SnowDrop MarketReady is a Blender add-on for checking .blend files before marketplace upload, client delivery, or archive handoff.

It runs locally inside Blender and creates a clear audit report for common delivery issues such as default data-block names, missing or unpacked image textures, transform problems, mesh cleanup risks, orphaned data, and unsaved files.

What It Checks

- Default-style names for objects, meshes, materials, images, scenes, and collections
- Missing, unpacked, pathless, and very large image textures
- Camera, light, and mesh material readiness
- Negative scale and unapplied object scale
- N-gons, zero-area faces, loose edges, and non-manifold mesh edges
- Unused mesh, material, image, and collection data blocks
- Saved file path and configured .blend file size limit

Reports

MarketReady exports Markdown, HTML, and JSON reports. Reports include status, score, issue counts, suggested fixes, and an Audit Coverage section showing which checks were performed.

Fix Helpers

- Rename Defaults: renames default-style data blocks with a custom prefix
- Pack Images: packs external image files into the .blend
- Purge Orphans: removes unused data blocks
- Open Last Report: opens the most recent exported report, exporting one first if needed

Who It Is For

- Blender asset creators preparing marketplace files
- Artists delivering .blend files to clients
- Small teams doing a final cleanup pass before upload or handoff
- Creators who want fewer broken texture paths, unclear object names, and avoidable file-quality issues

Installation

1. In Blender 4.2 or newer, open Edit > Preferences > Get Extensions.
2. Choose Install from Disk.
3. Select the snowdrop-marketready.zip file.
4. Enable SnowDrop MarketReady.
5. Open the 3D View sidebar with N, then choose the MarketReady tab.

Notes

SnowDrop MarketReady runs locally and does not upload files, make network requests, or require an external account. It is a checklist and reporting tool; it does not guarantee marketplace approval, but it helps catch repeatable file-readiness issues before upload.
