3D Character : Closed mouth Baking

Ernos

Hey! So I'm making my second ever 3D Character, and it will be rigged and used for VRChat so I need the inside of the mouth to be textured and modeled.

I saw about as many people saying to sculpt with open mouth, as I saw people doing the opposite, both with good arguments.

I went with closed mouth, and as I'm about to start my retopology, I am doubting my choice :

When I will bake my highpoly onto my retopologized low poly, the closed mouth probably won't be baking properly, everything will be dark with the Ambient Occlusion, for example.

Is there a way around that, or should I just go with open mouth for the sake of making my job easier, and then closing it later?

I got in the habit of keeping the mouth slightly open because it makes rigging easier too. then after the rig i use a blendshape to correct the mouths neutral position so that the lips slightly overlap
