I've almost worked through my collection of MD/AD freebies using C-D.
Like the old saw about 'Dancing Bears', the wonder is that programs such as WW or C-D work at all, never mind so well !!
Gloves, some shoes, several dresses will NOT convert for Posette. A few items' re-grouping leaves zig-zag seams or features, leaving them un-sightly if textured.
Many AD freebies come as a PZ3 that cannot open without the commercial AD character installed. Other AD PZ3 files allow saving of a garment, but their resulting CR2 contains a 'string reference' instead of a 'hard' location for OBJ, so defy conversion. There are free 'mesh ripper' utilities on eg Renderosity, but they would be a last resort.
Against that, many MD/AD garments were easily converted, with excellent fit, often using default C-D settings. Some tops required slight tweaking using C-D's generic, under-arm and/or upper-side poke-through fixers. Several garments had problems on the pelvis, a few requiring *heroic* tweaks to clear...
I've now begun converting Aiko items. I deleted my original experiments as I now understand C-D better, and must arrange converted files more systematically.
A big problem with A3 is 'body morphs'. C-D cannot cope with garments tailored to a much-morphed character: Technically, it becomes a different character, requiring a new conversion matrix. I discovered this when trying to convert a smart ChrisT item, the red 'coke bottle' corset. After a dozen exasperating iterations, I went back to C-D's default settings and morphed the result using Poser's XYZ dials. Although obviously 'off the peg' rather than bespoke, this now fits the default Posette...
After filling Posette's wardrobe with MD styles, I only need a few Anime-ish Aiko items before tackling some classic V1/V2 garments.
Then I'll switch to converting Medieval-ish garb again. I have not tried adapting any more robes for P4M since my first attempts lost either the complete hip region, or everything below it. This may be a bug in C-D, a problem with P4, an artifact of Gloria Ghast's notoriously quirky old meshes or some combination. I'll need to do a lot more experimenting to spot a pattern. It may just require re-aligning either the original or C-D's output OBJ by opening / re-saving with UV-Unwrapper...
Um, would anyone mind if I posted a few low-res piccies with 'before and after' ?? I am not striving for photo-realism, just assembling enough costumes to visualise key scenes in several surreal short stories...
