RenderStream Layer

This is the Render Engine project or Notch block that will be controlled by the layer. In order for the asset to be visible here, it must be present in the RenderStream projects folder.

Right click on the asset name to open the Asset properties editor:

Asset Properties include:

• Asset Discovery Name: (name of UE folder/project)

• Target Engine: name of the Render Engine

• Engine Settings

• Colour shift: apply color correction to entire asset

• Content Source Machine: The render node that is running the render engine project. This is the machine that the project will be synced from.

• Available: Status indicator displaying if the Asset is available. Not a tick box.

• Channels: displays active channels defined by the CameraActors in your UE project

The Cluster Pool will automatically detect all available machines on the same network. Once detected, you can assign as many machines to the Cluster Pool as needed and inspect each machine in the pool to see network status, IP address, current Streams and available Assets.

Cluster Pool Properties include:

• Render Machines: The list of render nodes that the content will be distributed across

• RenderStream Understudies: backup nodes in case of failover

Please note: Pools should be named as to purpose or the node group assigned. For example, "Cluster" is not as descriptive to its purpose as "Main_Wall_Nodes"

Right click on the name of a machine in the Cluster Pool to edit additional properties related to that machine:

Machine properties include:

• Load Factor: Relative load weight this machine can handle. Weight is relative to other nodes in pool. The workload can be spread evenly across the cluster by the user using a load factor. This allows you to take into account each machine’s spec and assign loads accordingly.

• Online status

• Preferred Synchronisation Adapter: This setting allows you to pick a subnet to use for sync. You should pick something fast - preferably capable of 100Gbps or more.

  Only used to control cluster communication and content syncing; it has no impact on how the streams are communicated to disguise.

• Network Adapters and settings:

  Non-editable list of network adapters available on the node.

  To configure the system for Cluster Rendering, all machines within a Cluster Pool must be on the same subnet;

  If a machine is reporting an unexpected IP address (e.g. loopback address), make sure to select the specific network adapter within the ‘Network’ tab of d3manager.

• Streams: non-editable list of RS output from the node.

• Assets: non-editable list of assets resident on the node.

The Cluster Assigner is where we control the settings for the distribution of the content across all the machines in the Cluster Pool.

Cluster Assigners are used to create definitions as to how channels are delivered from the nodes. You can create as many Cluster Assigners as needed.

Cluster Assigner Properties include:

• Splitting Strategies

• These are used to generate the sub-regions needed for distributing content across a set of render nodes.

• There are 3 types of splitting strategies:

• Tiles - lets Disguise software split up the content as it sees fit to the mapped channels. Note: this splitting strategy DOES NOT work with Mesh Policy.

• Full frame - Sends the entire stream to the mapped channel.

• Manual - splits each Viewport according to user specified instructions. When using the ‘Manual’ splitting strategy, the options for specifying how to split frames can be found within the Advanced workload settings.



In Advanced workflow settings, note that region pos. has a range between 0 and 1. The screenshot shows both regions (pos) set to 0.5. Other property values in this editor also range from 0 to 1.

• Splitting Overlap: The Splitting Overlap option can be used to define a blend region at each split that hides imperfections at the seams

• Padding (Pixels):The Padding option enlarges the rendered area at each split, but does not stream the padded area, cutting off edge artifacts

• Load Weight:‘Load Weight’ allows you to set a priority for the Cluster Assigner. The higher the weight of the assigner, the more machines will be assigned to render the content and thus more splits will be made.

• Transport format:The options to pick between ‘Compressed’ and ‘Uncompressed’ , ‘RGB 4:4:4’, ‘YUV 4:2:2’, and 'YUV 4:2:0', and 8-bit, 10-bit and 12-bit transport bit-depths are available.

• Alpha: The option to enable or disable the Alpha channel on the content is available.

• Scale factor: Scale factor for the resolution.

• Proxy Streams: A compressed stream at a lower quality or resolution used for providing a preview on machines where receiving the full-quality stream is undesirable or impossible.

• Preferred network: Select the adapter to use for video transport on any channel the assigner is associated with.
