Resolution Note:
This may be an issue with the provided FBX asset as the fullWeights value is being read as 0.0 from the file. We do not plan to add additional validation for imported blend weights at this time.
Today we will be closing this case. Thank you again for taking the time to report this issue, and please let us know if there is anything else that changes the impact or severity of this issue.
