Rendering check
Active Single Camera Exists
Checks that the scene contains a Camera object, has an active render camera assigned, and that the active camera is enabled for rendering. When Require Single Camera is enabled, the scene must contain exactly one Camera object.
Why this check exists
Ensures renders use a deliberate, enabled viewpoint and prevents missing or unintended camera output.

required

bool | True |
If enabled, the check fails when more than one Camera object exists in the scene.
Disable this if your project intentionally uses multiple cameras. Does not affect
the 'no camera exists' or 'no active camera' checks, which
always apply regardless of this setting.
