Multiple elements and materials in a single export .obj

[matteo_noto]

Hallo

I have a model made by different components with different materials. I would like to export all the components using just one export button. Is it possible?

I can merge the meshes in one list and use the ShapeDiverExportDownload but what about the materials? When I download the .obj looks like everything has been flattened in a single mesh without the distinction of the different material properties.

Can you suggest me the best way to achieve it?
Thanks in advance

Multiple exports are currently only possible with a custom UI built on top of ShapeDiver viewer as explained below:

Regarding your need to trigger two exports at the same time: it is not directly a feature of the API. What I mean is that you can link a single button in your interface with a javascript function that will call requestExport() twice. Since requestExport returns a promise with the exported file, you can wait for both promises to return and do what you need with both files at the same time.

Also,

MTL file format as output is not currently supported but you can export a bitmap with the mesh model. OBJ file is exported with texture mapping so you can apply the bitmap later in your pipeline.

If multiple exports and materials are important to your work let us know and vote for the feature request here.
