ok sorry i had to try working it....
kumar--- i tried what you are talking about on one nastrol and the pic below is what i ended up with....
1 that is the inner nose
2 some deformaties came out as a result of the doubleside poly
3 now i can see the jaw line throug the back of the head
i'm dumb founded
mark---what you are asking makes sence but where is it? i did find a dissolve but that was for that surface and it had the same result as the transparence.... but just a little whiter...
i know it is possable to do... have sene it on a movie... casper... the friendly ghost... he had eyes and all... but you could see though him... i'm so lost on this...
