Well found out that probably the only solution for my problem will be aplaying the blendshapes before skinning him BUT redoing all the weights wont be fun so im trying to export the skin weights then un bind him, the make the blendshapes and apply them and last re bind him importing the original skin weights. BUT after doing all this process, when i put to import the weights it just gives me result 1 in the script editor and doesnt change the weights. well i unwraped the head and exported the weights as a jpeg and i checked the images and they got the weights oin them.. so the problem is the importing process.... anyone plz know why this isnt working!? its supposed to be so simple and its turning in such a big nightmare...
thanks anyway..
