I found that case of shutdown Poser on another machine, License accepted.
License of Octane for Poser is authorized at Poser Start Up ?
It is very inconvenience, because I must consider about start up sequence of Poser with Octane Render.
I offen switch rendering machine and posing machine, because Ocnate dose not support Poser Rendering Queue.
I am unclear from you comments if the plugin is working or not for you now. If you have ONE Poser plugin license and ONE Octane Standalone license, you cannot run the Poser plugin on one PC whilst Octane Standalone is running on another PC - you would need to log out of Octane Standalone on the other PC before you could run the Poser plugin on the first PC. This is actually more flexible than the original licensing where you would need to de-authenticate prior to switching a license between PC's.
