Interior lighting without windows

[mashvega]

Hello Guys!

I have a room that has no natural light input and I cannot light properly. Any ideas you can give me to achieve this?

In the rest of the rooms I do have good lighting.

I used HDRI lighting with portals

What, more exactly, is wrong with the lighting in the screenshots of the scene? It looks mostly, if not completely, alright.

In the bathroom area, the ceiling turns black, I can't light it properly. In the other areas if it is well lit.

I see it. It looks like there's a number of point / spot lights there which could be greater than 4 overlapping. If they're static / stationary, the limit is 4, and beyond that it starts to screw things up...though 1 or more of the 5+ lights would have a red X signifying that it's over the limit.

If it's not the case, how the spot lights are situated in the receptacles appears they could be having their attenuation radius blocked...or the light from them is not enough / not bouncing enough to get the ceiling lit.
