Dynamics for Dusk - Mr Darcy is a dynamic wardrobe, created for Dusk by Dawn. This is Poser dynamic wardrobe; it cannot be used as-is in Daz Studio 3 or 4.0 through 4.10. There are, however, means by which you can drape in Studio 4.0 or higher using the paid VWD Cloth and Hair at Renderosity. If you have the dynamic plugin from Optitex for Studio, the paid DynCreator for DazStudio will take the clothing prop and convert it to something Optitex can work with. Daz Studio 4.11 introduced dForce, with which most Poser dynamic clothing items can be made to work by applying dForce surface settings. Some tweaking may be necessary.
The download includes two tops and two pairs of pants - each pair of models are the same mesh, but have different constraint groups. The download does not include textures.
