I have had this much success with Chanlum using the Poser Plugin and C4DXL7.03

The relevant settings I used are the following:

LUMINANCE:
R329
G152
B122
Brightness: 25%

Chanlum to MULTIPLY100%
Samples 20
InitOff: 0.5
SamRad: 40
SamType: Area
Gaus+Shadow ENABLE

REFLECTION CHANNEL!!
RGB all to 256 (100%)
Brightness: 3%

Change DISPERSION to 25%
(experiment with higher values for shiner areas like lips and fingernails).

SPECIAL Thanks to:
Kaiskai for his support
Everyone who responed to me in the original thread (I forget exactly since some of the posts were lost)
And special thanks to Leigh for her Texturing Lesson 5 which suggested using Blurred Reflections!

OKAY...

SCRATCH the REFLECTION SETTINGS

I have had to re-render it due to an anomoly resulting from too much refletion and not enough diffusion.

The new settings:

REFLECTION at 1%
BLUR Dispersion to 75%

If you can see a reflection in the thigh of the left hand figure, reload the image...

This latest render took: 2 hours 41minutes... it has approximately 300,000 polygons visible in the scene. with transparency mapping on the hair, 20 lights and, of course, all the skin has real reflection and bluring...

Hmm, I hate to tell you this, but to me the skin looks too dull...Or matte. Kinda hard to put a finger on.
I would personally make it shinier myself. I would also recommend mixing it with a good Poser skin texture, since you're already using poser figures.
Here's a link to one I did with Chanlum. Don't know if you saw it already. Apart from some mesh artifacts I was pretty happy with the skin itself.

Keep working on it. Chanlum is a bitch to get just right and I am still trying myself.

That is a pretty realistic render, but you need to do something with the lighting... perhaps adding a single omni light at 100% strength... either way, considering how realistic of a render you're shooting for... you may want to keep fiddling with the scene a bit.


Good show so far though

TAG, I think you're right, it's the lighting. In spite of it's "flat" appearance I'm using a very high quality texture composite set...

I'm also not using any bump mapping, so when I get that inserted it should make a difference...

The realism I'm going for is only in the skin... btw... these figures are just stock poser figures.

wholly bovine...

Maxon's using the same model I'm using for the above image to promote body paint:

They have a nicer texture, though... That's Daz's Victoria Mesh...

Continuing...

I'm not exactly sure if I'm getting it right still, or if I simply need to use better texture maps. The ones I have are not bad, but they're not the kind of quality that would allow for closeup work.

Here's another render: same figure mesh as the other two:

No reflection on this one... it redners SOO much faster... otherwise the exact same settings... except that I included bump mapping on him, which I don't have in any of the others...

15 minute render.

I'm still looking for critiques and advice... :D

Hmm... where do you get Chanlum? and is it free or does it cost money?

it's free from the Happyship website

I think the best way to see the difference that Chanlum makes is to show with and without the shader active. Do renders of the exact same shot with it and without it. Also, Chanlum works best when mixed with another shader or texture via Fusion in the luminance channel and a texture in the diffusion channel.

Hey sweet, Free is the best :). Now I can finally make the sheets have a clothy feel in my bedroom scene.

(Note to Moderators: I'm posting this here for refference in case anyone asks... :D)

When you bring in a Poser file into Cinema4DXL7.3 everything comes in very well, a credit to both CuriousLabs Plugin and Cinema4DXL7's legendary Solid Code.

C4D will find all textures under RUNTIME/TEXTURES but no others! If you have your textures anywhere else, you'll have to manually load them.

However, to get the most out of it there are a few basics that need to be understood.

TRANSPARENCY MAPS
1. Cinema4DXL7's Transmaps are exactly the opposite of Poser's. You will therefore need to somehow reverse them for use in Cinema.

A. Select your transmaped material and goto the Transparency Channel.
B. Highlight the TEXTURE field and COPY the text.
C. Click on the Arrow next to the texture field and goto bhodiNUT SHADER: COLORIZER
D. Click on the EDIT button (Located in the Texture Box)
E. In that shader dialog: goto the texture field and paste your Texture Filename
F. Below you'll see a colour slider the three boxes below the sliders control colours. Click on the BLACK box and change it to White, click on the RED box and change it to GRAY, click on the YELLOW box and change it to BLACK. HIt the OKAY button! (Do NOT hit anything else BUT the OKAY button, as it will cancel your changes)
G. Your transmap is now reversed, you can copy this channel to each of the other materials and simply paste in the needed map.


2. DEFORMERS
and other stuff you shouldn't see.
Sometimes the deformers will be visible in Cinema. You can correct this by selecting the deformer's material and disable all but the ALPHA CHANNEL. In the alpha channel apply an all white texture and it will dissapear.


4. MULTIPLE PZ3 vs Multiple Figures in a single Pz3
Especially when Animating, I have found it best to break apart Pz3 files with multiple characters embedded and import them into Cinema individually, especially considering materials need adjustment inside Cinema. A C4D with embedded Pz3 can in turn be imported into another C4D file for final rendering.

5. Animation
All animation imports into Cinema4D. Since this is true, very little needs to be said regarding this except two important items.
A. Cinema4D's default frame rate is 30FPS. It is best to change the framerate to MATCH the framerate in your Pz3 file. Poser's default is also 30fps.
B. Cinema4D's default frameset is 90 frames. If your Pz3 frameset is MORE than 90 frames, it is best to increase the C4D file frameset to match before you import your Pz3 file.
C. Poser Animations are NOT embedded in a C4D file, they are linked instead. While all Material changes done in Cinema4D are permanent, all animation changes must be done in Poser. It is important not to have Poser and Cinema4D open at the same time when working on C4D files with Poser files inside. Close Cinema4D, load your Pz3 file, make changes, save and close Poser. Re-open the C4D file and you'll see the changes you made in Poser (all except materials changes, which, again, are permanent inside C4D).
