Is it possible to export Poser figures to Blender? Cheers

Yes. The easiest way is to export them as obj files and in the export options pallet, make sure to check the use full texture path so blender will find the textures. It doesn't do bad with that if the textures are simple. The object will import very tiny so you may want to scale it up.

You can also use fbx if you want to do animations, but I've yet to figure out the export/import settings so it doesn't import all twisted so using an animation sequence from poser may not work well. But once you straighten out the figure, you can animate them if you know how to do that in blender. Aside from simulations, the only animation I've done is a donut.

You can also use poser's strand based hair if you have a style you like. I have the steps in the blender forum. The biggest thing with it is to get poser to export it without crashing.

is there a script to export Poser to Blender like DAZ Studio? Or do you just export to Blender? Cheers

Unfortunately, you just export. With older versions of poser, there is a script that came with poser that will batch export everything under scripts>partners>dimentions3d> batch im-export. It doesn't work in poser 12 and I don't know which versions included it. It also doesn't include texture paths so you'd have to fix that in blender.

The original file wasn't compiled, at least not on my system. 
So that I've converted it to Python3. It can be launched from within Poser12. I'm not sure what its purpose is, but the problem is the copyright:

That's all.... volks

It depends on what you expect to do with the figure in Blender.  For my part, I'm generally sculpting the figure and move it back to Poser when I'm done.  In that case, there are some details in how you move things, depending on what you're exporting.

If you are sculpting an un-morphed unimesh multi-actor figure (from the source OBJ, not as Poser exports), then mainly keep vert order.  That makes Blender create its internal native Object in the same vert order which can be used as a morph in Poser (and DS, I think).  Assuming you only move verts around, exporting that mesh back out as OBJ can be used in Poser as a morph target.

If it's a figure that's been morphed in Poser *and* you plan to export it (modified or not) back to Poser to use as a morph (say, a Full Body Morph), then it's a bit tricker as Poser's OBJ export does not export a unimesh in the correct vert order.  This is due to how Poser splits the mesh when creating the figure from the OBJ.  Poser does not maintain a map of how the mesh was split.

I wrote a Blender add-on to help (it's not much code at all :)  It takes the original figure OBJ and an un-morphed poser export of the same figure (which is a disordered unwelded mesh) then creates a map.  Thjis map is used to take a morphed non-welded mesh and use it to form a copy of the base unimesh into the same shape.  You can then sculpt that unimesh in Blender.  The resulting mesh works as a morph target in Poser (and maybe DS).  The add-on takes about a split-second to do its thing.

Yes there is ! the disappointing part is that it was a plan to publish such a feature a few years ago in the forums. Matter of fact is that some Forum members disliked the idea and started to flame in these threads causing the ones who had the possibilities and knowledge to get banned from renderosity. Guess it was a fear of concurrence, so with the ones who would of already had working bridges between Poser and Blender all vanished with them, so the possibilities expanding Poser to a higher level. I do not believe that the remains of Poser experts would be able to build such a bridge, there Knowledge is to limited and if one would try bringing it back again the same would occur  like it already happen before !

From what I know there would even of been the possibilities changing older models with that bridge into wm with just a few clicks the possibilities of models would of been just out of your imagination for poser , might of even caused to raise poser over DS after many years. Irony is that some just dislike such ideas leaving these forums with Hobbyist that make big Bla Bla and allot of hot Air.     

This may be a stale thread but...recently, I've been using the Collada format for exporting from Poser 12 to Blender.  I was actually surprised how much came over intact (IK, textures).  The shader setup requires the most modification for me (proxy setup and material attributes).
