Unfortunately in Crazytalk 8 the 3D render settings and polygon count of the models are fixed and can't be adjusted to further smooth out the models. If you want greater control over your 3D models, you may prefer to use iClone 7 which has many more options to improve 3D rendering.
Alternatively if you find the CT8 3D heads are not high enough resolution for your needs, you can use a high resolution photo and create a 2D head in CrazyTalk 8 instead. This will add to the realism and offer a more photorealistic look when exported to video.
