How-To Unreal 5

How to configure Unreal 5 for XR with SMODE

!!! It only works with the DisplayPort FLEX Deltacast Card and Blackmagic Decklink !!!
You should use Smode 9.4 and Unreal 5.2
For the calibration with a decentralized setup you need to do a Smode Net Remote control a server, Make multiple servers render together, Work with multiple people on the same project Read More so each node can output its own tags

General settings

Here are the general parameters that apply to the different configurations, centralized and decentralized:

In Camera VFX

Having prior experience with an InCameraVFX Unreal project is highly recommended.
Please refer to the Unreal Engine documentation regarding this topic: https://docs.unrealengine.com/en-US/WorkingWithMedia/InCameraVFX/InCameraVFXOverview/
You don't need any tracking to be integrated within Unreal; Smode manages the tracking system.

It is recommended to start with the 'InCameraVFX' sample project. This project template provides most of the necessary settings and plugins for in-camera VFX workflows.

Unreal Plugins

When you acquire an XR license, you will receive a link to download the Smode plugin. Copy this plugin into the "plugins" folder of your Unreal project. If this folder doesn't exist, create one. Alternatively, you can copy the Smode plugin into the engine's "plugins" folder.
In Unreal 'Plugins' tab [Edit -> Plugins], enable the plugins Smode , nDisplay , and ICVFX .

Unreal Projects Settings

In Unreal 'Project Settings' tab [Edit -> Project Settings]:
  • Check that nDisplay is enabled.
  • In Smode Link Settings , change the 'Smode Ip' to the IP address of the server where Smode will be running.
  • Change the Game Instance Class to 'SmodeGameInstance'.
  • Change the parameter Enable alpha channel support in post processing to 'Allow through tonemapper'. This adjustment is necessary to utilize various keying methods for Augmented Reality elements.
  • At this point, it is necessary to restart Unreal Engine to apply the new settings.

Setup your Map

In the Content Browser , in 'Plugins' -> 'Smode Content', drag and drop the 'BP_SmodeRig' Map.
If you don't see the 'Plugins' folder, check 'Show Plugin Content' in the Control Browser's Settings.

In the SmodeRig, select your 'CineCameraActor' use by the nDisplay configuration in the Cine Camera parameter.

The Smode actor and nDisplay need to be located into your persistent level.

Setup Topology

There are several ways to achieve XR, and various system configurations are possible. Smode is highly adaptable and not bound to a particular system. It's possible to tailor a system to match the requirements and scale of the studio.
Please get in contact with us to discuss which XR system configuration is best for your specific use case.
Here are some examples of basic Topologies:

Simple centralized setup

This setup enables Set Extension and AR:

Dual centralized setup

This setup enables Set Extension and several AR elements:

Decentralized setup

This setup enables Set Extension and several AR elements, and the LED screen has a dedicated Unreal server:
