Hello, I would like to ask you for help. I have a problem with combination of VRayd Dome HDRI and VRay Portal Lights in the window openings. In one interior scene it causes me a problem with rendering. Light Cache calculation is taking hours. But, when I delete Portal Lights it works fine. Or when I left Portal Lights but change Dome to Sun Light everything works fine as well. Only combination of HDRI Dome + Portal Lights makes problem. This has happened already one time and I changed it to SUN because i didn't find the solution. I normaly have created a lot of interior scenes but 2 times this problems appears.
Anyone who had similar problem?
