Quote - I was able to load a Jack Tomalin set into the Poser Octane demo just now, its the "Casa del Diablo" castle.  I tried to move the lights in Poser to see the changes in realtime but it doesn't do anything, maybe I need to setup something in Octane or the demo is limited this way.

There are 2 lighting models: Daylight and HDRI. In addoition to that you have light emitters. There is a script in the plugin which created light emitters from poser lights. If you want to use those, run the script.

In the daylight model the first infintie light is taken as the sun. You can move that light in Poser and have immediate changes in the render. If you want the emitters to react in the render, you have to enable the automatic refresh. Camera changes are always seen in the render viewport. No need for the automatic refresh

For HDRI lighting the IBL image is taken (if it is available), otherwise plug one in.

Both daylight and HDRI models can work with emitters

Disclaimer: This is what happens in the actual version of the plugin with 1.02 octane. Not sure what version the demo is.

 

I have to go, so any other question will have to be answered later today
