Yes I understand but the used Library gives us no direct information about disconnection events. And I don't know exactly in your case who is closing the communication when nothing happens - is it the client or the server. I am closing this issue because for the moment we don't have a better solution.

Uder which system is your Unity editor running?

The interface is only able to detect a disconnection if

StatusCode.BadConnectionClosed

is given back on a read value.

It might be a good idea to read one value in a periodical way and to test if the connection breaks in this situation.

It could be solved easily and will be part of the next release. I will send you in a private message an update package.

Hi, is your issue solved?

The reason behind this issue is the utilization of the 3mf library, which combines the vertices into a single entity. Consequently, the normals are affected, leading to the current appearance. We intend to examine our RecalculateNormal code, which presently merges vertices without distinguishing them, in order to address this matter. Meanwhile, if you require a more aesthetically pleasing result, it is advisable to utilize the Step Importer. We will ensure to provide you with updates as soon as we arrive at a resolution.

We don't have Python - can you provide your test application as an installable executable?

See my answer to your second post.

I don't know exactly what you mean with Asyncua. Do you have a server setup and a demo server where we can test the issues you are facing?

It is fixed in realvirtual Professional 2021.19 and 2022.02 and above.
