Hi, i'm having a problem rendering with mental ray. I didn't change any of the settings, just did a test render. Rendering with maya software gives no problem. See the pictures below. The script editor gave the following message. // Warning: (Mayatomr.Geometry) : polyToSubdShape1, subdivision surface contains creases on boundary edges which are unsupported and have been ignored // I only creased the outside of the door and the inside of the window. thx in advance.
