Here is how to get a Poser file into Blender. Start by importing the file into DAZ Studio.
Select File > Import
and navigate to the Poser file (.cr2, .pz2, ...). Repeat this step to add clothes, hair, etc.
Apparently the clothes fitting is not perfect.
We
could save the character as a DAZ file now, but then we would not be
able to pose her in Blender, because Poser figures are skinned with
envelopes whereas the DAZ importer only handles vertex groups.
Fortunately, we can convert to vertex groups in DAZ Studio.
Select Figure > Rigging > Convert Figure to Weight Mapping.
We
get to choose between TriAx and General Weight Mapping. This choice is
not terribly important, because TriAx will be converted to general
weights in Blender anyway, but General is probably the best choice.
here.
This step has to be repeated for every figure in the scene, i.e. for each piece of clothing.
Finally
we export the final world-space coordinates to a .json file using the
basic data exporter that comes with the DAZ importer. See the blog post
on JSON fitting for details.
Now
we can import the Poser character just as any other DAZ file. In my
example there were a lot of extra nodes that correspond to empties in
Blender, but it is easy to get rid of those. Just select the empties by
type and delete them.
