When Im starting up a new scene or opening a saved scene in Maya 2009 (yes, old version, I know), mental ray in case of the empty scene is ONLY rendering the last geo greated even though I created multiple meshes in the scene. Its like mental ray is suddenly ignoring visibility on previous created mesh when a new mesh is created.
In case of the saved file with multiple objects, mental ray renders ONLY what happens to be the last modified object, regardless of changes in the settings.
Help much appreciated!
