Image to 3D Rigged Full Human Skeleton
Rigged 3D characters are fun to make, either find an image of the character you want, or even try using a photo of yourself.
The process is very easy, and it works with characters that are not in T-POSE, and also with characters that are carrying equipment.
Find Image
Find image of the character you want to generate a 3D model of.

T-POSE and exclude objects
To generate a 3D model that can be rigged and animated, we want to ensure the image of the character is posed in T-POSE. Use a free Image-to-Image model such as ImgToImg.ai
For this example I am using the prompt:
Remove the weapon. Set the pose to T-POSE
But if the character you are using does not have any weapons, simply use the prompt:
Set pose to T-pose
This is the result from ImgToImg.ai:

Rig and Animate
Sign up at Mixamo, upload your image and follow the instructions.
Result

You now got a animated full human rigged skeleton, which can be used in projects.
It is very acceptable grade for prototypes and early development, but be aware the vertices count is high, the topology is bad, and the texturing ain’t that great.
Disclaimer
Keep in mind when using assets generated using LLMs, that certain LLMs might be flagged later on for violating any terms (such as being trained on stolen data). To protect yourself legal wise, it is therefore important to store information about how the source of the asset, and which LLMs that has used to generate it, so those assets easily can be identified and excluded from your project to avoid legal implications.
