i found the materialx operator assign to arnoldGlobalOption only support absolute assign. when node's path with different prefix can not be materialx operator selections in katana,and it will fail assigning materialx info.
how to resolve this problem?
You can do relative assignments by connecting the operator to a procedural, e.g. Alembic. The operator will then assign everything relative to the procedural's namespace. Relative assignments where the operator is global is not supported at the moment.
