Yes you can. Came out a few days ago. Open pose has already support for it. You can not only render realistic hand and feet but also customize the hand gestures. There is a blender plug-in which let's you position your character pose including hand gestures in 3D and then render the needed controlnet masks. It works amazingly well.

Oh well that one you can edit with photoshop, otherwise it do creates way perfect images.

I guess you can always hate on things which aren't production ready yet. Considering the progress made in the last month's and the speed things keep improving it will most certainly have impact on how the industry works.

That being said, why are we only talking about stable diffusion. What about openai whisper? I have never used a better speech to text software and it is multilingual.
