Hello,
This issue concerns octane 4. I know it is a very old version but maybe octane experts can still help.
I changed my computer recently and the plugin does not work anymore. I use the same graphic card, the same poser version, the same octane version and the same plugin option. Octane standalone works fine but not the poser plugin. The plugin opens normally, but when I start to render the samples/pixel and MSamples/sec values stay at 0/0. I can select the materials in viewport and in the material tree but the viewport stays black. If I export the scene in octane standalone, it works fine. In this example the scene is just the default poser scene.
Thanks for your help

poser plugin version 4.05.097
