3Dsmax baking - don't hit backface?

olivierth

Hi,

I've created a high res head with the mouth closed but the lips are not welded together so it's possible to open the mouth. I created a low res the same way and I would like to know how to bake the normal map without detecting the backface.

The reason for that is some of the upper lips will bake parts of the lower lips. Is there an option for that? Do I have to actually open the mouth just to bake the normal maps?

Tell me if I'm unclear.

Thanks.

It can be a good practice to open the mouth and close the eyes slightly. That way you avoid deep creases around the mouth and "dirty eyelids". Morph targets/blend shapes can help with that.

Yes but I would still like to know if it's possible not to hit backface as it would be super usefull for other complex bakes.
