Meshy 5 Retexture

Meshy 5 Retexture synthesizes a full 2K PBR material set comprising diffuse albedo, roughness, metallic, and normal maps. When PBR mode is active, each generated map aligns with the underlying mesh topology, allowing assets to react accurately to dynamic lights and reflections in modern rendering engines like Unreal Engine and Unity.

The model accepts closed 3D meshes in GLB, OBJ, FBX, and STL formats under 50MB. For optimal projection and performance, input models should be under 100,000 to 200,000 vertices with manifold geometry and consistent face normals.

Enable the original UV toggle before running the model. This instructs the synthesis pipeline to project textures directly into your pre-existing UV islands, which is ideal if you have custom unwraps prepared in Blender or Maya. If your model lacks UV coordinates, disabling this option allows the model to automatically unwrap and pack new UV islands.

Yes, you can provide a 2D image reference swatch to guide material generation. When an image URL is supplied, it overrides the text style prompt, transferring surface colors and textures directly onto the mesh. For the best results, use cleanly lit, flat swatches without complex background clutter or perspective distortion.

Avoid relying on the model for crisp typographic logos, vector decals, or legible text labels, as lettering is frequently garbled. Additionally, open non-manifold meshes and extreme micro-detailing on biological faces may exhibit texture stretching or color bleeding along tight occluded seams.
