Subject: My Odyssey Keeps Going On. (Rendering Poser Figures with Unbiased Renderer)

Okay, my story is that I want to achieve to Render a Poser/Daz figure on Indigo Renderer. Its been an Odyssey all the way through (3 weeks) but I have finally managed to get the Poser Scene on Indigo and actually render it. (I have Cinema4d and have had to use InterPoser and Cindigo) the thing is that I would like to find someone that has actually managed to do a Poser Scene Render with Indigo (or some other unbiased Renderer) so he or she could maybe help me. The Indigo Render actually looks awesome, even though my Poser characters looks as if she has some kind of horrible disease. I dont know why, when I send the Cinema scene/Poser Scene to Indigo, the eyes, eyelashes and the hair tips appear white. ((This is something that happens with any character on every particular scene I render with indigo because of its Material Convertion thing, before that, when I render on Cinema4d without the Indigo materials, everything looks good so this happens AFTER converting the materials))

I decided to create the thread on the Poser forums because I think someone who knows about the Poser textures can help me on this one and it didnt seem right creating it on the Cinema4D forums.

The eyes and hair textures from Poser/Daz models seem to have something which makes them not render like they are supposed when converted into indigo materials because, as you can see, everything else renders perfectly. I would like to know what posibilities are there to fix this. Someone told me that this problem could be solved by fliping the alpha channels, but he who told me that has never used Indigo, he told me that because that was what he did on VRay. Anyway, if that is something that is posible on Indigo, I have no idea how could I achieve to do that.
Ive noticed there isnt much on how to use corectly the Indigo Materials around the net, no tutorials and this is my first unbiased render so I kinda need an extra help than just a manual and reading words; most of it on the manual, I dont understand, I may need something like a video or a step by step walkthrough but there is absolutely no such thing on what im trying to achieve on the Internet.
B.T.W, I cant ask anything of this on indigorenderer.com becuase the website seems unatended or something sooo I cant register and make threads on their forums plus they do not answer the "support" emails u send them.

Im asking for someone who has Renderered a Poser Scene or figure with an unbiased Renderer to please help me. I imagine it must be the same thing with most of em. How can I fix this or do this correctly so I can manage to make those beautiful renders I have so much dreamed of for three weeks now.
Any help will be very much appreciated.

if you check the Reality thread in the Forum, there is currently a talented trio creating a Poser to Luxrender exporter.

the eventual aim is to expand to other render engines, but Lux is the first target.

Okay, ill check that out. That could be of some help and it must be something similar to rendering with indigo with cinema as an exporter. Thanks.
It would be awesome if you could post the link but, anyway, ill search for it. Thanks again.

The problem appear to be with transparencies. The material that has the transparency must have specular value = 0. You cannot allow the material to reflect light because it will reflect light from the whole mesh ignoring the transparency map.
Probably you are using the wrong material or wrong setting. The transparency map must be for deciding what is transparent on a polygon and what shows the color and texture of the polygon.

Stupidity also evolves!

The materials for eye brow and lashes and hair are always manually done in the apps I export as OBJ into.  I model my own eyeballs though.

There should be an AI that knows you are doing this during OBJ import and suggests doing it for you.

Sorry, I dont know that. What do u mean that they are always manually done in the apps? How do you do that?

Looks like an alpha layer issue.
Convert the materials before exporting, this will replace the Cinema4D materials with Indigo materials and allow you to edit them. Invert the alpha map in the Blend channel.

First you have to find the transmap image JPG files for the eyelashes and eyebrows that your figure used in Poser or whatever.  Then in your rendering program, you assign your color (usually dark brown or black even) to the eyelash and brow objects.  Then tell your renderer that these objects are using transparency values dependent on alpha maps (trans maps) that you will apply to the UV maps of the eyebrow and lash objects.  Invert the B/W images if needed depending if your app's transparency goes by 100% white or by 100% black.  Turn off any shine or glow that your app may have assigned to these objects.

Here's a sample lash trans map.

Yea, I do convert the materials, that is when the problem starts. Before I convert them, if I render with Cinema, the model will look how she is supposed to. Then, I convert the materials and Render again, her eyes then turn white on the Render (still on Cinema). I First thought this was normal but when I export all, whitout changing or editing the indigo materials, the model on Indigo appeared how she looks on the picture, white hair tips, white eyelashes and her eyes where also white like on the Cinema render.
I will try this inverting the alpha map on the Blend Channel.

I will definatetly try this. I'll see if I can manage to do it. Appreciate it.

Once in a blue moon I have to flip the normals of my lashes if they don't show in a render.  In modo, I'll sometimes make the polygons for the lashes double-sided.

