Help - the picture in my viewport does not match what is rendering!

Worlds_Edge

This is the first time this has happened to me.  I'm rendering a pic of a character smoking.  The render is about 75% done.  However, the window that shows the render shows a very different pic.  He's suddenly got no hair and everything looks watery or latexy or something.  Any idea what I did wrong?

Have you got an Auxilliary viewport active? Is it using a different camera or Perspective view? Render assumes you want to use whichever viewport was active at the time - I occasionally get a surprise by using the Auxilliary to fiddle with a pose or character position then forget to click back on the main viewport before rendering. I'm not sure why this would affect the hair but the shiny bits may be from a camera/view with a headlamp active.

I've seen strange stuff like hair disappearing when looking through glass (e.g., window). However, it's usually on the texture shaded view. I've also seen overly-glossy surfaces when using non-Iray surface materials on an Iray render. Finally I've seen strange stuff when the camera/angle is partly buried in some object.

I doubt it's any of these things but figured I'd toss out some ideas.

Yeah, I'm thinking along the lines of Toonces. Possibly you have 3Delight materials (or Poser), maybe even custom 3Delight shader mixer surfaces in there and are rendering in Iray? Could you please select one of the background terrain objects in the scene and show a screen shot of the surfaces tab? Also, what sort of lights are you using? Are his eyes closed, or did we also lose the eye texture? No clue about the hair because that is strange.

For the hair... check the refraction serrings.  It's one of the few things in Iray where I've had something dissapear in the render that was visible in the viewport.

Well, all I can say is at least you have most of your scene.  I currently have a scene that renders with nothing in it despite it having hundreds of objects in it lol.  Check your visible in render option in the Parameters Display area on the missing parts (via a suggestion from Barbult on my issue).
