In order for clothing to work in Poser software (DAZ, Poser, Reallusion), it needs to be in A-Pose. To get real clothing to work in needs therefore to be scanned on an A-Pose mannequin. The next step is to separate the doll from the clothing. Once all that is done, it looks like the clothing was photographed on a ghost mannequin.
Before texturing, the mesh needs cleanup.
Over the past 10 years, I’ve scanned 100’s of costumes, props and casual clothing. You can find those items, among others, on Polygonal Miniatures. Clothing is sold under editorial license. For commercial use, the owner of the clothing is involved.
I hope you enjoyed this little exposition. Until next time!
