Resolution & Film Gate...

[kerim]

Hi,
I wonder what are the differences between these two gate. Please, help me. :)

The Film Gate represents the camera's aperture (camera's attributes). It doesn't represent the render region, i.e when you activate it it's not going to show you the dimensions of the resolution.
The dimensions of the Resolution Gate show the region that's going to get rendered i.e. render view, but it doesn't affect the render like Film Gate does.
Hope that answers your question.

OK, but i didn't understand exactly. :biggrin: Could you give me an example? For example, Where will i use film gate???

[DjVoyager]

Sure. So in the first image I use a sphere on a plane, pretty basic, and used to Resolution Gate to render the region. Now what if I wanted to make a render that would show the sphere from afar. The problem is that I don't want to make my plane bigger, and my camera is all setup nicely as well. So I open up the camera's attributes, tweak the aperture, and also the Film Aspect ratio because these two go hand in hand, and here's what I get (2nd shot).

Essentially they're the same thing, aren't they? Only RG specifies a more exact rendered image than the FG... :)

lol, they're not the same :). RG specifies the dimensions of the actual view that's going to get rendered, if you set the resolution to 720x480 the box is going to resize to that. RG doesn't affect how the view looks. FG does. You've probably seen in movies where the camera zooms in fast on a person's face from afar. That's the camera's aperture and aspect ratio zooming in rather than have the camera move in closer. That means that you can key these attributes. You cannot key the RG. Hope that makes sense.

Thanks for your patience. :p
