The "camera space render" setting I am referring to is described this way in the redshift documentation:
...when you enable this, Redshift moves the scene around the camera to maintain high numerical precision. When a scene has large extents (for example a space battle scene), precision problems might appear far away from the scene origin, i.e. the (0, 0, 0) coordinate. These precision problems might look like triangles being warped, lighting leaking through geometry, or gaps appearing between polygons. Enabling the “Camera Space Render” option eliminates this type of issue.
There is an equivalent setting in Arnold called "offset origin".
This feature has been a life-saver on one project I've worked on and I am very much hoping to find it's equivalent in karma. Please let me know if you know of such.
