To modify the armature : unselect "only render" (N pannel -> display -> only render). The armature is in the first layer.
To reset the armature position, go in pose mode, select all bones (A) and press altR then altG
You can control :
- Face expressions
- General position
- Tongue shape
This model is ready to render. You just need to add an hdri of your choice.
If you have a good computer you should render it easy (I have a 960GTX Nvidia).
If you have a no powerful configuration you can diminue the fur account (Particle pannel -> children -> render)
If you start the animation you will see that I added a "fat simulation". It is a softbody simulation on the bully. You can suppress it if your computer is slow.
