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.
First, analyze **the source image (flower, clothing, pattern, etc.)**. Instruction to ChatGPT: "Convert this image into a JSON prompt, including size, color, shape, and details." Instruction: "Metaprompt Goal: Create a prompt for NanoBananaPro that draws the specified texture onto a UV deployment map. Perform a process similar to Substance Painter, generating the texture by referencing image 2 against the UV map. Based on this JSON, create a prompt to change the color by referencing an additional image. Aim to create a prompt template in JSON format that generates a skirt texture on a UV map. Clearly instruct NanobananaPro to create the color based on this image. Generate a single prompt JSON according to a predefined JSON schema: ..."
