Hi All,
I tried using the weld option on a single figure and it fixed the limb texture join issue and the jagged shadow on the chest.
The shadow between breasts is still a little dark and angular but I guess (based on your replies) that it is due to the large crease angle between breast and chest.
Thanks for all the help.

FlyerX,
PoseRay is a great tool. Thanks for all the effort you have put into it and the technical support.

Regards,
Jovial.
