Hi,
often I render train interiors. My setup at VfR2 was without dome light or light portals, only basic HDRI environments. It works quite well, some light GI splotches at some places which I manual retouched. For fast high res renderings like 3600x2400 I used LC + IM. The GI AO help me to keep small details like the gaps at wall and ceiling.
Now I ask me, if I jump to VfR4, should I better use an adaptive dome light at VfR4?

Here an example from the official web pages.
