Hello people, I've should have post it before but due due to some problems I hadn't much time, so today I did it as fast as I could, just hope it not to be so bad.
I think it would be a little presumptuous to call it tutorial, I just want to tell you the way I do this, I know that most of the poeple that use Poser 5 or 6 by now allready know how to use the cloth room, but maybe some tip or a single step may be usefull.
This first part is about converting dynamic clothes from other characters to Posette (of course it can work with other characters) next (hope time and my job let me do it soon) I'll tell you how I model some clothes for dynamic; and last, when I figure the easyest way, how to tourn these clothes into conforming.
Ok lets go

01

1 - Load Posette and deselect all inverse kinematics.
2 - select any Posette body part an go to window/Joint Editor
3 - Press Zero Figure

02

1 - Load the dinamic dress, I'm usig Juddy evening dress here.
2 - select the dress and go to Object/Change Parent... and make the parent for the dress the universe.

03
1 - Now as Juddy is bigger than Posette we need to scale the dress down in x and z axis to fit better her.

04

1 - Scale Posette body in x axis to 75% and z to 50% or as necesary as to not to see any poke thru, and translate her in z axis if necesary.

05

1 - Now move the animation slider to frame 3 (something betweent 3 and 5 will work but the smalest the frame number the best)
2 - With Posette body selected click on the small little arrow at the top right of the dials window and click on Restore

06 07 08  

1 - Let's move to the Cloth Room
2 - Create a new simulation
3 - Be shure to set 3 (on your selected frame length) as end frame
4 - check cloth self-collision, and press OK
5 - click on clothify
6 - select the dress and press clothify
7 - Press on Collide Against...
8 - in Current Collision Object Select Posette
9 - Unselect Start draping from zero pose and select Ignore head hand and feet (if your dress afect any if this body part then don unselect) press OK

09

1 - click on New Dynamic Group...
2 - click on Remove all and then click on Add all.

10

1 - click on calculate Simulation...
2 - after a moment you shoud end with a beautifully fited dress on Posette

11

1 - Now let's save our new dynamic dress, allways in frame 3 export the dress as wavefront .obj and in the export options unselect everything
2 - start a new Poser document and load Posette again

12

1 - import your exported obj dress and unselect everything in the import options
2 - parent the dress to Posette body
3 - move now to frame 30 (or more, depending on how complex is you pose) and aply your desired pose
4 - repeat the step 06-07-08  

13

1 - Now click on Edit Constrained Group... we don't want the dress to fall down, we will tell the simulator where the dress will adjust to the body so it will not fall to Posette feets.
2 - carefully move your view and select the area that will adjust to the body, rotate the view and make yourself shure the vertex all around are selected, close the group editor
3 - Now this would be a good idea to save the dress, go to the Pose room and save the dress as a prop in a new folder.
4 - go back to your Cloth room and run your simulation.

This is what I've got. No postwork in this picture, just a little play with the material room, textures for Nea and hair. this was the base for my last post in the album.

Just some recomendations:

Don't get scared with the Dynamic Controls to get the fabric you want. I've found that most of the times just Fold Resistance, Shear Resistance, Stretch Resistance and Cloth Density are the most important controls and are self explained, just start experimenting with this values and if you think it's necesary just try the others, by now I allways got the results I wanted without not even considering them.
Allways select Smooth Poligons in the render setings, it will make your dress to look much, well, smooth   .
Hope it's been useful for somebody, if you have some question please ask, cloth room is a wonderful feature of Poser and most of the time not even considered because there is the false belief it's complex and slow, I've used it in my old AMD Duron 700 MHZ and never had to wait that much.
Next I'll try to show you how I model some clothes using all free aplications like wings3d and UVmaper, believe me it's much easyer of what you may think, and the result are very satisfactory.

Excellent work, rayera!

This will help me greatly, as I have barely explored the cloth room
