Well, I had a little time to troubleshoot the problem by reinstalling the latest classic stable version (Blender + the server), and the issue remains.

However, the add-on version (in beta) has no problems.

I'm going to use the beta version, which works for me. But this is just to point out the ...

Well, I uninstalled everything from Octane/Otoy, deleted everything I could find in the registry related to Octane and I relaunched a clean installation of Blender (official version 4.5.1 from the Blender.org site) and the Octane server.

I used the add-on version (in beta testing), not the ...

My advice is to keep it turned off while doing serious work.


Thank you for your reply.

But in this case, how can I ...

Hello,

I'm having a problem with the latest version of Blender Octane (2025.2.1 - 30.6.2). To better explain it, I'll use a simple example. First, I'll explain the scenario that's causing this problem.
