Wanx Best Practices

Use this skill before calling Video Production Buddy WanxImage, the Bailian/Wanxiang image tool. This guidance is provider-specific to Wanxiang image models and must not be replaced with FLUX-only rules.

When To Use

• Generating still images with wan2.7-image-pro, turbo variants, or other Wanxiang image models exposed by WanxImage.
• Editing an existing image with natural-language instructions.
• Using one or more reference images to preserve product, character, or style consistency across a production set.
• Creating Chinese visual styles such as ink, watercolor, flat illustration, anime, portrait, photography, film, or product-packshot looks.

Prompt Structure

Write direct, visual prompts:

[subject/product] + [scene/action] + [style] + [camera/framing] +
[lighting] + [color/material details] + [composition constraints]

For physical products, anchor exact geometry and visible brand details in the positive prompt, then use a reference image when product fidelity matters. Text-only prompts are not enough for recognizable hardware, packaging, logos, or UI.

Negative Prompts

Wanxiang supports negative_prompt; use it when the scene has clear failure modes. Keep it concise and specific.

Good negative_prompt examples:

extra fingers, distorted logo, wrong product shape, unreadable text,
low resolution, watermark, duplicate object, melted edges

Do not copy FLUX guidance that says negative prompts are unsupported. For WanxImage, negative_prompt is part of the tool contract and should be used when it reduces predictable artifacts.

Model And Parameter Notes

• Use wan2.7-image-pro for higher-quality image generation or editing when cost and latency are acceptable.
• Use lower-cost/turbo variants only for drafts, bulk exploration, or cases where small artifacts are acceptable.
• Use explicit supported sizes from the tool contract, such as 1024*1024, 1920*1080, 1080*1920, or other WanxImage-supported width*height values.
• Use style only when it matches the brief. Prefer explicit prompt language for brand-sensitive output instead of relying only on a preset.
• Use seed when a production needs repeatable variations.

Editing And References

For image editing, state what must change and what must remain unchanged:

Change the background to a moonlit studio surface. Keep the phone shape,
camera island, logo placement, color, and reflections unchanged.

For multi-image references, assign each reference a role in the prompt:

• Product reference: preserve geometry, material, color, and branding.
• Style reference: borrow lighting, palette, texture, or illustration style.
• Pose/layout reference: borrow composition only, not identity.

Quality Checks

Before accepting Wanxiang output, inspect for:

• Product or logo drift.
• Extra objects, duplicate limbs, or warped hands.
• Text artifacts and unreadable labels.
• Aspect-ratio mismatch against the deliverable.
• Watermarks or provider artifacts.

If any brand-critical geometry is wrong, retry with a clearer prompt and the reference image rather than explaining the product in prose alone.
