HDR Light Studio Connection is compatible with Octane Standalone on Windows only version 3.08.1 and higher.

Notes:

Known Issue:
Error Message when LightPainting on Octane Standalone Render View - says Connection Error.
ORBX scenes exported from Maya with some versions of Octane 2019 and 2020, are not have all the cameras setup correctly with their film settings node linked up. Only the render camera at the time of export appears to have this correctly setup. This can be fixed manually in Octane standalone. It affects our LightPaint system and creates an error message if this is not correctly setup.

Don't touch/move/manipulate the "HDR Light Studio Area Lights" node
If the user creates area lights whilst using Octane, a "HDR Light Studio Area Lights" node is created and placed in the geometry "pipe/pin" of the node graph.
This node is a "container" for all of our area light nodes, effectively containing/hiding them away from the user.
By default it's created as the "first" thing in the geometry pipeline, first step from the render target, whilst the user could manually move this around and reconnect it anywhere in the geometry pipeline, or even disconnect it completely. This could break the area lights, they may not render or start rendering behind things (effectively hiding them) etc. It's strongly recommended that the user doesn't touch/move/manipulate the "HDR Light Studio Area Lights" node at all.

Don't rename area lights inside Octane Standalone
Area lights in Octane cannot be manually renamed (inside Octane), it will break our connection to the area light.
Any renaming of the area light must be done inside HDRLS, the light node name itself also contains our light ID (which we use to link the area lights), if that ID were removed/changed it will break the connection we have to the light.
