The Romantic Dress, like all my products, already features material areas designed for use with groups.

Yes I know that feeling, selecting material groups is not possible anymore with the new cloth room  :-( 

I found a feature that lets you use the material domains created for the dress simulation; I was able to use it to apply a constraint to the skirt's waistband so it stays in place, but I don't think you can add multiple constraints—or, more importantly, apply different values ​​for weight and deformation resistance. I'm currently exploring this aspect, but I'm still figuring things out as I go.

@tipol The reason I added the group for the lowest tier, rather than using the material, was that the material included the bust of the dress and the straps. I only wanted to work with the lower portion. Most of your items that I work with have some nice material zones for working with to adjust the constraints.

maybe it's something i missed, but where did this new clothroom come from?  is it another 3rd party adapted into Poser?  at this point, or some time in the not so distant future, couldn't AI be used for something, well, useful, like generating a truly compatible clothroom that's user friendly and easy to use, and then have AI integrate it into Poser, or tell the few devs left how integrate it?

i'm not one for AI as it is currently being used in so many ways by so many various peoples, but since it's here to stay, why not figure out ways to truly create something with it instead of just using it for sloppy soup purposes, with relatively mindless intent... shrug

this current clothroom just seems like too many hoops to jump through to not even truly reach a decent result... 

it really just seems that Poser users have to 'settle' these days because some-is-better-than-none which is absolutely heartbreaking in many regards, and it's not just the clothroom either... sigh
