First of all, thanks for the replies

Genesis is not an option for me since I use Poser LaurieA
the option of scaling a M4 might be useful , i will try ....

I congratulate for your model in zbrush **JoePublic **, ¿is a M4 morph or a new character? unfortunately I have not the skills to make myself do a morph like yours in zbrush

I hope ( now has fixed the scaling issues) it goes on sale some teenage morph that allows me to use my M4 things , or a tuto to make it for myself
