Simulations are no longer created during import. Instead the simulation information is stored inside the imported meshes, and can be recreated with the Advanced Setup > Simulations > Make Simulation tool. See the documentation on the Simulation Section
for more information.
Many modern clothes use dForce
which simulates draping and movement of garments in DAZ Studio. The
corresponding feature in Blender is cloth simulation, which has been
considerably improved in Blender 2.90. For some time, Alessandro Padovani has nagged me about including dForce simulations in the DAZ Importer
and finally I got around to do it. Actually, this is not the first time
that I attempted to do this, but the previous attempt was half-baked
and never took off. Thanks to Alessandro's excellent help, this time
things worked out better. We can now import dForce simulations in a
useful way with the development version of the DAZ Importer.
First of all, we need to enable Simulation in the Global Settings
otherwise everything simulation-related will be ignored when the file
is imported. We then proceed to import the DAZ character as usual. This file

the body mesh and open the modifier tab. The body has a new collision
modifier, which means that it will act as a collision object. The
modifier settings are found inside the Physics tab if you need to change
them. The DAZ Importer changes some settings, mainly it increases the
Bardot top has two new modifiers: a cloth modifier and a collision
modifier. We can change the settings of both inside the Physics tab, but
I left the settings unchanged. For some reason, the Bardot skirt did not
receive a collision modifier.
top and skirt also have subsurf modifiers, but the simulation seems to
work better if you delete them. This improved performance from 0.25 fps
to 0.30 fps on my machine, and also made the end result better. Perhaps
this happens because the Bardot skirt is already a high-poly mesh.
simulation parameters can be tweaked in the physics tab. One important
parameter is the pin group, which is deduced from the dynamics strength
parameters in DAZ Studio.

affected by the simulation, the yellow region only slightly.
is a typical frame in the animation. The garments has some interesting
movements, but in my opinion the wrinkles are too extreme. We need to smooth them
we do anything else, we need to bake the simulation. Otherwise it will
be lost as soon as we change anything. So select the top and skirt, and
in the physics tab press Current Cache to Bake (for each garment). The
simulation is now baked.
are several ways that we can smooth the animation. We can e.g. add a
Smooth Corrective modifier after the Cloth modifier. The default values
for the paremeters work well.
Alternatively, we can add a Smooth modifier and change the Repeat value to 5.
Here is the simulation at frame 80, without and with the smoothing modifiers.
