Region Render

[ovni1]

Is there a way to set part of the camera view to render(only an area of the image).

 

Thanks in advance for any assistance.

Use the Render Lock Mode and drag a rectangle around the area to render while holding down the right mouse button.

Shortcut....

Press Q to enter in render mode then using right button mouse drag the rectangle around the area

or...

press SHIFT+Q to lock render mode ... so you can make adjustments while render is automatically updated.

 

Both methods works in any view ( CHO / Objects / Action )

Will this work for final render of a movie or sequence?

No

 

I just tried rendering a sequence, and found that out. It would be nice to be able to render just area of the camera view to a movie or sequence.

 

Thanks for the help!

You can render elements separately and then composite them together...I'm not sure exactly what you're trying to do.

Depending on your goals one way to render another region of the same shot is to duplicate the Camera and then Zoom In/Focus on another area of the same shot.

If the goal is to align the shots later care must be taken to make sure you don't change the angle of the camera.

Once the Cameras are setup you can switch back and forth between them as necessary without adjusting either Camera.

 

I've never tried it before but we should be able to adjust the Camera in a Pose.

If that is the case then we are then able to use the Pose Sliders to render variable areas within the main camera region.

 

A:M is extensible enough that many tools we need we can create.

Attached is a shot of two images rendered from two Cameras.

Both are rendered to Final Rendering and then re-composited as Patch Images in A:M. (then rendered again)

I am trying to cut down render times by rendering the areas of the image that do not change only once(single image), then rendering the region where there is movement or action(movie or sequence) and composite in After FX. I'll give your suggestion a try. BTW it's an old habit from using Imagine on the Amiga.

Usually each scene has to be analyzed to figure out the best method for cutting down on rendering time, and in preparation for compositing later.

 

If your camera doesn't move, then you can render the background once, and in A:M use that Image as a rotoscope projected onto the ground plane. Or you can use it in Aftereffects for compositing.

 

You can render the characters separately (without background) by turning alpha buffer ON. Only those models that are active (including ground plane if active) will be in the alpha buffer and you can composite later. And most likely you will also have to render a shadow pass for the characters as well, if you plan on compositing in AE.

 

I forget the method to do a shadow buffer pass, but it's there. I forget if you set something in the model(s) casting the shadow, or the model(s) that are receiving the shadows
