Hello @gudwnzm! Thank you for your interest in Isaac Sim.
The problem here is that even though Isaac sim was defined to default to meters, the Create App and extensions built for Create as a whole still defaults to cm, which is the case for the 3ds max importer, so you’d still need to run it through the unit converter to convert it back to meters.
Regarding your code, it’s hard to clearly understand where is the issue without the full stack trace. would it be possible to paste the entire log of where its failing?
The reason for that is that the errors we can see in the video are possible due to some error that happened before, which prevented the attributes to be created, cascading on additional errors ahead in the code.
