Hi Everyone,

So this is my first "serious" render, where I am taking pains to try to get as good of a result as I can. I know there are still improvements to be made, but I'm going to take a break from this one now.
Please let me know if you have any feedback.

I have had some issues with some of the reflective surfaces, you will see some grain on the counter and tile wall. Even with QMC settings. Of course taking Bigstick's advice on another thread I started with the defaults and worked my way up, but I was getting pretty bad results on the tile wall especially where it meets the counter and the dark wood shelves. So I kept bumping it up until I reached the QMC presets, which aside from the graininess I am pretty happy with.
You can also see with the nigh time render I have an orange reflection in the upper left corner, not sure where this came from...

I know that the stainless texture needs work, I wasn't happy with the original, changed it and now I'm not so happy with this one either, but I will wait to go back to that.
I live in NYC so tiny kitchens are common, I based this design on a real floorplan but the design is mine. I'm not a kitchen designer, as you can see, and my wife has pointed out some glaring design flaws that I was embarassed to have missed!

Here are the images, only edited to crop and very slight levels adjustment:

Not bad at all!

1. Turn caustics off. You don't need this. It is increasing your render time and making speckles in your renders.
2. In the daytime renders, turn the lights off - the light over the sink right next to the window in particular [wink]
3. Download Roundcorner and use it on your worktops
4. Add some more blurred reflection to those worktops
5. You need to either adjust the settings of the stainless steel texture on the extract hood, or use a different texture. Something is not quite right there...

Thanks for the tips Bigstick!

I will take your advice and post up the results. Thanks!

OK, I have made the adjustments you recommended Bigstick here are the results:

apt_render_PD_Recs2_day2.jpg 

apt_render_PD_Recs2_night1.jpg 

apt_render_PD_Recs2_night2_pp.jpg 

I'm pretty happy with the daylight one, I feel like it's almost there, I do plan on putting in a background out the window (and I remembered to turn the lights off this time  [biggrin]  ).

As you can see the night one is giving me troubles. I went with the interior default setting, no caustics and no soft omnis (As I found this blew out the whites too much) but I still got a few weird artifacts especially where the wall meets the worktop on the left, perhaps due to all the glass on the shelves? So I decided to try QMC, which did indeed get rid of the artifacts but gave a very grainy result. I might do one more pass if anyone has any recommendations, with the background in the daytime render. 
I'm also open to any other feedback, I would like to get together a good collection of samples, different spaces, different products, projects etc.

Thanks again!

Hi exhibitions, I'd recommend trying Interior_High instead of QMC. 

The "High" presets are very good at fixing sampling issues but don't introduce noise.  It's certainly slower than default but shouldn't be any slower than QMC, and I think it'll give you the cleanest result for this scene.

This is looking nice!

Ah, yes, thank you Justin, that was actually my next guess, and I set it to render before I left work, as you can see it came out much better! This is straight out of the engine, no post so it could use a little polishing, but I am pretty happy with it!
Thanks for all the help Bigstick and Justin!

Much better! I can see the rounded corners straight away. Look how much more realistic the subtle edge reflections on the countertop are [smile]

Try using the glass settings from the glass bowl on the cake stand. This glass doesn't look quite right to me. There will be both an interior and an exterior surface to be transferred.

Also - check the reflection setting on the paintwork on your window. Looks a bit too glossy to me. You probably don't need a value higher than 12, but anything between 5 & 12 should be about right.

Thanks Bigstick!

I actually have applied the glass texture to the cake stand, and I agree it does look a little strange. I have attached the model here if anyone wants to take a look at it and see if I missed something. I have gone back into it several times to see if I missed part of the original texture or something. It almost looks like the glass of the dome is too thick, but I'm not sure if this is a direct reflection of the model thickness or a result of the texture settings.

I may do another render with the reduced reflection on the windows (you are right, it is at 15 now) but I'll wait to see if anyone has any feedback on the cake stand.

You need to use the SU eyedropper tool to sample the interior and exterior glass surfaces from the glass bowl to the cake stand.

Sorry Bigstick, I wasn't clear, I have already done this, in fact, I have replaced all the glass in the items on the shelves.

Did you sample the material from the internal faces of the glass bowl? This is critical.

For the outer-facing surfaces, you need to use D0/T90/R10 with refraction. For the inner-facing surfaces, it's D0/R0/T100 with the same refraction value.

However you cannot create realistic glass like in the bowl at the moment using the current Materials dialog!

We were working on implementing fresnel reflections and we had problems which broke the advanced glass material. It was proving too time-consuming to address at a time when we had lots of more important things to work on. We reverted to the previous working version.

However - the settings we applied to glass with the development version we had before it broke, work beautifully. You can transfer the material properties and they work as they ought, but bizarrely - cannot be created from scratch.

This is why you need to transfer both the inner and outer faces from the bowl.

Hi Bigstick, I did indeed transfer the inner and outer glass materials directly from the bowl. The cake plate is fairly complex though and I thought I may have missed some of the original surfaces but when I purged the materials the old glass was gone.
I will go back and re-do it from the original podium model to make sure I didn't miss anything and let you know how it goes.

Also for Jeff, I redownloaded the knife set and I'm still getting the same result. I think it looks strange because the blade material is a chrome and the knives to the left of the clever are actually resting at a slight angle because of their blades and are picking up the reflection from the dark corner. I may try another metal texture and see how that works.

Thanks for the tips, I aspire to make a beautiful rendering some day!

Sorry for the double post but I wanted to upload this separately rather than edit my last entry in case a moderator wants to split this into another topic.

Here is a render showing the cake stand with the glass bowl glass applied, the glass bowl, and the cake stand with the original texture.

I'm not sure what is causing this problem. To my eye, it is rendering almost as it the top of the cake stand is solid glass. I have attached the model as well if anyone wants to take a look.
