Materials#

Added#

  • Materials - The usd.mdl (Kit 106.1) and UsdMdl Kit 106.2 Python modules have been renamed to omni.UsdMdl. The use of either of the following in client code will result in a deprecation message instructing the user to update their code accordingly: import usd.mdl, import UsdMdl [OMPE-26130]
