This course will look at the fundamentals of rendering in Arnold. We'll go through the different light types available, cameras, shaders, Arnold's render settings and finally how to split an image into render passes (AOV's), before we then reassemble it i

Well I don't know what the hell is going on in the first image lol, I don't recall ever seeing that before, plus I don't even know how you went about lighting the scene in the first place.

That second image strikes me as odd because it seems you have physical sky enabled yet you have no indirect illumination going on, maybe you turned off FG and for the interior, slap some portal lights over the windows, I'm sure that will help a lot.

Hey mirek, haven't seen you on here in a while, its all good, I should be in bed but its all good lol. And I mentioned portal lights because he was asking about getting the inside illuminated even though its an exterior shot (well that's how I understood it anyways :p)

if you dont want an object to reflect, turn off refections in the render stats in the AE or turn them down in the AE material editor tab.

the physical sun mimics the time of day.., i forget the name of parameter.., look for time or something in the AE and play wthe the parameters, its a fast render,.., it very easy when you know how.., sorry getting late here, going to bed.

See, thats the thing about the physical sky, it washes out the textures if you don't have gamma correct nodes plugged into them (btw the ground texture seems a bit large, making the building look like a miniature) or maybe changing the gamma on the lens shader will do, personally I prefer the gamma nodes + photographic lens shader.

Well, I'd run those file textures through gamma correction nodes, connect the texture to the value, change the gamma to .454 and plug the gamma node to the shader's color. that could help alleviate some of that washed out appearance.

Portal lights are just Maya area lights that are sized and positioned into your doorways/windows/whatever and they have MR portal lights plugged into them. Tweak away.

Keep the FG accuracy within reason (personally I don't like going over 400 >.>) and increase the point interpolation, one secondary bounce is good I think, you can probably use that optimize for animation feature as well. An AO pass would be good too.
