Overview

A camera in the scene: position/rotation plus film-back (focal, aperture). Render3D renders through it; the viewport shows its frustum.

How to

How-to

Set focal and the film back (aperture_h / aperture_v), then the transform.
Render3D renders through the camera named in its camera knob; the viewport draws the frustum.
A CameraTracker's solve bakes to a Camera3D-compatible pose you can name directly.

Parameters

Parameter	Type	Default	What it does
tx	Float	0.0	Translate X — position along the world X axis, metres.
ty	Float	0.0	Translate Y — position along the world Y axis (up), metres.
tz	Float	0.0	Translate Z — position along the world Z axis, metres. The camera looks down −Z.
rx	Float	0.0	Rotate around X, degrees.
ry	Float	0.0	Rotate around Y (turntable), degrees.
rz	Float	0.0	Rotate around Z (roll), degrees.
sx	Float	1.0	Scale along X. 1 = unchanged.
sy	Float	1.0	Scale along Y.
sz	Float	1.0	Scale along Z.
focal	Float	35.0	Focal length in millimetres. Longer = narrower view.
aperture_h	Float	36.0	Sensor width in millimetres (36 = full-frame). With focal, sets the horizontal field of view.
aperture_v	Float	24.0	Sensor height in millimetres (24 = full-frame).
near	Float	0.1	Near clip distance in metres — geometry closer than this vanishes.
far	Float	1000000.0	Far clip distance in metres.
ue_actor	Text		The Unreal actor this camera is linked to (its path), when the bridge is live — moving either moves both. Empty = not linked.
disabled	Bool	false	Bypass: the node passes its first input through untouched (D in the graph). The knobs keep their values for when it comes back.
label	Text		A note shown under the node in the graph — what this node is FOR. Never affects the render or the cache.
hide_input	Bool	false	Draw the node without its input wire — a tidy graph for a node whose source is obvious (a Dot, a viewer tap).
