3D (object & textures) · community

We have recently enabled the 3D preview feature and noticed that when uploading an .OBJ file, the system does not detect it correctly and instead displays it as a .TIFF. However, the file is displayed correctly when modifying it directly in the database. Based on this, we have created a script that could resolve the issue.

However, our users would like to combine .OBJ files (for the 3D model) with .MTL files (for textures), but we see that the preview does not render correctly.

Has anyone developed a solution for this or worked on a similar issue? Could it be that we have not applied the code correctly?

Apologies if this has been asked before. We would really appreciate any insights!

Thank you

Hi! Thanks for the feedback!

It sounds like there are multiple things going on.

@Mireia Alcala would you be able to create an issue at https://github.com/IQSS/dataverse/issues with a title of something like ".obj file detected as tiff"? And please upload an example .obj file if you can, so we can test with it.

As far as I know, previewers only operate on a single file. Perhaps you can create an issue over at https://github.com/gdcc/dataverse-previewers/issues describing how you'd like to combine .obj files with .mtl files. Again, if you can upload example files, it would be helpful!
