Version: Reality 5.4 SP1

Frequently Asked Questions

What is Base Camp bundle?

Base Camp is a special bundle that comes with a customized licensing scheme. For more details, please contact to our Licensing Department.

You can think of it as a background solution that integrates all your designs behind talent, which is positioned in the foreground.

In the Base Camp studio setup, due to the nature of the bundle, no objects in front of the talent will be rendered, regardless of whether these objects are translucent or completely solid.

To set up Base Camp correctly, follow these steps:

Launch your project with Reality Editor.
Navigate to Edit > Project Settings.
Go to Rendering > Postprocessing.
Find the "Enable alpha channel support in post processing (experimental)" property and select "Disabled."
Save all changes.

Switch to the Reality Hub web interface.

Launch your project via the Launcher module.
Select the UE5 node.
In the Node Details Panel, choose UE5.
Navigate to Reality Actors > Reality Camera > Fly Offset > Video Camera > Reality Mask.
Go to Properties section.
Disable the Render Reality Mask and Reality Video Projection DOFByPass properties.

Your Base Camp setup is ready.

I received a red warning text over a tracking node says High Network Jitter (>5 ms)

If the time between each tracking data packet arrival exceeds 5 milliseconds, the tracking node displays a warning. In such scenarios, it is highly recommended to check your tracking network. It would also be helpful to observe the Timing Jitter and Maximum Timing Jitter properties of the tracking node.

What is the purpose of NeverStarve property in track nodes?

The NeverStarve property in track node ensures it won't suffer from resource starvation, meaning it won't be perpetually denied necessary resources to process its work.

I observe loss of details in bright areas.

In Reality version 5.4, the default value for the Render Display Output has been changed from DOF_SDR_sRGB to DOF_HDR_LinearWithToneCurve. This change addresses a previously observed conflict where color differences occurred between the Editor and Play modes.

With the new default setting (DOF_HDR_LinearWithToneCurve), the scene's tone is controlled by the ToneMapper within the PostProcess volume.

However, if you prefer to use Reality nodes for scene color correction and tone mapping, we recommend switching the Render Display Output to DOF_HDR_LinearEXR.

This approach bypasses tone mapping effects from the PostProcess volume, thus preventing potential overexposure and loss of detail in bright areas.

Selecting the DOF_HDR_LinearWithToneCurve property does not carry gamma values over the given range. In such a scenario, using the ColorCorrection node may lead to unwanted results.

To overcome this, we recommend selecting DOF_HDR_LinearEXR in your pipeline, which has the full GammaRange without ToneMapper, and then using an additional ColorCorrection node.

What is Process Node?

Process nodes are special nodes serves as a functional unit responsible for processing data and performing operations on input values to generate desired outputs. To set an example, UE5 node is a process node.

Is it possible to play an image sequence with the Read Video node?

Why my version number is red?

When the frontend version differs from the backend version, version number turns red color. In such a scenario we recommend you update Reality Loader and refresh the Reality Hub UI.

Unreal Engine Vanilla 5.3, 5.4, and 5.4.1.

I defined the Shared Folder Path, Username, and Password, but I can’t reach my project, and ReScan operation fails.

Check if the folder structure or folder name has changed.

If the abovementioned step does not help:

Check if your Windows username is under a corporate domain. Example: CORP\name.surname

If it doesn’t help:

Check if you have administrative privileges to reach your shared folder.

See Project Configuration

What is the meaning of the “Please match the requested format” when I try to add New Shared Folder?

For a Shared Folder, only the UNC Path is supported. If you try to add a Local Path name, you will be asked to write the requested format.

UNC Path Example: \\127.0.0.1\RealityWorkspace\Reality\Assets
Local Path Example: C:\RealityWorkspace\Reality\Assets

Can I install different applications on the Reality Hub Server?

We strongly advise you not to install any application on the Reality Hub server; it might cause substantial problems.

To set an example, the application you installed might try to use one of the Ports dedicated to Reality Hub and disrupt your communication with your production pipeline. It is untested, uncertified, and inadvisable.

I can’t see my project in the Launcher.

In such cases, you need to scan the folder where you keep your Projects by using the Scan Folder tool.

Is it possible to grant single module access to a specific user or user group?

With the Advanced User Management module, you can restrict/grant access to different modules/features.

I upgraded the Reality Hub from 1.1.x to 1.5, and now I can’t reach any module except for User Management and Configuration modules.

With version 1.3, we introduced a new module for user management. The new User Management Module offers two different models: Advanced User Management and Basic User Management. We advise you to create an administrator account and leave the admin for only essential administrative purposes.

For more information, please visit User Management

I can’t access a specific module, like Nodegraph/Actions.

If your company uses Advanced User Management, contact your system admin if your Policy allows you to use a specific module.
Check if the License is reserved for other users. See License Reservation
If you meet the above requirements, refresh the page.
If it doesn’t help, restart the Reality Hub Service.

If the abovementioned steps don’t help, please get in touch with our Support Department.

Can I reach Reality Hub Server via a supported browser but from different operating systems like Ubuntu or macOS?

If you can't obtain a viable result:

Check if the Reality Hub admin has logged you out from the system via Force Logout. See also User Management

If you can't find your solution in the abovementioned steps, please contact our Support Department

Can I change the values of identical nodes located inside multiple Engines?

You can utilize Gang Mode for this purpose. It is a handy feature when conducting Graph/RGraph operations over multiple-engine configurations.

Can antivirus software affect Reality Hub?

We do strongly recommend you give full exception to Reality Hub independently of your security toolset.

Would it be a problem if I used the certified Microsoft Windows version with a different language pack?

For Reality Hub Server, only English (United States) is tested and certified. Using other languages may negatively affect the functionality of the Reality Hub Server side.

What is the meaning of "RGraph history is not tracked in live mode"

When your Launch Configuration is set to Live, RGraph history entries are not tracked. To activate the RGraph History, make sure that you change the Launch Mode from Live to Configuration.
