ok, thanks, i guess there is something wrong with my wed :-(
at least now i know that its not a problem from export with maya

i think im soon ok with this problem, im getting something


edit : it works too with color as basic project, but as soon as i do "file / project manager / walk-thru" (i want to do a walk thru project for start) then i remove "1st person camera", add "3rd person camera", right click on my model, "behavior", pibiped, and then i got my model in full black ig -_-' (other model as the basic earth have no problem t_)

+ i have a question if some people are not yet too much bored by me : when i want to rotate my model (the yellow smile), it becomes red (as all item when i select them) and it's "boring" for rotate it in the way i want (cause i don't see exactly where is the face). so im looking a tip for it too
