I can confirm that issue. I too have this from time to time. Still could not figure out when or why this happen. It just looks like it is stuck in loading the scene. I think one workaround was to reapply the GPU cards in the system settings.
With the new update now the octane tab disappear when deselecting the Octane tab. Thanks for the fixes, great work!
EDIT: Also Octane cannot be added via right click on the tabs -> add pane (tab) only via menu.
Hi, I would like to participate the beta test, I am an experienced user of Poser as well as with Octane. I use Poser now since more then 5 years and use Octane frequently.
