Connection with hololens 2
is it possible to use the hololens 2, robo dk and realvirtual.io, so that I can manipulate the robot in augmented reality using the glasses (using my hands to move the robot or use gestures)?

Subscription not working
Hello, we found some problem using the subscription method. Initially we used the polling method (not recommended), but eventually we found out that this starts failing when we try to capture values from different servers at the same time.
Here is the project attached with some debug lines added. We are using Integration Objects OPC UA server to test the subscription.

Errors after Realvirtual.io update to the latest version (2021.16)
Hi,
after updating to the latest Realvirtual.io version, I get the following errors in my project:
Can you help fixing them?
EDIT: I already fixed it (deleted old "recorder.cs")!

Please delete the Recorder.cs script in the game4automation folder. This functionality has been replaced by the script DrivesRecorder.cs. With
an update of an existing project, obsolete scripts are not automatically deleted. We will check here whether we can automate this.

OPCUA_Interface with Kepserverex Windows 11 communication issue
Dear all,
I experienced a problem when connecting with Kepserverex OPCUA server through OPCUA_Interface in windows 11.
When I specify the IP address in the OPCUA_Interface, the following error appears:
Looks like the problem is in line 133 of the OPCUA_Interface script:
IPAddress ipAddress = Dns.GetHostEntry (ServerIP).AddressList[0];
If I remove this instruction, then the communication seems to be established.
This issue doesn't happen when running the same version of Keperverex and Project Unity in Windows 10.
Have any one experienced this issue?
Thank you in advance!

Interface Siemens SIMIT (PRO) to UNITY
Hello Thomas,
I would like to set up a connection from Unity to Simit via the "Siemens Simit (PRO)" interface. I downloaded the files from Siemens and installed according to the documentation. Then I tried to connect the whole thing to the realvirtual.io interface. The connection was also successful. According to the realvirtual.io documentation, the signals to be exchanged should be attached to the interface as "children". Now to the problem: Simit does not get the signals from Unity i have attached. Could you see where the Problem is?
Thanks a lot for your help

Meshes disappearing when making prefab
Hello,
When i'm making a prefab using an imported STEP using the cadlink tool the meshes disappear. Did I forget a setting and how to fix this? I had the "Set and Create Materials" enabled.

Hi,
you need to export the imported STEP data as FBX. This will save the meshes permanently. With this FBX you can create a prefab with real-virtual components. The FBX exporter is available in the package manager.

Relationship between the number of points of parameters managed by the OPCUA server and the communication cycle.
When the number of parameters managed by the OPCUA server is increased (from 30 to 120),
The values are being sent in bits and pieces.
Does the frequency of communication decrease in proportion to the number of parameters?

Yes the performance should go down. It also depend on the subscription parameters and server settings, e.g. how often updates are sent. If there are many parameters which are changing very fast it might make sense to poll the variables instead of subscribing to them. But all depends on the application you are building.
