Dear community,
Uploading OBJ data, when the main .obj filename is not aligned with the .mtl material filename, CESIUM.ION is not able to process the 3D Tiles and fails.
This comes as a surprise, as the material filename is usually included inside the .obj as below.
Using the same data but renaming the main .obj file, one succeeded and the other failed.
If any restrictions applies regarding naming conventions, please let us know.
Thanks for your amazing work!
