Bug Report
3ds Max → Datasmith → Twinmotion
When using “Muitl/Sub object” material in 3ds Max, the ID is not imported correctly.
In the image, blue and yellow IDs are swapped.
Changing the IDs or changing the total number of IDs did not change the symptoms.
We have verified that this is not caused by Datasmith but by Twinmotion, as it works correctly in UE5.
Attached are the Datasmith and 3dsMax data used for verification.
