Metashape Round Trip

Step 3: Build Texture in Metashape

Using metashape-mcp tools:

1. build_uv(mapping_mode="generic", texture_size=8192)
2. build_texture(blending_mode="mosaic", texture_size=8192, ghosting_filter=True)
3. Mosaic blending produces the sharpest results for road surfaces

Step 4: Export Textured Model from Metashape

Using metashape-mcp tools:

1. export_model(path="/path/to/exchange/Tile_X-Y_textured.fbx", format="fbx", save_texture=True)

Step 5: Import Textured Model into Blender

1. import_fbx(path="/path/to/exchange/Tile_X-Y_textured.fbx")
2. Verify texture is applied
3. Verify geometry matches (face count should be same or very close)

Coordinate System Notes

Common Pitfalls

• Scale mismatch: If the re-imported model is 100x too large or small, the CRS units in Metashape may be degrees instead of meters. Check Metashape chunk CRS.
• Texture not appearing: Blender may not auto-assign the texture to a material. Check the material's image texture node.
• UV overwrite: Metashape's build_uv will create new UVs. The top-down projection from Phase 5 of cleanup will be replaced.
