Incorporate revised HDRI Dome in Scene

@AndreiSE
I would like to incorporate a revised HDRI image in a Scene using the existing cameras.
I have altered the horizontal rotation of the revised HDRI (from the existing). There is also an inverse gamma value used, which is not an option in TK.

Can you walk me through the process of incorporating this revised lighting setup?
Or do I need to recreate the cameras and upload a new scene?

Thanks

For Vray, I always recommend that all lighting is imported as a separate model asset, and referenced into the scene. This makes it easy to update just the lighting without impacting the cameras and other scene setup elements.
