You are using Unity2020. We always only support the latest Unity Long Term Stable release (LTS). For more information please check here: https://forum.game4automation.com/knowledge-bases/2/articles/203-game4automation-with-newest-unity-releases.

Maybe your new server does not support subscriptions or is configured for subscriptions.Worst case you might need to poll the signals.

If you changed the RoboDK pathes I don't know why it not opens. The code is always just using this path. Is your path somehow uncommon with special characters or empty spaces?

You might need to set some breakpoints in RoboDKInterface.cs and check what is going wrong. If you don't find the issue we should do a Zoom Session and I will check on your computer.

So when you open the project on the new PC you get these white messages. This is not an error and we can ignore it.

When does the log with the Old PC Path comes up. When you start the RobotDK example project on the new PC. Normally this could not happen because on your new PC the Unity Log should not show log messages with the Old PC pathes. It does not seems to be a RoboDK specific issue. 

How did you transferred the project to the new PC?  Did you copied the full project folder. If yes usually you should delete Unitys Library Folder before opening on the new PC.

If this is the case try to increase the ReducedMaxPduLength.

The Value NegotiatedPdLuLength - ReducedPDuLength is used for the maximum length of the communication pdu. 

If you don't succeed please send us your S7 project including your G4A Project.

Please  follow https://forum.game4automation.com/de/knowledge-bases/2/articles/191-sending-us-your-game4automation-project-for-support for information how to send us the project.

There are errors in your console log. Please send the full log.

Sorry we can't tell you what is wrong based on this rough information. It could be your Unity Configuration or the OPC Server configuration .....

To be able to check it we would need an example based on an OPCServer we can test with.

Please try to rebuild your problem based on UaCPP C++ Demo server (will send you a download link for this test server in a private message later).

Please upload your project where you can reproduce your problem based on UaCPP Demo server here:  https://game4automation.com/send 

We are preparing a new release for end of next week and it is planned to fix this.

Please try to change OPCUA_Node.cs like this (about line 364):

We already changed that for the next relaease.

Hmmm... does it directly happens when you open the project on the new PC or only if you start the simulation?

We just implemented a new upload service.
