hoplaa : Ya, i know this program, but i prefer to work on a welded mesh: it's much simplier and quicker to get the desired results

Mike:  for the trans maps, really I don't mind: the simpler for you will be ok

What i'm worry about it's that the mesh doesn't seem to be symmetrical: for example, the line of the central vertices of the hip is shiftted on the X axis around 30 um (micro meter) from the center of symmetry (plane YZ) when the same line on the head is shifted a little bit more  (around 130 um) .
As a result, for example with modo  I can't apply symmetrical deformations, nor use the symmetrical tool to make this mesh symmetrical :m_cry:
The central vertices of the mesh must be on the YZ plane for my progie to work in a symmetrical way (at least, to the extend of my knowledge, may be there's a way but i don't know what it can be)

If you could have a look at that it would be great

Cheers
