When you start to upload from 3ds Max, you can put a slash in the asset's name, and the upload will go through. However, this results in an unusable asset on Cesium ion.
I believe the error is related to the fact that the file name under "Source Files" contains the slash.
When I tried to replicate this error by uploading to Cesium ion directly, it didn't modify the file name, so this is specific to the 3ds Max plugin.
