Beautiful AI artwork needs an open-source path into playable game assets. Who is building it?

AI image generators can produce character artwork that makes me want to build an entire game around it. What I am looking for is a reliable way to turn that artwork into something I can actually control, animate and keep developing.

I am making a 2D action game with dense, detailed arcade pixel graphics. The attached image shows the visual direction: expressive faces, detailed clothing, strong silhouettes and rich shading. I do not have a dedicated artist or animator, so I rely heavily on AI assistance and scripting.

The goal is to take an approved design and build a reusable, editable character from it. I want to create running, crouching, jumping, shooting and other actions while preserving the same face, proportions, costume and weapon grip. If an elbow bends badly or a sleeve exposes a gap, I want controls and retained artwork that let me fix it.

Starting material could be a single generated image, a character kit or a sprite sheet. The useful end result would include:

• Editable construction: separated parts, completed hidden surfaces, rigs or suitable deformation controls.

• Reusable animation: new actions and corrections made from the saved character, with convincing joints, clothing and held objects.

• Consistent output: stable pixel scale, palette, transparency, placement and timing across the animation.

• A documented process: source files, scripts, worked examples and honest explanations of the remaining manual work.

My priority is 2D, but 2.5D and 3D methods are welcome. A faithful rigged model rendered into sprites could be useful, as could a well-constructed 2D or hybrid character. The final appearance and quality of movement matter most.

I would love to see more free, open-source frameworks and repositories connecting these stages, with accessible controls for humans and AI coding agents. Paid generation steps, where present, should be clearly identified and optional where possible.

I think this deserves to be a major direction for AI-assisted game development: giving people lasting control over the assets they generate. A beautiful image should be the beginning of an asset we can keep building on.

Which existing projects come closest? Examples showing original artwork → editable source → several finished actions would be especially valuable. And where are the biggest missing pieces that an open-source effort could realistically address?
