This course contains a little bit of everything with modeling, UVing, texturing and dynamics in Maya, as well as compositing multilayered EXR's in Photoshop.

Rendering question

I have two screen shots for you. One in the editor with smoothing on ( 3 ) on the keyboard. The second is the render of this screen. However the render looks like it had smoothing off ( 1 ) on the keyboard. My question is does Maya not render as what is seen on the screen. If not how can I render this model at a higher resolution. Thanks in advance!!

In the editor

Render

Because the software renderer doesn't support the smooth preview. Mental Ray however, does.

Thanks. Looked into that and 1) didn't have the plugin activated BTW thanks for your FAQs as that is where I found this little nugget. Now I have tried to render with Mental Ray and I have a new problem. Nothing renders except the complete eyeball. I have looked around and made sure that all of the layers are selected as being rendered but it still is rendering just the eyeball. Also found a couple of warnings in the script editor and have included them below.

Thanks again.

Those are just progress messages. You probably have "Echo all commands" checked on (it's under the "History" menu in the script editor) 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.

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.

Uncheck and much clearer now!

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:

Yes, its in the Mental Ray settings, in the "Indirect Lighting tab, under the "Environment" section (should be the first thing at the top of the tab).

Uhh you're not supposed to have to move the camera around to get a scene to render but I don't think I have to tell you that lol. I don't recall ever having that happen to me, it would drive me nuts until I got to the bottom of it.
