I'm betting there is no solution but thought I'd ask anyway. :)
In my latest scene I had a problem when rendering.
In preview I saw my figures and everything else I wanted to see.
But when I rendered it the entire render came out black.
The problem is an easy one that I've had before.
There was a prop or part of a prop in front of the camera, though I didn't see it in preview, it blocked the camera shot.
In the past a solution was to get rid of the prop or make it invisible or even make a special transparency.
Here I did not have that control.
I ended up adjusting my camera view/angle and I also adjusted the focus.
It worked but now I didn't have the view I intended on.
I was using the main camera so I then tried different ones with the same result.
There are many things/controls for the camera I'm still novice about & was wondering if I'm just missing something?
I had thought during this problem it would be cool if I had a wide angle lens. :>)
Any ideas, thoughts or direction is of course most appreciated!
Thanks.
Scott

try the "hither" dial.

This is an unavoidable problem in 3D work, because
we can put cameras in impossible places!
Here's an especially awful example that puzzled me for a long time.
In the upper picture, there's a mysterious zigzag. I couldn't get
rid of the zigzag while still showing the view I wanted. Why?
The lower picture shows that the view I wanted was from inside
the pillar! A real camera couldn't go there, and a real camera
also can't fool us by seeing through an obstacle in Preview
mode but showing it in Render mode.
So the best solution is to do what you'd do in the real world:
move the camera, or get the obstacle out of the scene temporarily.

Reducing hither to a smaller number can help, however, in letting you find these problems in the first place, before reaching render. By taking it down to a number close to zero (or zero itself, if you want), you can then see pretty much what's going to be in the camera for the render view - allowing you to recognise where props might be in the way and so on. Then you can move the camera in front of the problem prop, or make it invisible, or do whatever you decide is necessary for the render to work the way you want it to.

Oh well.
No biggie, I guess.
Many many Thanks!
Everyone :)

You can have the lens angle as wide as you like. Focal length can be set from the cameras Paramiter pallet.
