Hi people... i'm new on this forum but have been following the project for quite some time...
I've seen a problem with abdominal muscular anatomy since RC came out, but admit that never got the initiative to say anything because i thought you wouldn't pay any attention... but given that you are making changes on the base model for next release... i decided to give a try...
Basically, the abdomen is NOT divided in 6 parts but in 8!... so actually y wrong to call it 6 pack...
Look at what i mean... see the four vertical divisions in the "Rectus Abdominis" Muscle
