The largest size I can generate is around A4. Ultimately, I generate it as parts and then assemble them. However, it allows for more natural joins than simply inverting and printing a single photo and joining it. Getting the AI to understand the desired scene is more difficult than I expected... The sky is a photograph; generating it results in a uniform and unnatural look for the clouds and blue sky. In a photographic sky, things that are completely invisible before enlargement become visible upon enlargement. Birds, airplanes, and Take-chan Man. These are not imperfections, but part of the scene. With this method, I can generate other buildings, and the sequence continues: 7th, 8th, 9th, 10th, 11th... infinitely. Each additional sheet is 250 yen. Please specify how many sheets you need in your question. I will create a separate listing for your order. This is a simple construction with inkjet printing on 0.5mm thick cardboard. The non-glossy texture is good, but it is susceptible to moisture. Shipping will be via Click Post. Time-specific delivery is not available. Third photo: Larger buildings can be scaled down for N-gauge models. If there are no specific comments, I will send six sheets for HO gauge.
