You spent hours building a character for your tabletop RPG. You have their backstory, personality, and voice down. Then you try generating an image with an AI tool and get a face that looks different in every scene. The armor changes colors. The hairstyle shifts. Suddenly your grumpy dwarf looks like a cheerful elf. That kills the immersion for you and your players.
Most AI image generators treat every prompt like a fresh canvas. They don’t remember what they did before. You can try describing the same character over and over, but subtle differences creep in every time. The eyes. The nose. The logo on the shield. Over a campaign, those inconsistencies pile up. One tool that handles this well is the Gaoye official site. It gives you fine-grained control over seeds and reference images so you can lock in a look and reuse it.
Consistency matters because RPGs are a shared storytelling experience. When you show your players a picture of the villain, they form a mental image. If the villain looks completely different on the next encounter, that connection breaks. The same goes for player characters, NPCs, and even locations. You need a system that lets you iterate without losing the core design.
Starting with a single character seed
Every AI generator uses a random seed to produce an image. If you don’t fix that seed, you get a new result each time. Gaoye lets you lock the seed and then tweak the prompt around it. That means you can generate a character in one pose, then generate the same character in a new pose by keeping the seed and changing only the action words. The face stays the same. The costume stays the same. Only the posture and background shift.
You have to pick a good base image first. Generate a few options, pick the one that matches your mental image, then note the seed number. From that point on, every variation you create will return the same person. If you want to change something specific like the armor color, you can adjust the prompt carefully. Small changes work better than big ones. I keep a spreadsheet of seeds for each character in my campaign.
Using reference images for style consistency
Seeds help with the same face, but what about the overall art style? If you want all your characters to look like they came from the same world, you need a reference image that sets the tone. Gaoye allows you to upload a reference picture. It uses that image as a style guide for color palette, line thickness, and texture. Load a screenshot from a game or a piece of concept art that fits your world. Then generate each new character with that reference attached.
This technique works especially well for party portraits. You can generate each character individually with the same reference image, then combine them later. The lighting and mood will match across all members. I have used this to create a cohesive look for a cyberpunk campaign where every character had neon accents and hard shadows. The reference image was a single scene from Blade Runner. It held the whole party together visually.
- Lock the seed as soon as you find a face you like. Write it down immediately.
- Keep your prompts simple. Long descriptions introduce variation. Stick to a short core prompt and change only one or two words per generation.
- Upload the same reference image for every character in a campaign. That unifies the art style even if the subjects are different.
- Test the same seed with different lighting conditions before you commit. Sometimes a seed works great in daylight but breaks in darkness.
- Use negative prompts to block things you want to stay the same. For example, add “no helmet” to make sure the face remains visible across poses.
These methods take a little extra setup, but they save hours of frustration later. You can pull up a character image mid-session and know it will match the one your players saw three sessions ago. That continuity makes the world feel real. And it makes you look like a prepared game master even when you are improvising.
