I work with Poser too, but my version is way newer than P6 ;)

If you still use P6 I would give DAZ 4 a try. 

DAZ Studio Pro 4.5 is free to download at the DAZ-3D homepage!!!

New furniture, new shaders,... :-D

Ok, back to the problem: I finally solved it, thanks to Bills suggestion with the shadow-min-bias value.
Being not really familiar with Poser my fault was the mesh I imported.
I modelled the cupboard in C4D and in a silly attempt to reduce poly-counts I decided to make the blinds and the floors of the drawers as zero-thickness planes, just with "folded" edges, if you know what I mean.

Like this ____/  intstead of a closed form.

In C4D this worked fine, but in Poser this did not cast a shadow as I wished.

By the way: My units are in mm, but shadow min bias value did not change when I changed to inch.

@RobynsVeil: Diffuse Value was 1, now I changed to 0,9 which is way better, thanks for that!

To the final result shown above:

Left is with IDL using BagginBills EnvSphere with an interior HDR picture, one light from left top, white at 80% intensity. shadows raytraced at strenght 1.0, blur 2.0 and min bias 0.05

Right one is without IDL, envsphere deleted, 2 more lights with same settings but fill-light from left at 60% intensity, top-left-light and back-light at 100%

Well I really have to say I start to like the firefly renderer with IDL :-)

 A lot a thanks to all who helped, I really learned a lot!!!

Ok, more info:

Ambient Color is 100% black, Ambient Value is 0. I only changed Diffuse to white, everything else is default.
All parts are "visible in raytracing" and "cast shadows" set.

Now I have 3 point lights with raytraced shadows,
Blur Radius 2, Samples 19, Min Bias 0,05, AO off, Athmosperic Strength 0,01

Poser Version: Poser Pro 2010

Render settings Firefly:
Cast Shadows On, Raytracing On, Raytrace Bounces 2, Irrad.caching 50, Indirect lighting Off, pixel samples 5 ( tried up to 12), Min Shading rate 0,1 (tried 0,01 too), all the rest is Poser default.

Thanks so far...

Ok, just did so and even on all 3 lights, but no difference.

Also changed the lights to almost face 80° down, so there is absolutely no direct light shining into the drawers, but just looking the same :-(

I'd say one very basic fix would be to check the polygon direction in C4d before exporting.

Therefore got to polygon mode and select all polys (ctrl+a).

Yellow polygons are pointing to you, blue ones away. To rearrange them go to Functions and "arrange normals" (I hope thats the exact name in the engl. version).

This can also be done by hitting [U] then [A].

If this solves the problem, so far so good. If not, it is necessary to get rid of those corner points with so many triangle-polys ending there. Therefore you can cut the outside edges of your model at as many points as you have on the inside hole. Then reconnect these points with the bridge-tool making quadrangles instead of triangles. This is a bit time consumting but gets way better results than these boolean mess. 

thanks for all the explanations!

So far I really get good results at trying dynamic clothes.

Allthough I have a problem:

Is there a way to "pin" of "belt" a certain part of the cloth to a body-part? 

Sorry, don't know how to describe that better, just knwo how it is called in C4D.

example: I have "LittleBlackDressV3" witch is shoulder free, but with arms. Whe I have a pose where V3 has her arms hanging down the dress is simulated to slip down over her breasts and then folding over the abdomen.

I am sure someone of u knows how to avoid that. :-)

@theKageRu: THANKS SO MUCH, U ARE GENIOUS!!!!

I even tried the "import as a whole" way some time ago, but wasn't able to move parts then. I allways tried to make a  figure and rig in poser can drive u crazy for non-organic forms!

Moving the parts in C4D and then imorting the whole object as a morph-target again, thats the point i didn't see.

Now it works perfect!

Thanks to all others too!

Netrunner

Thanks alot pjz99!

I am absolutely new to the new IDL system (just know that from Cinema4D) and after I did what u wrote my render look WAAAYY BETTER!!!

Again thanks for your tipps!

Using magnets is what I try to avoid cause C4D gives alot more morphing options than that.

I now tried exporting as a wavefront obj "as morph target" but now the figure-parts come out zeroed in C4D meaning that my initial poser pose is not transfered to C4D.

I guess thats what they mean when the say "no world transformations"

:-(

Hi arcebus!

Thanks for the site.

I forgot to mention that I am still working with Poser 6 and I am looking for a free solution if possible! :-D

Hi hborre!

The workflow I described is the one that works. If you export the whole figure or one single body part doesn't matter, just a question ov worklow...

What does NOT WORK is as you mentioned to pose V4 first and the export and morph a body part. When it comes back to poser and is set as a morph target the whole part moves "elsewhere" when the dial is set
