Like I was doing a project inside Maya for the first time & I was rendering a scene. I saw Arnold having two options
1.perspectiveShape (means it enders from your view point)
2. Shotcamshape ( rendering from the fixed camera position)
I was kind of surprised, it means I can keep my camera for my entire scene & then if I want to render a specific part of the scene I can do that without changing the camera position & in some cases it is pretty convenient.
I dunno, I don’t really use it. Worth a try
I think, though, you’ll be better off changing your paradigm slightly and using the Stored Views addon (which comes bundled with Blender), which lets you turn any number of viewport views into cameras and switch between them with one click
Viewport rendering renders a viewable screen.
It is similar to screen capture.
Of course, it will be rendered to the desired resolution.
A camera is required to use the rendering engine in the blender.
However, viewport rendering can be rendered without a camera.
If you want to render using a rendering engine, use Addon, which allows you to install multiple cameras and manage them.
This Addon is for camera management. (Free)
It works, but it hasn’t been managed for a long time, so some features are problematic.
This is not related to rendering quality.
Add…
The method of installing the camera on the desired view screen is Alt+C key.
The way to set the existing camera to the view you are currently viewing is Ctrl+Alt+ numeric keypad 0 after selecting the camera from the outliner.
