The testing process itself is an issue for many figures. (Speaking in GENERALnow)

Somebody makes an obj file. That goes to a rigger and a texture creator. (Sometimes the same person, sometimes the a team of friends)

Then "usually" : The builder of the obj file starts making the morphs.

When all is ready, they send it off to testers.

---

Now, "a" tester finds an issue with the obj file. WTF? ? ? ? The rig banana's, the texture banana's, most of the morphs => Banana's. => All that time, all that work "lost".

---

The obj file, the "core" of each figure should go in beta testing WEEKS if not MONTHS before starting the rigging, texturing or morphs to prevent this mishap.

Most errors can ( or the start of most if not ALL problems further down the line) can be traced back to the obj file.

Example : You can have the best rigger in the world. But rigging tubes is completely different from rigging legs.

For a tube you put the joint center in the middle of the tube. Bend, bend and done. You have a tube.

To build a knee, you ALWAYS put more geometry in the area's that go in stretch and less geometry in area's that go in shrink, and you put the Joint center where the actual knee joint is. => Completely different outcomes. => Where is the error? => Who created the issue? => Do you have to add JCM's or change the rigging? => NO, you have to cut the obj file open and add and remove geometry where required, and only then re-rig.

And the most important, and most ignored part is. . . What rigging to use? ? ? No,

The most important part of the rigging is where you put the Joint centers.
