Texture Creation via JSON and UV Map Metaprompt

A two-step process for creating textures using Nano Banana Pro. First, an existing image (e.g., flower, clothing pattern) is analyzed by ChatGPT and converted into a detailed JSON prompt describing its size, color, shape, and details. Second, this JSON is fed into a specialized metaprompt designed for UV mapping, instructing Nano Banana Pro to paint the texture onto a UV deployment map, similar to Substance Painter.
