I tried using Nano Banana Pro for UV unwrapping. It works, but the results still don’t meet game-ready asset standards yet.
@NanoBanana  Looking forward to future updates and improvements 🙌
Prompt:
unwrap the UVs of the 3D model shown in the image.
About one-third of the image should be a reference view displaying the 3D model itself.The remaining area should include the UV layout for the head, body, and limbs.Unwrap the surface of the 3D model and flatten it into a single 0–1 two-dimensional UV space.
