Design Issues Affecting VF Garment Simulations in Poser
While testing Virtual Fashion garments with Poser, we discovered that certain design choices may either cause very slow simulations or fail simulations altogether. These are the two areas where such problems may occur:
• Narrow strips of fabrics
Some design elements such as bands, straps or sashes may result in an unevenly distributed mesh when exported from Virtual Fashion, and as a result may affect the cloth simulator performance and render results in Poser. Specifically, the Poser cloth simulation may in some cases be degraded, and render results may show shadow artifacts. These effects may occur when straps or bands are created in Virtual Fashion by mirroring and duplicating cuts using the Cutter options. The shoulder straps in the following figure are an example of straps created by mirroring and duplicating an original curved cut.
The resulting mesh may include polygons that appear to be elongated or bunched together, as shown in the following image. When converting such a garment to dynamic cloth, in some cases the cloth simulation performance may be markedly slow or may terminate. In order to improve simulation performance in such cases, the straps can be removed or “constrained” from the cloth simulation.

When I constrain the staps on my Little black Dress they float above the shoulders when I don't they fall through the shoulders at the contact point.

Ok this is getting really frustrating, VF is really simple to get the hang of, if you can't get to grips with modelling like me then this gives you a whole new approach. You really can make a simple little black dress in about ten minutes. THEN you try and run your sim in Poser and everything gets weird. Either the sim hangs or takes so long thet I cancel. Then you finally hit one that takes about fifteen to twenty minutes so you stick with it and at the end you find these long poly threads like Mizrael's pic of the pants. So is this a bug? Or does someone know something that I might be doing wrong. So for I guess it's more failures than success and that's a shame because I'm loving having a way to make the clothing that I want. I would also like to hear from other users.

Unfortunately it becomes apparent after you buy Basic that most of those gallery items on show at EF were created with another version. On the plus side it is extremely easy to use and get the hang of. On the minus side once you are back in Poser is when you'll discover issues with the garments you've created. Ultimately I think you need to combine VF Basic with a modelling program to get  the best results. I use dynamic clothing often so I'm used to how long sims take to run but with 2 out of 3 items I've made so far I just gave up, when it takes more than 5 or 10 minutes and hasn't started the first frame then you get the feeling somethings wrong. My system isn't the problem, I'm running an  AMD X2 4200, 3gig RAM, GF 7800 card. Finally when you watch the videos at EF and look at the gallery pics, take it with a very large grain of salt.

AS I started this thread it's only fair to point out that my problems were partly my own fault. I don't know how part of my street address became my city but I should have spotted it when I checked my profile. Rylan (krazik) was extremely helpful and I have also recieved follow up e-mails from Mary Tobias. I'll now take this opportunity to to thank the CP team. Thank You CP team.

I just finished the download which is why I dissapered for a couple of hours. Ave is part of my street address and shouldn't show as my city. Your're right though, I just modified my profile thanks for pointing it out. Hopefully this will solve any future problems.

Incredible I sent my username to Rylan and within 5 min I recieved an e-mail telling me my order is available. Thank you Rylan, thank you.

I just found the other thread regarding the same problem 'Is CP on strike' so I'm definitely not alone on this.

So do I, the free items aren't a problem just my purchases.
