Hi, check this post on another thread: https://www.renderosity.com/forums/comments/4475623/permalink . And for more detail on the rig/zones/morph transfer I suggest the video tutorials from before, still helpful: https://www.renderosity.com/premium-tutorials?section_id=1&page=3 (starting from LFDevRig1-GettingStarted).

Here a copy/paste from that post:

It would be nice if EvilInnocence could release a LF2 CrossDresser license. ATM, my workaround with conforming clothing conversion involves several steps which may or may not work depending on the clothing and for whom it was made for. My work flow is as follows:
1. Use the LF2 Morph Tool to change her to LF and fit the LF clothing to her.
2. Convert the clothing to a prop in the Fitting Room.
3. Run a simulation in the Cloth Room, morphing LF2 back to her default shape while allowing the dynamic prop clothing to fit.
4. On the final simulation frame, take the fitted clothing back into the Fitting Room and convert it back into a figure, transferring the body parts and morphs as necessary. Note: When using the Fitting Room, do not run any simulations for fit, just convert the clothing.
5. Go back to the Pose Room, conform the clothing to LF2 and copy the Joint Zones.
6. If you use CrossDresser to convert clothing from a different figure to LF, your rate of success will vary. I have experimented with AerySoul outfits from V4 using the outlined process above, and those are a disaster. You always get stray vertices moving during the Cloth Room simulation.
If anyone could provide a better alternative, just using Poser as opposed to 3rd party programs, I would be greatly interested in the process.

If you have LF2 Pro, there's an easier process (as in, no need for a simulation and won't fail in clothing details that could fall off):

1. Import the clothing's obj from the geometries folder into Poser

2. Load LF2 Pro's LF1 to LF2 Prefit Tool from the props library

3. Copy the LF2 shape morph from the tool to the clothing obj

4. Export that obj

Now you can import that obj in a new scene and take it through the fitting room or setup room :) Using the dev rigs as donor will be better than using LF2 herself, but both will work as a start. Remember to Copy Joints From after that, if you're in Poser13.
