Lock a fixed seed, feed the same reference image or trained model into every prompt, and generate all poses and animation frames of one character in the same session or batch rather than one-off prompts. Fix lighting and proportions first; fix color palette last.<\/strong><\/p>\n

The single biggest lever is reusing the same seed and the same reference input across every generation of one character. Most sprite tools that expose a seed field (Unity’s Sprite Generator, for example, lets you “specify a custom seed to generate consistent results”<\/a>) will reproduce near-identical proportions, palette and pose framing if you keep the seed fixed and only change the pose or action words in the prompt. If your tool supports training a custom model on your own reference art, use that instead of prompting from scratch each time – Scenario’s platform is built around custom model training on your proprietary data and art styles<\/a>, which locks the character’s look far more reliably than seed-matching alone.<\/p>\n

Once assets are ready, tools like Playgama MCP<\/a> let coding agents create entries, upload builds, and test playability.<\/p>\n

Practical order: 1) lock proportions and silhouette first (body shape, head size), 2) lock the palette next, 3) generate all poses\/frames of that character in one batch or session so lighting stays flat and comparable – useful for sprites, since sprites are generated with flat lighting and shadows removed so they can be animated or composited cleanly<\/a>, unlike general asset art. Generate rotations and expressions from the same base image via image-to-image rather than fresh text prompts each time.<\/p>\n

Pitfalls: switching model versions mid-project breaks consistency even with the same seed; cropping or resizing a reference image before feeding it back shifts proportions; and portals like Steam ask you to disclose AI-generated content in review, so keep your reference set and prompts documented as you go.<\/p>\n
