Nö sorry - we still don’t know how to compile for Hololens

Hi Alex,

I assume that you followed the troubleshooting steps under

It is always hard to say what the reason for the connection problem is. You should always be able to connect to the server with OPCWatch. If not - if you are using a for free server please tell us the name and send us your server configuration and we will try to reproduce your problems.

I am wondering a little bit about the /... behind the server address ....4840. Can you try without the / and everything behind?

The client is not able to connect to the Server. Please turn firewalls and virus protection off. 

It could be also a security setting in the OPCUA server.

Is the opcua demo server running from Unified Automation working on your PC (

If yes could you please tell us a setup (server and server config) where we can check your problem?

Please also take care to use version 1.022 (it is in your download folder) - on the asset store it is currently under review and should be available today - there was a bug with the new drive handles in version 1.021.

The post-processing stack is available via the package manager:

Please consider the hints concerning assembly definitions after installing the post processing stack:

You need to move the source (can) upwards so that it sits on top of the conveyor. 


first of all I strongly recommend to use Unity 2018.4 instead of 2019. Specially when compiling to the Build with an IL2CPP compiler there might be issues with Unity 2019.

There is something interfering with the demo use cases (need still to check what exactly). 

Please follow these steps:

- Make sure that the compiler defines are set to GAME4AUTOMATION; GAME4AUTOMATION_PROFESSIONAL 

Import while running the OPCUA server the nodes again. If you have enabled with the Compiler defines the full framework it will also create all PLCInputs and Outputs:

If you try now to run it you will get errors:

These errors are because the demo server is limited in subscriptions.

You need to turn off all subscriptions in the OPCUA nodes or you turn it off in the OPCUA interface and import again:

Please also delete the Use Cases completely (we will get rid of the problem with the use cases in the next release).

Now it should work as expected:

You find also the full working model (based on Unity2018.4) in the Uploadfoalder I have send you via mail.
