Okay, let's recap on one point I made previously - Don't use the interior bright unless you know you will need it. You shouldn't need it here.

Don't use the skydomes from the Browser. These are in effect obsolete. This is not IBL, it's a 360 degree background - not the same thing at all.

They are an image that is placed between the sun and the scene, and they reduce the overall lighting levels. They are only for exteriors and when they are used, you need to increase sun intensity and exposure to compensate for the fact that the skydome obstructs the sky.

Get rid of the skydome and rerender because it's ruining your lighting. If you look at your photo, you can see that actually you can't see the sky texture - it just looks plain white.

Start with the interior default preset -  always start with the interior default preset [smile]

You are over-complicating things unnecessarily, which means that you are fighting the engine.

Start simple, change one thing at a time. Don't add anything unless you think you need it.

Thank you! Wax in wax out, got it.

Will start with the default. I was following tips I read earlier that hdr should be used with AA settings because of noise.

I didn't use a skydome however, I used an overcast hdr texture which I downloaded from the podium browser and turned shadows off. But for your suggestion to start with basic, I went back to physical sky 1 on 50/50.

You are right

I checked the overcast background image, and it is a skydome.

Physical sky only works when shadows are on.

You are getting confused between HDR and IBL. You only need interior fine with IBL backgrounds. The reason for this is that they are grainy, and the interior fine AA presets smooth textures and do a pretty good job of eliminating the graininess.

Next thing to try is using curves in PP to tweak the lighting. Then try increasing the exposure and sun intensity. Then try curves again, then try an LEM outside the window, then curves agai.

If this seems like a lot of messing around and trial and error - it is, but that’s how you learn. [smile]

Eventually you will learn what you need to configure to get the subtle natural reasults you want. Podium makes the manual process easier, but doesn’t replace the thinking [wink]

Aha, that's what got me confused, hdr and ibl and actually, I should read into hdr as a whole. Since I don't quite understand the fundamentals and don't even recognize the preview button in the tutorial here https://www.suplugins.com/v26/hdri-interface.php or know where to find it in Sketchup.

Will let that rest for now except for this most likely foolish question: so the hdr background are actually skydomes?

For the rest, I think I will manage with the basics in this scene, thanks again.

No, the Overcast01.hdr option that you used from Podium Browser is part of the HDR image-based lighting system, and definitely not a skydome. 

You were correct to use the interior fine preset for that first bathroom render -- I can see from the noise in the image that it is indeed lit by IBL.

Okay - now I'm confused [smile]

The only backgrounds I can see in the Browser are these:

None are IBL backgrounds. The only one labelled 'overcast' is in the Cloud domes section.  What am I missing?

That's nice, I am no longer alone 😉

I
 just followed the manual in importing more textures as there was no overcast one available by default.

Ah - thanks - we've had internal discussions about categorisation!
