# Turn a reference image into a game-prop prototype

## Quick answer

This is a concept-asset pipeline, not a shortcut to production-ready topology. Define a polygon budget and the target renderer before generation; allow time for manual cleanup in your existing 3D editor.

## When to use it

- Prototype environment props
- Client concept approval

## Steps

1. **Specify one non-critical prop** — Choose a licensed front-view reference and write dimensions, polygon budget, texture size, and required export format. Avoid precision or safety-critical objects. Tool: Notion. Expected output: Asset acceptance checklist
2. **Generate a draft** — Use Meshy image-to-3D with the chosen reference. Inspect the hidden sides and silhouette, and check whether your plan permits the required download and commercial use. Tool: Meshy. Expected output: One exported draft with licence notes
3. **Compare only if the first draft fails** — Try Tripo with the same reference and acceptance criteria. Keep the better candidate; repair normals, UVs, and mesh defects in your existing 3D editor instead of endlessly regenerating. Tool: Tripo. Expected output: Selected and cleaned asset
4. **Validate in the target scene** — Import into your game engine. Check scale, textures, lighting, file size, and frame-rate impact. Attach three screenshots and record unresolved defects before marking it usable. Tool: Notion. Expected output: An engine-tested prototype and defect log

## Prompt templates

### Adaptable task prompt

For [prop] in [engine], create an acceptance checklist using [polygon budget], [dimensions], and [texture size]. Separate visual checks, technical import checks, and licensing checks. Do not claim an image proves manifold geometry.

## Common mistakes

- Assuming a pretty preview proves usable geometry
- Forgetting commercial export restrictions
