Texturing Avatar head problems

[S.Telemaque]

Hi,

Can somebody help me ? I'm having problems with my avatars faces made on 3DMeNow. At first they are well done on 3DMeNow but I have to convert them in vRML97 format on 3DS MAX, I'm using MAX8. 3DMeNow generate 2 textures : 1 for avatar face Bio_UV_head and 1 for eyes, teeth and tongue Ett_texture. My problem is to apply these both texture on the 3DS MAX imported head. I don't know why but only one texture can be apply when I do a morph pose !!! See pics below.











I've try many times to select mouth - teeth and tongue separately but it's really hard work to get inside the head and selected them separately....
Please help me, I have insuance date to finish these avatars to work with them in vizard for amination. Do you have a way to texture all the avatar head correctly please ???

Waiting for reply.... desperately.
