I would like to create morphs for a garment created for La Femme 2 in order to adapt it to dawn 2. I made the modifications in poser with the
adjustment wheels and the morphing tool and it works well but I cannot save the morphs to then apply them to the initial dress. And I can't find any tutorials to do it. Do you have any suggestions? I managed to save the morphs (and I have a new morph setting in my dress) but not the adjustments with the adjustment wheels thank you for help.

OK.  The easiest way to do this is as follows: (Make sure you save your project before trying this)

1.  Select the modified garment with all of your morphs (ones created with the morphing tool, and others with parameter dials). Make sure ALL of the morphs you want to combine together are set as you need. 

2.  Choose Figure > Spawn Full Body Morph.  You'll be asked to enter a name for the morph.  Example:  Dress for Dawn 2

3.  With the outfit still selected, choose Figure > Zero Figure. This zeroes out all of the morphs you dialed in.

4. Now Dial in ONLY the "Dress for Dawn 2" morph that you spawned. You should see exactly the same thing you saw when you had the morphs individually set.  DO NOT delete this from the scene. You'll need it for the next step.

NOW ... Here's the key.  You need to create a new DEFAULT SHAPE for your clothing, and the vertex order has to be the exact same result as the original OBJ file for LF2, otherwise the morph won't work properly.  To do this part:

1. Import the OBJ file (not the CR2) for the garmet you modified.  Typically located in Geometries folders. So let's say your original OBJ file is named Dress for LF2.OBJ. 

2. Select Dress for LF2.OBJ (substituting with your OBJ name, which will be listed under the Props category)

3. Choose Object > Copy Morphs From. Expand the menu to select the Dress for Dawn 2 CR2 that is in your scene (it's generally the choice at the bottom of the selector list). Then choose OK.

4. Click the Select None button at the bottom of the dialog. Then select ONLY the Dress for Dawn 2 item in the BODY actor.  That will automatically check all of the various body parts included in that BODY morph.

After you create the morph, go to the BODY actor and dial the morph to 1.  

Now you can export THAT OBJ and name it whatever you want to name the clothing object for the Dawn 2 dress. Note though that Dawn 2 has an extra abdomen2 body part that LF2 doesn't have so you may need to do some manual regrouping.

If you need more help let me know. 

thanks I will try that :)

Usually I just take the original clothing OBJ into my modeler, placed over the target figure, and then morph the dress in my modeler directly. I have more control over things that way, and then can save it to a new file name.

3 doesn't work, my morphs didn't disappear, maybe because it's a prop and not a figure. It's a dress in props for dynamic.

I'm assuming you're converting your LF2 clothing to Dawn? I have the Vintage Dress will you do that one?

no it's a new dress that I created for LF2, I want to offer both versions. For the moment it is at the obj stage for LF2 and I modified it in poser so that it adapts to Dawn and I recorded this version as props. the dynamic works well for both versions. I could propose 2 props one for LF2 and one for Dawn but I would like to try to propose only one version with a morph for the adaptation to Dawn with the modifications that I made.

What do you normally model your clothing in? It might be a lot easier to fit the LF2 dress to Dawn 2 in your modeler, 

I model with hexagon, you might think so but I found it easier, faster and more efficient to do it in poser, offset with the wheels and morphing tool for the pocks and adjustments. But that doesn't give me the solution to save the morphs created in the dress, finally the morphs are good it's the offsets with the wheels that I can't save.

I did it !!! in fact I had forgotten the step of saving in obj my dress modified for Dawn in props. Thank you a thousand times, it works, in my dress for LF2 I have a wheel that allows to adjust to dawn perfectly (morphs and wheels) yesssssssssssssss

Good deal, glad you got it working!
