Rendering in Wireframe
This is a little tip that helped me make a fairly good effect for my showreel (even though im still working on it ).
Ever wanted to have a piece of video blend between wireframe and full glory with a cherry-on-the-top render?
It's easer than you think. Just render your animation as normal then select your objects (I only know how to do this for polygon objects, sorry) then open the UV Texture Editor and get it as big as you can.
Make sure 'Image' --> 'Display Images' is off and then take a screenshot.
Load it into your favorite paint program, alter the colours how you want. Then save the file.
Then go back into Maya and use this file as your texture. Then render your animation with the new wireframe textures on your objects.
So now you have two pieces of animation, all you have to do now is load then into something like Adobe Preimere and play around with the opacity till you get the desired effect.
