Can you post a screenshot of the button pls?but, I can see the change projection type button.
This button is always deactivate. I can't touch this button.
I doubt this is possible with Octane. It allows for a Visible environment and a Lighting environment, and these can be different texturemaps, but I think you want something else? I don't full understand what you are asking.I want to use 2 environment map.
1 HDR map (projection type light prob)
2 sequential file(projection type camera projection)(live action image).
