Should I make multiple versions of my females, like one version for normal gameplay, another for the softcore scene, another for the naked scene, another for when whe takes the dick in the cunny, and another for when she gives head?

Because the blowjob model would require a diferent face mesh, unlike the other scenes, and the pussy taking dick would also require a mesh with a cunny.

The other meshes simply would have an alpha sprite with the mouth and cunny drawn.

Only thing I know about Wakfu is that animation with her and the blonde bitch. You know the one.