Problem may be: Poser is using "transparency" and means "alpha". Other render-engines may make a difference here. Especially unbiased render-engines because of trying to simulate a typical transparency-behaviour (refraction and other things). Alpha means "not there".  This is different.

Importing a figure with Interposer to C4D may convert transparency to alpha.

Poser materials for lashes often have a bump-map. Delete this.




Kros2692 ( ) posted Fri, 20 August 2010 at 2:21 AM

Ive spent so much hours tweaking the alpha, tranparecy and specular settings and nothing. Ive tried so many different ways. Sometimes it gets worse, other times other white spots appear on the top of her hair but some of the old ones on the tips dissapear. The thing is that is not a "nod" thing like I imagined ir idk, there are just four buttons- Invert, Soft, Image Alpha, and Premultiplied- on the Aplha Settings (Settings of the materials before materials being converted into indigo materials because if I tweak too much the materials after being converted, an error appears when I press "Render with Indigo".) Its getting really frustrating being so near to finally do my renders but not being able to do so because of some stupid white spots.

1st Render on Cinema 4d. Nothing has been changed, just used Interposer to import the scene from Poser to Cinema.

2nd Render still on Cinema 4d. This is after converting the original materials to indigo materials. Most of them turn into "Phong" type. Eyes start to appear white and the hair seems more "blocky", instead of having thin hair strips on the tips.

3rd Render, this time on Indigo Render. This is after exporting IGS to indigo. The blocky parts od the hair appear white, which are supposed to be transparent. Some other hair strips appear white too plus the eyelashes. The eyes are still white like the Cinema render.

I've never used Indigo, but I've seen a similar problem with Kerkythea. Does your figure have some kind of outer eye material (cornea?). When I used PoseRay to export  a Maya Doll figure to Kerkythea, I got the glazed eye effect. Changing the setting of the outer eye material fixed it. I have no idea what the corresponding changes would be for you or even if it's the same problem.

There was also a similar problem with imported Poser hair though I think now with PoseRay it is much better. I'll include a link to some techniques folks used to fix it but since Indigo and Kerkythea are two entirely different renderers, I'm doubtful if it will help.

I've only used the unbiased modes of Kerkythea once or twice. It's just too slow on my ancient hardware.  I was curious though so I loaded an old .pz3 and hit render - and waited...  I didn't notice the shadow on the backdrop until it was done, but after  hours rendering (in MLT mode), I wasn't about to redo it. I'll stick to Vue. The LuxPose plugin mentioned looks very promising. If Lux delivers on their GPU accelerated rendering, speeds may actually become tolerable.

I do have cornea on my figure but I dont think there are reflectance settings. Yea, I pretty much think its the same problem only that settings are a bit different. Im gonna keep looking up for something like that then. Thanks for the help.
The hair thing too, settings seem to be different but im positive its the same problem, just that they are different softwares and unfortunately, im a noob using both cinema 4d and indigo so I dont know how to change those settings or even if im able to with indigo materials. Atleast I have indigo for free for now. It got to my mind to try VRay for maybe better results thinking maybe this was an indigo problem but I just figured out it is something that could happen with other renderers too.
Thanks again.

This is the render on Poser 8.

Attached Link: V4 in Indigo via Blender

Yeah, without specific knowledge of Indigo, it's going to be hit or miss. You might have better luck going Poser->Blender->Indigo. I'm guessing there are probably more Blender/Poser folks using Indigo than C4D users.

If you want unbiased rendering, Kerkythea via PoseRay is good if you can live with basic Poser material export. The Kerkythea forum is pretty helpful. Tne Poser->Lux plugin may ultimately be the best option.

Really though, if you learn C4D, you may find that you don't need anything else. Unbiased rendering is no magic bullet IMO. While it's tempting to jump around, sticking with one application and learning it well will probably yield better results in the long run.

Hi
Question for Kros.
Do you have the Advanced render Module
for C4D??

Nope, my most advanced render is the Poser one.

ps. Im thinking on getting VRay since there is more info on the net about this connection, even the Poser + Cinema + VRay connection so I know its posible to do. Atleast Indigo is free but its been too much of an ordeal to get what I wanted so im giving up.


wolf359 ( ) posted Sun, 22 August 2010 at 11:47 AM

Hi I understand.
We Have C4D R11 with Vray
Advanced Render 3 (rarely used)
and Maxwell 1.7.
and of course have played with LUX

if you can afford it the obvious choice for speed and Hi Quality is Vray as it has a pretty decent material Converter for you C4D scenes
and Vray is a Hybrid engine that can be set to "unbiased" but that is rarely necessary IMHO.

You Might want to consider getting the free version of DAZ studio
which will open your poser scenes natively and using the imminent
[**DAZ TO LUX

**](http://vimeo.com/13547302) plugin due next week.

or you can wait for the possible poser to LUX plugin being developed as we speak.
