If you mainly use Firefly for your renders, I'd stick with Poser 11. The one big advantage of Poser 12 is that Superfly works much faster than in Poser 11. However, they screwed up the material room by removing the simple tab.

Here's a conversion of a dynamic gown for La Femme using our MFD that I also rigged for G2F and PE. This is Outoftouch's Cynthia for La Femme wearing Elegant Provocative, Fatale heels for V4, and Anna Rose hair for G8F. I found the materials included with the garment uninspired, so here is and elegant and proactive material set I put together.

This thread offers other clothing conversion options that you could adapt to any figure. 

I use the obj export method, although some giant scenes (Harpsburg comes to mind) don't transfer all the material zones. In that case, I exported the individual buildings, too, so I can fit them on top of the untextured parts of the mesh. Also, DAZ changed something in the obj export utility, and you now have to find each individual texture as the obj loads in Poser. This can take a while. The materials used to transfer automatically with the mtl file. I assume they did this to make life harder for people converting material to Poser. Thanks for the tip on Colada format! I'm also on a Mac. so I can't run the DSF tool. Also, when you import an obj, select the option for a standard figure. This makes huge and tiny objects visible.

Whatever you missed, you can fix all that now with the morph brush.

How I Stole the Show

 I was converting Natasha Rose for G8F to La Femme when I encountered the problem of the stole. The original is that black rectangle on the ground that I guess you are supposed to dForce over the shoulders. I could think of no substitute from another outfit. Then I recalled a towel set for M4 that included a rigged towel that draped over the shoulders. That is the pink thing to the right, scaled to perform its new function. Apply a Poser lace material to the towel and parent it to LF. It looks good!

Just conform V4 hair to La Femme and copy joint zones from. That works with most figures. 

Also, PE, a Poser figure,  comes with several ethnic characters built in. 

Hello? Paul and Pauline, the official figures of Poser 11 (to whom La Femme was a late addition), both have ethnic variants out of the box.

Oh, I should mention that you should also pose the feet in DS so the body of the shoes are at the zero pose for Poser figures before exporting your obj. Assuming, of course, that they don’t load that way. 

Shoes are easy. G3F shoes usually load in the zero pose for the feet, so just scale them a bit and rig down to the toes. If they are not zero posed, tilt them on the x axis until the shoe body is lined up with the zero foot pose. You have two choices here. Bend LF's toes to match the shoe and rig to the toe. You'll have to pose the shoes' toes when you conform. Or if the shoe is rigid, just rig to the foot.

Its more or less the same deal with G8F. Sometimes they are rigged in DS and you can pose the thighs to get close to LF before you export the obj, Then proceed as above. Otherwise, set LF's legs to match the A pose {this is where moving the shin sideways helps), then rig to the foot or toe as appropriate. Zero LF, then pose the new shoe character to match her, and rig it again.

I decided to do Rochelle Gown for G8F to try a full garment with hanging sleeves. Fortunately, the garment is rigged, and I could pre-pose it in DS. This turned out to be more complicated because the fitting room was auto grouping part of the hips and thighs to the sleeves because the gown was wider the the Furisode dress.

I therefore rigged the obj to La Femme down to the feet and hands using LF not zeroed as the goal with her arms posed to match the gown. Then I used the thighs to narrow the skirt and reduced the body on the X axis. This left poke through, but that could be fixed later

The fitting room properly assigned the draping to the sleeve rigging this time. I conformed the resulting garment to LF. Like with Furisode, I had to move the hip forward and up and pose the abdomens and arms. Next came the morph brush work to eliminate poke through. Then I saved a pose of the final garment is the pose library as I did with Furisode. I created a full body morph to speed conforming next time. I copied the morphs from V4;s MFD to provide beaucoup skirt controls. Then saved the garment.

So I now have a donor rig for future conversions of gowns with drapes sleeves.

As I mentioned when I discovered how easily Furisode for G2F conformed to La Femme, I wanted to try to use it with Genesis 8 clothing with dangly sleeve things. I picked Harmonia, which turned out to have sleeve ribbons separate from the dress. A lot of dForce garments are actually also rigged, which allows you to pose them to a T-pose in DS before exporting can obj to use in Poser. These arm ribbons were not rigged at all. Loading the garment into Poser, I tried using the fitting room with LF in an A-pose. Auto fit broke the long ribbon and assigned half of it to the hip. No luck there!

So, I thought, what could I use as a donor to rig the ribbon in a usable way? Then a thought occurred to me: Strigoi wings for V4, which I have conformed to LF and copied joint zones to it. I posed the wings and then used the fitting room with the wings as the non-zeroed target.

That worked nicely! The ribbons were conformable as a unit but slanted at the angle of the wings. So I posed the ribbon. That was fairly good.

So now I needed to change the ribbons to hang down to match Furisode as a donor. I used the pull tool (screen) to morph one ribbon and mirrored it to the other. There was no keeping it a rectangle, but the result looked like the end of a dangling ribbon.

Now to use Furisode. I moved the garment to line up with the ribbons and used the fitting room to copy the bones and morphs.

The result was ribbons that conformed and had "sleeve" bones and movement morphs. I rigged the dress with the MFD LF created earlier in this tutorial and then rigged the sandals. I rate this a successful experiment.

I also have found L’Homme to be a train wreck in the fitting room. I didn’t realize that his scale and morphs aren’t zeroed. That’s just stupid. I now use only the original morph of La Femme, rig for her, and copy the morph and joint zones. 

I hope we are going to see the TT converter for La Femme that she says in the interview is finished!
