here's my first attempt at changing some of the settings I'm not sure what i am quite doing to be honest with you as I said in very new to this whole.

Rendering malarkey and I am using a very old GTxs 450 card that takes me for 4 hours roughly to render with hair.

That is such a nice render!!!

Are you missing a diffuse map? (says "diffuse = ").

For me, the reflection in her eyes is a touch high too.

Her skin is absolutely perfect. Nice job.

Maybe I misunderstood about glossy I thought you had to set the tab to glossy and then change the default settings here is my default settings what needs to be change on here to achieve translucent effect on hair and to make it more realistic I probably misunderstood/

Yes you're right guys eyes a bit over glossy overkill but still it looks nice

Well his results with playing with the various settings.

Still not sure what settings to use but I'm sure I'll get there eventually

few changes

Hi Chopper

Maybe I misunderstood about glossy I thought you had to set the tab to glossy and then change the default settings here is my default settings what needs to be change on here to achieve translucent effect on hair and to make it more realistic I probably misunderstood/

From the default converted hair material, try roughness 0.3, filmwidth 1, and I think I used opacity at 0.8 or 0.9. Bump power 1. Then adjust the /amount/ of specular with the specular "color".

Also, in "imager", try gamma at 0.8 and "exposure" 1.2, and adjust the overall look with the "saturation".

Which figure are you using in the render?
Which skin material is that? And is it an SSS shader, or the default converted skin material?
Looks great!

The base figure is Victoria 4.2 from DAZ

With the add-on figure of Paris from danae

http://www.renderosity.com/mod/bcs/inde ... ndor=danae

Is probably the best for realism in the whole poser production

I've been using this stuff about three years no one even comes close

two baseline renders from realism. (I've added no sss whatsoever so far to the skin)

It's a baseline render basically straight out of the box with no tweaks.

Basically it's the default skin shader.

And still l bit confused about the settings sorry about this is I said in very new to this forum
"roughness 0.3, filmwidth 1, and opacity at 0.8 or 0.9. Bump power 1"

The only way I see these settings is converting the default from diffuse to specular. I take it this is correct
Seeing enclose screen dump?

as Default i only see power,gamma,scale,ray_step

You need to set the material to glossy.
There you have a roughness and a film-width channel. Opacity and bump channels are present in all material types.
