Hello and thanks again for this great article.
I have a quick question about "One solution could be adding some skylight portals" :
please how can you setup a VRayLight "portal" when your main light is a HDRI in a domelight ?
Everytime I try to add a VRayLight "portal" in a scene lit by a HDRI in a domelight, it does NOT change the render at all (it's like the portal is turned off).
Portals with Sun&Sky setup work in 1 clic, but with HDRI domelight setup it doesn't at all (?).
Anyways, just currious how we can practicaly have HDRI + Portals :)
Thank you again and keep up the great work, regards.
