Important Notice: ResPower's support for uploading .mi files is officially obsolete. This means that it is no longer supported, because new and improved processes are available. For Maya, mental ray rendering is no longer supported at all as we no longer purchase licensing for the standalone mental ray product. For 3ds Max, please upgrade to version 8.0 or later; you may now upload your .max file and it will render inside 3ds Max, exactly as it would on your computer.
