Wow, that is looking great, Dave. I'm really enjoying the texturing on everything, especially the chairs and the knife. The eraser looks really authentic as well; nice work getting a believable "worn down" look on it.
The only thing I can think of to suggest right now would be some shavings from the cardboard... |

Delineator, thanks, I am currently working on the lighting for this scene but it is taking a bit of time.
I am happy with Vray, I like the quality of the renders. As for as deciding when to use Vray, typically I will model all my objects before deciding what render engine to use but typically use Lightworks at the start and if I get a good result with lightworks I will just continue with it. If my scene requires bounced light, caustics etc. than I move over to Vray. I also like the shaders for Vray.
I think for Architectural visulations it's great, I am sure you have spent many hours trying to correctly light a scene to into account bounced light, I know I have.
As far as lighting adjustments, because of it's ability for Global Illumination you can get away with using less lights and turning down the GI settings is a good way to speed up the renders, the more lights you have ( but I usually don't have to many and area lights take a while sometimes), the lower your GI quality can be so this also helps with speed, typically I use the low setting for GI calulations and the speed and quality is fine.
Hope this helps.

Glad I could help prodigy, it was one of the developers that came up with the solution a while back but I had forgotten until you mentioned it. |

Thanks to everyone else for your comments,
I like the idea of some shavings from the cardboard and some offcuts, may be doable, morgan, madmouse, this alos may help the objects and the model together, seem sort of separate at the moment.
Jack the darn mug has been a pain in my side, that's it it outta here. |

LOL Daybe,
Might just be the diffuse setting. Highly reflective things usually have a low diffuse since they get their color from their surroundings. That said I, I haven't been able to make a good ceramic type material in VRay yet.... :p
BTW, did you use an SSS shader on the eraser? That came out really nice.

Ya I know I haven't either, I will try again but maybe on it's own.
The eraser is just the regular old phong shader with very low shine and no specular settings. |

Jack is right. As higher the diffuse value as less visible are the reflections and vice versa (diffuse not higher as 0.5 is a good value) with fresnel shader.
For some nice reflections the use of hdri would also come in handy.
Increasing the background intensity will brighten up the light intense reflections.
Increasing the reflection amount is another way but I came often up with some overbright reflections and longer render times.

That looks great parva, I will try those settings and see how it looks in the scene, never thought to turn the back intensity up so high. |

Daybe.. but on your render you put hdri reflections??
Maybe if you dont set hdri, the reflections be to softs... |

No HDRI used for the posts so far but I am trying a few different HDRI lighting setup now. |

Daybe.. i recomend this.. its a work arround to get the hdri reflections but a Gi light..
save your GI map, and then loadit..
Now add hdri light with a map offcurse.. you get the hdri reflections but you use gi light...
It be much more faster and you get an excelent result...

Thanks Prodigy, once I decide on a hdri file I will give this a go, speed isn't really an issue at the moment as I can render an image 1000 x 800 in about 20 minutes, with some pretty high settings for GI. |

at my opinion.. "medium" setting its enough. sure i change other settings to fix the noise problems.. but i never use more than medium.. i dont see huge diferences and the speed time go to the hell...
Need help to modeling something?? can i help you... :D |

I think the modeling is about done but thanks for the offer;)
Yes medium with Vray is usually more than enough, this all depends on the lights in the scene of course I find if I am having problems with noise I will just add a low intensity light, usually an infinite light at say 0.1 intensity pointing into the trouble area and this usually does the trick, I find that if GI has to calculate to much light info I end up with noisy renders, most times I use the low setting and that works as well if the scene is lite well enough. |

Thanks, here is my first go at HDRI with this scene, apart from using PS to brighten up the windows this is a straight render with Vray. I think I still need a bit of tweaking but still not bad. It's hard to tell as I have a new flat screen LED monitor and depending how I look at it the contrast changes, miss my CRT sometimes. |

The metals look much crisper because of the HDRI. :)
Think the mug is getting a bit lost now though. There's also may be bit much blue cast though... feels like a rainy day.
Anycase looks like your getting close to finished with this one.
About LCDs, Gotta say I switched to LCD a few years back and haven't looked back. The colors are more vivid and seem to be much more accurate than my old CRTs. The pixels are crisper and actually go in straight lines (not guaranteed on a CRT). Not to mention it takes a lot less space on my desk. ;-)
For laptops they now have "glossy" screens which give you a beautiful clarity and wider view range. I usually opt for the higher res screen though, since I find 1280x800 to be too confining.
One thing you need to make sure of is to use your LCD in native resolution, because they usually look like crap interpolating other resolutions. Fortunately because LCDs are so much clearer than CRT, even on my 15.4" inch laptop 1600x1050 resolution is still easily readable even with small fonts. :D

Looking very nice, a bit dark.
While you're getting the mug shader sorted maybe try a deep orange/red color, a company logo on it might be fun too.
I wonder what a color less like the cardboard models would look like for the table surface that the tools lie on? The glass in the model windows is wild because I wouldn't expect to see it, but I like it. All in all this is a really fun scene. |

That's a really nice render you've got there Daybe!
It does look a tad bit dark in some areas. You may also want to lower the contrast between the objects and the backround. |

Daybe.. i recomend you to erase any noise... incrice...
1) hemisamples to 30.. 50.. its enough...
And the most important.. over all..
The InterpSamples...
I work lot over render settings and i found the most important setting on Vray is InterpSamples..
Set Interpsamples to 50.. to a final render... and can you sayme if you see any noise...
Best Regards... |

Thanks Prodigy, I will be sure to keep that in mind when I get to a final render. The images I have posted were created with the low setting for GI and had a bit of noise also because of the low quality HDR file I was using, I have sinced changed to a better one and also increased the settings and the noise has almost disappeared, I will change both samples to 50 and see what I get.
Thanks |

Alrighty, thought I would post an update, as mentioned before I changed the lighting a wee bit to brighten the scene, I added a logo to the mug and changed the color, still a bit off but way better. I added some bits to both ends of hte image so the eye wouldn't be lead off the edge. It's getting late here so that's it for today hopefully I can finish this tomorrow.
Cheers and thanks to everyone for all your comments, |

Looking very nice; I agree about the cup looking better. It also helps that it now contrasts with the chairs. |

Looks fantastic now! :banana: Nice reflections and a sweet cup (the size from cup and chairs is a bit strange but maybe the pov :D)
prodigy is right. The interpol. samples helps to blur the Irradiance map.
To find the best value for interpol. samples or hemisphere samples is different from scene to scene.
Generally said, if you want max. details increase the hemi samples and you get longer calculation times or increase the interpol. samples and you get blurry but faster GI. |

Very well done scene...
I can envision some architect's office with the display layed out on his table and the tools used in transitioning the display layed out and abandoned after much toil.
Or perhaps the tools were left out in case the "Boss" comes in and says add this or that. :)
All in all, a success and the scene tells a story which is important.
Well crafted and thoughtful. |

It's a Norman Rockwell painting himself painting.... New TS technology in modeling showing the old style.
The coffee cup wouldn't have been a problem the old way....unless you spill it!:) |
