Hi Paul,

I wish to have multiple lighting setups in a single scene. I am rendering in Octane using the Daylight Environment Light with the use Texture Environment checked. So this means I can have multiple HDR's in the environment slots and swap between them, that all works fine. The problem seems to occur when I have multiple directional lights, checked as Physical Sun. If I hide (swap) between the directional lights, Octane does not update, it seems to keep the initial physical sun only.

Please see the attached file, it features two lighting setups. On initial opening everyting will be setup correctly. You will have Light and Texture environment B rendering together. If you then swap the hdrs in the environment this also behave as expected. But now try to swap the direction lights, you will see that the Light option B persists and I have not found a way to get option D to work.

So my question, is this expected behaviour?

Thanks.

You need to specify which physical sun for Octane to use by selecting the desired directional light in the Environment Material->Physically Based Daylight->Sun Light combo box.
