Exporting Physical material/ Vray Material ( Ambient Occlusion Map ! ) to USD Composer

Hello everyone, I have a question about exporting 3dsmax vray or physical materials to Omniverse:
where should I put ambient occlusion maps in physical or Vray materials to open correctly in Omniverse USD composer?
I tried all the different slots in physical material and Vray and just the ambient occlusion map does not export correctly.
I tried composite map and other slots and they do not work for me!!

It is not supported by physical material and Vray. You can use MDL material in Max Connector via Max’s Material Editor, e.g. OmniPBR and set it to ORM_texture and make it enabled.
