Hi and welcome to forum for second time. I just did the comment and your post disappeared and again reappeared with more images... spooky.
 
My comment after quickly viewing your images is you need to up the jaggy as some images are not very smooth, but otherwise not bad.

edit; what is going on with this tread after posting my comment I could see again less images.

thank you for your arguments. last three renders are jaggy and quality
but they are not realistic. how can i make it better?

It is holly grail of all renders. I suggest you work on your textures bit more and see if you could improve lighting. There are lot of posts in knowledge base forum. There is no magic answer. Experiment and experiment more.

I understand that, i have to use more lights. My renders are very dark. And different light source makes the render more fresh i thing.

Okay, some nice images! It looks to me like the bathrooms have been done by someone else though. These images aren't as good as those of the room. To improve things further, first of all turn both quality and jaggy controls up to 100%. 
 
Secondly, add more detail. Things like picture frames standing away from the wall slightly at an angle, like in life. Thicknesses to mats and rugs. Also thickness to glass. Lots of people tend to model glass as a single plane. This works fine for windows, when it is being looked at from a distance, but when you are looking at things close up, like in the bathroom where the scene is very simple, more detail in things like glass thickness and quality of textures is very important.
 
Lighting effects are tricky to get right. They aren't difficult, but there are some tricks to get subtle effects. There should be a tutorial about this subject explaining a little more in the next week or so. A lighting component library is also planned, but only for registered users!
 
Hope this helps.

Yes, thanks bigstick
But i have another problem. I read the tips&tricks forum and made the spot light. But it is not working. like my bedroom. The light spreads 360degree out of the light sourse. I made a model of my spot light and i attach it here. Can anyone fix my spot light?

Okay, I have been playing with this component a lot, and found out some really interesting stuff. I now understand what an omni light is and how it works. 

Basically you have a fundamental problem with the size of your fitting. Small fittings like this leak light out, but the same component scaled up does not suffer from the problem, and works exactly as one would expect.
 
It would appear as if omni lights insert an 'invisible' light source which is a physical size related to the strength of the light. The size of the omni light group does not seem to affect the size of the light source itself.
 
With large fittings, the geometry blocks the light as one would expect. With small fittings the light will leak out, and if they are closer to a surface than the corresponding size of the omni light source, you will get the inaccurate pooling.
 
I have attached some images illustrating this. Each of these shows the different effect of the same fitting scaled up and down. You can see exactly which is the large, medium and small fitting.
 
The solution is to make sure that you don't use fittings which are too small, and if you do have small ones, don't place them too close to walls or ceilings.
 
TBD could potentially fix this for v1.5, but the feature list isn't finalised yet, and no-one is yet sure what it will address.

thanks a lot bigstick.
This render is before you explain the omni light situation.
Now i am rendering new one. I will post after it finishes.

big,
 
thank you for sharing this. now i understand. really thank you very much. frankly i nearly gave up omni and back with LEM ( inspite of long renders) because of this innaccuracy that im always getting. i made some extra large downlight using omni as test and the quality is fantastic but now i could not replicate.
 
attach that very first images i have done with extra large downlights.
 
i think the version i even used in rendering this was before the version 1.4.1 

and the 2nd image was rendered using V1.1. those splotches were obvious right?
 
also i can see those scallops using these huge lights.  
 
after these rendering, i got a lot of frustration with omnis. adding the fact sometimes they disappear. i guess. this is the reason why they disappear too right?

It seems to me that approximately 300mm is a 'safe' size for any light shade or fitting, and even then the strength needs to be turned right down. This size is also the same for the distance to the closest surface. If you use a smaller fitting than this, but it is further than 300mm away, it will work - sort of.

Obviously the smaller the fitting the worse the problem will be. Fittings like the 30mm diameter one that caused the problem are never going to work particularly well.

All this tends to raise some interesting questions though. If you are going to use a fitting this small, it is either going to be a halogen light or an LED one. For these types of light, arguably you are better using a LEM to represent it. The type of effect people are looking for with the pronounced cone of lght is not going to be acheved by this type of bulb anyway.

If I were a betting man, I would put money on the the likelihood of Podium creating a point light source at the centre of the group. As mentioned before, the size of the light source is dependent on the strength of the light. I don't know whether TBD is able to fix the 'size' of the light source, or whether it is set in the render engine. Again f I were to hazard a guess, it would be that the intensity of the light is governed by the size of the source, which is probably determined by the render engine.

If this is the case, negligible chance of a fix I'm afraid...

I haven't experienced lights disappearing yet, and have no idea why it happens.

the lighting is much much better now. you should now increase the render quality and the  jagginees slider (AA).

and maybe you can remove the reflection on the painting. those light refelction bothers me. unless you really wanted it to have glass on that picture. IMHO without reflection is much better.
