How to find and set the Arnold Opaque flag in C++ sdk

[Anonymous]

What object has the Arnold Opaque flag? I need to clear it in my MPxCommand plugin.

It is not on the mesh I created, though it looks like it is in the attribute editor.

Where has Arnold added those attributes?

I checked before and after assigning Arnold shaders to all the surfaces.

I finally have all the transparency maps working correctly in Arnold, but it requires me to manually turn off all the opaque flags after my import command has run.

Thanks

Finally found the correct spelling - aiOpaque by dumping all the attributes on a geometry node.
