Example here:
I tested the same behavior in C4D 2024.5.1 + Octane 2023.1.1 and there it works perfectly. Each Reload button press promptly refreshes the scene.
Edit: Also tested on other machines with the same version of C4D and Octane I have on my machine (C4D 2025.0.2 + Octane 2024.1-[R3]) and it's also broken and the Reload button won't refresh the Live Viewer.
