Why there's visible seams ?
Both versions of PlayPussy are aligned perfectly with Maitreya body. However, the "seams" observed was actually caused by the difference in light reflection. Therefore, the "seams" is more obvious in certain windlights or light source direction. Pelvis version does have a more seamless appearance because the joint line happens at a flatter area.
Suggestions / Solutions
1) Use the Pelvis Version,
2) Use a more forgiving windlights setting, such as Nam's, Cawl etc.
