Ive been messing around with modveiw, trying to put the hands, legs and head of the trandoshan model onto other models. However i cannot get the two models to 'line up'. None of the tags seem to be in the right place, and sometimes the models come up at reduced size. What i need is a tag in between the models legs a bit above the knees, or the ability to change where the main model attatches to the secound one.

Can i make this work and will the result in game be one models body 'wearing' the trandoshan head hands and legs?

I'm not sure but I would say that you would need a modelling program in order to do this correctly.
