Render, feature and custom groups - AR, VS, AR+VS, XR

Adding a tag to a machine adds it to that specific group. Groups can be used to

force specific render or feature behaviour
OR to be able to address them collectively

Render groups

Render groups are a way to define which objects of a level, the machines should render and how they are composited.

Render groups are set in the Machines panel. Learn more about how to Configure machines

Adding a machine to a Render group will set and lock the Compositing Type in the Editor > Pixotope World Settings > General for every launched level.

For example: With render groups one can launch the same level on the XR as well as the set extension machines as the compositing type (AR, XR) is controlled by the machine’s render group.

A machine can only be part of a single render group.

Defined engine settings

	AR	VS	AR+VS	XR
Compositing type	AR	VS	AR+VS	XR
Use camera video and tracking	on the backplate	on an internal compositing plane	both	on XR walls
Renders XR walls	No	No	No	Yes
Renders holdouts	Yes	Yes	Yes	No

Render groups can also be used for fast selection of multiple machines. Same as other groups, see below.

Feature groups

CG

Indicates that the engine output is set to a CG channel.

Learn more about Using Pixotope CG

MultiCamPreview

Indicates to the engine that previews are rendered/outputted for multiple camera inputs.

Learn more about how to Configure multi-camera preview

NoDelay

When using a separate machine to render AR/foreground elements, that machine should not use the Set extension delay.

Learn more about calibrating delays for XR with virtual set extension and a separate AR/VS machine

Custom groups

Custom groups can be created and used for the fast selection of a group of machines. They do not have any influence on the engine. A machine can be part of one or more custom groups.
