Originally posted by GecT Those are just progress messages. You probably have "Echo all commands" checked on (it's under the "History" menu in the script editor) Uncheck and much clearer now! And the warnings about the IBL node are there because you most likely clicked "Image Based Lighting" in the render settings and never bothered to assign an HDRI image to it so it stayed at the default black (which will give you no illumination), Mental Ray is just giving you a heads up. Is this in the mental ray settings? Other than that question I would say HUH? ;-) Also, if you assign a new shader to your wolf and it's still not rendering, post the scene and let's have a looky loo. [/B] Didn't do this. Just tried to do a test render. BTW I moved the POV of the scene around a couple of times and all of the model started to render. Moved it back to it's original location and it rendered OK.... so now I am scratching my head. I have got to say the Maya is one complicated cookie. I know photoshop pretty well and have done lots of programing but Maya has got most things beat in it's complexity. Thanks for the help :bow: d
