My Pants Keep Falling Off!

I created some pants in blender for a figure. I pinned the top verts to hold them up in blender when I ran the cloth simulation and it turned out fine. So I exported the obj and imported it into daz studio. I applied dforce to them and ran the simulation. They just fall right off. How can I fix this issue?

    Did you weight paint the pants onto the character in Daz? That might fix the problem if you haven't yet.

    make your pinning vertices a seperate shading domain and turn the simulation down to zero on that surface

    Well, I see that I have much to learn about Dforce. I have a lot to catch up to altogether. I haven't caught up to weight mapping. Wendy, I assume you mean I should make them a material of their own and somehow turn the simulation down on that material? That's how poser's clothing room worked for me. But not sure about doing that in dforce. Where do I find the option in the simulation?

    in Blender if you make them a separate surface it should import as such

    otherwise you need to use the geometry editor to assign one

    under surfaces there is a slider for simulation, turn that down to zero on the surface you want to not simulate

    You need two surfaces minimal:

    a) a belt / elastic waist - set this up with a set of dForce parameters to cause it to slightly tighten above the hip, but not so tight that the pants waist circumferance is tighter than the model waist and you have poke through.

    b) the rest of the pants will then be suspended like real pants would off the belt / elastic waist line

    Problem is the dForce parameters you need to give will be affected by the surfaces on the pants and the number, location, and sizes of the polygons in the pants. To get the right parameters you need a really fast GPU to do the dForce super fast so that you can try a reasonable amount of dForce parameters until you find a set of parameters that works reasonably well.

    I managed to figure out how to assign the different materials. So I have an elastic waist surface. I also found the simulation settings in the surface editor. But what parameter is it in the simulation settings that could create a tightening?

    Contraction-Expansion below 100, e.g. 90.
